+# Changelog
+
+## v3.2.0 - 2020-05-10
+
+- Add support for loading multiple files and directories
+  ([#65](https://github.com/go-testfixtures/testfixtures/pull/65)).
+
+## v3.1.2 - 2020-04-26
+
+- Dump: Fix column order in generated YAML files
+  ([#62](https://github.com/go-testfixtures/testfixtures/pull/62)).
+
+## v3.1.1 - 2020-01-11
+
+- testfixtures now work with both `mssql` and `sqlserver` drivers.
+  Note that [the `mssql` one is deprecated](https://github.com/denisenkom/go-mssqldb#deprecated),
+  though. So try to migrate to `sqlserver` once possible.
+
+## v3.1.0 - 2020-01-09
+
+- Using `sqlserver` driver instead of the deprecated `mssql`
+  ([#58](https://github.com/go-testfixtures/testfixtures/pull/58)).
+
+## v3.0.0 - 2019-12-26
+
+### Breaking changes
+
+- The import path changed from `gopkg.in/testfixtures.v2` to
+  `github.com/go-testfixtures/testfixtures/v3`.
+- This package no longer support Oracle databases. This decision was
+  taken because too few people actually used this package with Oracle and it
+  was the most difficult to test (we didn't run on CI due the lack of an
+  official Docker image, etc).
+- The public API was totally rewritten to be more flexible and ideomatic.
+  It now uses functional options. It differs from v2, but should be easy
+  enough to upgrade.
+- Some deprecated APIs from v2 were removed as well.
+- This now requires Go >= 1.13.
+
+### New features
+
+- We now have a CLI so you can easily use testfixtures to load a sample
+  database from fixtures if you want.
+- Templating via [text/template](https://golang.org/pkg/text/template/)
+  is now available. This allows some fancier use cases like generating data
+  or specific columns dynamically.
+- It's now possible to choose which time zone to use when parsing timestamps
+  from fixtures. The default is the same as before, whatever is set on
+  `time.Local`.
+- Errors now use the new `%w` verb only available on Go >= 1.13.
+
+### MISC
+
+- Travis and AppVeyor are gone. We're using GitHub Actions exclusively now.
+  The whole suite is ran inside Docker (with help of Docker Compose), so it's
+  easy to run tests locally as well.
+
+Check the new README for some examples!
+
+## v2.6.0 - 2019-10-24
+
+- Add support for TimescaleDB
+  ([#53](https://github.com/go-testfixtures/testfixtures/pull/53)).
+
+## v2.5.3 - 2018-12-15
+
+- Fixes related to use of foreign key pragmas on MySQL (#43).
+
+## v2.5.2 - 2018-11-25
+
+- This library now supports [Go Modules](https://github.com/golang/go/wiki/Modules);
+- Also allow `.yaml` (as an alternative to `.yml`) as the file extension (#42).
+
+## v2.5.1 - 2018-11-04
+
+- Allowing disabling reset of PostgreSQL sequences (#38).
+
+## v2.5.0 - 2018-09-07
+
+- Add public function DetectTestDatabase (#35, #36).
+
+## v2.4.5 - 2018-07-07
+
+- Fix for MySQL/MariaDB: ignoring views on operations that should be run only on tables (#33).
+
+## v2.4.4 - 2018-07-02
+
+- Fix for multiple schemas on Microsoft SQL Server (#29 and #30);
+- Configuring AppVeyor CI to also test for Microsoft SQL Server.
+
+---
+
+Sorry, we don't have changelog for older releases 😢.

+# testfixtures
+
+[![GoDoc](https://godoc.org/github.com/go-testfixtures/testfixtures?status.svg)][doc]
+
+> ***Warning***: this package will wipe the database data before loading the
+fixtures! It is supposed to be used on a test database. Please, double check
+if you are running it against the correct database.
+
+> **TIP**: There are options not described in this README page. It's
+> recommended that you also check [the documentation][doc].
+
+Writing tests is hard, even more when you have to deal with an SQL database.
+This package aims to make writing functional tests for web apps written in
+Go easier.
+
+Basically this package mimics the ["Ruby on Rails' way"][railstests] of writing tests
+for database applications, where sample data is kept in fixtures files. Before
+the execution of every test, the test database is cleaned and the fixture data
+is loaded into the database.
+
+The idea is running tests against a real database, instead of relying in mocks,
+which is boring to setup and may lead to production bugs not being caught in
+the tests.
+
+## Installation
+
+First, import it like this:
+
+```go
+import (
+        "github.com/go-testfixtures/testfixtures/v3"
+)
+```
+
+## Usage
+
+Create a folder for the fixture files. Each file should contain data for a
+single table and have the name `<table_name>.yml`:
+
+```
+myapp/
+  myapp.go
+  myapp_test.go
+  ...
+  fixtures/
+    posts.yml
+    comments.yml
+    tags.yml
+    posts_tags.yml
+    ...
+```
+
+The file would look like this (it can have as many record you want):
+
+```yml
+# comments.yml
+- id: 1
+  post_id: 1
+  content: A comment...
+  author_name: John Doe
+  author_email: john@doe.com
+  created_at: 2020-12-31 23:59:59
+  updated_at: 2020-12-31 23:59:59
+
+- id: 2
+  post_id: 2
+  content: Another comment...
+  author_name: John Doe
+  author_email: john@doe.com
+  created_at: 2020-12-31 23:59:59
+  updated_at: 2020-12-31 23:59:59
+
+# ...
+```
+
+An YAML object or array will be converted to JSON. It will be stored on a native
+JSON type like JSONB on PostgreSQL or as a TEXT or VARCHAR column on other
+databases.
+
+```yml
+- id: 1
+  post_attributes:
+    author: John Due
+    author_email: john@due.com
+    title: "..."
+    tags:
+      - programming
+      - go
+      - testing
+    post: "..."
+```
+
+If you need to write raw SQL, probably to call a function, prefix the value
+of the column with `RAW=`:
+
+```yml
+- id: 1
+  uuid_column: RAW=uuid_generate_v4()
+  postgis_type_column: RAW=ST_GeomFromText('params...')
+  created_at: RAW=NOW()
+  updated_at: RAW=NOW()
+```
+
+Your tests would look like this:
+
+```go
+package myapp
+
+import (
+        "database/sql"
+
+        _ "github.com/lib/pq"
+        "github.com/go-testfixtures/testfixtures/v3"
+)
+
+var (
+        db *sql.DB
+        fixtures *testfixtures.Loader
+)
+
+func TestMain(m *testing.M) {
+        var err error
+
+        // Open connection to the test database.
+        // Do NOT import fixtures in a production database!
+        // Existing data would be deleted.
+        db, err = sql.Open("postgres", "dbname=myapp_test")
+        if err != nil {
+                ...
+        }
+
+        fixtures, err := testfixtures.New(
+                testfixtures.Database(db), // You database connection
+                testfixtures.Dialect("postgres"), // Available: "postgresql", "timescaledb", "mysql", "mariadb", "sqlite" and "sqlserver"
+                testfixtures.Directory("testdata/fixtures"), // the directory containing the YAML files
+        )
+        if err != nil {
+                ...
+        }
+
+        os.Exit(m.Run())
+}
+
+func prepareTestDatabase() {
+        if err := fixtures.Load(); err != nil {
+                ...
+        }
+}
+
+func TestX(t *testing.T) {
+        prepareTestDatabase()
+
+        // Your test here ...
+}
+
+func TestY(t *testing.T) {
+        prepareTestDatabase()
+
+        // Your test here ...
+}
+
+func TestZ(t *testing.T) {
+        prepareTestDatabase()
+
+        // Your test here ...
+}
+```
+
+Alternatively, you can use the `Files` option, to specify which
+files you want to load into the database:
+
+```go
+fixtures, err := testfixtures.New(
+        testfixtures.Database(db),
+        testfixtures.Dialect("postgres"),
+        testfixtures.Files(
+                "fixtures/orders.yml",
+                "fixtures/customers.yml",
+        ),
+)
+if err != nil {
+        ...
+}
+
+fixtures, err := testfixtures.NewFiles(db, &testfixtures.PostgreSQL{},
+        "fixtures/orders.yml",
+        "fixtures/customers.yml",
+        // add as many files you want
+)
+if err != nil {
+        ...
+}
+```
+
+With `Paths` option, you can specify the paths that fixtures will load
+from. Path can be directory or file. If directory, we will search YAML files
+in it.
+
+```go
+fixtures, err := testfixtures.New(
+        testfixtures.Database(db),
+        testfixtures.Dialect("postgres"),
+        testfixtures.Paths(
+                "fixtures/orders.yml",
+                "fixtures/customers.yml",
+                "common_fixtures/users"
+        ),
+)
+if err != nil {
+        ...
+}
+```
+
+## Security check
+
+In order to prevent you from accidentally wiping the wrong database, this
+package will refuse to load fixtures if the database name (or database
+filename for SQLite) doesn't contains "test". If you want to disable this
+check, use:
+
+```go
+testfixtures.New(
+        ...
+        testfixtures.DangerousSkipTestDatabaseCheck(),
+)
+```
+
+## Sequences
+
+For PostgreSQL, this package also resets all sequences to a high
+number to prevent duplicated primary keys while running the tests.
+The default is 10000, but you can change that with:
+
+```go
+testfixtures.New(
+        ...
+        testfixtures.ResetSequencesTo(10000),
+)
+```
+
+Or, if you want to skip the reset of sequences entirely:
+
+```go
+testfixtures.New(
+        ...
+        testfixtures.SkipResetSequences(),
+)
+```
+
+## Compatible databases
+
+### PostgreSQL / TimescaleDB
+
+This package has two approaches to disable foreign keys while importing fixtures
+for PostgreSQL databases:
+
+#### With `DISABLE TRIGGER`
+
+This is the default approach. For that use:
+
+```go
+testfixtures.New(
+        ...
+        testfixtures.Dialect("postgres"), // or "timescaledb"
+)
+```
+
+With the above snippet this package will use `DISABLE TRIGGER` to temporarily
+disabling foreign key constraints while loading fixtures. This work with any
+version of PostgreSQL, but it is **required** to be connected in the database
+as a SUPERUSER. You can make a PostgreSQL user a SUPERUSER with:
+
+```sql
+ALTER USER your_user SUPERUSER;
+```
+
+#### With `ALTER CONSTRAINT`
+
+This approach don't require to be connected as a SUPERUSER, but only work with
+PostgreSQL versions >= 9.4. Try this if you are getting foreign key violation
+errors with the previous approach. It is as simple as using:
+
+```go
+testfixtures.New(
+        ...
+        testfixtures.Dialect("postgres"),
+        testfixtures.UseAlterConstraint(),
+)
+```
+
+Tested using the [github.com/lib/pq](https://github.com/lib/pq) driver.
+
+### MySQL / MariaDB
+
+Just make sure the connection string have
+[the multistatement parameter](https://github.com/go-sql-driver/mysql#multistatements)
+set to true, and use:
+
+```go
+testfixtures.New(
+        ...
+        testfixtures.Dialect("mysql"), // or "mariadb"
+)
+```
+
+Tested using the [github.com/go-sql-driver/mysql](https://github.com/go-sql-driver/mysql) driver.
+
+### SQLite
+
+SQLite is also supported. It is recommended to create foreign keys as
+`DEFERRABLE` (the default) to prevent problems. See more
+[on the SQLite documentation](https://www.sqlite.org/foreignkeys.html#fk_deferred).
+(Foreign key constraints are no-op by default on SQLite, but enabling it is
+recommended).
+
+```go
+testfixtures.New(
+        ...
+        testfixtures.Dialect("sqlite"),
+)
+```
+
+Tested using the [github.com/mattn/go-sqlite3](https://github.com/mattn/go-sqlite3) driver.
+
+### Microsoft SQL Server
+
+SQL Server support requires SQL Server >= 2008. Inserting on `IDENTITY` columns
+are handled as well. Just make sure you are logged in with a user with
+`ALTER TABLE` permission.
+
+```go
+testfixtures.New(
+        ...
+        testfixtures.Dialect("sqlserver"),
+)
+```
+
+Tested using the `mssql` and `sqlserver` drivers from the
+[github.com/denisenkom/go-mssqldb](https://github.com/denisenkom/go-mssqldb) lib.
+
+## Templating
+
+Testfixtures supports templating, but it's disabled by default. Most people
+won't need it, but it may be useful to dynamically generate data.
+
+Enable it by doing:
+
+```go
+testfixtures.New(
+        ...
+        testfixtures.Template(),
+
+        // the above options are optional
+        TemplateFuncs(...),
+        TemplateDelims("{{", "}}"),
+        TemplateOptions("missingkey=zero"),
+        TemplateData(...),
+)
+```
+
+The YAML file could look like this:
+
+```yaml
+# It's possible generate values...
+- id: {{sha256 "my-awesome-post}}
+  title: My Awesome Post
+  text: {{randomText}}
+
+# ... or records
+{{range $post := $.Posts}}
+- id: {{$post.Id}}
+  title: {{$post.Title}}
+  text: {{$post.Text}}
+{{end}}
+```
+
+## Generating fixtures for a existing database
+
+The following code will generate a YAML file for each table of the database
+into a given folder. It may be useful to boostrap a test scenario from a sample
+database of your app.
+
+```go
+dumper, err := testfixtures.NewDumper(
+        testfixtures.DumpDatabase(db),
+        testfixtures.DumpDialect("postgres"), // or your database of choice
+        testfixtures.DumpDirectory("tmp/fixtures"),
+        textfixtures.DumpTables( // optional, will dump all table if not given
+          "posts",
+          "comments",
+          "tags",
+        )
+)
+if err != nil {
+        ...
+}
+if err := dumper.Dump(); err != nil {
+        ...
+}
+```
+
+> This was intended to run in small sample databases. It will likely break
+if run in a production/big database.
+
+## Gotchas
+
+### Parallel testing
+
+This library doesn't yet support running tests in parallel! Running tests
+in parallel can result in random data being present in the database, which
+will likely cause tests to randomly/intermittently fail.
+
+This is specially tricky since it's not immediately clear that `go test ./...`
+run tests for each package in parallel. If more than one package use this
+library, you can face this issue. Please, use `go test -p 1 ./...` or run tests
+for each package in separated commands to fix this issue.
+
+If you're looking into being able to run tests in parallel you can try using
+testfixtures together with the [txdb][gotxdb] package, which allows wrapping
+each test run in a transaction.
+
+## CLI
+
+We also have a CLI to load fixtures in a given database.
+Grab it from the [releases page](https://github.com/go-testfixtures/testfixtures/releases)
+and use it like:
+
+```bash
+testfixtures -d postgres -c "postgres://user:password@localhost/database" -D testdata/fixtures
+```
+
+The connection string changes for each database driver.
+
+Use `--help` for all flags.
+
+## Contributing
+
+We recommend you to [install Task](https://taskfile.dev/#/installation) and
+Docker before contributing to this package, since some stuff is automated
+using these tools.
+
+It's recommended to use Docker Compose to run tests, since it runs tests for
+all supported databases once. To do that you just need to run:
+
+```bash
+task docker
+```
+
+But if you want to run tests locally, copy the `.sample.env` file as `.env`
+and edit it according to your database setup. You'll need to create a database
+(likely names `testfixtures_test`) before continuing. Then run the command
+for the database you want to run tests against:
+
+```bash
+task test:pg # PostgreSQL
+task test:mysql # MySQL
+task test:sqlite # SQLite
+task test:sqlserver # Microsoft SQL Server
+```
+
+GitHub Actions (CI) runs the same Docker setup available locally.
+
+## Alternatives
+
+If you don't think using fixtures is a good idea, you can try one of these
+packages instead:
+
+- [factory-go][factorygo]: Factory for Go. Inspired by Python's Factory Boy
+and Ruby's Factory Girl
+- [go-txdb (Single transaction SQL driver for Go)][gotxdb]: Use a single
+database transaction for each functional test, so you can rollback to
+previous state between tests to have the same database state in all tests
+- [go-sqlmock][gosqlmock]: A mock for the sql.DB interface. This allow you to
+unit test database code without having to connect to a real database
+- [dbcleaner][dbcleaner] - Clean database for testing, inspired by
+database_cleaner for Ruby

+** regArg:
+**   Each window function requires an accumulator register (just as an

+**   in an array of accumulator registers - one for each window function
+**   in the WindowCodeArg.pMWin list.
+**
+** eDelete:
+**   The window functions implementation sometimes caches the input rows
+**   that it processes in a temporary table. If it is not zero, this
+**   variable indicates when rows may be removed from the temp table (in
+**   order to reduce memory requirements - it would always be safe just
+**   to leave them there). Possible values for eDelete are:
+**
+**      WINDOW_RETURN_ROW:
+**        An input row can be discarded after it is returned to the caller.
+**
+**      WINDOW_AGGINVERSE:
+**        An input row can be discarded after the window functions xInverse()
+**        callbacks have been invoked in it.
+**
+**      WINDOW_AGGSTEP:
+**        An input row can be discarded after the window functions xStep()
+**        callbacks have been invoked in it.
+**
+** start,current,end
+**   Consider a window-frame similar to the following:
+**
+**     (ORDER BY a, b GROUPS BETWEEN 2 PRECEDING AND 2 FOLLOWING)
+**
+**   The windows functions implmentation caches the input rows in a temp
+**   table, sorted by "a, b" (it actually populates the cache lazily, and
+**   aggressively removes rows once they are no longer required, but that's
+**   a mere detail). It keeps three cursors open on the temp table. One
+**   (current) that points to the next row to return to the query engine
+**   once its window function values have been calculated. Another (end)
+**   points to the next row to call the xStep() method of each window function
+**   on (so that it is 2 groups ahead of current). And a third (start) that
+**   points to the next row to call the xInverse() method of each window
+**   function on.
+**
+**   Each cursor (start, current and end) consists of a VDBE cursor
+**   (WindowCsrAndReg.csr) and an array of registers (starting at
+**   WindowCodeArg.reg) that always contains a copy of the peer values 
+**   read from the corresponding cursor.
+**
+**   Depending on the window-frame in question, all three cursors may not
+**   be required. In this case both WindowCodeArg.csr and reg are set to

-> ***Warning***: this package will wipe the database data before loading the
-fixtures! It is supposed to be used on a test database. Please, double check
-if you are running it against the correct database.
-
-Writing tests is hard, even more when you have to deal with an SQL database.
-This package aims to make writing functional tests for web apps written in
-Go easier.
-
-Basically this package mimics the ["Rails' way"][railstests] of writing tests
-for database applications, where sample data is kept in fixtures files. Before
-the execution of every test, the test database is cleaned and the fixture data
-is loaded into the database.
-
-The idea is running tests against a real database, instead of relying in mocks,
-which is boring to setup and may lead to production bugs not being caught in
-the tests.
-
-## Installation
-
-First, get it:
-
-```bash
-go get -u -v gopkg.in/testfixtures.v2
-```
-
-## Usage
-
-Create a folder for the fixture files. Each file should contain data for a
-single table and have the name `<table_name>.yml`:
-
-```
-myapp/
-  myapp.go
-  myapp_test.go
-  ...
-  fixtures/
-    posts.yml
-    comments.yml
-    tags.yml
-    posts_tags.yml
-    ...
-```
-
-The file would look like this (it can have as many record you want):
-
-```yml
-# comments.yml
-- id: 1
-  post_id: 1
-  content: A comment...
-  author_name: John Doe
-  author_email: john@doe.com
-  created_at: 2016-01-01 12:30:12
-  updated_at: 2016-01-01 12:30:12
-
-- id: 2
-  post_id: 2
-  content: Another comment...
-  author_name: John Doe
-  author_email: john@doe.com
-  created_at: 2016-01-01 12:30:12
-  updated_at: 2016-01-01 12:30:12
-
-# ...
-```
-
-An YAML object or array will be converted to JSON. It can be stored on a native
-JSON type like JSONB on PostgreSQL or as a TEXT or VARCHAR column on other
-databases.
-
-```yml
-- id: 1
-  post_attributes:
-    author: John Due
-    author_email: john@due.com
-    title: "..."
-    tags:
-      - programming
-      - go
-      - testing
-    post: "..."
-```
-
-If you need to write raw SQL, probably to call a function, prefix the value
-of the column with `RAW=`:
-
-```yml
-- id: 1
-  uuid_column: RAW=uuid_generate_v4()
-  postgis_type_column: RAW=ST_GeomFromText('params...')
-  created_at: RAW=NOW()
-  updated_at: RAW=NOW()
-```
-
-Your tests would look like this:
-
-```go
-package myapp
-
-import (
-    "database/sql"
-    "log"
-
-    _ "github.com/lib/pq"
-    "gopkg.in/testfixtures.v2"
-)
-
-var (
-    db *sql.DB
-    fixtures *testfixtures.Context
-)
-
-func TestMain(m *testing.M) {
-    var err error
-
-    // Open connection with the test database.
-    // Do NOT import fixtures in a production database!
-    // Existing data would be deleted
-    db, err = sql.Open("postgres", "dbname=myapp_test")
-    if err != nil {
-        log.Fatal(err)
-    }
-
-    // creating the context that hold the fixtures
-    // see about all compatible databases in this page below
-    fixtures, err = testfixtures.NewFolder(db, &testfixtures.PostgreSQL{}, "testdata/fixtures")
-    if err != nil {
-        log.Fatal(err)
-    }
-
-    os.Exit(m.Run())
-}
-
-func prepareTestDatabase() {
-    if err := fixtures.Load(); err != nil {
-        log.Fatal(err)
-    }
-}
-
-func TestX(t *testing.T) {
-    prepareTestDatabase()
-    // your test here ...
-}
-
-func TestY(t *testing.T) {
-    prepareTestDatabase()
-    // your test here ...
-}
-
-func TestZ(t *testing.T) {
-    prepareTestDatabase()
-    // your test here ...
-}
-```
-
-Alternatively, you can use the `NewFiles` function, to specify which
-files you want to load into the database:
-
-```go
-fixtures, err := testfixtures.NewFiles(db, &testfixtures.PostgreSQL{},
-    "fixtures/orders.yml",
-    "fixtures/customers.yml",
-    // add as many files you want
-)
-if err != nil {
-    log.Fatal(err)
-}
-```
-
-## Security check
-
-In order to prevent you from accidentally wiping the wrong database, this
-package will refuse to load fixtures if the database name (or database
-filename for SQLite) doesn't contains "test". If you want to disable this
-check, use:
-
-```go
-testfixtures.SkipDatabaseNameCheck(true)
-```
-
-## Sequences
-
-For PostgreSQL or Oracle, this package also resets all sequences to a high
-number to prevent duplicated primary keys while running the tests.
-The default is 10000, but you can change that with:
-
-```go
-testfixtures.ResetSequencesTo(10000)
-```
-
-## Compatible databases
-
-### PostgreSQL
-
-This package has two approaches to disable foreign keys while importing fixtures
-in PostgreSQL databases:
-
-#### With `DISABLE TRIGGER`
-
-This is the default approach. For that use:
-
-```go
-&testfixtures.PostgreSQL{}
-```
-
-With the above snippet this package will use `DISABLE TRIGGER` to temporarily
-disabling foreign key constraints while loading fixtures. This work with any
-version of PostgreSQL, but it is **required** to be connected in the database
-as a SUPERUSER. You can make a PostgreSQL user a SUPERUSER with:
-
-```sql
-ALTER USER your_user SUPERUSER;
-```
-
-#### With `ALTER CONSTRAINT`
-
-This approach don't require to be connected as a SUPERUSER, but only work with
-PostgreSQL versions >= 9.4. Try this if you are getting foreign key violation
-errors with the previous approach. It is as simple as using:
-
-```go
-&testfixtures.PostgreSQL{UseAlterConstraint: true}
-```
-
-### MySQL / MariaDB
-
-Just make sure the connection string have
-[the multistatement parameter](https://github.com/go-sql-driver/mysql#multistatements)
-set to true, and use:
-
-```go
-&testfixtures.MySQL{}
-```
-
-### SQLite
-
-SQLite is also supported. It is recommended to create foreign keys as
-`DEFERRABLE` (the default) to prevent problems. See more
-[on the SQLite documentation](https://www.sqlite.org/foreignkeys.html#fk_deferred).
-(Foreign key constraints are no-op by default on SQLite, but enabling it is
-recommended).
-
-```go
-&testfixtures.SQLite{}
-```
-
-### Microsoft SQL Server
-
-SQL Server support requires SQL Server >= 2008. Inserting on `IDENTITY` columns
-are handled as well. Just make sure you are logged in with a user with
-`ALTER TABLE` permission.
-
-```go
-&testfixtures.SQLServer{}
-```
-
-### Oracle
-
-Oracle is supported as well. Use:
-
-```go
-&testfixtures.Oracle{}
-```
-
-## Generating fixtures for a existing database (experimental)
-
-The following code will generate a YAML file for each table of the database in
-the given folder. It may be useful to boostrap a test scenario from a sample
-database of your app.
-
-```go
-err := testfixtures.GenerateFixtures(db, &testfixtures.PostgreSQL{}, "testdata/fixtures")
-if err != nil {
-    log.Fatalf("Error generating fixtures: %v", err)
-}
-```
-
-Or
-
-```go
-err := testfixtures.GenerateFixturesForTables(
-    db,
-    []*TableInfo{
-        &TableInfo{Name: "table_name", Where: "foo = 'bar'"},
-        // ...
-    },
-    &testfixtures.PostgreSQL{},
-    "testdata/fixtures",
-)
-if err != nil {
-    log.Fatalf("Error generating fixtures: %v", err)
-}
-```
-
-> This was thought to run in small sample databases. It will likely break
-if run in a production/big database.
-
-## Contributing
-
-Tests were written to ensure everything work as expected. You can run the tests
-with:
-
-```bash
-# running tests for PostgreSQL
-go test -tags postgresql
-
-# running test for MySQL
-go test -tags mysql
-
-# running tests for SQLite
-go test -tags sqlite
-
-# running tests for SQL Server
-go test -tags sqlserver
-
-# running tests for Oracle
-go test -tags oracle
-
-# running test for multiple databases at once
-go test -tags 'sqlite postgresql mysql'
-
-# running tests + benchmark
-go test -v -bench=. -tags postgresql
-```
-
-Travis runs tests for PostgreSQL, MySQL and SQLite. AppVeyor run for all
-these and also Microsoft SQL Server.
-
-To set the connection string of tests for each database, copy the `.sample.env`
-file as `.env` and edit it according to your environment.
-
-## Alternatives
-
-If you don't think using fixtures is a good idea, you can try one of these
-packages instead:
-
-- [factory-go][factorygo]: Factory for Go. Inspired by Python's Factory Boy
-and Ruby's Factory Girl
-- [go-txdb (Single transaction SQL driver for Go)][gotxdb]: Use a single
-database transaction for each functional test, so you can rollback to
-previous state between tests to have the same database state in all tests
-- [go-sqlmock][gosqlmock]: A mock for the sql.DB interface. This allow you to
-unit test database code without having to connect to a real database
-- [dbcleaner][dbcleaner] - Clean database for testing, inspired by
-database_cleaner for Ruby
