- /**
- * Testing the git commit and log commands
- *
- * Testing the 'commit only' option:
- *
- * I. A single file (f1.txt) specified as part of the --only/ -o option can have
- * one of the following (14) states:
- *
- * <pre>
- * | | expected result
- * ---------------------------------------------------------------------
- * | HEAD DirCache Worktree | HEAD DirCache
- * ---------------------------------------------------------------------
- * f1_1 | - - c | => e: path unknown
- * f1_2 | - c - | => no changes
- * f1_3 | c - - | - -
- * f1_4 | - c c | c c
- * f1_5 | c c - | - -
- * f1_6 | c - c | => no changes
- * f1_7 | c c c | => no changes
- * ---------------------------------------------------------------------
- * f1_8 | - c c' | c' c'
- * f1_9 | c - c' | c' c'
- * f1_10 | c c' - | - -
- * f1_11 | c c c' | c' c'
- * f1_12 | c c' c | => no changes
- * f1_13 | c c' c' | c' c'
- * ---------------------------------------------------------------------
- * f1_14 | c c' c'' | c'' c''
- * </pre>
- *
- * II. Scenarios that do not end with a successful commit (1, 2, 6, 7, 12) have
- * to be tested with a second file (f2.txt) specified that would lead to a
- * successful commit, if it were executed separately (e.g. scenario 14).
- *
- * <pre>
- * | | expected result
- * ---------------------------------------------------------------------------
- * | HEAD DirCache Worktree | HEAD DirCache
- * ---------------------------------------------------------------------------
- * f1_1_f2_14 | - - c | => e: path unknown
- * f1_2_f2_14 | - c - | - -
- * f1_6_f2_14 | c - c | c c
- * f1_7_f2_14 | c c c | c c
- * ---------------------------------------------------------------------------
- * f1_12_f2_14 | c c' c | c c
- * </pre>
- *
- * III. All scenarios (1-14, I-II) have to be tested with different repository
- * states, to check that the --only/ -o option does not change existing content
- * (HEAD and DirCache). The following states for a file (f3.txt) not specified
- * shall be tested:
- *
- * <pre>
- * | HEAD DirCache
- * --------------------
- * *_a | - -
- * *_b | - c
- * *_c | c c
- * *_d | c -
- * --------------------
- * *_e | c c'
- * </pre>
