From: Christian Halstrick Date: Fri, 4 Jun 2010 22:18:17 +0000 (+0200) Subject: Refactor ReadTreeTest to allow testing other checkout classes X-Git-Tag: v0.9.1~210^2 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=eca29464574e9551d978c3215f3d981415e31868;p=jgit.git Refactor ReadTreeTest to allow testing other checkout classes ReadTreeTest contains a lot of useful tests for "checkout" implementations. But ReadTreeTest was hardcoded to test only WorkDirCheckout. This change doesn't add/modify any tests semantically but refactors ReadTreeTest so that a different implementations of checkout can be tested. This was done to allow DirCacheCheckout to be tested without rewriting all these tests.
