Refactor git diff tests to use a constant on 2.0.x
Review Request #8304 — Created July 21, 2016 and submitted
The diffviewer tests that operated on git diffs were using the same diff
defined over and over again. This patch refactors that diff out into a
constant on the baseTestCaseclass so that is no longer necessary. In
addition, object SHA1s have been corrected in these diffs so that manual
verifification against tests is easier.
Ran unit tests.
