Testing vim-gitgutter

Run the tests

$ cd test
$ ./test

Add a new test

• Add a test file named like testFoo.vim. It should have this structure:

source helper.vim
call Setup()

" test code here

• Run the tests.
• Inspect output (in foo.actual) from the new test. If good, copy it to foo.expected.
• Run the tests to ensure new test's output is verified.
• Commit changes.

Limitations

• Currently tests are done by writing out a file and comparing it to a known good one.
• There's no support for assertions within the testcase code.
