Testing Vim and Vim script			*testing-support*

Expression evaluation is explained in |eval.txt|.  This file goes into details
about writing tests in Vim script.  This can be used for testing Vim itself
and for testing plugins.

1. Testing Vim				|testing|
2. Test functions			|test-functions-details|
3. Assert functions			|assert-functions-details|

==============================================================================
1. Testing Vim						*testing*

Vim can be tested after building it, usually with "make test".
The tests are located in the directory "src/testdir".

						*new-style-testing*
New tests should be added as new style tests.  The test scripts are named
test_<feature>.vim (replace <feature> with the feature under test). These use
functions such as |assert_equal()| to keep the test commands and the expected
result in one place.

Find more information in the file src/testdir/README.txt.
