+==============================================================================
+13. Testing							*testing*
+
+Vim can be tested after building it, usually with "make test".
+The tests are located in the directory "src/testdir".
+
+There are several types of tests added over time:
+	test33.in		oldest, don't add any more
+	test_something.in	old style tests
+	test_something.vim	new style tests
+
+						*new-style-testing*
+New tests should be added as new style tests.  These use functions such as
+|assert_equal()| to keep the test commands and the expected result in one
+place.
+						*old-style-testing*
+In some cases an old style test needs to be used.  E.g. when testing Vim
+without the |+eval| feature.
+
+Find more information in the file src/testdir/README.txt.
