+This directory contains tests for various Vim features.
+For testing an indent script see runtime/indent/testdir/README.txt.
+
+If it makes sense, add a new test method to an already existing file.  You may
+want to separate it from other tests with comment lines.
+
+TO ADD A NEW STYLE TEST:
+
+1) Create a test_<subject>.vim file.
+2) Add test_<subject>.res to NEW_TESTS_RES in Make_all.mak in alphabetical
+   order.
+3) Also add an entry "test_<subject>" to NEW_TESTS in Make_all.mak.
+4) Use make test_<subject> to run a single test.
+
+At 2), instead of running the test separately, it can be included in
+"test_alot".  Do this for quick tests without side effects.  The test runs a
+bit faster, because Vim doesn't have to be started, one Vim instance runs many
+tests.
+
+At 4), to run a test in GUI, add "GUI_FLAG=-g" to the make command.
+
+
+What you can use (see test_assert.vim for an example):
+
+- Call assert_equal(), assert_true(), assert_false(), etc.
+
+- Use assert_fails() to check for expected errors.
+
+- Use try/catch to avoid an exception aborts the test.
+
+- Use test_alloc_fail() to have memory allocation fail.  This makes it possible
+  to check memory allocation failures are handled gracefully.  You need to
+  change the source code to add an ID to the allocation.  Add a new one to
+  alloc_id_T, before aid_last.
+
+- Use test_override() to make Vim behave differently, e.g.  if char_avail()
+  must return FALSE for a while.  E.g. to trigger the CursorMovedI autocommand
+  event. See test_cursor_func.vim for an example.
+
+- If the bug that is being tested isn't fixed yet, you can throw an exception
+  with "Skipped" so that it's clear this still needs work.  E.g.: throw
+  "Skipped: Bug with <c-e> and popupmenu not fixed yet"
+
+- See the start of runtest.vim for more help.
+
+
+TO ADD A SCREEN DUMP TEST:
+
+Mostly the same as writing a new style test.  Additionally, see help on
+"terminal-dumptest".  Put the reference dump in "dumps/Test_func_name.dump".
+
+
+OLD STYLE TESTS:
+
+There are a few tests that are used when Vim was built without the +eval
+feature.  These cannot use the "assert" functions, therefore they consist of a
+.in file that contains Normal mode commands between STARTTEST and ENDTEST.
+They modify the file and the result gets writtein in the test.out file.  This
+is then compared with the .ok file.  If they are equal the test passed.  If
+they differ the test failed.
