" This script is sourced while editing the .vim file with the tests.
" When the script is successful the .res file will be created.
" Errors are appended to the test.log file.
"
" To execute only specific test functions, add a second argument.  It will be
" matched against the names of the Test_ funtion.  E.g.:
"	../vim -u NONE -S runtest.vim test_channel.vim open_delay
" The output can be found in the "messages" file.
"
" The test script may contain anything, only functions that start with
" "Test_" are special.  These will be invoked and should contain assert
" functions.  See test_assert.vim for an example.
"
" It is possible to source other files that contain "Test_" functions.  This
" can speed up testing, since Vim does not need to restart.  But be careful
" that the tests do not interfere with each other.
"
" If an error cannot be detected properly with an assert function add the
" error to the v:errors list:
"   call add(v:errors, 'test foo failed: Cannot find xyz')
"
" If preparation for each Test_ function is needed, define a SetUp function.
" It will be called before each Test_ function.
"
" If cleanup after each Test_ function is needed, define a TearDown function.
" It will be called after each Test_ function.
"
" When debugging a test it can be useful to add messages to v:errors:
" 	call add(v:errors, "this happened")
