REQUIRED_FILES¶
List of files required to run the test.  The filenames are relative to the
test WORKING_DIRECTORY unless an absolute path is specified.
If set to a list of files, the test will not be run unless all of the files exist.
Examples¶
Suppose that test.txt is created by test baseTest and none.txt
does not exist:
add_test(NAME baseTest ...)   # Assumed to create test.txt
add_test(NAME fileTest ...)
# The following ensures that if baseTest is successful, test.txt will
# have been created before fileTest is run
set_tests_properties(fileTest PROPERTIES
  DEPENDS baseTest
  REQUIRED_FILES test.txt
)
add_test(NAME notRunTest ...)
# The following makes notRunTest depend on two files. Nothing creates
# the none.txt file, so notRunTest will fail with status "Not Run".
set_tests_properties(notRunTest PROPERTIES
  REQUIRED_FILES "test.txt;none.txt"
)
The above example demonstrates how REQUIRED_FILES works, but it is not the
most robust way to implement test ordering with failure detection.  For that,
test fixtures are a better alternative (see FIXTURES_REQUIRED).
