 # This file lists the webdriver tests that run as a part of the functional test
 # suite.
 #
 # Tests can be enabled on a per-platform basis. Tests not listed here will
 # not be run.
 #
 # Test names can be specified in any of the following ways:
 # 1. as a module, in which case all tests in that module will be run
 #      example: 'test_basic'
 # 2. or as a test case, in which case all tess in that test case will be run
 #      example: 'test_basic.SimpleTest'
 # 3. or as an individual test
 #      example: 'test_basic.SimpleTest.testCanOpenGoogle'
 #
 # Tests beginning with '-' will be excluded.  This can be used to enforce
 # exclusions for a particular platform.
 
 # Most of these tests are disabled because they involve not yet implemented
 # features. See bug 71237.
