+Run Drupal tests from the shell.

+
+All arguments are long options.
+
+ --help Print this page.
+
+ --list Display all available test groups.
+
+ --clean Cleans up database tables or directories from previous, failed,
+ tests and then exits (no tests are run).
+
+ --url Immediately precedes a URL to set the host and path. You will
+ need this parameter if Drupal is in a subdirectory on your
+ localhost and you have not set \$base_url in settings.php. Tests
+ can be run under SSL by including https:// in the URL.
+
+ --php The absolute path to the PHP executable. Usually not needed.
+
+ --concurrency [num]
+
+ Run tests in parallel, up to [num] tests at a time.
+
+ --all Run all available tests.
+
+ --class Run tests identified by specific class names, instead of group names.
+
+ --file Run tests identified by specific file names, instead of group names.
+ Specify the path and the extension (i.e. 'modules/user/user.test').
+
+ --directory Run all tests found within the specified file directory.
+
+ --xml <path>
+
+ If provided, test results will be written as xml files to this path.
+
+ --color Output text format results with color highlighting.
+
+ --verbose Output detailed assertion messages in addition to summary.
+
+ <test1>[,<test2>[,<test3> ...]]
+
+ One or more tests to be run. By default, these are interpreted
+ as the names of test groups as shown at
+ ?q=admin/config/development/testing.
+ These group names typically correspond to module names like "User"
+ or "Profile" or "System", but there is also a group "XML-RPC".
+ If --class is specified then these are interpreted as the names of
+ specific test classes whose test methods will be run. Tests must
+ be separated by commas. Ignored if --all is specified.
