The following table describes the parameter commands. 
		
			| Command | Description | 
		
			| -ttestsuiteor
 
 -testsuitetestsuite | Specifies the test suite. | 
		
			| -keywordskeyword-expr | Restricts the set of tests to be run based on keywords associated with tests in the test suite. | 
		
			| -statusstatus-expr | Includes or excludes tests from a test run based on their status from a previous test run. Valid status expressions are error, failed, not run, and passed. | 
		
			| -excludeListexclude-list-file | Specifies an exclude list file. Exclude list files contain a list of tests that are not to be run. Exclude list files conventionally use the .jtxextension and are normally supplied with a test suite. | 
		
			| -envFileenvironment-file | Specifies an environment file that contains information used by the harness to run tests in your computing environment. You can specify an environment file for the harness to use when running tests. | 
		
			| -envenvironment | Specifies a test environment from an environment file. | 
		
			| -concurrencynumber | Specifies the number of tests run concurrently. If you are running the tests on a multi-processor computer, concurrency can speed your test runs. | 
		
			| -timeoutFactornumber | Increases the timeout limit by specifying a value in the time factor option. The timeout limit is the amount of time that the harness waits for a test to complete before moving on to the next test. Each test's timeout limit is multiplied by the time factor value. For example, if you specify a value of 2, the timeout limit for tests with a 10 basic time limit becomes 20 minutes. | 
		
			| -rreport-directoryor
 
 -reportreport-directory | Specifies the directory where the harness writes test report files. If this path is not specified, the reports are written to a directory named report in the directory from which you started the harness. | 
		
			| -wwork-directoryor
 
 -workDirworkDirectory | Specifies a work directory for the test run. Each work directory is associated with a test suite and stores its test result files in a cache. |
