run - find, execute, and log the results of tests
run [-dgq] [-o outputdir] [-pP script] [-t seconds] [-uxX username] pathname ... run -w runfile [-gq] [-o outputdir] [-pP script] [-t seconds] [-uxX username] pathname ... run -c runfile [-dq] run [-h]
The run command has three basic modes of operation. With neither the -c nor the -w option, run processes the arguments provided on the command line, adding them to the list for this run. If a specified pathname is an executable file, it is added as a test. If a specified pathname is a directory, the behavior depends upon the -g option. If -g is specified, the directory is treated as a test group. See the section on "Test Groups" below. Without the -g option, run simply descends into the directory looking for executable files. The tests are then executed, and the results are logged. With the -w option, run finds tests in the manner described above. Rather than executing the tests and logging the results, the test configuration is stored in a runfile which can be used in future invocations, or edited to modify which tests are executed and which options are applied. Options included on the command line with -w become defaults in the runfile. With the -c option, run parses a runfile, which can specify a series of tests and test groups to be executed. The tests are then executed, and the results are logged. Test Groups A test group is comprised of a set of executable files, all of which exist in one directory. The options specified on the command line or in a runfile apply to individual tests in the group. The exception is options pertaining to pre and post scripts, which act on all tests as a group. Rather than running before and after each test, these scripts are run only once each at the start and end of the test group. Test Execution The specified tests run serially, and are typically assigned results according to exit values. Tests that exit zero and non-zero are marked "PASS" and "FAIL" respectively. When a pre script fails for a test group, only the post script is executed, and the remaining tests are marked "SKIPPED." Any test that exceeds its timeout is terminated, and marked "KILLED." By default, tests are executed with the credentials of the run script. Executing tests with other credentials is done via sudo(1m), which must be configured to allow execution without prompting for a password. Environment variables from the calling shell are available to individual tests. During test execution, the working directory is changed to outputdir. Output Logging By default, run will print one line on standard output at the conclusion of each test indicating the test name, result and elapsed time. Additionally, for each invocation of run, a directory is created using the ISO 8601 date format. Within this directory is a file named log containing all the test output with timestamps, and a directory for each test. Within the test directories, there is one file each for standard output, standard error and merged output. The default location for the outputdir is /var/tmp/test_results. Runfiles The runfile is an ini style configuration file that describes a test run. The file has one section named "DEFAULT," which contains configuration option names and their values in "name = value" format. The values in this section apply to all the subsequent sections, unless they are also specified there, in which case the default is overridden. The remaining section names are the absolute pathnames of files and direcotries, describing tests and test groups respectively. The legal option names are: outputdir = pathname The name of the directory that holds test logs. pre = script Run script prior to the test or test group. pre_user = username Execute the pre script as username. post = script Run script after the test or test group. post_user = username Execute the post script as username. quiet = [True|False] If set to True, only the results summary is printed to standard out. tests = ['filename' [,...]] Specify a list of filenames for this test group. Only the basename of the absolute path is required. This option is only valid for test groups, and each filename must be single quoted. timeout = n A timeout value of n seconds. user = username Execute the test or test group as username.
The following options are available for the run command. -c runfile Specify a runfile to be consumed by the run command. -d Dry run mode. Execute no tests, but print a description of each test that would have been run. -g Create test groups from any directories found while searching for tests. -o outputdir Specify the directory in which to write test results. -p script Run script prior to any test or test group. -P script Run script after any test or test group. -q Print only the results sumary to the standard output. -t n Specify a timeout value of n seconds per test. -u username Execute tests or test groups as username. -w runfile Specify the name of the runfile to create. -x username Execute the pre script as username. -X username Execute the post script as username.
Example 1 Running ad-hoc tests. This example demonstrates the simplest invocation of run. % run my-tests Test: /home/jkennedy/my-tests/test-01 [00:02] [PASS] Test: /home/jkennedy/my-tests/test-02 [00:04] [PASS] Test: /home/jkennedy/my-tests/test-03 [00:01] [PASS] Results Summary PASS 3 Running Time: 00:00:07 Percent passed: 100.0% Log directory: /var/tmp/test_results/20120923T180654 Example 2 Creating a runfile for future use. This example demonstrates creating a runfile with non default options. % run -p setup -x root -g -w new-tests.run new-tests % cat new-tests.run [DEFAULT] pre = setup post_user = quiet = False user = timeout = 60 post = pre_user = root outputdir = /var/tmp/test_results [/home/jkennedy/new-tests] tests = ['test-01', 'test-02', 'test-03']
The following exit values are returned: 0 Successful completion. 1 An error occurred.
