251. A Brief History of usr/src/test
26
27The tests here come in two varieties - tests written from scratch, and tests
28that have been ported from the Solaris Test Collection. Not all of the STC
29tests have been ported, and a forked repository of those that have been made
30publicly available may currently be found here:
31
32	https://bitbucket.org/illumos/illumos-stc/
33
34Regardless of origin, all of these tests are executed using the run(1) script
35described in the next section.
36
372. How to Run These Tests
38
39Currently, all the test suites under usr/src/test provide a wrapper script
40around run(1). These wrappers allow environment variables to be set up which
41may (for example) allow the script to specify which disks may be used by a test
42suite, and which must be preserved. Additionally, the wrappers allow options to
43run(1) to be passed through so that a user may specify a custom configuration
44file for a test suite. For specifics on the options available in the framework
45itself, please see the run(1) manpage.
46
473. How to Develop New Tests
48
49New tests should mimic the directory layout of existing tests to the degree
50possible. This includes the following directories:
51
52cmd - Any support binaries or scripts used by the tests in this package.
53doc - READMEs or other support documentation to be delivered with the package.
54runfiles -  Configuration files that dictate how the tests are run.
55tests - The tests themselves (see below).
56
57The tests you create will be run, and given a PASS or FAIL status in accordance
58with the exit value returned by the test. A test may also be marked SKIPPED in
59the event that a prerequisite test is marked FAIL, or marked KILLED in the
60event the test times out. Note that there is no way to force a test to be
61marked SKIPPED; this is intentional. If a test must be skipped due to
62insufficient resources for example, then a wrapper script should be provided
63that chooses or creates an appropriate configuration file. The goal of every
64run is that every test is marked PASS.
65
664. Porting Tests from Other Frameworks
67
68STF (Solaris Test Framework)
69
70Porting tests from this framework is relatively straightforward. For the most
71part the tests can be arranged in the new directory structure and added to the
72configuration file. The template for a configuration file can easily be created
73using the -w option to run(1). There are a few other changes that may be
74required:
75
76Some STF tests consume the values of variables from the user's environment.
77These variables must be set before beginning the test run either manually, or
78via a wrapper script.
79
80Groups of tests in STF can automatically source .cfg files specified in the
81'stf_description' file that exists in an STF directory. Ported tests that
82require any of these variables must manually source the .cfg file instead.
83
84The configuration file of a newly ported test must specify the user the test
85should run as, along with the timeout value. In STF, these are also specified
86in the 'stf_description' file.
