--------------------------------------------------------------------------------

1. A Brief History of usr/src/test

The tests here come in two varieties - tests written from scratch, and tests

that have been ported from the Solaris Test Collection. Not all of the STC

tests have been ported, and a forked repository of those that have been made

publicly available may currently be found here:

https://bitbucket.org/illumos/illumos-stc/

Regardless of origin, all of these tests are executed using the run(1) script

described in the next section.

2. How to Run These Tests

Currently, all the test suites under usr/src/test provide a wrapper script

around run(1). These wrappers allow environment variables to be set up which

may (for example) allow the script to specify which disks may be used by a test

suite, and which must be preserved. Additionally, the wrappers allow options to

run(1) to be passed through so that a user may specify a custom configuration

file for a test suite. For specifics on the options available in the framework

itself, please see the run(1) manpage.

3. How to Develop New Tests

New tests should mimic the directory layout of existing tests to the degree

possible. This includes the following directories:

cmd - Any support binaries or scripts used by the tests in this package.

doc - READMEs or other support documentation to be delivered with the package.

runfiles - Configuration files that dictate how the tests are run.

tests - The tests themselves (see below).

The tests you create will be run, and given a PASS or FAIL status in accordance

with the exit value returned by the test. A test may also be marked SKIPPED in

the event that a prerequisite test is marked FAIL, or marked KILLED in the

event the test times out. Note that there is no way to force a test to be

marked SKIPPED; this is intentional. If a test must be skipped due to

insufficient resources for example, then a wrapper script should be provided

that chooses or creates an appropriate configuration file. The goal of every

run is that every test is marked PASS.

4. Porting Tests from Other Frameworks

STF (Solaris Test Framework)

Porting tests from this framework is relatively straightforward. For the most

part the tests can be arranged in the new directory structure and added to the

configuration file. The template for a configuration file can easily be created

using the -w option to run(1). There are a few other changes that may be

required:

Some STF tests consume the values of variables from the user's environment.

These variables must be set before beginning the test run either manually, or

via a wrapper script.

Groups of tests in STF can automatically source .cfg files specified in the

'stf_description' file that exists in an STF directory. Ported tests that

require any of these variables must manually source the .cfg file instead.

The configuration file of a newly ported test must specify the user the test

should run as, along with the timeout value. In STF, these are also specified

in the 'stf_description' file.
