      7  1.1  martin This part of the source tree contains regression tests. There are special
      8  1.1  martin make targets and rules to follow. Most of these, however, are currently not
      9  1.1  martin enforced, and most tests available are not conforming.
     10  1.1  martin 
     11  1.1  martin We hope to fix this someday. If you add new tests, please try to be conforming.
     12  1.1  martin 
     13  1.1  martin What is a regression test?
     14  1.1  martin 
     15  1.1  martin   A regression test is run by a makefile in a test directory (see below).
     16  1.1  martin   Each makefile may run multiple tests.
     17  1.1  martin 
     18  1.1  martin What is a test directory?
     19  1.1  martin 
     20  1.1  martin   A directory in this part of the tree is a regression test directory. It
     21  1.1  martin   contains a Makefile which implements the additional "regress" target,
     22  1.1  martin   and runs all it's regression tests during this target.
     23  1.1  martin 
     24  1.1  martin May the make progress be stopped on failures?
     25  1.1  martin 
     26  1.1  martin   No, the "make regress" target should succeed, unless some regression 
     27  1.1  martin   binaries could not be build, disk is full or other catastrophic failures
     28  1.1  martin   outside of the tested subsystem happen. A failing regression test should
     29  1.1  martin   log the failure (see below), but not make the target itself fail.
     30  1.1  martin 
     31  1.1  martin What are the possible results of a regression test?
     32  1.1  martin 
     33  1.1  martin   A test may either
     34  1.1  martin 
     35  1.1  martin   - succeed, in which case it logs "PASSED" (see below for logging details)
     36  1.1  martin   - fail, in which case it logs "FAILED"
     37  1.1  martin   - not be able to run, in which case it logs "SKIPPED" and the reason
     38  1.1  martin     for the skip in the comment field (see below)
     39  1.1  martin 
     40  1.1  martin   Typical reasons for tests to not being run are missing kernel options,
     41  1.1  martin   or missing privileges (test needs root, "make regress" is invoked by
     42  1.1  martin   mere mortal or vice versa). A test may not fail because of such
     43  1.1  martin   environmental issues, it must detect and properly log the problem.
     44  1.1  martin 
     45  1.1  martin   If a test directory contains tests that may be skipped, it should have
     46  1.1  martin   a README file explaining the prerequisites (e.g. needed kernel options)
     47  1.1  martin 
     48  1.1  martin   In future, we will mark affected makefiles and optimize run/skipped test
     49  1.1  martin   during repeated runs with differing privileges - but currently there is no
     50  1.1  martin   make framework in place to handle this.
     51  1.1  martin 
     52  1.1  martin How and when does a test log results?
     53  1.1  martin 
     54  1.1  martin   If the make/environment variable ${REGRESS_LOG} is defined, the final
     55  1.1  martin   results (and only those) should be logged to the file named by that
     56  1.1  martin   variable. We will, in the future, add make targets for this purpose.
     57  1.1  martin   The log format is line oriented, one line used per test. Each line
     58  1.1  martin   consists of the directory where the Makefile lives, followed by the
     59  1.1  martin   test name and the result (see above: PASSED, FAILED, SKIPPED).
     60  1.1  martin   Following this an optional comment may be added. For SKIPPED tests the
     61  1.1  martin   comment is not optional. Fields are separated by spaces.
