Changes in version 0.8

Experimental version released on May 7th, 2010.

  • Test programs no longer run several test cases in a row. The execution
    of a test program now requires a test case name, and that single test
    case is executed. To execute several test cases, use the atf-run utility
    as usual.
  • Test programs no longer fork a subprocess to isolate the execution of
    test cases. They run the test case code in-process, and a crash of the
    test case will result in a crash of the test program. This is to ease
    debugging of faulty test cases.
  • Test programs no longer isolate their test cases. This means that they
    will not create temporary directories nor sanitize the environment any
    more. Yes: running a test case that depends on system state by hand will
    most likely yield different results depending on where (machine,
    directory, user environment, etc.) it is run. Isolation has been moved
    to atf-run.
  • Test programs no longer print a cryptic format (application/X-atf-tcs)
    on a special file channel. They can now print whatever they want on the
    screen. Because test programs can now only run one test case every time,
    providing controlled output is not necessary any more.
  • Test programs no longer write their status into a special file
    descriptor. Instead, they create a file with the results, which is later
    parsed by atf-run. This changes the semantics of the -r flag.
  • atf-run has been adjusted to perform the test case isolation. As a
    result, there is now a single canonical place that implements the
    isolation of test caes. In previous releases, the three language
    bindings (C, C++ and shell) had to be kept in sync with each other (read:
    not a nice thing to do at all). As a side effect of this change, writing
    bindings for other languages will be much, much easier from now on.
  • atf-run forks test programs on a test case basis, instead of on a test
    program basis as it did before. This is to provide the test case
    isolation that was before implemented by the test programs themselves.
  • Removed the atf-exec tool. This was used to implement test case
    isolation in atf-sh, but it is now unnecessary.
  • It is now optional to define the descr meta-data property. It has been
    proven to be mostly useless, because test cases often carry a descriptive
    name of their own.
