Hello to all test enthusiasts out there, specially to those that
cherish, care or are just keeping an eye on the greenest test
framework there is: Avocado release 0.34.0, aka The Hour of the Star,
is now out!

The main changes in Avocado for this release are:

  • A complete overhaul of the logging and output implementation. This
    means that all Avocado output uses the standard Python logging library
    making it very consistent and easy to understand [1].
  • Based on the logging and output overhaul, the command line test
    runner is now very flexible with its output. A user can choose
    exactly what should be output. Examples include application output
    only, test output only, both application and test output or any
    other combination of the builtin streams. The user visible command
    line option that controls this behavior is --show, which is an
    application level option, that is, it's available to all avocado
    commands. [2]
  • Besides the builtin streams, test writers can use the standard
    Python logging API to create new streams. These streams can be shown
    on the command line as mentioned before, or persisted automatically
    in the job results by means of the --store-logging-stream command
    line option. [3][4]
  • The new avocado.core.safeloader module, intends to make it easier
    to to write new test loaders for various types of Python
    code. [5][6]
  • Based on the new avocado.core.safeloader module, a contrib script
    called avocado-find-unittests, returns the name of
    unittest.TestCase based tests found on a given number of Python
    source code files. [7]
  • Avocado is now able to run its own selftest suite. By leveraging the
    avocado-find-unittests contrib script and the External Runner [8]
    feature. A Makefile target is available, allowing developers to run
    make selfcheck to have the selftest suite run by Avocado. [9]
  • Partial Python 3 support. A number of changes were introduced that
    allow concurrent Python 2 and 3 support on the same code base. Even
    though the support for Python 3 is still incomplete, the avocado
    command line application can already run some limited commands at
    this point.
  • Asset fetcher utility library. This new utility library, and
    INSTRUMENTED test feature, allows users to transparently request
    external assets to be used in tests, having them cached for later
    use. [10]
  • Further cleanups in the public namespace of the avocado Test class.
  • [BUG FIX] Input from the local system was being passed to remote
    systems when running tests with either in remote systems or VMs.
  • [BUG FIX] HTML report stability improvements, including better
    Unicode handling and support for other versions of the Pystache
    library.
  • [BUG FIX] Atomic updates of the "latest" job symlink, allows for
    more reliable user experiences when running multiple parallel jobs.
  • [BUG FIX] The avocado.core.data_dir module now dynamically checks
    the configuration system when deciding where the data directory
    should be located. This allows for later updates, such as when
    giving one extra --config parameter in the command line, to be
    applied consistently throughout the framework and test code.
  • [MAINTENANCE] The CI jobs now run full checks on each commit on
    any proposed PR, not only on its topmost commit. This gives higher
    confidence that a commit in a series is not causing breakage that
    a later commit then inadvertently fixes.

The first video available demonstrates a couple of new features
related to the advanced logging mechanisms, introduced on this
release:
