In some newer Linux distributions, env python default to Python 3.0. This patch explicitly uses "python2" instead of just "python" for all scripts that use #! Reported-by: Sanchayan Maity <maitysanchayan@gmail.com> Signed-off-by: Jason Lowe-Power <jason@lowepower.com>
2016-05-26tests: Add test infrastructure as a Python moduleAndreas Sandberg
Implement gem5's test infrastructure as a Python module and a run script that can be used without scons. The new implementation has several features that were lacking from the previous test infrastructure such as support for multiple output formats, automatic runtime tracking, and better support for being run in a cluster environment. Tests consist of one or more steps (TestUnit). Units are run in two stages, the first a run stage and then a verify stage. Units in the verify stage are automatically skipped if any unit run stage wasn't run. The library currently contains TestUnit implementations that run gem5, diff stat files, and diff output files. Existing tests are implemented by the ClassicTest class and "just work". New tests can that don't rely on the old "run gem5 once and diff output" strategy can be implemented by subclassing the Test base class or ClassicTest. Test results can be output in multiple formats. The module currently supports JUnit, text (short and verbose), and Python's pickle format. JUnit output allows CI systems to automatically get more information about test failures. The pickled output contains all state necessary to reconstruct a tests results object and is mainly intended for the build system and CI systems. Since many JUnit parsers parsers assume that test suite names look like Java package names. We currently output path-like names with slashes separating components. Test names are translated according to these rules: * '.' -> '-" * '/' -> '.' The test tool, tests.py, supports the following features: * Test listing. Example: ./tests.py list arm/quick * Running tests. Example: ./tests.py run -o output.pickle --format pickle \ ../build/ARM/gem5.opt \ quick/se/00.hello/arm/linux/simple-timing * Displaying pickled results. Example: ./tests.py show --format summary *.pickle Change-Id: I527164bd791237aacfc65e7d7c0b67b695c5d17c Signed-off-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com> Reviewed-by: Joel Hestness <jthestness@gmail.com>
