Python API for the Nitrate test case management system

DESCRIPTION

python-nitrate is a Python interface to the Nitrate test case management system. The package consists of a high-level Python module (provides natural object interface), a low-level driver (allows to directly access Nitrate's xmlrpc API) and a command line interpreter (useful for fast debugging and experimenting).

FEATURES

Among the most essential python-nitrate features are:

  • Natural and concise Python interface
  • Custom level of caching & logging
  • Automated status coloring
  • Integrated test suite
  • Utility functions

The main motivation was to hide unnecessary implementation details wherever possible so that using the API is as concise as possible.

Scripts importing python-nitrate can make use of several useful helper functions including info() for logging to stderr, listed() which converts list into nice human readable form, color() for coloring and of course log.{debug,info,warn,error} for logging.

EXAMPLES

Initialize or create an object:

testcase = TestCase(1234)
testrun = TestRun(testplan=<plan>, summary=<summary>)

Default iterators provided for all container objects:

for case in TestRun(1234):
    if case.automated:
        case.status = Status("RUNNING")
        case.update()

Linking case to a plan is as simple as adding an item to a set:

testplan.testcases.add(testcase)
testplan.update()

However, it's still possible to use the low-level driver when a specific features is not implemented yet or not efficient enough:

inject = Nitrate()._server.TestCase.get(46490)

For a quick start you can get some inspiration in the examples directory. The 'matrix.py' script demonstrates how to easily display a matrix view of the test run results for a specific test plan. The 'create.py' script gives a broader overview covering object creation, attribute setting, adjusting logs and caching.

CONFIGURATION

To be able to contact the Nitrate server a minimal user config file ~/.nitrate has to be provided in the user home directory:

[nitrate]
url = https://nitrate.server/xmlrpc/

TEST SUITE

The high-level interface has an integrated test suite, which can be easily run against a stage server instance. For this a couple of objects needs to be prepared and already existing on the server so that we can check valid results. For detailed information about what data has to be prepared see the module documentation.
