tests: add simple (skipped) unit tests for graph_data that may be used to measure performance

Modified by Thomas De Schampheleire to have performance tests in a separate
directory so it is easier to run them, and also added some documentation.

In these commands, the following variables are used::

			




	
	
	
		
 

			




	
	
	
		
 
    KALLITHEA_WHOOSH_TEST_DISABLE=1 - skip whoosh index building and tests

			




	
	
	
		
 
    KALLITHEA_NO_TMP_PATH=1 - disable new temp path for tests, used mostly for testing_vcs_operations

			




	
	
	
		
 

			




	
	
	
		
 
You can run individual tests by specifying their path as argument to py.test.

			




	
	
	
		
 
py.test also has many more options, see `py.test -h`. Some useful options

			




	
	
	
		
 
are::

			




	
	
	
		
 

			




	
	
	
		
 
    -k EXPRESSION         only run tests which match the given substring

			




	
	
	
		
 
                          expression. An expression is a python evaluable

			




	
	
	
		
 
                          expression where all names are substring-matched

			




	
	
	
		
 
                          against test names and their parent classes. Example:

			




	
	
	
		
 
    -x, --exitfirst       exit instantly on first error or failed test.

			




	
	
	
		
 
    --lf                  rerun only the tests that failed at the last run (or

			




	
	
	
		
 
                          all if none failed)

			




	
	
	
		
 
    --ff                  run all tests but run the last failures first. This

			




	
	
	
		
 
                          may re-order tests and thus lead to repeated fixture

			




	
	
	
		
 
                          setup/teardown

			




	
	
	
		
 
    --pdb                 start the interactive Python debugger on errors.

			




	
	
	
		
 
    -s, --capture=no      don't capture stdout (any stdout output will be

			




	
	
	
		
 
                          printed immediately)

			




	
	
	
		
 

			




	
	
	
		
 
Performance tests

			




	
	
	
		
 
^^^^^^^^^^^^^^^^^

			




	
	
	
		
 

			




	
	
	
		
 
A number of performance tests are present in the test suite, but they are

			




	
	
	
		
 
not run in a standard test run. These tests are useful to

			




	
	
	
		
 
evaluate the impact of certain code changes with respect to performance.

			




	
	
	
		
 

			




	
	
	
		
 
To run these tests::

			




	
	
	
		
 

			




	
	
	
		
 
    env TEST_PERFORMANCE=1 py.test kallithea/tests/performance

			




	
	
	
		
 

			




	
	
	
		
 

			




	
	
	
		
 
Contribution guidelines

			




	
	
	
		
 
-----------------------

			




	
	
	
		
 

			




	
	
	
		
 
Kallithea is GPLv3 and we assume all contributions are made by the

			




	
	
	
		
 
committer/contributor and under GPLv3 unless explicitly stated. We do care a

			




	
	
	
		
 
lot about preservation of copyright and license information for existing code

			




	
	
	
		
 
that is brought into the project.

			




	
	
	
		
 

			




	
	
	
		
 
Contributions will be accepted in most formats -- such as pull requests on

			




	
	
	
		
 
Bitbucket, something hosted on your own Kallithea instance, or patches sent by

			




	
	
	
		
 
email to the `kallithea-general`_ mailing list.

			




	
	
	
		
 

			




	
	
	
		
 
When contributing via Bitbucket, please make your fork of

			




	
	
	
		
 
https://bitbucket.org/conservancy/kallithea/ `non-publishing`_ -- it is one of

			




	
	
	
		
 
the settings on "Repository details" page. This ensures your commits are in

			




	
	
	
		
 
"draft" phase and makes it easier for you to address feedback and for project

			




	
	
	
		
 
maintainers to integrate your changes.

Make sure to test your changes both manually and with the automatic tests

			




	
	
	
		
 
before posting.
