Dear Wiki user, You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.
The "HowToContribute" page has been changed by TylerHobbs: https://wiki.apache.org/cassandra/HowToContribute?action=diff&rev1=55&rev2=56 Comment: Update instructions for running tests == Testing and Coverage == Setting up and running system tests: + === Running the Unit Tests === + Simply run `ant` to run all unit tests. To run a specific test class, run `ant -Dtest.name=<ClassName>`. To run a specific test method, run `ant -Dtestsome.name=<ClassName> -Dtestsome.methods=<comma-separated list of method names>`. - === Running the functional tests for Thrift RPC === - 1. Install CQL: `svn checkout https://svn.apache.org/repos/asf/cassandra/drivers; cd drivers/py; python setup.py build; sudo python setup.py install`. - 1. Install the [[http://somethingaboutorange.com/mrl/projects/nose/0.11.1/|nose]] test runner (`aptitude install python-nose`, `easy_install nose`, etc). - 1. Install the Thrift compiler (see InstallThrift) and Python libraries (`cd thrift/lib/py && python setup.py install`). - 1. Generate Cassandra's Python code using `ant gen-thrift-py`. - 1. Build the source `ant clean build`. - 1. Run `nosetests test/system/` from the top-level source directory. - If you need to modify the system tests, you probably only need to care about test/system/test_thrift_server.py. (test/system/__init__.py takes care of spawning new cassandra instances for each test and cleaning up afterwards so they are isolated.) + You can also run tests in parallel: `ant test -Dtest.runners=4`. + + === Running the dtests === + The dtests use [[https://github.com/pcmanus/ccm|ccm]] to test a local cluster. + 1. Install ccm. You can do this with pip by running `pip install ccm`. + 1. Install nosetests. With pip, this is `pip install nose`. + 1. Clone the dtest repo: https://github.com/riptano/cassandra-dtest.git + 1. Set `$CASSANDRA_DIR` to the location of your cassandra checkout. For example: `export CASSANDRA_DIR=/home/joe/cassandra`. Make sure you've already built cassandra in this directory. + 1. Run all tests by running `nosetests` from the dtest checkout. You can run a specific module like so: `nosetests cql_tests.py`. You can run a specific test method like this: `nosetests cql_tests.py:TestCQL.counters_test` === Running the code coverage task === 1. Unzip this one: http://sourceforge.net/projects/cobertura/files/cobertura/1.9.4.1/cobertura-1.9.4.1-bin.zip/download
