Is there way to run a single Ambari python unit test using mvn test command?

Cloudera Employee

e.g. mvn -Dtest=TestHDP23StackAdvisor test




is there a specific unit test you're referring to? Ambari unit tests are written in Java using JUnit, so you'd use mvn, just like your example. Here's the development guide, and here's latest build reports For general python unit testing and running single tests, you can do so by referring to Python docs:

The unittest module can be used from the command line to run tests from modules, classes or even individual test methods:

python -m unittest test_module1 test_module2
python -m unittest test_module.TestClass
python -m unittest test_module.TestClass.test_method

Hi Artem,

Thanks a lot for your input. I was looking to test stack advisor recommendations and validations.

e.g. ambari/ambari-server/src/test/python/stacks/2.3/common/

Thanks again!

Here is what worked for me (using python 2.6.6). Still need to investigate how to run the test from ambari root directory.

$ pip install discover
$ export PYTHONPATH=~/git/ambari/ambari-common/src/test/python
$ cd ~/git/ambari/ambari-server/src/test/python/stacks/2.3/common
$ python -m discover -v
