Can PyCharm drop into debug when py.test tests fai

Question

When running tests with py.test there is a --pdb option to enter pdb on failure.

Is there a similar way to enter the debugger when running the same test from within PyCharm?

Answer 1

Follow the steps below to setup the correct run configuration:

1. Run > Edit Configurations...
2. Click the '+' button to add a new configuration.
3. Name the configuration and specify the configuration parameters below:

Script: The path to your py.test executable (find by typing which py.test)

Script Parameters: This parameter is your test case followed by the --pdb option (ie /Users/Johan/projects/misc/testing.py --pdb)

After setting up the configuration, you can run the test case from within PyCharm. If a test case fails, your PyCharm run window will show the pdb prompt.

Answer 2

There is a py.test plugin, pytest-pycharm, that will halt the PyCharm debugger when a test emits an uncaught exception.
