Use ipdb instead of pdb with py.test --pdb option

Question

I want to use ipdb instead of pdb with py.test --pdb option. Is this possible? If so, how?

Clearly, I can use import ipdb; ipdb.set_trace() in the code but that requires to run the test, watch it fail, open a file, find the point of failure in said file, write the above line, re-run the tests. Lots of hassle if I could have something that by passes all of that.

Answer 1

Have you tried pytest-ipdb?

Looks like it's exactly what you are looking for?

It was discontinued in favour of pdb++ which is good. I ended up using using pdb++. – Peninsula

Use this option to set custom debugger:

--pdbcls=IPython.terminal.debugger:Pdb

It can also be included in pytest.ini using addopts:

[pytest]
addopts = "--pdbcls=IPython.terminal.debugger:Pdb"

in a file pytest.ini: [pytest] addopts = --pdbcls=IPython.terminal.debugger:Pdb – Skiplane

So glad to find this! Note you also need the --pdb flag – Kennie

If you have a more recent setup, you may need: [tool.pytest.ini_options] addopts = "--pdbcls=IPython.terminal.debugger:Pdb" – Hartwell

I actually recommend --pdbcls=IPython.terminal.debugger:TerminalPdb instead, which has full tab completion. – Fem
