Hello there.
I’m wondering if people have any tips for doing TDD with Elixir.
I am specifically wondering if it is possible to configure mix test to only show which tests failed. I find the output to be very noisy (lots of warnings, also shows skipped tests, etc.).
Note that I am accustomed to JavaScript’s Vitest test runner which comes with a TUI that puts test results at the top of the window so you don’t have to search for it. See screenshot at top of https://vitest.dev/
Wonder if there is something similar for Elixir / mix test.

Both of these are good options, the first being closer to what you described:
jdiago
Nothing fancy. When working on a file,
mix test that/file_test.exs. Only runmix testonce I’ve reached a good stopping point.If I’m looking at a specific failure,
mix test that/file_test.exs:5.When I’m using vim, I dynamically map a leader key to write the current file and run a test. If I’m on vs code or zed, I use the integrated terminal because they recognize the
FILE:LINEformat to quickly open test locations or stack traces.edit:
options like
--no-all-warnings,--failedand more can be found here:mr_smith
Thanks both, I think
mix_test_interactiveis indeed what I am looking for.Not quite a TUI, but much more compact.
