No tests found by neotest-python

[NostraDavid]

Had trouble getting this adapter to find my tests and got the "no tests found" notification.

I checked the log, as mentioned in this issue on neotest itself, but found nothing wrong (other than there was no mention that files were found, which started to ring a bell).

I had this code in my config, because part of it was part of the example config in the README.md:

is_test_file = function(file_path)
  return vim.startswith(file_path, "test_")
end,

Turns out this doesn't work. Nor did this:

is_test_file = function(file_path)
  return file_path:find("^test_") ~= nil
end,

Solution:

Don't use is_test_file, by either removing the is_test_file or commenting it out! The default behavior works just fine.

So yes, my problem has already been solved.

However, to ensure others don't need to suffer the same problem, I figure I'd post it here :)

However, maybe you want to add an example of a working version to the README, or perhaps add a mention that if no tests are found, it would help to turn the function off?

The default version already does exactly what you want and the README states the configuration values are optional. I don't see any need to add an example that people will unfortunately probably blindly copy and paste with no need, hence why the given one is not valid lua.
