View Source MixTestInteractive.Command.Pattern (mix test.interactive v4.1.1)
Specify one or more filename-matching patterns.
Runs all tests that contain at least one of the patterns as a substring of their filename.
If any pattern looks like a filename/line number pattern, then all of the patterns
are passed on to mix test
directly; no filtering is done. This is because mix test
only supports a single filename-with-line-number pattern at a time.
