Is there a way to test a specific function or module?

[prestontw]

I know I can run a specific binary with gleam run -m <binary>, but does something similar exist for testing? I have been changing the names of all of the other tests I don't want to run so they aren't picked up by gleam test. I am on gleam 1.4.1.

The "gleam test" command runs the main function in your APPNAME_test module, you can do anything you want in there. Gleam doesn't have an opinions about what your test code does.

Great, thank you! This really helped my mental model of the default testing setup (through gleam new). Is this something that's already documented? I don't think I saw it in the language tour, but this is maybe too in the weeds for the tour. If it's helpful, I would be happy to add some documentation, but I would need some guidance on where to put it.

The tour covers the language rather than the build tool. This bit is explained in the "writing Gleam" tutorial which is linked to at the end of the tour.
