Before opening a PR and doing a lot of work I wanted to know if you are up for (me) backporting some changes from Glacier to Gleeunit.

The changes in question would be about making gleeunit take a list of module names gleeunit -- test/foo_test.gleam test/foo2_unit.gleam and formatting outputs.

The changes are here mostly https://github.com/inoas/glacier/tree/main/src in the files still named gleeunit*.

My goal would be to remove all the inlined copies fo gleeunit out of glacier again and just make glacier depend on gleeunit.

Hi

Is there any documentation on how to write a helper/setup module for test.
How to import it in the test gleam file.

PS: I am using
gleam: 0.33
gleeunit: 1.0.0

https://hexdocs.pm/gleeunit/gleeunit.html

Still links to https://github.com/gleam-lang/gleeunit

Hi

I would like to run only a subset of tests.
e.g. one test or all tests for one module

With rebar3 it was something like rebar3 eunit --module=day04_test

It is possible with gleam test? How?

Thanks

Hello!
Seems, that default timeout is 5s and no possibility to change it somehow

Dependencies have diverged:

• gleam_stdlib (Hex package)
  the dependency gleam_stdlib in mix.exs is overriding a child dependency:

  In mix.exs:
  {:gleam_stdlib, "~> 0.24", [env: :prod, repo: "hexpm", hex: "gleam_stdlib", compile: "gleam build", app: false]}

  In deps/gleeunit/mix.exs:
  {:gleam_stdlib, "~> 0.19", [env: :prod, hex: "gleam_stdlib", repo: "hexpm", optional: false]}

  Ensure they match or specify one of the above in your deps and set "override: true"
  ** (Mix) Can't continue due to errors on dependencies

Gleeunit reports to be compatible with Gleam 0.32, but it cannot be built on Gleam 0.32:

error: Syntax error
   ┌─ /Users/nicd/svn/glentities/build/packages/gleeunit/src/gleeunit/should.gleam:20:22
   │
20 │       panic as string.concat([
   │                      ^ I was not expecting this.

Expected one of:
a string

Hi

I am not able to find the eunit.hrl when using gleeunit on elixir 1.15.
After doing some digging I found that https://elixirforum.com/t/compiling-eredis-with-elixir-1-15-breaks-compilation/56612/7.

According to Jose, :eunit needs to be added to the extra_applications of the mix.exs of the dependency, which is gleeunit/mix.exs file here. I was not able to find the mix.exs on this repo.

Let me know what to do. I would be happy to open an PR.

When testing javascript code, a failing test function is correctly identified within the error message, but the indicated line number is a line number within should.gleam, not within the test code. This makes it difficult, if not impossible to tell which line within a test function is the failing test, when multiple "should" calls are made within a single test function.

Of course, one solution is to make only one "should" call within each test function, but that's not always feasible. When it's not feasible, determining exactly which line is causing the failure can be a bit frustrating, increasing debugging difficulty

The reason that this occurs is because the "should" functions makes use of panic, but during JS transpilation, that translates to constructing errors with the line number of the panic, which is in the "should" function, not within the test function. (I don't know if this is also the case for Erlang.)

This has already been fixed with 3183660, but there was no release, which would fix the issue on hexdocs

Maybe it could be useful with a link to https://hexdocs.pm/gleeunit in the repo description :)?

current output

❌ 
eyg/functions_test.call_generic_test: Error: This has not yet been implemented

It looks like gleeunit is assuming to be run from the project's root. If we do the following it won't find any test:

gleam new foo
cd foo/test    # Or any other subdirectory
gleam test
# 0 tests run...

This issue was reported on Discord:

exception error: undefined function erlang:binary_to_atom/1
  in function  gleeunit:main/0 (build/dev/erlang/gleeunit/gleeunit.erl, line 18)

This function was added in Erlang 23 https://www.erlang.org/doc/man/erlang.html#binary_to_atom-1

Maybe a second utf8 argument could be added for compatibility with earlier OTP, since binary_to_atom/2 should be present

gleeunit calls erlang:halt/1 to return an exit code for use in CI/CD pipelines.

I am currently using the scaffolded foo_test.gleamfile module to start and stop the external systems. However, cleanup code after gleeunit.main() doesn't run because of the halt. Could have the scaffolded code look like t

gleeunit.main() |> gleeunit.halt()

This would allow folks to break the two apart, adding cleanup code between two functions before a halt.

1. Create new project
2. Edit autogenerated test to:

pub fn hello_world_test() {
  "ööö"
  |> should.equal("äää")
}

3. Run gleam test

Output:

  1) issue_test_test.hello_world_test: module 'issue_test_test'
     Values were not equal
     expected: "äää"
          got: "ööö"

Expected output:

  1) issue_test_test.hello_world_test: module 'issue_test_test'
     Values were not equal
     expected: "äää"
          got: "ööö"

I suspect the reason is somewhere in the interplay of string.inspect and the gleeunit formatters, but I could not pinpoint it.
