A testing library for Sesterl wrapping EUnit

sesterl_testing: A Unit Testing Library for Sesterl Programs

How to use

1. Add the dependency on this library to sesterl.yaml in your project:

   test_dependencies:
     - name: "sesterl_testing"
       source:
         type: "git"
         repository: "https://github.com/gfngfn/sesterl_testing"
         spec:
           type: "branch"
           value: "master"

2. Generate rebar.config from sesterl.yaml:

   $ sesterl config ./

3. Write unit tests (see the next section for detail).

4. Run them:

   $ rebar3 sesterl test

How to write unit tests

Consider testing the following module Mod for instance:

/* -- src/Mod.sest -- */
module Mod = struct

  val add(m, n) = m + n

end

You can write unit tests for Mod by providing the following module:

/* -- test/ModTests.sest -- */
import Mod

module ModTests = #[test] struct

  #[test]
  val add_test() =
    Testing.it("integer addition", fun() ->
      assert Testing.equal(
        -expect 99,
        -got    Mod.add(42, 57),
      )
    end)

end
