Pure tests

If your tests do not require any capability provided by effect-types, you can use a simplified interface FunSuite, which comes with a single test method and does not allow effectful tests.

Tests in FunSuite are executed sequentially and without the performance overhead of effect management.

object CatsFunSuite extends weaver.FunSuite {
  test("asserts") { expect(Some(5).contains(5)) }

  test("fails")   { expect(Some(25).contains(5)) }

  test("throws")  { throw new RuntimeException("oops") }
}
