⚡ Quick Start

Note

There's also a more user friendly and official GameMaker Tutorial for GMTL, I would recommend to check that one out for a better quickstart!

1. Create a new script in your project.
2. Add the following code to the script:

suite(function() {
  // Your section will be inserted here!
});

3. Find a script you want to test, for example, a script that adds two numbers.

/// @function add_two_numbers(a, b)
/// @param {real} a
/// @param {real} b
/// @returns {real}
function add_two_numbers(a, b) {
  return a + b;
}

4. Create a new script anywhere and call it however you want, for example, test_add_two_numbers.

5. Add a section to the suite:

suite(function() {
  section("Add two numbers", function() {
    // Your tests will be inserted here!
  });
});

6. Add some tests to the section:

suite(function() {
  section("Add two numbers", function() {
    test("1 + 1 = 2", function() {
      expect(add_two_numbers(1, 1)).toBe(2);
    });

    test("2 + 2 = 4", function() {
      var _value = add_two_numbers(2, 2);
      expect(_value).toBe(4);
      expect(_value).toBeLessThan(5);
    });

    test("2 + 2 != 10", function() {
      expect(add_two_numbers(1, 2)).never().toBe(10);
    });
  });
});

7. Run project and see the results in the console. You should see something like this:

------- Add two numbers -------
  ✔ 1 + 1 = 2 (0.01ms)
  ✔ 2 + 2 = 4 (0.01ms)
  ✔ 2 + 2 != 10 (0.01ms)

================================================================
======================= Tests Finished! ========================
Test Suites: 1 passed, 1 total. (100% success)
Tests: 3 passed, 3 total. (100% success)
All tests finished in 0.03ms.

8. Done! You have created your first test suite with the GameMaker Testing Library.
