tests

A unit test framework

Defining tests

Tests are registered as event handlers. They will automatically run once on start is finished.

tests.test("lgB run 10", () => {
    motors.largeB.run(10);
    pause(100)
    tests.assertClose("speedB", 10, motors.largeB.speed(), 2)
});

Assertions

The library has various asserts that will register fault. Note that since exceptions are not available, assertion failure do not stop the program execution.

  • assert checks a boolean condition
tests.assert("speed positive", motors.largeB.speed() > 0)
  • assert close checks that a numberical value is within a particular range
tests.assertClose("speed", motors.largeB.speed(), 10, 2)
