Testing

The mobiuskt-test module provides a DSL for behavior driven tests and a light re-implementation of Hamcrest style APIs to test mobius loops (See Download).

Behavior testing DSL Example

@Test
fun testAddEvent() {
    UpdateSpec(update)
        .given(0) // given model of 0
        .whenEvent(Event.ADD) // when Event.Add occurs
        .then(assertThatNext(hasModel())) // assert the Next object contains any model
    // No AssertionError, test passed.
}

@Test
fun testAddEventError() {
    UpdateSpec(update)
        .given(0)
        .whenEvent(Event.ADD)
        .then(assertThatNext(hasModel(-1)))
    // AssertionError: expected -1 but received 1, test failed.
}

For more details on the available matchers, see the API documentation.
