AssertJ - Async

Extension for AssertJ API for making asynchronous assertions.

Usage

The entry point for making asynchronous assertion is com.webfleet.assertj.AsyncAssertions class.

To make the assertion first, you need to specify the timeout for your assertion:

• awaitAtMost(Duration.ofSeconds(5))
• awaitAtMost(5, TimeUnit.SECONDS)
• awaitAtMostOneSecond()
• awaitAtMostTwoSeconds()
• awaitAtMostFiveSeconds()
• awaitAtMostFifteenSeconds()
• awaitAtMostThirtySeconds()

Now you can optionally configure following parameters:

• Check interval - the time to be waited in between assertion checks:
  • .withCheckInterval(Duration.ofMillis(500))
  • .withCheckInterval(500, TimeUnit.MILLISECONDS)
  • By default, it's configured to 100ms
• Wait mutex - the object to be used for check interval wait logic:
  • .usingWaitMutex(mutex)
  • It can be used to optimize the wait time with notifyAll() call on state change ending the wait and forcing assertion check

Finally, you can make your assertions by providing lambda consumer function for SoftAssertions object:

awaitAtMostOneSecond().untilAssertions(async -> {
        async.assertThat(condition1).isTrue();
        async.assertThat(condition2).isTrue();
    });

The assertions will be periodically checked in provided check interval duration until success or exceeding the timeout.

When timeout is exceeded AssertionError will be thrown with error from last failed check.
