AssertJ JUnitSoftAssertions and Guava assertions

Question

I'm addicted to the AssertJ JUnit rule JUnitSoftAssertions. It is really conveniente, you just add it as a test class field

@Rule
public JUnitSoftAssertions softy = new JUnitSoftAssertions();

and you chain several assertThat on it.

Now, I added the dependency for Guava assertions from AssertJ, but looks to me that there is no rule or no way to register the new assertions in the JUnit rule. Hence I must use ugly static imports.

Am I wrong? If so, please explain how to use them in a JUnit rule (without implementing it by myself.

Answer 1

There is no soft assertions support in assertj-guava at the moment but adding it is not too difficult, it only requires a class like:

/**
 * A single entry point for all soft assertions, AssertJ standard assertions and MyProject custom assertions.
 */
// extending make all standard AssertJ assertions available
public class GuavaJUnitSoftAssertions extends JUnitSoftAssertions {

  public <K, V> MultimapAssert<K, V> assertThat(final Multimap<K, V> actual) {
    return proxy(MultimapAssert.class, Multimap.class, actual);
  }

  // add the other guava assertThat methods 
  // ... 
}

Happy to get a contribution for that (I'm a bit busy at the moment).

Hope it helps
