Interface WithAssumptions


public interface WithAssumptions
A unified entry point to all assumptions from both the new Java 8 core API and the pre-Java 8 core API. As a convenience, the methods are defined in an interface so that no static imports are necessary if the test class implements this interface.

    • assumeThatThrownBy

      default AbstractThrowableAssert<?,? extends Throwable> assumeThatThrownBy(ThrowableAssert.ThrowingCallable shouldRaiseThrowable)
      Allows to capture and then assume on a Throwable (easier done with lambdas).

      Example :

        @Test
        public void testException() {
          assumeThatThrownBy(() -> { throw new Exception("boom!") }).isInstanceOf(Exception.class)
                                                                    .hasMessageContaining("boom");
       }
      Parameters:
      shouldRaiseThrowable - The ThrowableAssert.ThrowingCallable or lambda with the code that should raise the throwable.

    • assumeThatCode

      default AbstractThrowableAssert<?,? extends Throwable> assumeThatCode(ThrowableAssert.ThrowingCallable shouldRaiseOrNotThrowable)
      Allows to capture and then assume on a Throwable (easier done with lambdas).

      Example :

       ThrowingCallable callable = () -> {
         throw new Exception("boom!");
       };
      
       // assertion succeeds
       assumeThatCode(callable).isInstanceOf(Exception.class)
                               .hasMessageContaining("boom");
      
       // assertion fails
       assumeThatCode(callable).doesNotThrowAnyException();

      This method was not named assumeThat because the java compiler reported it ambiguous when used directly with a lambda :(

      Parameters:
      shouldRaiseOrNotThrowable - The ThrowableAssert.ThrowingCallable or lambda with the code that should raise the throwable.
      Returns:
      the created assumption for assertion object.

    • assumeThatObject

      default <T> ProxyableObjectAssert<T> assumeThatObject(T actual)
      Creates a new instance of ObjectAssert for any object.

      This overload is useful, when an overloaded method of assertThat(...) takes precedence over the generic assumeThat(Object).

      Example:

      Cast necessary because assumeThat(List) "forgets" actual type:

      assumeThat(new LinkedList<>(asList("abc"))).matches(list -> ((Deque<String>) list).getFirst().equals("abc")); 
      No cast needed, but also no additional list assertions:
      assumeThatObject(new LinkedList<>(asList("abc"))).matches(list -> list.getFirst().equals("abc")); 
      Type Parameters:
      T - the type of the actual value.
      Parameters:
      actual - the actual value.
      Returns:
      the created assertion object.
