    • assertEventsMatchExactly

      @SafeVarargs public final void assertEventsMatchExactly(Condition<? super Event>... conditions)
      Assert that all events contained in this Events object exactly match the provided conditions.

      Conditions can be imported statically from EventConditions and TestExecutionResultConditions.

      Example

       executionResults.testEvents().assertEventsMatchExactly(
     event(test("exampleTestMethod"), started()),
     event(test("exampleTestMethod"), finishedSuccessfully())

    • assertEventsMatchLoosely

      @SafeVarargs public final void assertEventsMatchLoosely(Condition<? super Event>... conditions)
      Assert that all provided conditions are matched by an event contained in this Events object, regardless of order.

      Note that this method performs a partial match. Thus, some events may not match any of the provided conditions.

      Conditions can be imported statically from EventConditions and TestExecutionResultConditions.

      Example

       executionResults.testEvents().assertEventsMatchLoosely(
     event(test("exampleTestMethod"), started()),
     event(test("exampleTestMethod"), finishedSuccessfully())
 );

      Assert that all provided conditions are matched by an event contained in this Events object.

      Note that this method performs a partial match. Thus, some events may not match any of the provided conditions; however, the conditions provided must be in the correct order.

      Conditions can be imported statically from EventConditions and TestExecutionResultConditions.

      Example

       executionResults.testEvents().assertEventsMatchLooselyInOrder(
     event(test("exampleTestMethod"), started()),
     event(test("exampleTestMethod"), finishedSuccessfully())
