- ## Method Details

  - ### getCauses

    public abstract List<TestFailure> getCauses()
    Returns the list of causes.

    The result is typically non-empty for multi-assertion failures, e.g. for `org.test4j.MultipleFailuresError`, where the individual failures are in the returned list.

    Returns:
      the cause failures.

  - ### getRawFailure

    public abstract Throwable getRawFailure()
    Returns the raw failure.
    Returns:
      the raw failure

  - ### getDetails

    public abstract TestFailureDetails getDetails()
    Returns structural information about the failure.
    Returns:
      the failure structure

  - ### fromTestAssertionFailure

    public static TestFailure fromTestAssertionFailure(Throwable failure, String expected, String actual)
    Creates a new TestFailure instance from an assertion failure.
    Parameters:
      `failure` - the assertion failure
      `expected` - the expected value for the failure; can be `null`
      `actual` - the actual value for the failure; can be `null`
    Returns:
      the new instance

  - ### fromTestAssertionFailure

    public static TestFailure fromTestAssertionFailure(Throwable failure, String expected, String actual, @Nullable List<TestFailure> causes)
    Creates a new TestFailure instance from an assertion failure.
    Parameters:
      `failure` - the assertion failure
      `expected` - the expected value for the failure; can be `null`
      `actual` - the actual value for the failure; can be `null`
      `causes` - the list of cause failures; can be `null`
    Returns:
      the new instance

  - ### fromFileComparisonFailure

    public static TestFailure fromFileComparisonFailure(Throwable failure, String expected, String actual, byte[] expectedContent, byte[] actualContent, @Nullable List<TestFailure> causes)
    Todo

  - ### fromTestFrameworkFailure

    public static TestFailure fromTestFrameworkFailure(Throwable failure)
    Creates a new TestFailure instance from a test framework failure.
    Parameters:
      `failure` - the failure
    Returns:
      the new instance

  - ### fromTestFrameworkFailure

    public static TestFailure fromTestFrameworkFailure(Throwable failure, @Nullable List<TestFailure> causes)
    Creates a new `TestFailure` instance from a test framework failure.
    Parameters:
      `failure` - the failure
      `causes` - the list of cause failures; can be `null`
    Returns:
      the new instance

  - ### fromTestMethodFailure

    @Incubating public static TestFailure fromTestMethodFailure(Throwable failure)
    Creates a new `TestFailure` instance representing a failure occurring during the execution of a test method.
    Parameters:
      `failure` - the failure
    Returns:
      the new instance
