  - fail
```
public static <V> V fail(java.lang.String message)
```
    Fails a test with the given failure message.
    See Javadoc for fail(String, Throwable) for an explanation of this method's generic return type V.
  - fail
```
public static <V> V fail(java.lang.String message,
                         java.lang.Throwable cause)
```
    Fails a test with the given failure message as well as the underlying cause.
    The generic return type V allows this method to be used directly as a single-statement lambda expression, thereby avoiding the need to implement a code block with an explicit return value. Since this method throws an AssertionFailedError before its return statement, this method never actually returns a value to its caller. The following example demonstrates how this may be used in practice.
```
 Stream.of().map(entry -> fail("should not be called"));
 
```
  - fail
```
public static <V> V fail(java.lang.Throwable cause)
```
    Fails a test with the given underlying cause.
    See Javadoc for fail(String, Throwable) for an explanation of this method's generic return type V.
  - fail
```

```
    Asserts that expected and actual iterables are deeply equal.
    Similarly to the check for deep equality in assertArrayEquals(Object[], Object[]), if two iterables are encountered (including expected and actual) then their iterators must return equal elements in the same order as each other.

 Iterable<Integer> i1 = new LinkedList<>(asList(1, 2, 3));
 assertIterableEquals(i0, i1); // Passes

```

                                    java.util.List<java.lang.String> actualLines)
```
    Asserts that expected list of Strings matches actual list.
    This method differs from other assertions that effectively only check String.equals(Object), in that it uses the following staged matching algorithm:
    For each pair of expected and actual lines do
    1. check if expected.equals(actual) - if yes, continue with next pair
    2. otherwise treat expected as a regular expression and check via String.matches(String) - if yes, continue with next pair
    3. otherwise check if expected line is a fast-forward marker, if yes apply fast-forward actual lines accordingly (see below) and goto 1.
    A valid fast-forward marker is an expected line that starts and ends with the literal >> and contains at least 4 characters. Examples:
    - >>>>
      >> stacktrace >>
      >> single line, non Integer.parse()-able comment >>
      Skip arbitrary number of actual lines, until first matching subsequent expected line is found. Any character between the fast-forward literals are discarded.
    - ">> 21 >>"
      Skip strictly 21 lines. If they can't be skipped for any reason, an assertion error is raised.
    Example showing all three kinds of expected line formats:
```
 │  │  │     caught: AssertionFailedError: single line fail message
 >> S T A C K T R A C E >>
 │  │  │   duration: [\d]+ ms
 │  │  │     status: ✘ FAILED
 │  └─ test() finished after [\d]+ ms\.
 └─ JUnit Jupiter finished after [\d]+ ms\.
 Test plan execution finished. Number of all tests: 1

 Test run finished after [\d]+ ms

    Asserts that execution of the supplied supplier completes before the given timeout is exceeded.
    If the assertion passes then the supplier's result is returned.
    Note: the supplier will be executed in a different thread than that of the calling code. Furthermore, execution of the supplier will be preemptively aborted if the timeout is exceeded.
    Fails with the supplied failure message.

    If necessary, the failure message will be retrieved lazily from the supplied messageSupplier.
