  - assumeThatThrownBy
```
public static 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.
    
    Returns:
    
    the created assumption for assertion object.
    
    Since:
    
    2.9.0 / 3.9.0
  - assumeThatCode
```
public static AbstractThrowableAssert<?,? extends Throwable> assumeThatCode(ThrowableAssert.ThrowingCallable shouldRaiseOrNotThrowable)
```
    Allows to capture and then assume on a Throwable (easier done with lambdas).
    The main difference with assumeThatThrownBy(ThrowingCallable) is that this method does not fail if no exception was thrown.
    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 ThrowableAssert.
    
    Since:
    
    3.9.0
  - assumeThatObject
```
public static <T> ProxyableObjectAssert<T> assumeThatObject(T actual)
```
    Creates a new instance of ObjectAssert assumption.
    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.
