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.

2.9.0 / 3.9.0

assumeThat

default AbstractOffsetTimeAssert<?> assumeThat(OffsetTime offsetTime)

Creates a new instance of OffsetTimeAssert assumption.

Parameters:

offsetTime - the actual value.

Returns:

the created assumption for assertion object.

Since:

2.9.0 / 3.9.0

assumeThat

default AbstractOffsetDateTimeAssert<?> assumeThat(OffsetDateTime offsetDateTime)

Creates a new instance of OffsetDateTimeAssert assumption.

Parameters:

offsetDateTime - the actual value.

Returns:

the created assumption for assertion object.

Since:

2.9.0 / 3.9.0

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.

Returns:

the created assumption for assertion object.

Since:

2.9.0 / 3.9.0

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.

Since:

2.9.0 / 3.9.0

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.

Since:

3.12.0

assumeThat

default <T> ProxyablePredicateAssert<T> assumeThat(Predicate<T> predicate)

Creates a new instance of PredicateAssert assumption.

Type Parameters:

T - the Predicate type.

Parameters:

predicate - the Predicate to test

Returns:

the created assumption for assertion object.

Since:

3.9.0

assumeThat

default IntPredicateAssert assumeThat(IntPredicate intPredicate)

Creates a new instance of IntPredicateAssert assumption.

Parameters:

intPredicate - the IntPredicate to test

Returns:

the created assumption for assertion object.

Since:

3.9.0

assumeThat

default LongPredicateAssert assumeThat(LongPredicate longPredicate)

Creates a new instance of LongPredicateAssert assumption.

Parameters:

longPredicate - the LongPredicate to test

Returns:

the created assumption for assertion object.

Since:

3.9.0

assumeThat

default DoublePredicateAssert assumeThat(DoublePredicate doublePredicate)

Creates a new instance of DoublePredicateAssert assumption.

Parameters:

doublePredicate - the DoublePredicate to test

Returns:

the created assumption for assertion object.

Since:

3.9.0

assumeThat

default AbstractUrlAssert<?> assumeThat(URL url)

Creates a new instance of UrlAssert assumption.

Parameters:

url - the actual value.

Returns:

the created assumption for assertion object.

Since:

2.9.0 / 3.9.0

assumeThat

default AbstractUriAssert<?> assumeThat(URI uri)

Creates a new instance of UriAssert assumption.

Parameters:

uri - the actual value.

Returns:

the created assumption for assertion object.

Since:

2.9.0 / 3.9.0

assumeThat

default <ELEMENT> AbstractSpliteratorAssert<?,ELEMENT> assumeThat(Spliterator<ELEMENT> spliterator)

Creates a new instance of SpliteratorAssert assumption.

Type Parameters:

ELEMENT - the type of the elements.

Parameters:

spliterator - the actual value.

Returns:

the created assumption for assertion object.
