Class CatchThrowableHamcrestMatchers

java.lang.Object

com.googlecode.catchexception.throwable.apis.CatchThrowableHamcrestMatchers

public class CatchThrowableHamcrestMatchers
extends Object

Provides some Hamcrest matchers to match some throwable properties.

EXAMPLE:

// given an empty list
List myList = new ArrayList();

// when we try to get the first element of the list
catchThrowable(myList).get(1);

// then we expect an IndexOutOfBoundsThrowable with message "Index: 1, Size: 0" 
assertThat(caughtThrowable(),
  allOf(
    is(IndexOutOfBoundsThrowable.class), 
    hasMessage("Index: 1, Size: 0"),
    hasNoCause()
  )
);

To combine the standard Hamcrest matchers, your custom matchers, these matchers, and other matcher collections (as JUnitMatchers) in a single class follow the instructions outlined in Sugar generation.

Hint: This class might use hamsandwich in the future but as long as hamsandwich is not in any public maven repository, this class will not use hamsandwich.

Since:

1.2.0
