Spock throw exception test

Question

I test Java code with Spock. I test this code:

 try {     Set<String> availableActions = getSthAction()     List<String> goodActions = getGoodAction()     if (!CollectionUtils.containsAny(availableActions ,goodActions )){        throw new CustomException();     } } catch (AnotherCustomExceptio e) {      throw new CustomException(e.getMessage()); } 

I wrote test:

def "some test"() {     given:     bean.methodName(_) >> {throw new AnotherCustomExceptio ("Sth wrong")}     def order = new Order();     when:     validator.validate(order )     then:     final CustomException exception = thrown() } 

And it fails because AnotherCustomExceptio is thrown. But in the try{}catch block I catch this exception and throw a CustomException so I expected that my method will throw CustomException and not AnotherCustomExceptio. How do I test it?

Answer 1

I believe your then block needs to be fixed. Try the following syntax:

then: thrown CustomException 

Answer 2

If you would like to evaluate for instance the message on the thrown Exception, you could do something like:

then: def e = thrown(CustomException) e.message == "Some Message"
