Description

GroovyTestCase.shouldFail{} should return the message of the enclosed Exception.
This would allow easier testing that the Exception reveals a meaningful message.

def result = shouldFail(IllegalArgumentException.class){
    throw new IllegalArgumentException('null not allowed')
}
assertEquals 'null not allowed', result

Thanks Dierk for this useful feature. Here is another example:

assert (shouldFail { this.methodThatDoesNotExist(404) }).contains("MissingMethodException")

Ok, actually, there's more to it.

class VarargsTests extends GroovyTestCase {
static int add(int a, int b) { a + b }
void testVarargs() {
shouldFail (MissingMethodException.class) { add(1,"2") }
assert shouldFail ({ add(1,"2") }).contains("MissingMethodException")
shouldFailWithCause (MissingMethodException.class, { add(1,"2") })
}
}
