Description
There doesn't appear to be an expecter for my test, which is to check a tuple with a field which is a list of tuples and check for the specific size of the list, regardless of contents.
Resolution
In any case where there is no obvious or convenient expecter, dequeue directly and use the full Client API to perform the test.
Example
In this case where what is expected is a single tuple with a List(Tuple) field, where the list is unordered and only the size matters, use:
Example
In this case where what is expected is a single tuple with a List(Tuple) field, where the list is unordered and only the size matters, use:
// Collect output tuples for the test
List<Tuple> output = outputStream.dequeue(1);
// Check for no tuples returned
if (output.isEmpty()){ throw new junit.framework.AssertionFailedError("Expected at least one tuple."); }
// Inspect the tuple and throw a JUnit error if the test fails
if (!output.get(0).getList("TupleList").size()==expectedTupleCount) {
String error = String.format("Expected %s tuples in TupleList field.",expectedTupleCount);
throw new junit.framework.AssertionFailedError(error);
}
