I tried to find unused steps and ended up with overriding a method of
PerformableTree.
This is quita a hack but found 250 unused steps in our code base ;-)
Is there any better method of doing this?
@Override
public void addStories(RunContext context, List<Story> stories) {
super.addStories(context, stories);
Set<Method> usedMethods = new HashSet<>();
Set<Method> existingMethods = new HashSet<>();
List<CandidateSteps> candidateSteps = (List<CandidateSteps>)
ReflectionTestUtils.getField(context, "candidateSteps");
List<StepCandidate> collectCandidates = context.configuration().
stepFinder().collectCandidates(candidateSteps);
for (StepCandidate stepCandidate : collectCandidates) {
existingMethods.add(stepCandidate.getMethod());
}
for (PerformableStory story : getRoot().getStories()) {
for (PerformableScenario scenario : story.getScenarios()) {
NormalPerformableScenario sc = (NormalPerformableScenario)
ReflectionTestUtils.getField(scenario, "normalScenario");
if (sc != null) {
PerformableSteps ps = (PerformableSteps)
ReflectionTestUtils.getField(sc, "steps");
List<Step> steps = (List<Step>) ReflectionTestUtils.
getField(ps, "steps");
for (Step step : steps) {
if (step instanceof StepCreator.ParametrisedStep) {
usedMethods.add((Method) ReflectionTestUtils.
getField(step, "method"));
}
}
}
List<ExamplePerformableScenario> ec = (List<
ExamplePerformableScenario>) ReflectionTestUtils.getField(scenario,
"exampleScenarios");
if (ec != null) {
for (ExamplePerformableScenario eps : ec) {
PerformableSteps ps = (PerformableSteps)
ReflectionTestUtils.getField(eps, "steps");
List<Step> steps = (List<Step>) ReflectionTestUtils.
getField(ps, "steps");
for (Step step : steps) {
if (step instanceof StepCreator.ParametrisedStep
) {
usedMethods.add((Method) ReflectionTestUtils
.getField(step, "method"));
}
}
}
}
}
}
System.out.println(
"#########################################################");
System.out.println("existing " + existingMethods.size());
existingMethods.removeAll(usedMethods);
System.out.println("leftover " + existingMethods.size());
for (Method leftover : existingMethods) {
System.out.println(leftover.toString());
}
System.out.println(
"#########################################################");
}
