One way to get hold of the runtime variables is to use the plugin option. Though it seems like an abuse of the Reporter interface to access the StepDefinitionMatch variable for Cucumber version 1.2.5.
For this create a custom class which implements the Reporter interface.
public class CustomFormatter implements Reporter{
public CustomFormatter() { }
@Override
public void before(Match match, Result result) {}
@Override
public void result(Result result) {}
@Override
public void after(Match match, Result result) {}
@Override
public void match(Match match) {
ThreadLocalStepDefinitionMatch.set((StepDefinitionMatch)match);
}
@Override
public void embedding(String mimeType, byte[] data) {}
@Override
public void write(String text) {}
}
The ThreadLocal class to store the StepDefinitionMatch variable.
public class ThreadLocalStepDefinitionMatch {
private static final ThreadLocal<StepDefinitionMatch> threadStepDefMatch = new InheritableThreadLocal<StepDefinitionMatch>();
private ThreadLocalStepDefinitionMatch() {
}
public static StepDefinitionMatch get() {
return threadStepDefMatch.get();
}
public static void set(StepDefinitionMatch match) {
threadStepDefMatch.set(match);
}
public static void remove() {
threadStepDefMatch.remove();
}
}
The declaration for custom plugin in the runner class
@CucumberOptions(plugin = { "pretty", "html:report", "json:reports.json",
"rerun:target/rerun.txt", "cusform.CustomFormatter" }
Finally accessing the StepDefinitionMatch variable in the step definition class
@When("^user gets count from \"([^\"]*)\"$")
public void userGetsCountFromAndStores(String arg) {
StepDefinitionMatch match = ThreadLocalStepDefinitionMatch.get();
System.out.println(match.getStepName());
System.out.println(match.getPattern());
System.out.println(match.getArguments());
}
The console output gives the following
user gets count from "Car1"
^user gets count from "([^"]*)"$
[Car1]
You are using a pretty old Cucumber version, if you upgrade to Cucumber 2 there will be some changes. The StepDefinitionMatch replaced by PickleTestStep. The declaration in the runner remains the same. The ThreadLocal class change the stored class to PickleTestStep.
The custom formatter becomes
public class CustomFormatter implements Formatter {
public CustomFormatter() {}
private EventHandler<TestStepStarted> stepStartedHandler = new EventHandler<TestStepStarted>() {
@Override
public void receive(TestStepStarted event) {
handleTestStepStarted(event);
}
};
@Override
public void setEventPublisher(EventPublisher publisher) {
publisher.registerHandlerFor(TestStepStarted.class, stepStartedHandler);
}
private void handleTestStepStarted(TestStepStarted event) {
if(event.testStep instanceof PickleTestStep) {
ThreadLocalPickleStep.set((PickleTestStep)event.testStep);
}
}
}
Accessing the StepDefinitionMatch variable in the step definition class
@When("^user gets count from \"([^\"]*)\"$")
public void userGetsCountFromAndStores(String arg) {
System.out.println(ThreadLocalPickleStep.get().getStepText());
System.out.println(ThreadLocalPickleStep.get().getPattern());
System.out.println(ThreadLocalPickleStep.get().getDefinitionArgument());
}
The output is the same as before.
