Is it possible to skip a scenario with Cucumber-JVM at run-time
I really prefer to be explicit about which tests are being run, by having separate run configurations defined for each environment. I also like to keep the number of tags I use to a minimum, to keep the number of configurations manageable.
I don't think it's possible to achieve what you want with tags alone. You would need to write a custom jUnit test runner to use in place of @RunWith(Cucumber.class). Take a look at the Cucumber implementation to see how things work. You would need to alter the RuntimeOptions created by the RuntimeOptionsFactory to include/exclude tags depending on the browser, or other runtime condition.
Alternatively, you could consider writing a small script which invokes your test suite, building up a list of tags to include/exclude dynamically, depending on the environment you're running in. I would consider this to be a more maintainable, cleaner solution.
I realized that this is a late update to an already answered question, but I want to add one more option directly supported by cucumber-jvm:
@Before //(cucumber one)
public void setup(){
Assume.assumeTrue(weAreInPreProductionEnvironment);
}
"and the scenario will be marked as ignored (but the test will pass) if weAreInPreProductionEnvironment
is false."
You will need to add
import org.junit.Assume;
The major difference with the accepted answer is that JUnit assume failures behave just like pending
Important Because of a bug fix you will need cucumber-jvm release 1.2.5 which as of this writing is the latest. For example, the above will generate a failure instead of a pending in cucumber-java8-1.2.3.jar
It's actually really easy. If you dig though the Cucumber-JVM and JUnit 4 source code, you'll find that JUnit makes skipping during runtime very easy (just undocumented).
Take a look at the following source code for JUnit 4's ParentRunner
, which Cucumber-JVM's FeatureRunner
(which is used in Cucumber
, the default Cucumber runner):
@Override
public void run(final RunNotifier notifier) {
EachTestNotifier testNotifier = new EachTestNotifier(notifier,
getDescription());
try {
Statement statement = classBlock(notifier);
statement.evaluate();
} catch (AssumptionViolatedException e) {
testNotifier.fireTestIgnored();
} catch (StoppedByUserException e) {
throw e;
} catch (Throwable e) {
testNotifier.addFailure(e);
}
}
This is how JUnit decides what result to show. If it's successful it will show a pass, but it's possible to @Ignore
in JUnit, so what happens in that case? Well, an AssumptionViolatedException
is thrown by the RunNotifier
(or Cucumber FeatureRunner
in this case).
So your example becomes:
@Before("@skiponchrome") // this works
public void beforeScenario() {
if(currentBrowser == 'chrome') { // this works
throw new AssumptionViolatedException("Not supported on Chrome")
}
}
If you've used vanilla JUnit 4 before, you'd remember that @Ignore
takes an optional message that is displayed when a test is ignored by the runner. AssumptionViolatedException
carries the message, so you should see it in your test output after a test is skipped this way without having to write your own custom runner.
