NBehave vs SpecFlow Comparison
Background
Recently I've been developing some applicaiton component which was supposed to run with TestNG. Actually, it was another extension of TestNG test. So, in order to test that functionality I had to emulate TestNG suite run within the test body. Well, performing TestNG run programmatically wasn't a problem. It can be done using code like:
import org.testng.TestListenerAdapter;
import org.testng.TestNG;
.......
TestListenerAdapter tla = new TestListenerAdapter();
TestNG testng = new TestNG();
testng.setTestClasses(new Class[] {SomeTestClass.class});
testng.addListener(tla);
testng.run();
.......
where
SomeTestClass is some existing TestNG class. This can be even used with JUnit (which was my case as I mainly used JUnit for the test suite). So, technically TestNG can be executed from JUnit test and vice versa.
Problem
The problem appeared when I tried to run JUnit test performing TestNG run via Maven. Normally tests are picked up using surefire plugin which can be included into Maven pom.xml file with the entry like this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
</plugin>
If you use JUnit only it picks up JUnit tests. In my case I also used JUnit for running test suites but one test required TestNG test class (actually the class with TestNG @Test annotation) as well as I had to add TestNG Maven dependency. In this case only this TestNG class was executed during test run. So, how to let Maven know that I want to run exactly JUnit tests but not TestNG ones while both of them are present within the same Maven project?
