Running a single test in maven -> No tests were executed
You are probably picking up JUnit3 on your classpath somewhere, which effectively disables JUnit4.
Run mvn dependency:tree to find out where it's coming in from and add an exclude to the dependency.
I had the same problem. It was caused by testng dependency that came with junit3. Just add a exclusion statement for it and tests should work.
<dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium</artifactId> <version>2.0b1</version> <exclusions> <exclusion> <groupId>org.testng</groupId> <artifactId>testng</artifactId> </exclusion> </exclusions></dependency>
