I have a RunCucumberTest class as described in the JUnit section here and a Cucumber scenario that fails when run from the gutter icon in IntelliJ.
However, why does mvn test build successfully?
[WARNING] Tests run: 482, Failures: 0, Errors: 0, Skipped: 12

I can see in the log that the scenario failed:

After further Googling, I finally figured out the problem was due to having both JUnit and TestNG as dependencies in my project while using the JUnit Cucumber runner. Since I couldn't remove the JUnit and TestNG dependencies as they were inherited from a parent POM, I changed the Cucumber runner to use TestNG instead and it worked.
I later found another, simpler solution: https://stackoverflow.com/a/19928639/4179032.
