Assertion Error while running tests #35

Closed Habush closed 7 years ago

Habush commented 7 years ago

I tried to run the test methods in the ModuleIntegrationTest test class. However, the tests fail with the following errors:

java.lang.AssertionError: Expected :2 Actual :0

That is, there are no recommendations being generated by the recommendation engine. What could be the cause of this? How can I resolve this?

omarlarus commented 7 years ago

Hi @Habush ! Do you run the "mvn clean test" command? Or do you run the test class using an IDE?

Thanks, Omar

Habush commented 7 years ago

I am running the test using an IDE, Intellij IDEA to be specific.

EDIT: I ran tests using mvn clean test and still got the same error

omarlarus commented 7 years ago

@Habush can you paste the error log of maven, please?

I have found the cause of the error. I was assigning the wrong label by a mistake and after fixing that it is works. But thank you for taking the time to reply to my comments.
