Part 2 - Chapter 1: Helpful JUnit Annotations

Supporting JUnit4 Examples

• You can run the tests with mvn clean test
• These examples are fully described in my Openclassrooms course on testing in Java.

Here are some things for your to try out:

• Run just the conversion tests with mvn -Dgroups='com.openclassrooms.testing.Categories$ConversionTests' test
• Run all the tests in your IDE

Don't forget the quotes around the class name or the $ might mean something completely different on your command line!

Your Fun Challenge

• We have a failing test. Run the tests and find it.
• @Ignore this test so it skips.
• Run your tests again.
• Complete and fix the test!

Remember to remove the @Ignore when you're done!

Tips

• Uncomment the @Ignore already in the code
• Write the Arrange, Act and Assert to prove that 1000 meters converts to 1KM.
