Cheat sheet

Along the way we learned a few lessons that makes testing easier

• Create a directory in /src/test/resources/ut/[yourClassName-no extension] where you will store all the test data you want to process. Use KeepTestUtils.getResourceAsJson("file.json",YourTestClass.class) to retrieve values
• Annotate your class with @UnitTest, @IntegrationTest or @PerformanceTest. The first one runs on mvn package the second on on mvn verify while the last one only runs manual
• Use the @Mock annotation instead of mock(classname)
• After the mock definitions, add the Rule using @Rule MockitoRule mockitoRule = MockitoJUnit.rule();
• Keep this sequence:

1. Initialize your Mocks in @BeforeEach, using MockitoAnnotations.initMocks(this);
2. Initialize your local (non mock) variables
3. Define mock behavior. If you switch 2 and 3, be ready for errors

• use KeepTestSubscriber[Json] (see Test Helpers)
• use KeepTestUtils
• if suitable, extend AbstractDatabaseHandlerTest
