An atomic method updates dozens of properties. This way all the possible cases can be verified with good queries. Making statements based on opinion; back them up with references or personal experience. Are there any SQL servers that support compiled queries? Is it acceptable to test based on test output data rather than input data in unit tests? A good unit test should leave the database state same as it was before test case execution. Step 6) Create a test runner class to run parameterized test: Code Explanation: Code Line 8: Declaring the main method of the class test which will run our JUnit test.

We can then run the code under test, using some faked input, and compare the output result rows against a set of expected outputs. The second one will make you to navigate to a fixture file (XML in this case, but it can be a simple SQL script as well), but the test remains very clean and un-bloated. We have defined a new type of Dataform script: test.
