Create a JUnit test suite and test runner for the DVD Collection Project. The rest of the prompt is screenshotted below. Both DVD$.$java and DVDCollection.java classes are also screenshotted below. The DVDConsoleUI.java class is written out here below.

Please fully complete this Java JUnit test project and create source files for all classes, tests, test suite, and the test runner. Also provide screenshots of the test runs and results.
