/*
 * This is the MP0 test suite.
 * The code below is used to evaluate your app during testing, local grading, and official grading.
 * You may not understand all of the code below, but you'll need to have some understanding of how
 * it works so that you can determine what is wrong with your app and what you need to fix.
 *
 * ALL CHANGES TO THIS FILE WILL BE OVERWRITTEN DURING OFFICIAL GRADING.
 * You can and should modify the code below if it is useful during your own local testing,
 * but any changes you make will be discarded during official grading.
 * The local grader will not run if the test suites have been modified, so you'll need to undo any
 * local changes before you run the grader.
 *
 * Note that this means that you should not fix problems with the app by modifying the test suites.
 * The test suites are always considered to be correct.
 *
 * Our test suites are broken into two parts.
 * Unit tests can complete without running your app.
 * They test things like whether a method works properly or the behavior of your API server.
 * Unit tests are usually fairly fast.
 *
 * Integration tests require simulating your app.
 * This allows us to test things like your API client, and higher-level aspects of your app's
 * behavior, such as whether it displays the right thing on the display.
 * Because integration tests require simulating your entire app, they run more slowly.
 *
 * Our test suites will sometimes include both graded and ungraded tests.
 * The graded tests are marking with the `@Graded` annotation which includes a point amount.
 * Ungraded tests do not have this annotation.
 * Some ungraded tests will work immediately, and are there to help you pinpoint regressions:
 * changes you made that might have broken things that were previously working.
 * The ungraded tests below were actually written by me (Geoff) during MP development.
 * Other ungraded tests are simply there to help your development process.
