Test Classes

The tests you write will need to be contained within a test class. Using our framework will require you to extend one of our built-in test classes. Currently, that means extending either BaseTest or BaseRandomTest.

BaseTest

This is used for all tests.

What it tests:

1. That the output of the program matches the structure defined by the "Test Sentence".

BaseRandomTest

This is used when your test contains random clauses (i.e. RandomInteger).

Note: BaseRandomTest extends BaseTest so all functionality from BaseTest remains even if you use BaseRandomTest.

What it tests:

1. Everything that BaseTest does.
2. That random values in the output behave randomly within their boundaries (i.e. Check that a RandomInteger(1, 10) is actually random and not just hardcoded).
3. That random values in the output are always within their set ranges (i.e. Check that a RandomInteger(1, 10) is within the range [1-10)).

Setting up a test class

Regardless of which test class you extended, there are 2 methods you absolutely must specify. Your IDE should warn you if you forget, though. These 2 mandatory methods are: public Clause[] testSentence() and public void runMain()

testSentence()

This should return an array of Clause objects specifying the structure of the output the program should create. Example:

public Clause[] testSentence() {
    return new Clause[]{
        new StringLiteral("This is a random test with retrieval."),
        new NewLine(),
        new RandomInteger(5, 10, "important number"),
    };
}

runMain()

This method should simply call and run the main method of the class you are intending to test. For example, let's say we want to test the output of a class called Example:

public void runMain() {
    Example.main(new String[0]);
}
