Troubleshooting

Original Code (Student Code)

Here is the original code (the code that has bugs that we are diagnosing).

The compiler is barking at us about the highlighted line "test.getX()", telling us that "test" does not understand "getX".

public void testMoveToOrigin() {

	PointTests test;

	test.testMoveToOrigin();

	System.out.println("--  testMoveToOrigin  --");
	System.out.println("Expected x: " + 0);
	System.out.println("Expected y: " + 0);

	println("Actual x: " + test.getX());
	println("Actual y: " + test.getY());
}

Reference Example

Let's reference the provided example, we'll put the code and example side-by-side.

We notice several significant differences between our code (right) and the example left)
The example tests a model (type Rectangle) but our code tests a PointTests
The example constructs an object to test (e.g., "new Rectangle()") but our code does not
Our source code uses a isolated println but the example only uses "System.out.println"

//Example for class RectangleTests

public void testSetSmall()  {

	Rectangle rec;

	rec = new Rectangle();

	rec.setSmall();

	System.out.println("-- testSetSmall --");
	System.out.println("Expected Width: " + 5);
	System.out.println("Expected Height: " + 1);
	System.out.println("Actual Width: " + rec.getWidth());
	System.out.println("Actual Height: " + rec.getHeight());
}

//Our code for class PointTests (code with bugs)

public void testMoveToOrigin() {

	PointTests test;

	test.testMoveToOrigin();

	System.out.println("--  testMoveToOrigin  --");
	System.out.println("Expected x: " + 0);
	System.out.println("Expected y: " + 0);

	println("Actual x: " + test.getX());
	println("Actual y: " + test.getY());
}
