Problem compiling and executing to get the JUnit “Green Bar”

[trpkob]

I have to use Test Driven development with JUnit and am having trouble getting this code to run and compile. Below is my test and production classes.

package edu.hello.test;
import junit.framework.*;

public class MidtermCourseTest extends TestCase {
	void testCourse () {
		Course course = new course ("AAA_AAB", "101");
		
		assertEquals(String "w" , "String "x");
		assertEquals("String "y" , "String "z");
	}
}

package edu.hello.production;

class Course {
	private String department;
	Course (String department, String number) {
		this.department = department;
		this.number = number;
	}
	
	String getDepartment() {
		return department;

        assertEquals(String "w" , "String "x");    // Extra double quote ( " )  ... and String should not be here... java expects an Object "w" is a String Object and will be treated accordingly.
        assertEquals("String "y" , "String "z");   // Two extra double quotes

Please include error messages you've received if you want timely help. assertEquals has several signatures, none of which are (String, String). This will use (Object, Object) and probably(I don't have JUnit installed here to verify) not give you the correct results try assertTrue("y".equals("y")) for example.

Too many '"'. If you see the code blocks above, anything blue is the string, so you've got "w", "String ", "String ", " , ", and "z"

Firstly, what do you want to check with this test? I see you have class named Course, and constructor with departmend and number. So maybe something like this:

assertEquals(course.getDepartment(), "AAA_AAB");
assertEquals(course.getNumber(), "101"); // " " if number is stored as a String

Thank you kuriozal! That is exactly what I am looking to do. I am still getting a compile error however.

Eh why are you writing tests if you don't know very basics of Java?

Java is case sensitive so you can't invoke new course() if you want to invoke new Course().

Additionally, the visibility of Course's constructor and methods is set to default so your test doesn't see them. You have to change it to public.

So:

Course course = new Course ("AAA_AAB", "101");

Thank you for all your help kuriozal! I got it running!
