JUnit testing issue

Question

I'm trying to do a JUnit test to a class in a different package.

The test keeps giving me the error 'Target cannot be resolved to a type'

Here is my JUnit test code

package JUnit_Test;

import static org.junit.Assert.*;

public class TargetTest {

    public void test() {

        Target t = new Target (200,200,50,3,1,0.2,100,100,true);

        t.move();
        assertEquals(t.positionX, 11);
        assertEquals(t.positionY, 15);
    }

}

and here under is the class which I'm getting the method from

import java.awt.Color;
import java.util.Random;

public class Target {
    private Boolean animationdie=false;
    private int size;//size of target
    private int movementschem;//movement scheme target

    private int posy;//were is targets y
    private Boolean isclickable;//can we click
    //for drawing animation circle

    private int angler=0;//radius angle

    private int centerx;//position of centre target

Answer 1

TargetTest is in the JUnit_Test package, the package of Target is unclear, and TargetTest doesn't import Target.

You either need to import Target in TargetTest, or move both in the same package.

Perhaps you just forgot to add this line at the top of Target.java:

package JUnit_Test;

Answer 2

You are trying to test your class in different package. Put your class in one specified package.

Change your constructor to public since currently its having default scope and its has to be imported in JUnit_Test package.

Clean and build your project. It will work.

public Target(int x,int y,int s,int movement,int scenario,Double rad,int centx,int centy, boolean isclickable)

Answer 3

The problem is that the Target class is not in any package.

Put Target in a package and import it into your unit test.

All Java classes belong on a package, even if the default package is allowed by the compiler.

I'll offer some recommendations:

1. Learn and follow the Java coding standards.
2. Put the test and the class in the same package. You won't have this problem.
3. Structure your projects following the Maven directory standard.
