7,842 PointsI've started the shell for the @Before fixture for these tests. See how the Arrange part is duplicated in both tests, ca
I need help i tried everything.. it's not working....
I need a clear answer.
package com.example;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.*;
public class CalculatorTest {
// declare a Calculator here - don't assign anything to it
@Before
public void setUp() throws Exception {
calculator = new Calculator(); // perfect!
}
@Test
public void addingMultipleNumbersProducesResult() throws Exception {
Calculator calculator = new Calculator(); // remove this, you've already done it
int answer = calculator.addNumbers(1 ,2, 3);
assertEquals(6, answer);
}
@Test
public void addingSingleNumberTotalsAppropriately() throws Exception {
Calculator calculator = new Calculator(); // remove this - you've already done it
int answer = calculator.addNumbers(1);
assertEquals(1, answer);
}
}

At the top of the class create a Calculator
-sized hole in memory by declaring a Calculator
called calculator
. Nothing else. Do this before the setUp()
method.
Then, initialize it inside the @Before
block with calculator = new Calculator();
. Then remove the duplicated lines from the tests; just use the calculator
within those.
I've added some comments in your code.
Make sense?
Steve.
