Test result publishing in JUnit - Test Execution Trace

Test Overview

This test runs a simple JUnit test case and verifies that the test result is published correctly as a pass or fail in the test report.

Test Code - JUnit

JUnit

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.assertEquals;

public class CalculatorTest {

    @Test
    public void testAddition() {
        int result = 2 + 3;
        assertEquals(5, result, "2 + 3 should equal 5");
    }
}

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test runner starts and loads CalculatorTest class	JUnit test environment initialized, test class loaded	-	PASS
2	JUnit invokes testAddition() method	Inside testAddition method, variables initialized	-	PASS
3	Calculate result = 2 + 3	result variable holds value 5	-	PASS
4	Assert that result equals 5 using assertEquals	Assertion compares expected 5 with actual 5	assertEquals(5, result) passes	PASS
5	JUnit marks testAddition as PASSED	Test report updated with pass status for testAddition	Test result published as PASS in report	PASS

Failure Scenario

Failing Condition: If the calculation result is not equal to 5

Execution Trace Quiz - 3 Questions

What does the assertion in the test verify?

A That the test method runs without exceptions

B That the sum of 2 and 3 equals 5

C That the test report file is created

D That the test class is loaded by JUnit

Key Result

Always include clear assertions in your tests so the test framework can publish accurate pass or fail results in the test report.
