XML and HTML reports in JUnit - Test Execution Trace

Test Overview

This test runs a simple JUnit test case and generates both XML and HTML reports. It verifies that the test passes and that the reports are created successfully.

Test Code - JUnit 5

JUnit

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

public class SimpleTest {
    @Test
    public void additionTest() {
        assertEquals(4, 2 + 2, "2 + 2 should equal 4");
    }
}

// To generate reports, run tests with Maven or Gradle configured to produce surefire reports.
// Example Maven command: mvn test
// XML reports are generated in target/surefire-reports/
// HTML reports can be generated using plugins like surefire-report-plugin.

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test runner starts and loads SimpleTest class	JUnit test environment initialized	-	PASS
2	Runs additionTest method	Executing test method additionTest	assertEquals(4, 2 + 2)	PASS
3	Test runner completes execution	Test finished with all tests passing	-	PASS
4	JUnit generates XML report in target/surefire-reports/TEST-SimpleTest.xml	XML report file created with test results	XML report contains test case result with status 'passed'	PASS
5	HTML report generated using surefire-report-plugin	HTML report file created in target/site/surefire-report.html	HTML report displays test summary with passed test	PASS

Failure Scenario

Failing Condition: Test assertion fails or report generation fails

Execution Trace Quiz - 3 Questions

What does the XML report generated by JUnit contain?

A Source code of the test class

B Only the test method names without results

C Test case results including pass/fail status

D Compiled bytecode of the tests

Key Result

Always verify that your test assertions are correct and that your build tool is properly configured to generate reports. This helps you quickly identify test results and share them with your team.
