Code quality gates in JUnit - Test Execution Trace

Test Overview

This test checks if the code quality gate passes by verifying that the code coverage is above a threshold and no critical issues are found.

Test Code - JUnit 5

JUnit

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

public class CodeQualityGateTest {

    @Test
    public void testCodeQualityGate() {
        // Simulated metrics from code analysis tool
        int coveragePercentage = 85;
        int criticalIssues = 0;

        // Quality gate conditions
        boolean coveragePass = coveragePercentage >= 80;
        boolean noCriticalIssues = criticalIssues == 0;

        assertTrue(coveragePass, "Code coverage is below the required threshold of 80%.");
        assertTrue(noCriticalIssues, "There are critical issues in the code.");
    }
}

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Test starts	JUnit test runner initialized	-	PASS
2	Simulate code coverage metric as 85%	Coverage metric set to 85%	-	PASS
3	Simulate critical issues count as 0	Critical issues count set to 0	-	PASS
4	Check if coverage is >= 80%	Coverage is 85%	assertTrue(coveragePass)	PASS
5	Check if critical issues count is 0	Critical issues count is 0	assertTrue(noCriticalIssues)	PASS
6	Test ends successfully	All assertions passed	-	PASS

Failure Scenario

Failing Condition: Code coverage is below 80% or critical issues count is greater than 0

Execution Trace Quiz - 3 Questions

What does the test verify about code coverage?

A Coverage must be at least 80%

B Coverage must be exactly 85%

C Coverage must be below 80%

D Coverage is not checked

Key Result

Always verify key quality metrics like code coverage and critical issues as part of automated quality gates to prevent low-quality code from progressing.
