Gradle test task in JUnit - Test Execution Trace

Test Overview

This test runs a simple JUnit test class using the Gradle test task. It verifies that the test method executes and passes successfully.

Test Code - JUnit 5

JUnit

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

public class SimpleTest {
    @Test
    void testAlwaysPasses() {
        assertTrue(true);
    }
}

// Gradle build file snippet (build.gradle):
//
// plugins {
//     id 'java'
// }
//
// repositories {
//     mavenCentral()
// }
//
// dependencies {
//     testImplementation 'org.junit.jupiter:junit-jupiter:5.9.3'
// }
//
// test {
//     useJUnitPlatform()
// }

// Command to run test:
// ./gradlew test

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Gradle test task starts execution	Gradle initializes and loads the project with JUnit 5 dependency	-	PASS
2	Gradle compiles the SimpleTest.java test class	Compiled test class is ready for execution	-	PASS
3	Gradle runs the test method testAlwaysPasses() using JUnit Platform	JUnit test runner executes the test method	assertTrue(true) is verified	PASS
4	Gradle collects test results and generates test report	Test report shows 1 test executed, 0 failed	Test execution result is PASS	PASS
5	Gradle test task finishes successfully	Build completes with test success status	-	PASS

Failure Scenario

Failing Condition: The test method throws an AssertionError or exception

Execution Trace Quiz - 3 Questions

What does the Gradle test task do first when running tests?

A It compiles the test classes

B It generates the test report

C It runs the test methods

D It cleans the build directory

Key Result

Always ensure your build.gradle file includes the correct test dependencies and configures the test task to use the appropriate test platform to run your tests successfully.
