JUnit CTRF Extension

A JUnit 5 extension that generates test reports following the standardized CTRF (Common Test Report Format) specification.

What is CTRF?

CTRF is a universal JSON test report schema that addresses the lack of a standardized format for JSON test reports.

Consistency Across Tools: Different testing tools and frameworks often produce reports in varied formats. CTRF ensures a uniform structure, making it easier to understand and compare reports, regardless of the testing tool used.

Language and Framework Agnostic: It provides a universal reporting schema that works seamlessly with any programming language and testing framework.

Facilitates Better Analysis: With a standardized format, programmatically analyzing test outcomes across multiple platforms becomes more straightforward.

Features

• Generates CTRF-compliant JSON test reports for JUnit 5 tests
• Captures test status, duration, and failure details
• Supports customization of report content via configuration
• Tracks and includes environment information
• Handles parallel test execution

Getting Started

Add Dependency

To use the JUnit CTRF Extension in your project, add the following dependency:

Gradle

Add to your build.gradle file:

repositories {
    mavenCentral()
}

dependencies {
    implementation 'io.github.alexshamrai:junit-ctrf-extension:0.3.1'
}

Maven

Add to your pom.xml file:

<dependency>
    <groupId>io.github.alexshamrai</groupId>
    <artifactId>junit-ctrf-extension</artifactId>
    <version>0.3.1</version>
</dependency>

Register JUnit Extension

To use the JUnit CTRF Extension, you need to register it in your JUnit test class. You can do this by adding the @ExtendWith annotation to your test class:

@ExtendWith(CtrfExtension.class)
public class MyTest {
    
    @Test
    void testExample() {
        // Your test code
    }
}

For more details on JUnit extensions, see the JUnit 5 User Guide.

Configure Properties

Create a ctrf.properties file in your project's src/test/resources directory to customize the CTRF report:

ctrf.report.path=build/test-results/test/ctrf-report.json
ctrf.max.message.length=300

junit.version=5.11.3

ctrf.report.name=My Report
ctrf.app.name=My Application
ctrf.app.version=1.0.0
ctrf.test.environment=staging

ctrf.build.name=feature-branch
ctrf.build.number=123
ctrf.build.url=http://ci.example.com/build/123
ctrf.repository.name=my-repo
ctrf.repository.url=http://github.com/my-repo
ctrf.commit=9aba36cedaab8d9404eebedeba3739c55af83a01
ctrf.branch.name=main

ctrf.os.platform=Linux
ctrf.os.release=5.4.0-42-generic
ctrf.os.version=Ubuntu 20.04
