junit-jupiter-open-telemetry-extension

Gradle plugin for gathering data of JUnit test executions via OpenTelemetry

Setup

Extension

Add the dependency to your build.gradle

dependencies {
    testImplementation 'com.dynatrace.oss.opentelemetry:junit.jupiter.exporter:${version}'
}

Make sure that the extension is loaded. This can be done in different ways.

1. Put an annotation over your test class

@ExtendWith(TracingExtension.class)
public class Test {

2. Load the extensions via parameter

-Djunit.jupiter.extensions.autodetection.enabled=true

3. Set a system property

systemProperty("junit.jupiter.extensions.autodetection.enabled", true)

Configure the Tracer

The recommended way is to use autoconfigure to do that.

implementation 'io.opentelemetry:opentelemetry-sdk-extension-autoconfigure:${version}'

Tracing

This is what a trace of a test may look like:

The extension also adds the possibility to trace dynamic and parameterized tests.
