SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Jenkins plugin testing requires specialized test harnesses and patterns to ensure reliable plugin behavior across different Jenkins versions. This skill provides guidance on choosing the right test rules (JenkinsRule, RealJenkinsRule, JenkinsSessionRule), configuring test dependencies, and applying acceptance test harness patterns to maintain quality and stability.

Core Features & Use Cases

Provides structured patterns for config roundtrip, pipeline testing, and snippetizer testing.
Demonstrates how to integrate test utilities such as WebClient, CASC testing, Security testing, and ATH page objects in plugin tests.
Offers practical guidance for running tests with Maven and aligning dependencies via BOM, with anti-patterns to avoid.

Quick Start

Install and wire up Jenkins plugin tests using the harness and implement tests with the recommended rules to verify results by running mvn test.

FAQPage Schema

How do I write Jenkins plugin tests with the right test harness?▼

Jenkins plugin tests require specialized test harnesses like JenkinsRule, RealJenkinsRule, and JenkinsSessionRule to ensure reliable behavior. Choose the appropriate rule based on your scenario—config roundtrip, pipeline testing, or snippetizer testing—and run tests via Maven.

What is the difference between JenkinsRule and RealJenkinsRule for plugin testing?▼

JenkinsRule provides an in-process test harness for standard plugin tests, while RealJenkinsRule launches a real Jenkins instance for more realistic acceptance test harness workflows. Selecting the right rule ensures reliable plugin behavior across different Jenkins versions.

How do I set up Maven dependencies for Jenkins plugin testing?▼

Configure Maven test dependencies for Jenkins plugin testing by aligning versions via a BOM (Bill of Materials). This approach manages test utilities, CASC testing, and security testing dependencies consistently to avoid anti-patterns and maintain stability.

Can I use Configuration as Code (CASC) testing with Jenkins test harnesses?▼

Yes, CASC testing integrates with Jenkins plugin test harnesses to verify configuration roundtrip behavior. Apply specialized test rules alongside CASC, WebClient, and ATH page objects to validate plugin configuration reliability and security considerations.

What are common anti-patterns to avoid when testing Jenkins plugins?▼

Common Jenkins plugin testing anti-patterns include misaligned test dependencies, using inappropriate test rules for the scenario, and neglecting security testing. Follow structured patterns for config roundtrip, pipeline, and snippetizer testing to maintain quality and stability.
