132-java-testing-integration-testing

132-java-testing-integration-testing is a skill for Claude Code, Codex from jabrena/plinth. It costs 155 tokens per session (795 once invoked), scanned A, original, Apache-2.0.

A guide to integration testing Java services with WireMock, a tool that stands in for outside HTTP services during tests. It covers shared test setup, dynamic ports, request checking, response files, and simulated failures.

In plain words
What is it for?
Use it to test HTTP clients and outbound calls, stub responses, simulate outages or delays, verify requests, and isolate stubs between tests.
Why use it?
It lets tests exercise real client and service integration without depending on live external systems or fixed network settings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

132-java-testing-integration-testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Java Integration testing guidelines

Set up robust integration-test infrastructure for Java services using WireMock to stub outbound HTTP dependencies.

What is covered in this Skill?

  • Infrastructure topology detection: scanning imports for HttpClient, feign.*, retrofit2.*, RestTemplate
  • Abstract BaseIntegrationTest base class
  • WireMockExtension with @RegisterExtension, dynamic port allocation (dynamicPort())
  • usingFilesUnderClasspath(wiremock), @BeforeAll + System.setProperty() for coordinate propagation
  • WireMock JSON mapping files (bodyFileName referencing wiremock/files/)
  • Programmatic stub registration via WireMock DSL
  • Per-test stub isolation: register stubs inside each test method
  • Fault injection: 503 service unavailable, network latency with withFixedDelay
  • Request verification via WIREMOCK.verify
  • wiremock-standalone Maven dependency (test scope)
  • Anti-patterns: global @BeforeAll stubs, Mockito-mocked HTTP clients, hardcoded ports or URLs

Scope: The reference is organized by examples (good/bad code patterns) for each core area. Apply recommendations based on applicable examples.

Constraints

Before applying any integration test changes, ensure the project compiles. If compilation fails, stop immediately — do not proceed until resolved. After applying improvements, run full verification.

  • MANDATORY: Run ./mvnw compile or mvn compile before applying any change
  • SAFETY: If compilation fails, stop immediately and do not proceed — compilation failure is a blocking condition
  • VERIFY: Run ./mvnw clean verify or mvn clean verify after applying improvements
  • BEFORE APPLYING: Read the reference for detailed examples, good/bad patterns, and constraints

When to use this skill

  • Review Java code for integration tests
  • Apply best practices for integration tests in Java code
  • Write Java integration tests with real infrastructure boundaries
  • Improve Testcontainers integration tests for Java code
  • Review integration test setup and teardown in Java projects

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
