webapp-selenium-testing

webapp-selenium-testing is a skill for Claude Code from fugazi/test-automation-skills-agents. It costs 84 tokens per session (2,450 once invoked), scanned A, original, MIT.

A guide for browser testing with Selenium WebDriver in Java projects that use Maven and JUnit 5. Selenium drives real browsers such as Chrome, Firefox and Edge to check web behaviour.

In plain words
What is it for?
Use it to create or debug browser tests, model pages, check forms and user journeys, run tests across supported browsers, and set up the Java test project.
Why use it?
It provides patterns for synchronising with pages and organising tests so browser checks are less fragile. It also helps diagnose failures with screenshots and explicit waits.

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

webapp-selenium-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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/setup-maven-project.ps1), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Web Application Testing with Selenium WebDriver

This skill provides patterns and best practices for browser-based test automation using Selenium WebDriver within a Java/Maven environment.

Activation: This skill is triggered when you need to create Selenium tests, debug browser automation, implement Page Objects, or set up Java test infrastructure.

When to Use This Skill

  • Create Selenium WebDriver tests with JUnit 5
  • Implement Page Object Model (POM) architecture
  • Handle synchronization with Explicit Waits
  • Verify UI behavior with AssertJ assertions
  • Debug failing browser tests or DOM interactions
  • Set up Maven test infrastructure for a new project
  • Capture screenshots for debugging
  • Validate complex user flows and form submissions
  • Test across multiple browsers (Chrome, Firefox, Edge)

Do NOT Use For

  • Playwright/TypeScript UI tests (use playwright-e2e-testing).
  • Driving a live browser interactively for exploration (use playwright-cli).
  • Standalone API/contract testing (use api-testing).
  • Governing a regression suite's CI tiers and sharding (use playwright-regression-testing).

Prerequisites

Component Requirement
Java JDK 11 or higher (17+ recommended)
Maven 3.6 or higher
Browser Chrome, Firefox, or Edge

Note: Selenium Manager (included in Selenium 4.6+) automatically handles browser driver binaries.


Core Patterns

Page Object Model

Separate page interaction logic from test code:

src/
├── main/java/
│   └── com/example/
│       ├── pages/          # Page Object classes
│       │   └── LoginPage.java
│       ├── components/      # Reusable UI components
│       ├── factories/       # WebDriver factory
│       ├── utils/          # Utilities
│       └── base/           # Base classes
└── test/java/
    └── com/example/
        └── tests/          # Test classes
            └── LoginTest.java

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.
