Automation Testing (English)

中文版： See skill automation-testing .

Prompt: this directory's prompts/automation-testing_EN.md .

When to Use

• User mentions automation testing, automation-testing

• Need to execute this testing type or produce deliverables per Standard-version

• Trigger examples: "Generate/design/write automation test cases for the following"

Output Format Options

Markdown by default. For Excel / CSV / JSON, add at the end of your request; see output-formats.md.

How to Use

• Open the relevant file in this directory's prompts/ and copy the content below the dashed line.

• Append your requirements and context (business flow, environment, constraints, acceptance criteria).

• If you need non-Markdown output, append the request sentence from output-formats.md at the end.

Code Examples

Location: ../automation-testing/examples/selenium-pom-python/

Includes:

• Complete Page Object Model architecture

• Base page class (BasePage)

• Login page, home page objects

• 15+ test cases

• Pytest configuration and fixtures

• Auto-screenshot functionality

• HTML test reports

Quick Start:

cd examples/selenium-pom-python pip install -r requirements.txt pytest

Test Coverage:

• Login functionality (valid/invalid credentials, locked users)

• Product list display

• Shopping cart operations (add/remove items)

• Product sorting functionality

• Parameterized tests

See: examples/selenium-pom-python/README.md

2. Playwright (TypeScript)

Coming soon - Modern web automation with Playwright framework.

3. Cypress (JavaScript)

Coming soon - Frontend-focused E2E testing with Cypress.

Best Practices

Automation Test Design Principles

Test Pyramid

• Unit tests (70%): Fast, stable, low cost

• Integration tests (20%): Test module interactions

• UI tests (10%): End-to-end business workflows

Page Object Model (POM)

• Encapsulate page elements and operations in page classes

• Test cases focus only on business logic

• Improve code reuse and maintainability

Wait Strategies

• Avoid fixed waits (time.sleep)

• Use explicit waits (WebDriverWait)

• Set reasonable implicit wait times

Test Data Management

• Use configuration files for test data

• Use fixtures to provide test data

• Clean up data after tests

Test Independence

• Each test should run independently

• Don't depend on other tests' execution order

• Use setup/teardown to manage test environment

Tool Selection Guide

Tool Use Case Advantages

Selenium Web UI automation Cross-browser, multi-language support

Playwright Modern web apps Fast, stable, multi-browser

Cypress Frontend developers Easy to use, live reload, debug-friendly

Appium Mobile apps Cross-platform, native/hybrid apps

Robot Framework Keyword-driven Readable, non-technical friendly

POM Design Pattern Best Practices

✅ Good practice

class LoginPage(BasePage): # Element locators as class constants USERNAME_INPUT = (By.ID, "username")

def login(self, username, password):
    # Method returns self for method chaining
    self.enter_username(username)
    self.enter_password(password)
    self.click_login()
    return self

❌ Bad practice

class LoginPage: def login(self, username, password): # Hardcoded locators driver.find_element(By.ID, "username").send_keys(username) # Assertions in page class assert driver.find_element(By.ID, "welcome").is_displayed()

Common Pitfalls

• ❌ Automating unstable or unclear requirements first → ✅ Prioritize stable, high-value workflows for automation

• ❌ Overusing brittle UI selectors → ✅ Prefer resilient locators and shared selector conventions

• ❌ Mixing test logic with environment setup everywhere → ✅ Centralize setup/teardown and reusable fixtures

• ❌ Ignoring flaky-test tracking → ✅ Record flaky patterns and fix root causes before scaling coverage

Target Audience

• QA engineers and developers executing this testing domain in real projects

• Team leads who need structured, reproducible testing outputs

• AI users who need fast, format-ready deliverables for execution and reporting

Not Recommended For

• Pure production incident response without test scope/context

• Decisions requiring legal/compliance sign-off without expert review

• Requests lacking minimum inputs (scope, environment, expected behavior)

Critical Success Factors

• Provide clear scope, environment, and acceptance criteria before generation

• Validate generated outputs against real system constraints before execution

• Keep artifacts traceable (requirements -> test points -> defects -> decisions)

Output Templates and Parsing Scripts

• Template directory: output-templates/

• template-word.md (Word-friendly structure)

• template-excel.tsv (Excel paste-ready)

• template-xmind.md (XMind-friendly outline)

• template-json.json

• template-csv.csv

• template-markdown.md

• Parser scripts directory: scripts/

• Parse (generic): parse_output_formats.py

• Parse (per-format): parse_word.py , parse_excel.py , parse_xmind.py , parse_json.py , parse_csv.py , parse_markdown.py

• Convert (generic): convert_output_formats.py

• Convert (per-format): convert_to_word.py , convert_to_excel.py , convert_to_xmind.py , convert_to_json.py , convert_to_csv.py , convert_to_markdown.py

• Batch convert: batch_convert_templates.py (outputs into artifacts/ )
