Test Automation Strategy
<default_to_action>
When designing or improving test automation:
FOLLOW test pyramid: 70% unit, 20% integration, 10% E2E
APPLY F.I.R.S.T. principles: Fast, Isolated, Repeatable, Self-validating, Timely
USE patterns: Page Object Model, Builder pattern, Factory pattern
INTEGRATE in CI/CD: Every commit runs tests, fail fast, clear feedback
MANAGE flaky tests: Quarantine, fix, or delete - never ignore
Quick Anti-Pattern Detection:
Ice cream cone (many E2E, few unit) → Invert to pyramid
Slow tests (> 10 min suite) → Parallelize, mock external deps
Flaky tests → Fix timing, isolate data, or quarantine
Test duplication → Share fixtures, use page objects
Brittle selectors → Use data-testid, semantic locators
Critical Success Factors:
Fast feedback is the goal (< 10 min full suite)
Automation supports testing, doesn't replace judgment
Invest in test infrastructure like production code
</default_to_action>

When to Use
Building new automation framework
Improving existing test efficiency
Reducing flaky test burden
Optimizing CI/CD pipeline speed
Test Pyramid
Layer % Speed Isolation Examples Unit 70% < 1ms Complete Pure functions, logic Integration 20% < 1s Partial API, database E2E 10% < 30s None User journeys

Page Object Model
class LoginPage {
constructor (page ) {
this .page = page;
this .emailInput = '[data-testid="email"]' ;
this .passwordInput = '[data-testid="password"]' ;
this .submitButton = '[data-testid="submit"]' ;
this .errorMessage = '[data-testid="error"]' ;
}
async login (email, password ) {
await this .page .fill (this .emailInput , email);
await this .page .fill (this .passwordInput , password);
await this .page .click (this .submitButton );
}
async getError (return this .page .textContent (this .errorMessage );
}
}
test ('shows error for invalid credentials' , async ({ page }) => {
const loginPage = new LoginPage (page);
await loginPage.login ('bad@email.com' , 'wrong' );
expect (await loginPage.getError ()).toBe ('Invalid credentials' );
});

Remember Pyramid: 70% unit, 20% integration, 10% E2E. F.I.R.S.T. principles for every test. Page Object Model for E2E. Parallelize for speed. Quarantine flaky tests - never ignore them. Treat test code like production code.
With Agents: Agents generate pyramid-compliant tests, detect flaky patterns, optimize execution time, and maintain test infrastructure. Use agents to scale automation quality.
