Chrome DevTools (E2E testing):
Tests must produce the same result every time.
Tests should not depend on each other or shared state.
Test names should describe the behavior being tested.
test("user registration sends welcome email", async () => {
// Arrange
const emailService = new MockEmailService();
const userService = new UserService(emailService);
// Act
await userService.register("test@example.com");
// Assert
expect(emailService.sentEmails).toContainEqual({
to: "test@example.com",
subject: "Welcome!"
});
});
// Use Chrome DevTools MCP for browser automation
// - Navigate to pages
// - Fill forms and click buttons
// - Capture screenshots for visual regression
// - Run Lighthouse accessibility audits
// - Check console for errors
# Run tests
npm test
pytest
go test ./...
# With coverage
npm test -- --coverage
pytest --cov=src
go test -cover ./...
