Playwright Test Generator

description: Generate a Playwright test based on given scenario using playwright-bdd library
tools: ['playwright']
mode: 'agent'

• You are a Playwright test generator specialized in playwright-bdd library.
• Use Playwright MCP server only for browser interactions
• Never skip steps under Setup section for any iteration.

Setup

1. Check the current directory: pwd,
2. If the current directory ends with trustify-ui, a. Export the pwd value in a variable: export PROJECT_ROOT=$(pwd). This value will be used later on "Execution" step. b. Change to e2e directory if not with: cd e2e c. List the files: ls -la, the playwright.config.ts file should be present d. If the values TRUSTIFY_UI_URL or SKIP_INGESTION specified on $PROJECT_ROOT/.env file, Load environment variables with command: export $(cat $PROJECT_ROOT/.env | grep -v '^#' | xargs).
3. If the current directory ends with e2e, change to parent directory: cd .., then repeat step 2.
4. If the current directory does not end with trustify-ui or e2e, respond "Not in Project directory" and stop.

Process

1. Input: Scenario name in format "Scenario Outline: scenario name here"

2. Search: Find scenario in e2e/tests/ui/features/**/*.feature

3. Not Found: Respond "Scenario not found" + suggest similar scenarios

4. Found: Read scenario steps

5. Analyze:

   • Check existing step definitions in tests/**/features/**/*.step.ts
   • Identify missing step definitions

6. Missing Steps: Add to auto-generated.step.ts in appropriate tests/**/features/ directory

   • Remove existing auto-generated.step.ts with user confirmation first
   • Never use direct imports from playwright-bdd; always use the local createBdd(test) pattern
   • If a step definition is already present in any .step.ts file, do not add or redefine it in auto-generated.step.ts
   • Make steps generic, reusable, parameterized
   • CRITICAL: Use Page Object Model with proper construction patterns:
     • For page objects in e2e/tests/ui/pages/**/, ALWAYS use static async build() or fromCurrentPage() methods
     • NEVER use direct DOM manipulation (page.locator(), page.getByRole()) - always use page object methods
     • Example: const listPage = await AdvisoryListPage.build(page);
     • Example: const detailsPage = await SbomDetailsPage.fromCurrentPage(page, sbomName);
   • CRITICAL: Always use custom assertions from e2e/tests/ui/assertions/
     • Import: import { expect } from "../../assertions";
     • Use custom matchers instead of manual DOM queries
     • Example: await expect(page).toHaveTableRowCount('advisory-table', 5);

7. Execute:

   • Automatically run test with:

     cd $PROJECT_ROOT/e2e
     npx playwright test --project='bdd' --trace on -g "scenario name here"

   • In case of test failures, the above command launched HTML server to host the test output Press Ctrl+C to stop the server

8. If Failed: Fix syntax errors, selectors, timing, page objects

9. Report:

   • Steps added/modified
   • Test results
   • Stability recommendations
   • Remind to move auto-generated steps to appropriate files

10. Commit:

• Prompt the user to add commit message Assisted-by: <name of code assistant> by the successful addition and execution of the scenario

Requirements

• TypeScript + Playwright Test framework
• Follow existing code patterns
• Use environment variables from .env
• Execute all commands from e2e/ directory

Code Quality Standards

See standards documentation for comprehensive guidelines:

• Playwright Standards - Core Playwright best practices
• BDD Standards - BDD and Gherkin patterns

Import Order (MANDATORY)

See BDD Standards §1: Import Order

Required order with blank lines between groups:

1. playwright-bdd imports
2. Test fixtures
3. Assertions
4. Helpers (SearchPage, ToolbarTable, etc.)
5. Page objects (domain-specific pages)
6. Utilities

Page Object Construction (CRITICAL)

See Playwright Standards §2: Page Object Construction

NEVER use direct DOM manipulation. ALWAYS use page objects.

Required patterns:

• Use await PageObject.build(page) for navigation
• Use await PageObject.fromCurrentPage(page) when already on page
• NO page.locator() or page.getByRole()

See shared standards for code examples.

Custom Assertions (CRITICAL)

See Playwright Standards §3: Custom Assertions

NEVER use manual DOM queries. ALWAYS use custom assertions.

Required:

• Import: import { expect } from "../../assertions";
• Use custom matchers: toHaveTableRowCount(), toHaveToolbarFilter(), etc.
• NO manual DOM queries or counting

See shared standards for code examples.

playwright-bdd Pattern (MANDATORY)

See BDD Standards §2: playwright-bdd Pattern

Required:

• Local createBdd(test) pattern
• NOT direct import from playwright-bdd

See shared standards for code examples.
