About prowler-test-ui

prowler-test-ui is a skill for writing Prowler UI end-to-end tests with project-specific Playwright conventions. It emphasizes keeping tests and Markdown documentation in sync, and exploring the live page with MCP tools before writing tests.

Key features

  1. 01Defines UI test directory structure
  2. 02Requires synchronized tests and documentation
  3. 03Explores pages before writing tests
  4. 04Sets wait and navigation verification rules
  5. 05Specifies test tags and commands

Use cases

  1. 01Add end-to-end tests for Prowler pages
  2. 02Update case documentation when tests change
  3. 03Build stable tests from actual page structure

MCP support

It prescribes using Playwright MCP tools before creating tests: navigate to the target page, inspect a snapshot, and interact with elements to verify the actual structure and selectors.

Install

From the project README

Generic Patterns: For base Playwright patterns (Page Object Model, selectors, helpers), see the playwright skill. This skill covers Prowler-specific conventions only.

Prowler UI Test Structure

ui/tests/
├── base-page.ts              # Prowler-specific base page
├── helpers.ts                # Prowler test utilities
└── {page-name}/
    ├── {page-name}-page.ts   # Page Object Model
    ├── {page-name}.spec.ts   # ALL tests (single file per feature)
    └── {page-name}.md        # Test documentation (MANDATORY - sync with spec.ts)

MANDATORY Checklist (Create or Modify Tests)

⚠️ ALWAYS verify BEFORE completing any E2E task:

When CREATING new tests
  • {page-name}-page.ts - Page Object created/updated
  • {page-name}.spec.ts - Tests added with correct tags (@TEST-ID)
  • {page-name}.md - Documentation created with ALL test cases
  • Test IDs in .md match tags in .spec.ts
When MODIFYING existing tests
  • {page-name}.md MUST be updated if:
    • Test cases were added/removed
    • Test flow changed (steps)
    • Preconditions or expected results changed
    • Tags or priorities changed
  • Test IDs synchronized between .md and .spec.ts
Quick validation
# Verify .md exists for each test folder
ls ui/tests/{feature}/{feature}.md

# Verify test IDs match
grep -o "@[A-Z]*-E2E-[0-9]*" ui/tests/{feature}/{feature}.spec.ts | sort -u
grep -o "\`[A-Z]*-E2E-[0-9]*\`" ui/tests/{feature}/{feature}.md | sort -u

Important

❌ An E2E change is NOT considered complete without updating the corresponding .md file.


MCP Workflow - CRITICAL

⚠️ MANDATORY: If Playwright MCP tools are available, ALWAYS use them BEFORE creating tests.

  1. Navigate to target page
  2. Take snapshot to see actual DOM structure
  3. Interact with forms/elements to verify real flow
  4. Document actual selectors from snapshots
  5. Only then write test code

Why: Prevents tests based on assumptions. Real exploration = stable tests.


Wait Strategies (CRITICAL)

⚠️ NEVER use networkidle - it causes flaky tests!

StrategyUse Case
❌ networkidleNEVER - flaky with polling/WebSockets
⚠️ loadOnly when absolutely necessary
✅ expect(element).toBeVisible()PREFERRED - wait for specific UI state
✅ page.waitForURL()Wait for navigation
✅ pageObject.verifyPageLoaded()BEST - encapsulated verification

GOOD:

await homePage.verifyPageLoaded();
await expect(page).toHaveURL("/dashboard");
await expect(page.getByRole("heading", { name: "Overview" })).toBeVisible();

BAD:

await page.waitForLoadState("networkidle"); // ❌ FLAKY
await page.waitForTimeout(2000);            // ❌ ARBITRARY WAIT

Prowler Base Page

import { Page, Locator, expect } from "@playwright/test";

export class BasePage {
  constructor(protected page: Page) {}

  async goto(path: string): Promise<void> {
    await this.page.goto(path);
    // Child classes should override verifyPageLoaded() to wait for specific elements
  }

  // Override in child classes to wait for page-specific elements
  async verifyPageLoaded(): Promise<void> {
    await expect(this.page.locator("main")).toBeVisible();
  }

  // Prowler-specific: notification handling
  async waitForNotification(): Promise<Locator> {
    const notification = this.page.locator('[role="status"]');
    await notification.waitFor({ state: "visible" });
    return notification;
  }

  async verifyNotificationMessage(message: string): Promise<void> {
    const notification = await this.waitForNotification();
    await expect(notification).toContainText(message);
  }
}

Page Navigation Verification Pattern

⚠️ URL assertions belong in Page Objects, NOT in tests!

When verifying redirects or page navigation, create dedicated methods in the target Page Object:

// ✅ GOOD - In SignInPage
async verifyOnSignInPage(): Promise<void> {
  await expect(this.page).toHaveURL(/\/sign-in/);
  await expect(this.pageTitle).toBeVisible();
}

// ✅ GOOD - In test
await homePage.goto();  // Try to access protected route
await signInPage.verifyOnSignInPage();  // Verify redirect

// ❌ BAD - Direct assertions in test
await homePage.goto();
await expect(page).toHaveURL(/\/sign-in/);  // Should be in Page Object
await expect(page.getByText("Sign in")).toBeVisible();

Naming convention: verifyOn{PageName}Page() for redirect verification methods.


Prowler-Specific Pages

Providers Page
import { BasePage } from "../base-page";

export class ProvidersPage extends BasePage {
  readonly addButton = this.page.getByRole("button", { name: "Add Provider" });
  readonly providerTable = this.page.getByRole("table");

  async goto(): Promise<void> {
    await super.goto("/providers");
  }

  async addProvider(type: string, alias: string): Promise<void> {
    await this.addButton.click();
    await this.page.getByLabel("Provider Type").selectOption(type);
    await this.page.getByLabel("Alias").fill(alias);
    await this.page.getByRole("button", { name: "Create" }).click();
  }
}
Scans Page
export class ScansPage extends BasePage {
  readonly newScanButton = this.page.getByRole("button", { name: "New Scan" });
  readonly scanTable = this.page.getByRole("table");

  async goto(): Promise<void> {
    await super.goto("/scans");
  }

  async startScan(providerAlias: string): Promise<void> {
    await this.newScanButton.click();
    await this.page.getByRole("combobox", { name: "Provider" }).click();
    await this.page.getByRole("option", { name: providerAlias }).click();
    await this.page.getByRole("button", { name: "Start Scan" }).click();
  }
}
