FEAT: Run Tests Only for Changed Files on Specific Branches

[7alip]

Description:

Implement a mechanism to run tests only for changed/updated files if the branch name starts with test/ or /onboarding.

Steps to Implement:

• Identify Changed Files: Use Git to list the changed files.
• Filter Test Files: Extract test files from the list of changed files.
• Run Tests: Use Playwright to run tests for the filtered files.
• CI/CD Configuration: Configure the CI/CD pipeline to detect branches and execute the tests conditionally.

Suggestions:

• Use a script to automate the process of detecting changed files and running tests.
• Integrate the script into your CI/CD pipeline to ensure tests are only run for relevant branches.

1. Run Tests Only for Changed/Updated Files Using Playwright

You can achieve this by using a combination of Playwright and Git commands. Here's a general approach:

• Step 1: Identify the changed files using Git.

  git diff --name-only HEAD~1

• Step 2: Filter the test files from the list of changed files.

• Step 3: Run Playwright tests for those files.

  const { execSync } = require('child_process');
  const { test, expect } = require('@playwright/test');
  
  const changedFiles = execSync('git diff --name-only HEAD~1').toString().split('\n');
  const testFiles = changedFiles.filter(file => file.includes('.spec.ts'));
  
  testFiles.forEach(file => {
  test(file, async ({ page }) => {
    // Your test logic here
  });
  });

2. Detect Branches Starting with test/ or /onboarding in the CI/CD Pipeline

You can configure your CI/CD pipeline (e.g., GitHub Actions) to check the branch name and run the tests accordingly.

• GitHub Actions Configuration:

  name: Run Tests
  
  on:
  push:
    branches:
      - 'test/*'
      - '/onboarding/*'
  
  jobs:
  build:
    runs-on: ubuntu-latest
  
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
  
      - name: Run tests
        run: |
          git diff --name-only HEAD~1 > changed_files.txt
          changed_files=$(cat changed_files.txt | grep '.spec.ts')
          if [ -n "$changed_files" ]; then
            npx playwright test $changed_files
          else
            echo "No test files changed"
          fi

1. Identify Changed Files: Use Git commands to list the changed files.
2. Filter Test Files: Extract the test files from the list of changed files.
3. Run Tests Conditionally: Configure the CI/CD pipeline to run the tests based on branch names.
