• Risk Analysis: The test plan's risk assessment must be updated to reflect any new risks introduced by the changes.

Automated testing frameworks and continuous integration systems may need to be adjusted to incorporate these changes. For example:

// Before change request
test('verify login', async () => {
  await page.type('#username', 'user1');
  await page.type('#password', 'pass1');
  await page.click('#login-button');
  expect(await page.find('.welcome-message').textContent).toBe('Welcome, user1!');
});

// After change request
test('verify login with OTP', async () => {
  await page.type('#username', 'user2');
  await page.type('#password', 'pass2');
  await page.click('#login-button');
  // New step for OTP
  await page.type('#otp', '123456');
  await page.click('#otp-submit');
  expect(await page.find('.welcome-message').textContent).toBe('Welcome, user2!');
});

Adapting to change requests is a dynamic process that requires test automation engineers to be flexible and responsive to ensure the test plan remains effective and relevant.

Testers should adapt their strategies to accommodate change requests by:
