CoTester vs Playwright MCP: Which Automation Tool is Better for QA Teams?

Image
  Scaling test automation across an enterprise team involves more than generating tests. It means keeping them stable as your application changes, ensuring the right people can contribute without creating bottlenecks, and managing the maintenance overhead that grows with every release. CoTester by TestGrid is built for that problem. Teams evaluating it also often encounter Playwright MCP, a widely adopted AI browser automation tool that overlaps in some areas but operates very differently in practice. If you’re keen to learn about Playwright MCP vs CoTester, this comparison blog post is for you. We cover both tools across various criteria that matter most for enterprise QA teams. Let’s get started.

MFA Testing Guide: How to Design Secure Multi-Factor Authentication Test Cases

Image
  Before you answer that, let’s take a simple scenario: you enter a password, receive an OTP via SMS or authenticator app, complete verification, and gain access. That confirms the happy path works, but it says nothing about how your multi-factor authentication holds up against invalid inputs, expired tokens, brute-force attempts, MFA bypass techniques, and session edge cases. These are the exact conditions where authentication failures occur in production. Testing MFA security means going beyond the happy path. Whether you’re a QA engineer validating authentication flows or a  security tester  probing for vulnerabilities, structured MFA testing is how you confirm that access control works exactly as designed, not just under ideal conditions, but under the ones that actually matter. In this guide, you’ll learn what that is, why it’s important, which MFA test scenarios to cover, and how to create test cases that corroborate multi-factor authentication flows effectively. Wh...
