Test Cases That Actually Matter: Day 6 of My 30-Day QA Challenge

 

Test Cases That Actually Matter: Day 6 of My 30-Day QA Challenge"

Intro: Why Most Test Cases Fail (Even If They Pass)

When I started my QA journey, I thought writing test cases was just ticking boxes—"Does the login work?" ✅

But over time, I realized that not all test cases are created equal. The best ones don’t just check functionality. They protect user experience.
This is what Day 6 of my #30DaysofQA challenge taught me.

💡 What Makes a Test Case Powerful?

Instead of writing test cases like:

Step 1: Enter email. Step 2: Click Login. Step 3: Success message.
I asked myself:
"What could go wrong here?"

That question changed everything.

🧠 Here’s What I Now Include in Every Test Case:

  1. User Behavior Assumptions

    • Will the user forget their password?

    • What if they click “back” mid-process?

  2. Negative & Edge Cases

    • What if someone enters only spaces in the email field?

    • How does the app respond to invalid special characters?

  3. Real-Life Disruptions

    • Network drop mid-request

    • Browser crash while submitting a form

    • Double-clicking on buttons accidentally

  4. Data Variations

    • What happens if someone uploads a huge image as profile pic?

    • What if date format varies by region?

  5. Risk vs Impact Thinking
    I prioritize test cases based on which failure would hurt the user or business most.

🚨 Mistakes I’ve Made (And You Can Avoid)

  • Writing too many “happy path” cases

  • Ignoring real-world behavior (users don’t follow the script!)

  • Repeating scenarios without new value

  • Forgetting to update cases when features evolve

✅ Today’s Takeaway: Think Like a Hacker, Act Like a User

Test cases aren’t just documentation—they’re protection.
They guard against bugs, breakdowns, and bad UX.

And the best ones? They reflect empathy + curiosity.

📣 What’s Next?

Tomorrow I’m diving into [Your Day 7 Topic, e.g., API Testing, Mobile Testing, or Test Case Optimization].

No, AI Won't Steal Your Job: Why Manual Testing is More Critical Than Ever

"Manual Testing Isn't Dead. It's Your Secret Weapon for Quality." If you spend any time on tech forums or LinkedIn, you’ve heard the prophecy: “Automation and AI are coming to replace manual testers.” The story goes that in the near future, smart algorithms will handle everything, making human testers obsolete. I’m a Software QA Engineer who has been in the trenches with everything from complex fintech platforms to social media and gaming apps. And I’m here to tell you that this prediction is fundamentally wrong. Manual testing isn't dead. It's evolving. And in an age dominated by automation, its role has become more specialized and more critical than ever. Automation can check for expected outcomes, but it can't replicate the one thing that truly defines quality: the human experience. The Automation Fallacy: What a Script Can't See Test automation is a game-changer, and I rely on it every day. It's brilliant for running repetitive regression suite...
