Most QA Testers Write Test Cases WRONG – Here's How to Fix It (TL;DR)

Most QA testers write test cases that are either too vague, too redundant, or too focused on the "happy path." And honestly? That’s why bugs still slip through even when “everything passed.”

Here’s a TL;DR on how to fix your test case writing — based on real-world QA experience.

✅ 1. Focus on Behavior, Not Just Steps

Bad test cases are rigid and step-by-step.
Great ones describe the intent and expected outcome.

Bad:
Click the login button → Check if redirected.

Better:
User enters valid credentials → System redirects to dashboard.

This makes your test cases reusable, automation-friendly, and aligned with user behavior — not UI mechanics.

⚠️ 2. Cover the Edge Cases, Not Just the Happy Paths

Most testers only cover what’s expected to work.
But in the real world, users:

Enter weird data
Leave fields blank
Close modals halfway through
Interrupt flows in unexpected ways

Bugs live in the cracks. Don’t just test what should work — test what might go wrong.

🧠 3. Use Intent-Based Naming

Your test case title should describe the goal, not the module.

Weak:

Login Test
Add Item

Stronger:

Verify login fails with incorrect password
Ensure cart total updates after quantity change

Good naming helps testers, leads, and automation tools understand what the case actually does.
