Welcome to the eternal rivalry of the software world: Tester vs Developer. It’s a tale as old as time, or at least as old as the first bug labeled “works on my machine.”

Round 1: Bug Reporting vs Bug Denial 

The tester opens a ticket:

“Login crashes when password contains emoji + Sanskrit + 32 spaces.”

The developer responds:

“Hmm. I can’t reproduce this. Did you try turning it off and on again?”

The tester attaches:

• Video proof

• Screenshot

• System logs

• A legal affidavit

• A blood sample

Still, the developer insists, “Strange. Works fine here.”

This continues until the demo call, where the bug magically appears in front of management. Developer suddenly becomes religious.

Round 2: Communication Styles

Tester emails:

“This flow crashes when user clicks rapidly 8 times while device is in airplane mode at 2% battery.”

Developer reply:

“Why would anyone do that?”

Because QA stands for “Questioning All logic.”

Round 3: Bug Severity Negotiation

• Tester: “This is a Critical issue. It breaks the app.”

• Developer: “Can we mark it as Low Priority? Only one guy in Lithuania might ever face it.”

• PM: panics in sprint grooming.

Eventually it’s marked as “Won’t Fix” and buried deeper than ancient scrolls.

The Passive-Aggressive Bug Reopen

Developer marks bug as “Fixed.”
Tester reopens it with the dreaded comment:

“Still reproducible. Added video evidence + popcorn for your viewing pleasure.”

Developer silently screams into void, rewrites half the module, and considers becoming a barista.

The Final Boss: Regression Testing

Developer fixes a bug.
Tester: “Nice fix. But now the checkout, settings, and search are broken.”

Developer: “What?! That’s not related!”
Tester: “Everything is related. I don’t make the rules. I just break your code.”

🪄Wisdom:

The tester vs developer dynamic is not a war—it’s a high-stakes tango. One builds castles, the other throws rocks until it becomes a fortress. In the end, both just want one thing: to blame the PM.
