We briefly touched on tester jokes during a recent This Week in Testing. 
It’s good to laugh and smile at ourselves so how about we share some tester jokes here?
Keep it light, and remember, this isn’t a thread out to offend people. It’s just for fun – a smile and smirk at what us testers, QA and quality engineering professionals bring to the table.
I’ll start. And proud to not use GPT to “cheat”. Here’s one off the bat …
“Why did the tester cross the road?”
“I don’t know, why did the tester cross the road?”
“Because the road was a few pixels out from the requirements and the tester was frustrated that having tried a green circle and yellow triangle in previous attempts to highlight the issue, a big red cross on the screenshot of the road was the one thing that brought attention to a curious developer.”
Hey @simon_tomes on this topic I actually made a video.
You can use this API to get programming jokes
Could be just me but I like this part better, having the subtle questioning from the other person, as should a tester be doing.
How many testers does it take to change a light bulb?
None.
They can only tell you that room is dark:)
In my mother language the word “file” is “fil”.
“Fil” has also 2+ meanings, one is computer document, another is a kind of youghurt people used to buy for lunch in the cafeteria in a place I worked at.
So if someone left the table eg to fetch something extra, someone was bound to take the yoghurt package away and hide it. And when the person came back and confused looked around, the thief would go “error 21”. Guess what that error was.
Pretty nerdy, right?
I took testing very seriously and could never joke about it, to the point that I get offended by almost any joke about testing.
The testing profession is already ‘a joke’ for many testers and others influencing it.
Could be that I haven’t heard of any good jokes though…
Murphy’s laws of Software Testing:
Bugs can easily be created. They cannot however, be easily destroyed. But they can easily get transferred from one platform to another.
There is no such thing as a bug free application. But yes, bugs do come free with every application. 
Bugs do not get reproduced when you demo them to the developer / project manager.
But will magically reappear from nowhere when you demo your product to the client / customer.
Your most bug-free product version will reside in your developer’s local machine / session. Bugs never happen there.
The more the number of developers working on the product, the more bugs there will be to find. Too many cooks spoil the broth.
Bugs which have been deemed fixed and closed suddenly reoccur in Production.
No matter how extensive your test coverage is, you will always miss / overlook one crucial aspect of the product, and that’s where the show stopper will occur.
No matter how many critical bugs you find, you will be pilloried for the one bug you failed to detect.
The PM and delivery manager will always consider the testing team as dead weight.
The bug which takes the maximum amount of time to reproduce will always take the least amount of time to fix.
The bug which causes the maximum amount of damage always requires the smallest of fixes.
Customers / End users usually find more bugs than your testers’ do.
Bugs will never be apparent if you keep looking for them, but when you are not, they will pop up from every nook and corner of the application and will hit you in the face.
Automation might get things done quicker, but the amount of time it takes to prepare, script and run the tests will make you think of running the tests manually.
The most critical and time consuming bug for the developers to fix will always occur at the fag end of the testing cycle or when the product is ready to ship.
The Developers will fix the build and get it ready for testing at the fag end of the day, just when you are about to leave office.
And that build happens to be a critical release which just needs to be tested ASAP.
Most critical issues will always occur when most of your team is on vacation.
You will spend a huge amount of time and energy in detecting a bug only to find that it now not reproduced.
Even if you do reproduce the goddamn bug and file it, it inadvertently turns up not to be in scope.
Even if it is, someone else would have already filed it a long time back.
Only thirty percent of your effort is spent in detecting bugs. The remaining seventy goes in convincing developers and project managers that it is actually a bug.
The product / feature for which you have detected the maximum number of bugs will most certainly be De-scoped.
Feel free to add to the list !!
In the style of ‘doctor doctor’ jokes:
“Tester tester, I’ve been trying to have a baby for years but nothing happens!”
“I’m closing this issue as ‘Can’t reproduce’”
“Tester tester, I can’t remember the alphabet past the first two letters!”
“Sounds like you’ve been doing too much AB testing”
“Tester tester, there’s a small glitch in the display of this critical life-support machine!”
“Have you tried turning it off and on again?”
Brilliant! That made me laugh out loud.
“Hi, I’d like to hear a TCP joke”
“Hi, would you like to hear a TCP joke?”
“Yes, I’d like to hear a TCP joke”
“OK, I’ll tell a TCP joke”
“OK, tell me a TCP joke”
“Are you ready to hear a TCP joke?”
“Yes, I’m ready for a TCP joke”
“I’m sorry, your connection has timed out”*
Knock, knock.
Who’s there?
Beta.
Beta who?
Beta test your patience!
Which key is the least used key on a testers keyboard?
The right shift key. We prefer Shift Left.
My favourite one is here:
Why do programmers prefer dark mode?
Because the bugs are harder to see! 
I can tell you a joke about testing, but first I have to write a joke case.
A tester, a tester and a tester walk into a first name field.
