Love this, 100% accurate. QA people are amazing, protect us from ourselves in so many ways we didn’t even think of.

The programmer's answer?

We don't support that use case.

Physicist: "assuming a spherical year ..."

Based on the only comparison we have, the OP is twice the age of their sister. so the sister is now 44/2, or 22. Easy problem.

I'm working on a gameboy emulator and the amount of edge cases you have to consider feels just like this lol.

Fails to consider the case in which the 2-year-old sister is now male.

I design software, another guy builds it, then I test it. I seem to have a really good intuition for ferreting out the edgiest of edge cases and generating bugs. Pretty sure he hates my guts.

Am I an oddball in that as a developer, that QA answer is the sort of answer I give? It annoys management to no end.

Didn't even consider leap years. Smh

Real talk: I wish more orgs place a high value on QA. A good QA team is worth it's weight in gold and helps prevent a lot of stupid mistakes.

I used to have a QA job. Can confirm, this is the soup in my head. That's why I was good at testing. Also, that's not your sister. That's your trans brother, who we also love. See?

If you were 4 and now you are 44 then you might be an integer variable. If sister is also a variable, we don't know when she was allocated. She might also be an integer constant in which case she's arguably immortal.

Also misses the edge case where sister was born on a leap day

[Test]
public void Sister_IsAstronaut() 
{

import birthday;

let myAge1 = 4;
let sisterAge1 = 2;
let myAge2 = 44;

let sisterAge2 = birthday.deriveAge(myAge1, sisterAge1, myAge2);

print(sisterAge2);

Any bugs should be reported upstream. Please open a tracking issue to sync changes with eventual upstream fixes.

I'm a programmer and my answer would be more like the tester's answer.

But okay I also used to be a tester so this comment is probably invalid.

well she is half my age and that is a well known time invariant so she is 22

Really have to start with a definition of "now"

Managers when a tester does this in a planning meeting, asking for more time to write better teats: 😠

Managers when a staff level engineer does this in a post-fuckup root cause analysis meeting telling everyone what went wrong: 🤤

Managers when the tester points out it wouldn't have happened if tests for it had gotten written:

Also, we first have to define more precisely what 'being 2' means. E.g., if we just count birthdays and one of them is born on Feb 29th in a leap year, that person 'ages' with 1/4 of the speed.

That's a good tester.
In my experience coders usually make absolutely terrible testers, testing only for the most inane case, or just positive cases (ie, it does the nominal case without bursting into fire).

This may be why I hated math.
