Project Lead in the morning: This one story needs to be finished till 2pm for the QA department.
Me: No problem, everything is finished and there is only one test case open. It should be finished in no time.
Also me: Spends 7 hours of intensive lagacy code debugging to find out why this shit isn't working sometimes. Try to fix it, broke some other things. Retested all cases and found 3 other minor bugs. End of the day, story is still not finished.
Now: Project Lead is mad, QA guy is mad, I am mad.
Conclusion: I hate debugging legacy code and I never again trust the last open test case!!2
How to NOT write unit tests:
A colleague of mine has developed a new package of software, many of our new projects are going to use. So in his presentation of the new functionalities he also showed us that he used unit tests to cover some of his code. So i asked him to show me that all tests passes.
He: I can show you, but one test suit will fail currently.
Me: Why?? You told us, everything is finished and works fine.
He: That's right, but they will fail because I'm currently not in the customer VPN.
Me: Excuse me, WHAT??
He: Yes, I'm not in the VPN that connects me to this one customers facility in Hungary, where the counterpart of the software is runnung live.
Me: YOU WROTE UNIT TESTS THAT TEST AGAINST A RUNNING LIVE FACILITY??
He: Yes, so I can check, that the telegramms I send are right. If I get back the right acknowledgement, the telegramm structure is right and my code is working.
Me: You know, that is not the porpose of unit tests? You know, that these test should run in any environment?
He: But they are proving, that my code is working. Everytime I change something I connect to the customer and let the tests run.
Despite the help of some other developers we could not convince him that this was not good and he should remove them. So now this package is used in 2 new projects and this test suit is still failing, everytime you execute all unit tests.7
Developer vs Tester
(Spoiler alert: developer wins)
My last developent was quite big and is now in our system testing department. So last week i got every 20 minutes a call from the tester, that something did not work as expected. For about 90% of the time i looked at the testing setup or the logs and told him, that the data is wrong or he used the tool wrong. After a couple of days i got mad because of his frequent interruptions. So I decided to make a list. Every time he came to me with an "error" i checked it and made a line for "User Error" or "Programming Error". He did not liked that much, because the User Error collum startet to grow fast:
User Errors: ||||| |||
Programming Errors: |||
Now he checks his testing data and the logs 3 times before he calls me and he hardly finds any "errors" anymore.3
My day in one sentence: I found about 20 ways in which my code doesn't work as expected.
I hate these days, where you spend 80% of the time debugging and always find tiny new bugs.5
Not really a rant (?)
I started my first programming job in January this year. I went there staight after Highschool, so i had no real experience, knew only the basics of software development and my written code was quite a mess. So one of my first real tasks (after 2 months) was to write a business logic for batch handling (for a warehouse management system). I invested quite some time to develop a suitable architecture, talked with some other developers and wanted to cover the whole thing with unit tests (which really nobody at the company uses). So I spent about 3 weeks to write the whole thing, test it and improve it many times. It worked perfectly and I got pretty good feedback from the code-review.
1 month ago - the code worked perfectly and was multiple times testet (also by the client) - the client came with some totally new requirements for the batch handling. I tried to impelemt them, but soon found out, that the architecture doesn't supported them, it was not build for the required handling and would soon become a totally mess, if i tried to make it work.
So I was pretty mad, because I had to change the whole fucking thing, but I also wanted to make it better. I hab gained some experience and decided (with some help of a senior dev) to make a completely new try with a different architecture, that can be easily expanded, if needed. I build my concept, wrote and tested the whole new code in 3 days. Fucking 3 days compared to the initial 3 weeks, and it worked, better and even faster.
I was quite pissed to delete the old code, and especially that i had wasted 3 weeks for it and had to struggle with many different things. But I lerarned so much from it and also in the months between, that I was also really glad that I had the opportiunity to write it again.
This whole thing made me now realize that this is, what I really like to do and what I'm good in. I really enjoy learning new things and for me, programming is the best and easiest way to do it. Despite alle the cons and annoying side effects of it, I really found my dream job here.1
My setup at work as a juniour dev. Got a month ago a 3rd monitor (the left), because I'm working on some backend services and had to test them with a touchscreen. Now only the frontend dev and I have 3 monitors in the whole company 😁6
So I'm writing this code, that does 2 important things, that cannot be seperated. I run the code, thing1 is correctly executed, thing2 not. No fucking idea, why this happens. Execute again, same result. Debugg the wohle thing, now everything works fine.
I check the code, there are no background tasks, no paralell processing, nothing that should go wrong.
Asking a Senior developer for help, he also has no fucking idea. He tells me to try to wait one second between the two things. Looking for a delay() or wait() function in my programming language but there is none. Ok, building my own delay, writing a "do 1000 times" loop, calculate some shit in it. Execute the code, it works perfectly.
Nobody has a fucking idea, why this is happening and why this solution is working, but now the code is productive and it works fine.9
