Post #3760654

Project #RocketLang update: While working towards my current goal of having a unit-testing library in #Rocket, I came across a few bugs: 1. `string_1 + string_2` actually didn't work when one or both of the strings where empty. Fixed and added test cases. 2. `os.scandir(path)` actually wasn't working properly. Most of my test cases used mocking, but the function errored out when run without mocks. The test cases without mocking didn't properly check the results. Now I implemented a proper testcase that creates a temporary directory, puts some files there and checks for those. The `os.scandir()` test case above actually turned out to be a bit flaky: It worked locally, but failed in my CI/CD pipeline. The reason was that `os.scandir()` returned the files in a different order on the CI/CD server. So I tried sorting them by name which ... requires supporting ``, and `>=` for strings. So I implemented that, too (lexicographic sorting). And `ByteString` got a new method: `ends_with`. #Programming
