I recall an issue that started with windows 8 and UEFI where the bootloader would get installed on any HDD instead of the SSD where the operating system would live.
DeprecatedCompatV2
I've worked in both android and spring boot and rewriting your security to use a filter chain is nothing* compared to the shenanigans google likes to pull. Keeping up with the deprecations and imaginary "best practices" is half the job. It's like someone combined the worst parts of react with the worst Java timeline and forced people to write inscutable spaghetti that's completely impractical/impossible to test.
*there are valid criticisms of spring security, but I think this particular change improved things, even if it felt pointless
I mean unit tests. I work on Spring Boot apps where there are distinct layers (controller -> service -> persistence), and you generally inject mocks into your object to isolate tests to the specific code you want under test. One benefit of this approach is that it's pretty easy to get 90% coverage.
How do you write tests?
Do you have any range issues? Forget to charge it?
I thought this as well.
