What I want is a way to say if Test_A fails then don't run Test_B because it's guaranteed to fail and that just creates noise in the output. So instinctively I'd like something like annotations for this. // @DependsOn [ "Test_A" ] func Test_B(t *testing.T) { .test stuff }

Robbie, It's hard to understand what you are doing. The header says that there is no grade and sg is not where you say it is. Why are you using a channel? Why are you limiting the size of your input by reading the entire file into memory? And so on. My best guess is that you want to do

Internal errors are one of my pet peeves about the core go libs, as you say they are inconsistent and you end up doing all sorts of string checks which are not only hackey but are very fragile too. We had a break in our code due to just this when updating to 1.8. There are very few reason why

C++ ThreadSanitizer works on arm64. So making it work for Go should be a modest amount of work. ThreadSanitizer does not work on any 32-bit platforms. It assumes that it can reserve huge continuous chunks of address space for various things. ThreadSanitizer is not dependend on underlying hardware
