ioutil has been deprecated since go 1.16, this fixes all of the
deprecated functions we are using:
ioutil.ReadFile -> os.ReadFile
ioutil.ReadAll -> io.ReadAll
ioutil.WriteFile -> os.WriteFile
ioutil.TempFile -> os.CreateTemp
ioutil.TempDir -> os.MkdirTemp
All of the above are a simple name change, the function arguments and
results are exactly the same as before.
ioutil.ReadDir -> os.ReadDir
now returns a os.DirEntry but the IsDir and Name functions work the
same. The difference is that the FileInfo must be retrieved with the
Info() function which can also return an error.
These were identified by running:
golangci-lint run --build-tags=integration ./...
Yeah, we have TestRoute. It has one issue though: It doesn't have support
for passing a custom context. One option is to extend the method with yet
argument but since it already has 9 (!!!), this seems like a huge mess.
Therefore, I decided to invent a new small library for writing API tests.
It uses structs heavily which means that adding features to it doesn't
mean changing 100 lines of code (like adding another arg to TestRoute does).
I hope that we can start using this library more in our tests as it was
designed to be very flexible and powerfule.
