test: Factor macOS version specific test code
The loops over the macOS13-only tests and macOS14-only tests are exactly the same, this commit refactors them so that we have a single loop. Signed-off-by: Christophe Fergeau <[email protected]>
-
This introduces a retrySSHDial and reworks the API used to connect to the VM over vsock/tcp. This will be useful in subsequent commits which will add a way to error out from the test if the vfkit process unexpectedly stopped. Signed-off-by: Christophe Fergeau <[email protected]>

test: Use select{} in retry loops
Instead of a for{} loop with a time.Sleep, this commit switches to using select{} for retry loops. This is in preparation for catching unexpected exits of the vfkit process while running the test Signed-off-by: Christophe Fergeau <[email protected]> -
test: Catch vfkit process exiting unexpectedly
This commit an a go routine which will `Wait()` for the vfkit process. When it exits, it will push the corresponding error (or nil) to a channel. The code waiting for the VM to startup can then check for errors in their select{} retry loop, and fail acccordingly. This will make debugging test failures easier, as currently if the vfkit process dies early, the test appears to be taking a very long time without any indication as to what's going on.

test: Log vfkit output to a file
This captures vfkit stdout/stderr to a file to help understand some test failures. This file is currently removed after the test ends, its path needs to be changed if one needs to look at it after. Signed-off-by: Christophe Fergeau <[email protected]>
