#### Wrapping QEMU Test Execution

`runner.rb` is a [Ruby] wrapper script around `QEMU` that, for unit tests, catches the case that a
|
|
|
|
`dispatch.rb` is a [Ruby] script which first determines what kind of test is due by inspecting the
|
|
|
|
test gets stuck, e.g. in an unintentional busy loop or a crash. If `runner.rb` does not observe any
|
|
|
|
`QEMU`-command that was given to it. In case of `unit tests`, we are only interested if they all
|
|
|
|
output of the test kernel for `5 seconds`, it cancels the execution and reports a failure back to
|
|
|
|
executed successfully, which can be checked by inspecting `QEMU`'s exit code. So the script takes
|
|
|
|
`cargo`. If `QEMU` exited itself by means of `aarch64::exit_success() / aarch64::exit_failure()`,
|
|

The easy case is `QEMU` existing by itself by means of `aarch64::exit_success()` or
|
|
|
|
|
|
|
|
`aarch64::exit_failure()`. But the script can also catch the case of a test that gets stuck, e.g. in
|
|
|
|
|
|
|
|
an unintentional busy loop or a crash. If `ExitCodeTest` does not observe any output of the test
|
|
|
|
|
|
|
|
kernel for `MAX_WAIT_SECS`, it cancels the execution and marks the test as failed. Test success or
|
|
|
|
|
|
|
|
failure is finally reported back to `cargo`.

|
|
|
|
|
