* Combine tests in bad_webserver.go into a table No functional change intended. Signed-off-by: Maya Rashish <mrashish@redhat.com> * Use a QCOW2 image for testing badserver. This has the benefit of going through qemu-img for conversion, which can introduce more bugs. Signed-off-by: Maya Rashish <mrashish@redhat.com> * Don't pass URLs to qemu-img if Accept-Ranges header isn't bytes. Adapt unit tests so they don't also test this feature. Add a handler to bad-webserver to do a very plain HTTP response using a downloaded file from cdi-file-host. This one doesn't come with builtin support for range requests. Use this handler to test that CDI can still import images needing conversion. Signed-off-by: Maya Rashish <mrashish@redhat.com> * Invert polarity and test for "none". It's highly unlikely that a value other than bytes becomes a valid choice, but let's not rule that out. Signed-off-by: Maya Rashish <mrashish@redhat.com>
