This is designed to test all subcommands of 'qemu-img' however so far 'commit' is not implemented.
* For 'check' subcommand test, it will 'dd' to create a file with specified size and see whether it's supported to be checked. Then convert it to be supported formats (qcow2 and raw so far) to see whether there's error after convertion. * For 'convert' subcommand test, it will convert both to 'qcow2' and 'raw' from the format specified in config file. And only check 'qcow2' after convertion. * For 'snapshot' subcommand test, it will create two snapshots and list them. Finally delete them if no errors found. * For 'info' subcommand test, it simply get output from specified image file.
