KeyError: 'testsuites' when using --junit-xml options with ctest output
## Quick Information - Ubuntu 18.04 - cmake 3.21.3 - badges-gitlab 0.8.1 ## What Happened? CMake 3.21 recently introduced the `--output-junit` option for generating a junit xml file with ctest. This is especially useful for continuous integration with gitlab. When calling `badges-gitlab` on this xml, I get the following error: ``` Traceback (most recent call last): File "/usr/local/bin/badges-gitlab", line 11, in <module> sys.exit(main()) File "/usr/local/lib/python3.9/dist-packages/badges_gitlab/cli.py", line 59, in main create_badges_test(args.path, args.junit) File "/usr/local/lib/python3.9/dist-packages/badges_gitlab/badges_test.py", line 86, in create_badges_test testsuites = content['testsuites']['testsuite'] KeyError: 'testsuites' ``` ## Explanation This error occurs because junit xml file produced by ctest does not contain a `<testsuites>` node (see attached example). ## Steps to reproduce Download attached `notestsuites.xml` file and execute: `badges-gitlab --junit-xml notestsuites.xml` [notestsuites.xml](/uploads/151e6794973216e7262442024790eadf/notestsuites.xml) ## Priority/Severity - [x] High (anything that impacts the normal user flow or blocks app usage)
