The thing you check is that yaml2obj does not exit with code 0 and that the error message is as expected. See e.g. https://github.com/llvm/llvm-project/blob/4700e6b41471f8f5244c3835abdca7bb7eb5950b/llvm/test/tools/yaml2obj/ELF/section-headers.yaml#L58 for an example test case that checks for invalid YAML.
