`generateConfigs()` function executes a nodejs [exec] that takes many
seconds to complete. As the test was not waiting for the process to
terminate, Jest was complaining with the following error message:

```
Jest did not exit one second after the test run has completed.

This usually means that there are asynchronous operations that weren't stopped in your tests. Consider running Jest with `--detectOpenHandles` to troubleshoot this issue.
```

Additionally, this test could have a false positive expectation since it
was likely to run the snapshot comparison with previously generated
plugin configurations.

By default Jest tests will timeout if they take longer than 5 seconds to
complete, since this test takes more than 10 seconds to complete on my
local machine, this test timeout configuration has been increased to 20
seconds.
