Recently I tried making my first contribution to Ardupilot by changing some typos and grammatical errors as I am fairly new to this , but during my pull request submission phase it is showing “PR run failed” because the request failed one test case out of the 56 test cases.Any suggestions what should I do next ???
Thanks in advanced
Welcome, Its only a read-me change so its no big deal. Easiest way is to re-base and force push to trigger the tests to re-run. You could also take the chance to change the commit message to:
README: fix grammatical errors
You can also jump on the dev discord and ask someone to re-start the tests for you, that is also a great place to ask development questions.
Well… you can wait until someone fixes the flapping test - or dig in and
try to fix it 
Otherwise, generally someone with rights will poke the test to rerun it…
