Some simple tests using Jmeter on the public api https://airportgap.dev-tester.com/docs
Thread group of 10 testing 4 different endpoints and verifying that the response code is 200, doesn't respond in longer than 5 seconds and is not bigger than 10000 bytes
The tests are integrated to Github actions and are run using https://github.com/TimJonsson/PerfAction where I added functionality to provide my own test results file. Waiting approval on my pull request in the main repository.
