The second test will be for the case where the API responds with an error. Each of the above permutations should lead to different test cases if we have to specify each of the parameters/arguments in the assertion on the getPingConfigs call. WebJest provides matches for function calls. A setup thats easy to test and extend using battle-hardened technologies like Express.js, Postgres and Docker Compose to run locally. The API you will create is quite simple.
