Tests for Exercise 1. Implemented with C# in .Net Core 3.1 using NUnit as a test framework, RestSharp for the API calls and SpecFlow for the gherkins logic.
Tests for the API are defined in the PetStore.feature gherkin file and implemented in PetStoreSteps.cs . Visual Studio's test explorer should detect it as the tests to be executed. NUnit's logs will register each step or issue found.
Here we test 4 calls to the pet API. All API call logic is stored in a class separated from the test: PetTestAPI.cs. It leaves everything more tidy.
The petstore.swagger API is rather unreliable and takes some time for a register to be updated/created/deleted. Wait some time after a test, have a coffee, then run the next test.
