When you need to test an application that consumes a web API, you basically have two options:
- Use Testcontainers to start a container that will run the web API which your application will consume.
- Mock a Web Server to emulate the web API which your application will consume.
Many times, starting a container for that is not an option. For instance: you might not have a container environment available, or you just don’t have the artifacts to create that container (it might be a 3rd part API), or it is hard to emulate the needed behavior with containers.
