hoverfly | Lightweight service virtualization/ API simulation | Mock library

Say that Java application makes requests to http://www.google.com/... and there's no way to configure the inherited library (making such requests internally), so I can not stub or replace this URL.

Please, share some best practices to create a mock like

whenCalling("http://www.google.com/some/path").withMethod("GET").thenExpectResponse("HELLO")

so a request made by any HTTP client to this URL would be redirected to the mock and replaced with this response "HELLO" in the context of current JVM process.

I tried to find a solution using WireMock, Mockito or Hoverfly, but it seems that they do something different from that. Probably I just failed to use them properly.

Could you show a simple set up from the main method like:

1. create mock
2. start mock simulation
3. make a request to the URL by an arbitrary HTTP client (not entangled with the mocking library)
4. receive mocked response
5. stop mock simulation
6. make the same request as on step 3
7. receive real response from URL

Using Hoverfly-java to mock web services in unit tests, and using HttpClient as web client, found that hoverfly proxy settings are propagated properly using useSystemProperties() however I still have TLS error: unknown certificate, I have to add certificate manually to keystore using

Looking at Hoverfly installation it describe how to install using Docker or Homebrew or Kubernetes

I don't use micro services and don't have/use Docker/Homebrew/Kubernetes

Can I still use Hoverfly or I have to install Docker/Kubernetes to execute it on windows/linux?

I'm using hoverfly in my spring boot project's unit test.

The spring boot project will grab its config (connection timeout etc.) from spring cloud config server. To test whether my timeout configs work, I write a unit test, and expect the hoverfly can return with a long delay , then my customized restTemplate can throw timeout error instead of wait. The unit test looks lilke this:
