Closes #82

[Copilot]

Pull request overview

Adds Android instrumentation (androidTest) coverage for the Api.post() pipeline in Wultra PowerAuth Networking, including offline tests via MockWebServer and optional real-server integration tests configured via androidTest assets.

Changes:

• Adds MockWebServer-based instrumentation tests validating request construction (headers/body/path) and response/error handling for Api.post().
• Adds real-server integration tests (skippable when config.json is absent) to exercise E2EE, signed, and token-signed endpoint flows against a PowerAuth/Enrollment/Operations backend.
• Introduces androidTest support utilities (IntegrationTestApi, endpoint definitions, config loader, activation lifecycle proxy) and documents required asset configuration.

• In this callback, fail(...) throws immediately, so latch.countDown() is never reached. That can make the test hang until the await timeout and hide the real failure. Count down the latch before calling fail, or use try/finally to guarantee countDown().

                listener = object : IApiCallResponseListener<StatusResponse> {
                    override fun onSuccess(result: StatusResponse) {
                        fail("Request should have failed with wrong PIN but succeeded")
                        latch.countDown()
                    }
