Mocking Network Requests

[itkhanz]

Problem or motivation

Is there an existing feature already in Mobilewright which enables intercepting and mocking HTTP/HTTPS network traffic from mobile apps? It would be great to have this feature buil-in so it allows a broader testing of mobile apps which typically require mocked responses to test different scenarios.
Playwright already provides this feature for web traffic, so to have this possibility in Mobilewright for mobile apps as well would be really great.

Proposed solution

This will probably require integrating some kind of mock server and mitmproxy to intercept and mock network traffic, by having the ability to install CA certificate, setup proxy, and change request/response.

Target platform

Both

Alternatives considered

No response

Additional context

Hey @itkhanz . Thanks for the suggestion. Yes, it's coming up. We have managed to create this on mobile devices as well. You'll be able to mock responses, inspect req/resp, drop requests, shape network traffic (slow it down), and create .har files on the fly (or part of trace).

The only limitation is that your app must be debuggable (debuggable true for android, or get-task-allow for iOS). Beyond that, we can inspect and modify any request/response without ssl issues.

Shall I keep you posted when we have this out? Would love to see how you'd use it.

Yes please, I would love to try out this feature. Our test apps are debuggable so it should work straightaway.

@gmegidish If it is a rooted android device, can we also do it for an app that is not debuggable?
