How to record & replay http traffic in Android and iOS apps

Starting 2022 I joined a small but ambitious startup (mobile.dev), with the goal to create much needed infrastructure for mobile development.

We analyse apps and run performance benchmarks to detect issues pre-production and in some cases we require instrumentation tests with network mocking.

My first task? Figure out if we can mock the network ourselves in order to make it easier to use our product. Creating and maintaining instrumentation tests with mocking is never easy — so we wanted to handle that responsibility on our side.

Today i’ll share a small part of my journey. In particular, how to:

• Create a realistic mock server, just by browsing an app.
• Make the app communicate with the mock server.
• Edit api responses to whatever we like

This can be useful to create ideal testing environments , with little to no manual work.
