    An Introduction to Charles Proxy


    99 Minute Workshop


    Quite often we struggle to test all scenarios due to the limitation of test data especially when apps rely on third party services and testing at different territories is required. Depending on the testability of your product, it can be hard to check all corner cases if the production back-end must be used and cannot be tricked. With a proxy, you can change what will be displayed.
    Charles Proxy is known as Man-In-The-Middle and is loaded with features. Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables us to view the HTTP and SSL / HTTPS traffic between their machine and the Internet. Charles not only allows us to learn more about how our app functions the way it does, but it also opens our eyes to an entirely new array of testing possibilities to explore. Charles makes it easy to see what is happening, so you can quickly diagnose and fix problems. Charles can help to identify the cause of the bug that relates to your app making/receiving network calls/responses.

    Charles makes debugging quick, reliable, and advanced, saving you time and frustration!

    By the end of this workshop, you will be able to use Charles Proxy like a Pro! What data is being sent / received by your app. How to use various features like - rewrite, throttling, breakpoints and much more! 


    • Understand what Charles Proxy is and how to configure it
    • Monitor, examine, and modify HTTP requests and responses
    • Assess app / website behaviour by simulating network throttling conditions.
    • Investigate issues by adding a breakpoint and manipulate the data being sent to the app
