Charles allows the tester to quickly find the source of the problem, efficiently sort through the different types of errors that come up, and duplicate various test scenarios.Ī major benefit of using Charles is that it is compatible with a majority of web and mobile browsers.Ĭharles does not require the user to reconfigure their browser settings each time they test an application, because it performs automatic configuration with most browsers. This includes requests, responses, and HTTP headers. Software applications like Charles prove to be extremely useful, and almost essential, in these cases.Ĭharles is an HTTP proxy, also known as HTTP monitor or Reverse Proxy, that allows the tester to view all of the HTTP and SSL/HTTPS traffic between their machine and the Internet. A huge setback can occur when certain features don’t respond or behave in an expected way, but typically the tester has no way of knowing what request or response was sent between the application and the Server. As any tester knows, software testing can be a rewarding yet tedious task.
