Common (Android/iOS/Window Phone/WEB)

Charles web debugging proxy

During app testing we use Charles proxy server which allows to monitor http requests/responses, http headers (which contain cookies and caching information) and allows us to emulate our own test requests/responses to/from server, so additional rare cases could be emulated.

Key Benefits:

  • SSL Proxying – view SSL requests and responses
  • Monitor http/https requests/responses (Android/iOS/Windows Phone/PC/Mac)

DDMS, Xcode Console and Charles tools allow to reveal logs/requests/pesponses which might contain security data (logins and passwords). Using them while testing Android/iOS will enable access to app security status. Lucky Patcher is a tool  for Android apps and allows us to modify apps permissions, backups and restore them etc.
