While testing mobile applications and games a tester often comes across such a term as «a log».
Logs or a log file (log file) is a text-format file in which you can find the entire history of users actions in the application and the application's response to them in the chronological order.
The ability to get logs from a device is extremely important for a mobile application tester since a crash log file is, in most cases, a mandatory element to fill in a bug-report related to an application crash.
On iOS, there are two types of logs: console logs and crash logs. Console logs are displayed in the console log history and are records of some system events that are updated in realtime.
A crash log is a log file that is created after an emergency shutdown of the application (Crash). The crash log file has the resolution .crash or .ips. The crash log contains information from the moment the application was launched until the emergency termination of the application.
