My app crashes while offline, will I get the report?


TestFairy keeps crashes on disk if it can't send them immediately. The next time the app runs, TestFairy will send out the saved crash reports and attach them to the appropriate sessions.

Will crashes be caught even after session stopped recording?


Session max-duration controls how much of the session will be recorded. Many developer won't be interested in video recording beyond the first 10 minutes. Crashes are caught regardless the max-duration limit.

In cases when the crash happened beyond the max-duration limit, the report will be attached to the session that was recorded.

What is an APK?

APK stands for Android PacKage. Simply put, it's a .zip file with a different extension and it contains all the files of the app. Compilation process results with an APK, and this can be installed on physical Android devices or emulators.

The .APK file contains many files, these can be viewed with an archiver such as WinZIP, WinRAR or The Unarchiver.

What is "instrumentation" ?

Instrumentation is process where code is added into an existing program (or app) in order to monitor, trace, benchmark and debug.

TestFairy uses instrumentation in Android to provide the app developer with a wide range of monitoring capabilities without the need to write a single line of code.

This procedure is done in real-time during an upload of an APK file. During the process, TestFairy will add instructions to monitor calls to (for example) startActivity, GPS location updates, audio record buffer callbacks and others. Each can be enabled and disabled by the developer when uploading a build, using the checkboxes customizations.

Where is the keyboard in the captured video?

TestFairy captures the screen display generated by your app. In Android, the keyboard belongs to another process, and is rendered onto the screen using a system service.

This means that TestFairy (nor your app,) has access to the pixels or what is being rendered by that process. TestFairy will not be able to record another process's video display.

If your app is a keyboard service itself, you will only see the keyboard, and not the app that is using it. For the exact same reason.

Why isn't TestFairy recording any videos?

When uploading an APK via the web interface, TestFairy can automatically use instrumentation, and add our SDK to your app. This is very useful for Product and QA Managers who don't have access to the code or can change it. With instrumentation, there is no SDK to integrate. However, TestFairy cannot instrumented in cases of multidex or instant-run. For these, you will have to integrate the SDK.

Am I required to use the TestFairy SDK?

TestFairy platforms is for both distribution and for analytics. You can use both, and you can also use just one of them.

App distribution does not require integration of the TestFairy SDK and provides an easy-to-use platform for sending iOS IPA files to testers and colleagues in your enterprise. Simply upload an Ad Hoc or Enterprise signed IPA files and send e-mail invitation to the selected testers.

Analytics require integration of the SDK. This is a 2-minutes task and it involves adding just a single line of code to your project. With analytics enabled, you will able to see a video recording when your app is being used, as well as receive logs from the device, analyse usage by checkpoints or loading of view controllers and much much more. For more information, please follow the [integration manual]
