How can you reduce risk when implementing agile development in your SDLC?
This post is part of a series on the test IO blog about real bugs that our testers have found during test cycles. In each post, we explore the details of the issue, explain its impact, and discuss what software teams can do to avoid similar problems.
While testing an entertainment news site, one of our testers found a bug during exploratory testing by attempting to switch from portrait to landscape orientation. First, the tester clicked to play a video on the site while in portrait orientation. Then, the tester rotated the smartphone from portrait to landscape orientation while the video was still playing. When the tester switched to landscape, the app crashed.
The bug was initially discovered on Apple iPhone 5s, 8.4.1. However, it ended up being reproducible on multiple devices and versions of iOS.
window.addEventListener("deviceorientation", handleOrientation, true);
In this case, the app may have crashed because it restarted when the orientation changed. Most likely it destroyed the previous session and had trouble with the restart. There could have been an issue with the processing of the width and height, when changing from portrait to landscape, with regards to the video.
The video file itself could have been corrupt, causing the entire app to crash. The tester had to tap the video more than once for playback while in portrait mode, which could have caused underlying functionality issues with the app’s controllers.
