Web technology has significantly developed. Modern web applications can do a lot of things; they are interconnected between each other and provide rich user experience.
Mobile web programs are especially interesting, as one can interact with them by means of touch screen, gestures, moves of the tablet or smartphone. Besides it is possible to work with web mobile software anywhere where the device can connect to the Internet.
Unfortunately, many mobile web applications contain serious errors. Some of the errors are often overlooked during web site testing on mobile devices and mobile application testing. Quality assurance experts claim that some errors in web software are hard to detect and reproduce as they may involve many factors, and it is very easy to make a mistake while writing the code. This is especially true about mobile web applications.
Among the Most Serious Defects of Mobile Web Applications Are:
- crashing and shutting down of a web browser;
- memory leaks;
- endless loops of error mode or other conditions.
It may be hard to determine why the web browser shut down. A mobile operating system can close it because it consumes too much resource. It also can happen because an error in the browser or one of the applications operating in it.
The browser can use too much resource because too many web applications are running in it and too many operations are executing. It may also happen because one of the applications has a memory leak or other errors.
A professional software testing company advises its testers to watch carefully everything that is happening on the smartphone or tablet when the tested web program slows down. It may mean that there is a defect in the web program.
When the Tested Web Application Starts to Work Slowly, it is Necessary to Pay Attention To:
- strength of the networking signals;
- type of the utilized network;
- the battery charge level;
- other programs running on the device;
- different processes on the device, like receiving and sending messages, receiving and making calls, interference of different notifications and so on;
- user actions and moves.
Some combinations of these and other factors and conditions may cause unexpected defects. It may be very hard to repeat such defects and to determine their causes.
If a tester figures out how to repeat the error, it is much easier to figure out the root of the problem.
The Essence of a Tricky Defect Can be Determined By:
- error messages;
- special instruments that help to get crash logs or stack traces.
If all the needed information about the defects is gathered during mobile testing, desktop testing or web site testing, it is much easier for the developers to correct them.
