Some popular user-agent strings can be found onhttps://developers.google.com/chrome/mobile/docs/user-agent.
This means when testing websites it’s important to consider whether there is a need to test on more than one device. Have the developers coded for more than one device? Is the behaviour different depending on whether the website is accessed from a desktop or an iPhone, for example? Is there a need to test that the right page is displayed on the right devices in the correct manner? Is the information truncated? Is it readable or too busy?
When testing websites and web applications, I like to consider not only whether functionality works on the various “user agents” but also how reliable it is, whether it crashes all the time or not at all or hangs often, whether it’s fairly robust, easy to use (especially navigating on smaller mobile devices), easy to read, fast enough, and whether it plays nicely with other applications on my device or PC. Of course, whether these characteristics are in scope or out of scope for testing on a particular project needs to be decided but these should at the very least be considered. What else do you think about when testing websites on different end user screens?
