Xamarin.UITest<\/span>\u00a0is a\u00a0<\/span>popular\u00a0<\/span>C# testing framework which works great with both native and cross-platform apps, using frameworks like Xamarin. Today I\u2019m happy to announce two updates we have made to the\u00a0<\/span>UITest<\/span>\u00a0framework, in the form of a performance boost for cloud tests and adding\u00a0<\/span>NUnit<\/span>\u00a03 support both locally and in the cloud.<\/span>\u00a0<\/span><\/p>\n

Speed Updates\u00a0<\/span>for<\/span>\u00a0<\/span>Faster\u00a0<\/span>Screenshots<\/span>\u00a0<\/span><\/h4>\n

Along with access\u00a0<\/span>to<\/span>\u00a0additional devices to run tests, an additional benefit\u00a0<\/span>to<\/span>\u00a0using\u00a0<\/span>Visual Studio\u00a0<\/span>App\u00a0<\/span>Center\u2019s<\/span>\u00a0device cloud is the ability to take screenshots during a test and see how your app\u00a0<\/span>actually runs<\/span>. This is a highly valuable secondary aspect to testing, ensuring images are render<\/span>ed<\/span>\u00a0correctly and troubleshooting visual issues that may not be reflected in a test. Taking screenshots does come with a cost however, as it takes additional time to take and process the image, causing test runs to take longer.<\/span>\u00a0<\/span><\/p>\n

 <\/p>\n

The<\/span><\/span>\u00a0performance improvements we have done include a rework of the foundation for\u00a0<\/span><\/span>Xamarin.UITest<\/span><\/span>\u00a0on Android, now taking\u00a0<\/span><\/span>screenshots\u00a0<\/span><\/span>in App\u00a0<\/span><\/span>Center<\/span><\/span>\u00a0<\/span><\/span>has never been faster. The best part is that you do not have to change any code in your tests, just update to the\u00a0<\/span><\/span>latest NuGet packages<\/span><\/span><\/a>\u00a0and everything works out of the box. To illustrate this improvement, the screenshot service has been cut from taking 6 seconds per screenshot down to 4 seconds for a whooping 32 screenshots. That is enough pictures to compile an animated gif in less time than it took for one picture before.\u00a0<\/span><\/span>How does this impact actual test\u00a0<\/span><\/span>runs<\/span><\/span>\u00a0you may ask?<\/span><\/span>\u00a0 A test suite we have\u00a0<\/span><\/span>takes<\/span><\/span>\u00a092 screenshots and would finish in roughly 17 minutes in the old pipeline. It is now down to 2 minutes and 42 seconds for the exact same test suite using the latest updates.<\/span><\/span>\u00a0With those gains, we might even encourage you to take extra screenshots.<\/span><\/span>\u00a0<\/span><\/p>\n

NUnit<\/span>\u00a03 Support<\/span>\u00a0<\/span><\/h4>\n

One of the challenges with software development is keeping dependencies up to date. It typically means additional time working on backend systems to ensure compatibility instead of working on new features. We face this on a regular basis as we strive to maintain support for the latest Android and iOS releases in our tools, which can sometimes be released with little to no notice. Since its launch, support for\u00a0<\/span>NUnit<\/span>\u00a03 with\u00a0<\/span>Xamarin.UITest<\/span>\u00a0has been a top request from customers and one we have wanted for some time. We are excited to report our latest update closes this gap. Now y<\/span>ou can update your\u00a0<\/span>NUnit<\/span>\u00a0package along with\u00a0<\/span>UITest<\/span>\u00a0to the latest versions and run tests both locally and in App\u00a0<\/span>Center<\/span>, plus have access to the updates and fixes available in<\/span>\u00a0<\/span>NUnit<\/span>\u00a0<\/span>3.<\/span>\u00a0<\/span><\/p>\n

We hope these updates help empower you to\u00a0<\/span>s<\/span>hip\u00a0<\/span>your apps\u00a0<\/span>with higher quality and confidence.\u00a0<\/span>There has never been a better time to use App\u00a0<\/span>Center<\/span>. Sign-in to check out the latest updates, or\u00a0<\/span>sign up for free<\/span><\/a>. We offer a free 30-day trial with our device cloud so go check it out. As always, we love to hear your feedback on what is working, and what you would like to see next. Reach out on twitter at @<\/span>VSAppCenter<\/span>\u00a0or share your thoughts<\/a>. We look forward to hearing from you.<\/span>\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
