Read on to learn how we used to deal with large project testing and which awesome new possibilities are available now!ĭuring development of the massive Unity 5 release, and the extensive changes it entailed, we frequently ran into issues with importing and building projects. For Unity 5 we wanted a cleaner API, which in some cases meant we had to break backwards compatibility. Often, when importing an older project in Unity 5, we had to fix scripts manually. We were also hitting major bugs and regressions in graphics, physics and performance related areas. Our testers do a very good job at making sure that projects import, build and run properly in every new build on all our supported platforms, but since we are constrained by time we usually used small projects (like AngryBots or Nightmares) to run these tests. These projects don’t cover many of Unity’s features – any of which might break in a new version – and they are nowhere close to the size and complexity of some of the projects developed by our users. We were fortunate enough to have a few major studios share the full project folders for some of their completed games with us (for example, Republique) and we started manually importing and building these games on every new build during the beta and release candidate phases of development.
We found and fixed many issues before any of our users would have been affected by them, but it was a tedious and time-consuming task. Install the new Unity build on Windows and OSX.This is how the testing process worked back then: Fix any scripts or other issues and build the game for Mac and Windows Standalone.Wait a long time and check back from time to time to see if it has finished (often the Script Updater dialog would require a confirmation prompt which meant even more waiting).
Repeat from steps 2-7 for all the other large projects we had (7 in total).Wait a long time again and check to see when it is finished. This was usually done by one person and it could take a few days. We quickly started discussing how we could automate some of this.
