This screenshot will not win the _#screenshotsaturday_ hashtag, but it took a lot of effort to achieve 🙂

Thanks to _Andrzej Kilijański_ we have a big upgrade to our automatic tests application, available as always in [tests/ subdirectory of CGE](https://github.com/castle-engine/castle-engine/tree/master/tests). Instead of using _FpcUnit_, the application can now use our own testing framework [CastleTester](https://github.com/castle-engine/castle-engine/blob/master/tests/code/tester-castle/castletester.pas) that

1. Is deliberately very compatible with _FpcUnit_ (in fact, using some of its code).

2. Tightly integrated with CGE, providing easy UI using CGE to run and display all tests results, and some extra utilities like `CreateWindowForTest`.

3. Compiles and runs with both FPC and Delphi. All our tests now pass with both compilers. We made a number of fixes to Delphi support thanks to this (FPC support was being tested and flawless since a long time). 

4. Compiles and runs for all platforms we support. E.g. you can run the testsuite on [Android](https://castle-engine.io/android), [iOS](https://castle-engine.io/ios), [Nintendo Switch](https://castle-engine.io/nintendo_switch) this way, by building the castle-tester for these platforms — just like any other CGE application.

As always, both [Jenkins](https://castle-engine.io/cloud_builds_jenkins) and [GitHub Actions](https://github.com/castle-engine/castle-engine/actions) run all these tests automatically after every push. Jenkins even runs them with both FPC and Delphi 11.
