Flutter: Golden Tests 👩🔬
Details
It's been a long time since the last Mobile Maultaschen event. This time Lucas Goldner wants to introduce you to the topic of Flutter: Golden Tests 🙌
Golden testing is a method of testing the appearance of widgets using screenshot comparisons.
It starts with 2 phases:
- Generating the sample image to compare.
- Comparing the rendered screen/widget with the sample image.
The simple idea prevents regressions in your UI code. For example, when you change a piece of code in a widget, the tests would fail if the change was visible on the screen.
Mobile Maultaschen is the mobile community of Stuttgart. We meet once a month and talk about anything in mobile app development, while eating delicious Maultaschen 🥟 and enjoying cold drinks 🍻!
