I am wondering why's everyone going after testing this week 😆

Released to production last week... time to start testing this week. 😂

Just wanted to take a screenshot and it seems to be impossible outside of testing so I lookt into its implementation 🤷‍♂️😂

You can use

TestComposeWindow

🙂

val window = TestComposeWindow(width = 1024, height = 768)

window.setContent {

}

File(path).writeBytes(window.surface.makeImageSnapshot().encodeToData()!!.bytes)

Thanks @Igor Demin for this very clear example 🙏 Would be really cool if this would find its way into the test documentation and if not I will personally create a pull request for it ^^ Additional question: Can we just create an skia surface, print our components to it and take a screenshot from that? (without creating a whole window)

Very good idea, thanks 🙂 https://github.com/JetBrains/compose-jb/issues/368#issuecomment-811166809

TestComposeWindow

does exactly that. It doesn't create a whole window.

Very cool 👍 ok sorry for misinterpreting the class name I will try it asap. Thanks 😁

SwingUtilities.invokeLater

is needed because we don't properly handle

mutableStateOf

observations in other threads than Swing thread.
