10/13/2026, 1:12 PMOh, and BTW, I did a Roborazzi comparison between TestBalloon and plain JUnit 4 based on your article. I've tried to add helper code for both variants in order to understand the minimum amount of boilerplate needed in each case:
• ScreenshotTestsViaTestBalloon.kt
• ScreenshotTestsViaPlainJUnit4.kt
With larger test volumes, I also found out that TestBalloon can run Roborazzi tests up to three times as fast as plain JUnit 4. Larger test volumes also require a memory optimization due to ship with TestBalloon 1.2.0.

10/13/2026, 1:44 PMYep. The only thing where you could have relaxed things a little bit is passing parameters directly instead of using string lookup.

10/13/2026, 2:05 PMFound itThanks! So that was quite a while ago. I should probably have scrolled down the README, where it's mentioned.
Still I have matter of seconds for the whole suit.Yeah, it's not because of the performance, just better readability if you can use the parameter classes directly.
