NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

Trial
In the past, when discussing component testing, we’ve generally advised against browser-based tools. They were difficult to set up, slow to run and often flaky. This has improved significantly. Today, browser-based component testing, using tools such as Playwright, is a viable and often preferable approach. Running tests in a real browser provides more consistency, as the test matches the environment where the code actually executes. The performance hit is now small enough that the trade-off is worthwhile. Flakiness has also decreased, and we’re seeing more value than from emulated environments such as jsdom.
