Make ScreenshotOnFailureResultFormatter take screenshots before the "After" methods are executed

---

In our project, we typically start the GUI under test in our Before methods and shut it down in the After methods.

We have a continuous integration setup with ant running the Fest tests on every check-in and would like to have screenshots of the failures, however it appears Junit 4.7 doesn't run the ScreenshotOnFailureResultFormatter code until after it's run the various teardown/After methods so we end up getting a screenshot of an empty desktop, similar to what was reported in FEST-216.

I am wondering whether it would be possible to somehow take and store the screenshot before the After methods run, in combination with the custom formatter to write them into the XML and thus include links to screenshots in the final HTML-based reports.

I'm no Junit expert, but I had a poke around in the source and it appears that perhaps extending org.junit.rules.TestWatchman instead of a custom runner might be the way to go – the failed method gets calls before the After methods do.

Now that I found this, a Google search shows me you may already be aware of the issue and TestWatchman approach.

まず ScreenshotOnFailureResultFormatter を追跡し、JUnit 4.7 の teardown とどのように統合されているかを確認してから、そのライフサイクルを、言及されている org.junit.rules.TestWatchman アプローチと比較します。完了条件は、After メソッドが GUI を終了させる前に失敗時の GUI がキャプチャされ、スクリーンショットのリンクが XML および HTML レポートで引き続き利用できることです。
