Firebase simply did not behave as documented. Whole features shipped that were just wishful thinking.
It reeked of high-level management applying pressure to ship-now-no-matter-how-broken.

> Steps to reproduce:
> Step 1: Read the documentation for setting up cloud storage unit tests at: https://firebase.google.com/docs/rules/unit-tests#storage
> Step 2: Attempt to write unit tests following the examples in the documentation
The reporter describes five problems which will thwart you when you try to write code according to the official documentation.
How did these docs ship? Did nobody ever try the sample code and verify that the features worked as advertised? Did nobody write any tests to validate that the features actually worked? Are there no policies in place (e.g. "new features require tests" or perhaps code review) to prevent such mishaps?
