All dmd compiler switches are documented on this page: 
[dlang.org/dmd](https://dlang.org/dmd). This one specifically, 
here: 
[dlang.org/dmd#switch-checkaction](https://dlang.org/dmd#switch-checkaction). However, I agree that the documentation doesn't provide sufficient information and that it should also be linked from the [spec/unittest](https://dlang.org/spec/unittest) page.

Right now, probably the best documentation is on the dmd v2.085 
changelog page, when it was first introduced: 
[dlang.org/changelog/2.085.0#assert](https://dlang.org/changelog/2.085.0#assert).
