nit: Typically namespace statements have a blank line before and after them. The
only exception I've used is for class forward definitions (e.g. namespace base {
/n class foo; /n class bar; /n }). However, I have no strong opinion on this is
a header file.

 bool ShouldAbortAudioTest(bool requirements_satisfied,
                           const char* requirements_expression,
                           bool* should_fail);
