I should have extended this to say that testers should read javadocs 
output but not the actual source code.

There's a bit more they should do as well: this needs to be reflected 
back to the designers and added into the system documentation. It also 
needs to be clearly documented in the code, e.g. in Java it needs to be 
mentioned in class and/or method-level comments so that it is visible in 
javadocs output.

IOW prefer to see this sort of thing described at both the documentation 
that designers working on system changes and enhancements will read *and* 
where it should be seen and read by devs making changes to the code.
