Such requirement is not obtainable realistically speaking.

E.g.

http://test.csswg.org/source/contributors/ttwf_bj/silverma/submitted/border-radius-horizontal-value-is-zero.html

This is an OK test; this is a reasonable test. Albeit there are some  
issues with the test but, as far as failing in  
non-capable-CSS3-border-radius browsers, the test is adequate,  
appropriate.

I suggest to use

Test passes if the 4 corners of the rectangle are <strong>rounded</strong>.

Test passes if the 4 corners of the rectangle are <strong>square</strong>.

I recommend to use the same introductory formulation: Test passes if  
[boolean condition].

There is a number of situations where border-radius declarations can  
not create rounded corners. Therefore, such requirement can not in all  
fairness be applied.

Eg. Border-collapsed tables, table rows in border-collapsed tables, etc.
