This function is testing nothing if defaultValue = 'auto' which is the only way
you call it.

If we reject the value because we don't handle it (and I am not sure we do),
text-justify would be the default 'auto'.

To be sure that we do handle it, you need to use non-default values for the
parent element ('inherit') / the element ('initial').

I see. 
I'll try it with another value.

+    testComputedStyle("textJustify", "text-justify", "[object CSSPrimitiveValue]", defaultValue);
+    debug('');
