One simply can't test all lenses on all available cameras - ever available.
You can countercheck on DxO. They have a wider range of bodies to choose from. It's not an in-depth testing with sample pictures like here, but contrary to PZ they are asking money for their software so they do have a different financial background.
So, if you see a lens here tested with 50D, you can look if DxO did also test it on 50D and on 70D. The difference between the points gives you an idea if the lens is improving with another body.
And make yourself clear: A lens will never get worse on a better body. Only the pictures/results could get less sharp. So, one should always remember, the PZ test results are valid for the lens AND body combination. Some aspects would remain the same on a better body - like vignetting or distortion. Others could improve. And things like higher dynamic range which is improving the picture's contrast, has nothing to do with the lens in front of sensor.
