Ok guys, here is what the SANS 10047 (South African National Standard) states about the shocks. In other words, the reasons why it might have failed:
SANS 10047:2009
Edition 6
5.44 Suspension units
5.44.1 Springs
Reject if
a) any spring is broken or sagging, or has been "packed" (to counter sagging) with materials or all
steering components (ball joints), or components other than those specified by the
manufacturer, or
b) any spring leaf or U-bolt is missing or is loose, broken or cracked, or
c) a spring centre bolt or clip is missing or is broken, or
d) the springs do not maintain the unladen vehicle in a reasonably level position, or
e) there is any crack in the spring cradle, or
f) any part shows signs of having been repaired by heating or welding.

So for any of those reasons they can, and most likely will fail your car. After all, they have to make their money somehow.
