They definitely can't test the physical properties of the line with DACS in
place. However, the phrase "testing the line" includes checking their
records to see if the appropriate equipment exists at the exchange and so
on.
The presence of a DACS unit would prevent you getting a clear "pass"
initially (because the DACS unit has to be removed first before they can do
other tests). If they have indeed removed the DACS unit (not always possible
if all other lines are already DACSed) then they can do various tests that
measure the noise, attenuation and crosstalk of the line and predict fairly
accurately whether ADSL will work reliably.
If this test fails, then you are out of luck for now. But ADSL technology
improves all the time and they may have plans to pull new cable to your
area, so it's worth trying again in future, especially if it was a marginal
failure.
