As for whether it will affect the quality of the signal, it depends on how fast and the signal is determined by the test point and the signal.
Basically, the testing point of the outer plus (Via or DIP PIN is not used as a test point) may add online or pull a small segment from online
The former is equivalent to adding a small capacitance online, and the latter is a branch of a branch.
Both situations will have a little or less affecting high -speed signals. The degree of influence is related to the frequency speed and signal change rate of signal
The impact can be learned through simulation
In principle, the smaller the test point, the better (of course, to meet the requirements of the testing machine), the shorter the branch, the better
