The practical line testers are works for the voltages above
150v. The return path is earth (land surface) via human body.
When you touched to line the voltage across the tester is
230v. If you touched to neutral the voltage across the
tester is in order of 2-10V depending up on the conditions
of distribution transformer.
so the tester will not work.
