The idea behind The Wilcoxon Signed-Rank Test is to median-center the samples and give signed-ranks to the individual values. If the sum of the negative ranks (S-) is larger, we can conclude that the population mean is lesser than the mentioned value. If the sum of the positive ranks(S+) is larger, the population mean is greater than the mentioned value.
