A DNA test is usually not the beginning or the end of genealogy research. A genetic genealogy test could help you identify biological relatives, connect with distant cousins, and give you more avenues for future genealogy research. A DNA test is not very useful unless you already have a basic family tree to compare with your DNA matches. Otherwise, you cannot identify the common ancestors that link you. You will need documented genealogy research to understand your DNA connections and build out your tree.
