Clojurians Log v2

Pretty new to this. Trying to make some tests for some validator functions within my routes. Writing a function called validate-email in clj/routes/home.clj. Where is the best practice place to put that test? test/clj/<PROJ>/test/handler.clj or test/clj/<PROJ>/test/routes/home.clj

if you defined it in /src/routes/home.clj then test/routes/home.clj
