title: wiping out a datomic db for test environment ?
body: <p>I'm trying to truncate my dataomic database between tests. I see a lot of questions on google about excision and how to delete data, but none about just wiping a database clean. </p>
  
  <p>I'm doing something along the following using core.test: </p>
  
  <pre><code>(with-redefs [db/uri  "datomic:free://localhost:4334/test_om_asyn101_next"
                db/conn (d/connect db/uri)]
    (run-tests 'rtest.core-test))
  </code></pre>
  
  <p>I've been wiping out the DB by changing the URI and creating anew, but getting tired of doing that! Thanks! </p>
