[ClojureScript] Run all tests in multiple namespaces in REPL

From ClojureScript wiki, it says

If you have many test namespaces it's idiomatic to create a test runner namespace which imports all of your test namespaces and then invokes run-tests

I personally couldn't get it to work. Though I have managed to make run-all-tests works. This is an example

(ns myns.test.runner
  (:require [cljs.test :refer-macros [run-all-tests]]
            [myns.test.ns1]
            [myns.test.ns2]))

(run-all-tests #"myns.test.*")

[DataScript][Solved] Error: Expected number or lookup ref for entity id, got

When you are trying to use Map specification of Datomic's pull api and you got this error

Error: Expected number or lookup ref for entity id, got ....

This happens because you didn't specify schema for that data attribute. Schema is optional on DataScript but it is required in this case. Add this line to your database, the issue should be fixed

{:your-attribute1 {:db/valueType :db.type/ref}
 :your-attribute2 {:db/valueType :db.type/ref}}
