+# Use mocha for JS unit testing framework
+
+- Status: accept
+- Deciders: Arthur Lu, Marc Reta
+- Date: 11 / 12 / 22
+
+## Decision Drivers
+
+- Need specification on how to write unit testing assertion statements
+- Need framework to perform unit testing quickly for immediate code feedback
+
+## Considered Options
+- JUnit5
+- Jest
+- Mocha
+
+## Decision Outcome
+
+Chosen Option: Mocha because it was significantly faster to run than Jest (1s vs 30s), and can use a variety of assertion styles unlike JUnit5.
