+# Use puppeteer for JS unit testing framework
+
+- Status: accept
+- Deciders: Arthur Lu, Marc Reta
+- Date: 11 / 16 / 22
+
+## Decision Drivers
+
+- Need end to end testing framework which runs headlessly and quickly
+- Framework should integrate well with Mocha, the existing unit testing framework
+- Framework should be easy to implement end to end tests with
+
+## Considered Options
+- puppeteer
+- selenium-webdriver
+
+## Decision Outcome
+
+Chosen Option: Puppeteer for its ease of use with mocha.
