+## A collection of playwright tests run on the web3-onboard demo
+
+To run tests:
+1. Create .env file in test/ with the following variables:
+    TEST_WALLET_PHRASE
+    TEST_WALLET_ADDRESS
+    SERIAL_MODE=true
+    HEADLESS_MODE=true
+2. yarn test
+
+There are 4 existing tests for metamask: connect metamask, sign a message, sign a typed message, send a transaction, switche chains, and disconnect. 
+
+Please note: your test metamask wallet must have a balance of GoerliETH for all tests to pass. 
+
+To view report after running tests: npx playwright show-report
