+# End to end tests
+
+End-to-end testing is a methodology used to test whether the flow of an
+application is performing as designed from start to finish.
+
+Tests here need to be run with a transpiled sources & a test folder ready to run
+
+```console
+npm run transpile
+npm run test-phenomic-theme-base:prepare
+npm run e2e:tests
+```
+
+Otherwise you can just use `npm test` to run every tests.
