In order to test the first e2e, error-

• checkout the bs/react branch on test-snaps
• yarn install && yarn build && yarn start
  that will start the servers for the test page

to run the tests:

• rm -r node_modules && yarn setup && yarn build:test:flask - this should work unless you get lavamoat errors later
• SELENIUM_BROWSER=chrome yarn test:e2e:single test/e2e/snaps/test-snap-error.spec.js --leave-running - this will leave the page running until you ^c out of it when the test fails

[bowensanders]

Tests are failing on the bip-32 snap test, as if the new key-tree changers aren't merged here.
