There's 3 thoughts about current setup of e2e tests:

• They don't meet out eslint standard. which we'll cover with Jenkins doesn't fail if there are eslint errors in tests #548
• It depicts active peer as Offline in all the tests. even though it makes all the Api calls successfully.
• we always have to fun e2e-test-setup.sh before running e2e-test, why not merging these together?
• Some of tests are written based on classnames belonging to the theme framework and thus vulnerable to theme changes.
