The workflow as follows

Use reango test helpers to set up a logged in selenium user sitting on the home page.

Every html component involved in the test should have a css class name using BEM, which essentially is a class name with an action or state associated with it like

• button_signin-link
• button_submit-form or with variable substitution

`pollRadioButton_select-answer-${choice.name}`

The point being if you stick to this standard writing selenium tests is a breeze.
