Practice app · Acme Ops
A sign-in page with field validation and an authenticated dashboard.
Your starter code already declares TEST_URL — never hardcode a host.
Objective
Design page methods that return the page itself so a sign-in reads as one fluent chain.
Your task
- 1Give LoginPage chainable methods open(), enterEmail(text), enterPassword(text) that return this/self.
- 2submit() clicks #login-button and returns a DashboardPage.
- 3Write the flow as one chain: open().enterEmail("qa@target.dev").enterPassword("Test@123").submit().
- 4Assert the welcome message on the returned DashboardPage.
Acceptance criteria
- Methods return this/self and are chained
- The dashboard is shown with the welcome message
- At least 1 assertion passes
Fixtures
- username
- qa@target.dev
- password
- Test@123
