Scenario files
The bare minimum
The minimal useful text you can put into a scenario file is
Given I am not logged in
When I log in as Morgan with a password secretPassword
Then I should see a message, "Welcome, Morgan!"
You may also use And if you have more than one Given, When or Then in your scenario.
Naming scenarios
You probably want to name your scenario which you can do like this
Scenario: Successful login
Given I am not logged in
When I log in as Morgan with a password secretPassword
Then I should see a message, "Welcome, Morgan!"
Multiple scenarios
You can of course have multiple scenarios in the same text file
Story (or Feature)
To describe your story you write the following
Story: Login
Scenario: Successful login
Given I am not logged in
When I log in as Morgan with a password secretPassword
Then I should see a message, "Welcome, Morgan!"
You may replace Story with Feature if that suits you better.
There's also room for a narrative for your story, it must currently be in As a x, I want y, So that z
Story: Login
As a x
I want y
So that z
Scenario: Successful login
Given I am not logged in
When I log in as Morgan with a password secretPassword
Then I should see a message, "Welcome, Morgan!"
