unit tests

• take the smallest piece of testable software in the application
• isolate it from the remainder of the code
• determine whether it behaves exactly as you expect

  wiki

integration tests

• individual software modules are combined and tested as a group

  When I visit the login page
  And fill out the account signup
  I should receive an email about it
  And I should be logged in

acceptance tests

• contract
• the soup should not be cold
• the soup should not be less than 90 degrees
• the soup should not be less than 90 degrees Fahrenheit
