Tipps and tricks

Test for exceptions

Sometimes you want to check if an exception is thrown. For that you can use assert_raise

assert_raise(RuntimeError) { #Code that should throw a RuntimeError }

Use setup and teardown in tests to initialize your testdata

setup is always called before a test starts and teardown when the test is finished. So you can write

@user

def setup
  @user = Models::User.created(..data)
end

def teardown
  @user.clear
end

def test1
  #Do something with @user
end

Instead of

def test1
  user = Models::User.created(..data)
  #Do something with user
  user.clear
end

# ... A lot of tests using a user ...

def test100
  user = Models::User.created(..data)
  #Do something with user
  user.clear
end

Make links to post a form

Use java-script for that

<form action='/unregister' name='data' method='POST'></form>
<a href="javascript:data.submit()">Delete Account</a>

See our Menu for an example
