test to check that before filter is being run?

What do these before filters do? Here’s an example:

Say I have a before_filter called “find_my_record” since my edit, show, delete, and update all call @user = User.find(params[:id])

before_filter :find_my_record, :only=>[:edit, :update, :show, :delete]

def edit
end

def delete
@user.destroy
end

protected
def find_my_record
@user = User.find(params[:id])
end

Then I have a functional test that looks like this:

def test_edit
get :edit, {:id=>1}
assert_response :success
assert_not_nil assigns(:user) # this should be filled in if the before filter ran.
end

Basically, it all comes down to what your before_filter is actually doing. If it redirects certain users away, write a test helper that does that.

def test_should_not_let_normal_users_delete
get :delete, {:id=>1} # note no session passed in
assert_response :redirected
assert_equal flash[:notice], “You do not have access to that feature.”

end

def test_should_let_admins_delete
get :delete, {:id=>1}, {:user => 1} # should get this from a fixture instead of hard-coding
assert_response :redirected
assert_equal flash[:notice], “Record deleted successfully.”

end

Does that help?
