我有这个代码:
def test_create
assert_difference('Comment.count') do
post :create, :comment => {:comment => 'Comment'}
assert_not_nil assigns(:comment)
assert_equal assigns(:comment).comment, "Comment"
assert_equal assigns(:comment).valid?, true
end
assert_response :redirect
assert_redirected_to article_path(assigns(:comment))
assert_equal flash[:notice], 'Comment was successfully created.'
end
并尝试对其进行测试,但它返回:
test_create(CommentsControllerTest) [test/functional/comments_controller_test.rb:5]:
<nil> expected to not be nil.
这段代码有什么问题?请帮助我,我是 Rails 的新手
