Question

在完成Michael Hartl的Ruby on Rails教程时，我在执行rails test时遇到了错误，可以使用一些帮助来解决这个问题：

错误消息表明您已在文件test_layout_links中定义了方法test/integration/site_layout_test.rb。

它有可能发生两次吗？

像：

def test_layout_links
  ...
end

def test_layout_links
  ...
end

或者，如果您使用DSL，它可能如下所示：

test "layout_links" do
  ...
end

test "layout_links" do
  ...
end

无论哪种方式，只需删除或重命名。
