assert_select的反义词? [英] The opposite of assert_select?

问题描述

我正在编写一个应用程序，该应用程序需要检查视图是否具有某些功能-特别是因为该功能必须仅提供给特定安全组中的用户.我正在寻找assert_selects的反义词，以查看菜单是否未呈现.

I am writing an app where it is desirable to check if a view does not have some functionality - in particular because that functionality must be presented only to users in certain security group. I am looking for the opposite of assert_selects in order to see that a menu is not rendered.

推荐答案

在此处查看文档:

从文档中

assert_select是assertion that selects elements and makes one or more equality tests.

assert_select is an assertion that selects elements and makes one or more equality tests.

以及平等性测试部分:

相等性测试可能是以下之一:

The equality test may be one of the following:

true-如果至少选择了一个元素，则断言为true.

true - Assertion is true if at least one element selected.

false-如果未选择任何元素，则断言为true.

false - Assertion is true if no element selected.

字符串/正则表达式-如果文本值至少为1，则断言为true 元素匹配字符串或正则表达式.

String/Regexp - Assertion is true if the text value of at least one element matches the string or regular expression.

整数-确切地说，如果元素的数量为true，则断言为true 选择.

Integer - Assertion is true if exactly that number of elements are selected.

范围-如果所选元素的数量符合条件，则断言为true 范围.

Range - Assertion is true if the number of selected elements fit the range.

如果未指定相等性测试，则至少有一个断言为真 元素已选中.

If no equality test specified, the assertion is true if at least one element selected.

还有一个简单的例子:

   # Page contains no forms
   assert_select "form", false, "This page must contain no forms"
