Jasmine tests check if html contains text and return boolean
提问by Spdexter
expect(view.$el.html()).toContain('Admin');
The view does contain the word 'Admin' so I was expecting it to return true. How can I achieve this?
该视图确实包含“管理员”一词，因此我希望它返回 true。我怎样才能做到这一点？
expect(view.$el.html()).toContain('Admin');
This returns undefined. How can I make it return true?
这返回undefined. 我怎样才能让它回来true？
<header class="main">
<div id="heading">
<ul class="header-view right">
<li class="inline"><a href="#link" class="button help-btn tab-btn"><span> </span>Help</a></li>
<li class="inline last"><a href="#og" class="button admin-btn tab-btn expand-admin"><span></span>Admin</a></li>
</ul>
</div>
</header>
This is what is returned from view.$el.html
这是返回的内容 view.$el.html
Please help.
请帮忙。

From the Jasmine docs:
从茉莉花文档：
The 'toContain' matcher is for finding an item in an Array
'toContain' 匹配器用于在数组中查找项目
You are trying to find a string inside a string so I would do something like this:
您正在尝试在字符串中查找字符串，因此我会执行以下操作：
expect(view.$el.html().indexOf('Admin') !== -1).toBe(true);
回答by alecxe
toContain()now can actually be used for substring in string checks:
toContain()现在实际上可以用于字符串检查中的子字符串：
expect(view.$el.html()).toContain('Admin');
