我尝试用茉莉花测试对主干视图的正确模板分配。
这是我的测试:
describe("Backbone views", function() {
// Runs before every View spec
beforeEach(function() {
// Instantiates a new View instance
this.view = new Index();
});
it("should contain the appropriate template", function() {
expect(this.view.template).toEqual(IndexViewTemplate);
});
}
在 render 函数中填充 view.template 变量:
initialize: () ->
super()
@render()
# Renders the view's template to the UI
render: () ->
# Setting the view's template property using the Underscore template method
@template = _.template template,
{}
# Dynamically updates the UI with the view's template
@$el.html @template
# Maintains chainability
return @
变量 IndexViewTemplate 包含原始模板代码,其中包含 <% if (...) %> 之类的逻辑内容。
当我运行该代码时,我得到一个异常,这两个元素不相等,因为在 this.view.template 中,逻辑部分......被渲染掉......;):
should contain the appropriate template
Expected
'<!-- HTML Template --> <div class="page"> <header class="navbar navbar-inner navbar-fixed-top"> <div class="nav pull-left"> <a href="#" class="btn" type="submit">Back</a> </div> <div> <a class="brand">Backbone-Require-Boilerplate (BRB)</a > </div> <div class="nav pull-right"> <a href="#next" class="btn" type="submit">Next</a> </div> </header> <!-- /header --> <div class="container-fluid"> <div class="row-fluid"> <div class="span12"> <div class="content"> </div> </div> </div> </div> <footer class="footer navbar navbar-fixed-bottom"> <div class="navbar-inner"> <p>Written by <a href="https://github.com/hijolan" target="_blank">Constantin Lebrecht</a></p> </div> </footer><!-- /footer --> </div> <!-- /page --> '
to equal
'<!-- HTML Template --> <div class="page"> <header class="navbar navbar-inner navbar-fixed-top"> <div class="nav pull-left"> <% if (titleBar.backButton.title.length > 0) {%> <a href="<%= titleBar.backButton.href %>" class="btn" type="submit"><%= titleBar.backButton.title %></a> <% } %> </div> <div> <a class="brand"><%= titleBar.title %></a > </div> <div class="nav pull-right"> <% if (titleBar.actionButton.title.length > 0) {%> <a href="<%= titleBar.actionButton.href %>" class="btn" type="submit"><%= titleBar.actionButton.title %></a> <% } %> </div> </header> <!-- /header --> <div class="container-fluid"> <div class="row-fluid"> <div class="span12"> <div class="content"> <%= content.text %> </div> </div> </div> </div> <footer class="footer navbar navbar-fixed-bottom"> <div class="navbar-inner"> <p>Written by <a href="https://github.com/hijolan" target="_blank">Constantin Lebrecht</a></p> </div> </footer><!-- /footer --> </div> <!-- /page --> '.
测试作业的最佳方法是什么?
