我这里有一个超级边缘案例。
我正在围绕一个 jQuery 插件编写一个包装器指令,该插件将一个简单的 html 元素转换为一个正式的面向反馈的视图。
<div my-directive>DirectiveContent</div>
由于插件不知道如何处理它。我的指令将其转换为如下内容:
<div my-directve><div class='myPlugin' ng-include></div></div>
此时我触发插件的 init 函数来进行最终渲染。(除其他外,它还创建了一个标题元素。)
<div my-directve><div class='feedback feedbackSuccess' ng-include>
<h2>Title</h2>
My Content
</div></div>
问题是,在我的业力茉莉花测试中,我可以做一个测试。如果我再做一个,它就行不通了。
这是我的指令:
module.directive("feedback", function(){
return {
restrict : "EA",
replace : false,
transclude : true,
require : "feedback",
template : "<div class='feedback' ng-transclude></div>",
controller : function(){
this.init = function(element){
plugin.init(element);
}
},
link : function(scope, element, attrs, cntrl){
var feedback = element.find(".feedback");
var type = scope.$eval(attrs.type) || "";
var title = scope.$eval(attrs.title) || "";
//route standard ric:xxx to actual child feedback element
feedback.attr("ric:title", title );
feedback.attr("ric:type", type );
cntrl.init(feedback);
}
};
});
这是我的 karma.conf.js:
basePath = '';
files = [
JASMINE,
JASMINE_ADAPTER,
"path/to/plugin.js",
"components/angular-unstable/angular.js",
"components/angular-mocks/angular-mocks.js",
{
"pattern" : "./src/FeedbackDirective.js",
"watched" : true,
"included" : true,
"served" : true
},
{
"pattern" : "./tests/app.js",
"watched" : true,
"included" : true,
"served" : true
},
{
"pattern" : "./tests/fixtures/*.html",
"watched" : true,
"included" : true,
"served" : true
},
'./tests/**/*Spec.js'
];
// list of files to exclude
exclude = [];
preprocessors = {
'./tests/fixtures/*.html': 'html2js'
};
reporters = ['progress'];
port = 9876;
runnerPort = 9100;
colors = true;
logLevel = LOG_INFO;
autoWatch = true;
browsers = ['Chrome'];
captureTimeout = 60000;
singleRun = false;
最后是我的测试:
describe('Feedback', function(){
var $compile;
var $rootScope;
var $templateCache;
var $timeout;
var testWrap;
beforeEach(module(
'app',
"tests/fixtures/vanilla.html"
));
beforeEach(function(){
inject(function(_$compile_, _$rootScope_, _$templateCache_, _$timeout_){
$compile = _$compile_;
$rootScope = _$rootScope_;
$templateCache = _$templateCache_;
$timeout = _$timeout_;
testWrap = angular.element("<div id='test-wrap'></div>");
});
});
afterEach(function(){
$rootScope.$destroy();
testWrap.remove();
});
/**
* Test ONE
*/
describe("'Vanilla'", function(){
it("will be instantiated with a 'feedbackSuccess' class", function(){
var tmpl = angular.element('<div my-feedback>Test Content</div>');
element = $compile(tmpl)($rootScope);
testWrap.append(element);
$rootScope.$digest();
expect( testWrap.find(".feedback").length ).toBe(1);
expect( testWrap.find(".feedbackSuccess").length ).toBe(1);
});
});
/**
* Test TWO
*/
describe('With attributes', function(){
it("should pass the title and type to the child feedback element", function(){
var tmpl = angular.element('<div my-feedback ric:title="\'Static Title\'" ric:type="\'error\'">Test Content</div>');
element = $compile(tmpl)($rootScope);
testWrap.append(element);
$rootScope.$apply();
expect( testWrap.find(".feedbackError").length ).toBe(1);
});
});
});
