问题描述
我开始学习角2,并希望得到正确的事情与单元测试。所以,我想我所有的指令/组件与测试写。
在angularJS(第一版)来测试指令,可以使用 $编译
。下面是从文档的例子:
它('替换为相应的内容元素',函数(){
VAR元= $编译(<一个伟大眼>< / A-大眼>中)($ rootScope);
$ rootScope $摘要()。
期待(element.html())toContain(无盖,缭绕火焰,2次);
});
如何编译HTML文本在角2编写测试?
我想测试simpliest direcive:
进口{}组件从angular2 /核心;
@零件({
选择:电子邮件,
模板:`你好Email`
})
出口类EmailComponent {
}
使用 TestComponentBuilder
像这个例子所示,从https://github.com/angular/angular/blob/9e44dd85ada181b11be869841da2c157b095ee07/modules/angular2/test/common/directives/ng_for_spec.ts
它('应反映添加的元素',
注([TestComponentBuilder,AsyncTestCompleter](TCB:TestComponentBuilder,异步)=> {
tcb.overrideTemplate(TestComponent,模板)
.createAsync(TestComponent)
。然后((夹具)=> {
fixture.detectChanges(); (小于数[]≥fixture.debugElement.componentInstance.items).push(3);
fixture.detectChanges(); 期待(fixture.debugElement.nativeElement).toHaveText(1; 2; 3;');
async.done();
});
}));
I started to learn angular 2 and want to get things right with unit test. So I want all my directives/components to write with tests.
In angularJS (first version) to test directive You use $compile
. Here's example from doc:
it('Replaces the element with the appropriate content', function() {
var element = $compile("<a-great-eye></a-great-eye>")($rootScope);
$rootScope.$digest();
expect(element.html()).toContain("lidless, wreathed in flame, 2 times");
});
How to compile html text in angular 2 to write a test?
I want to test simpliest direcive:
import {Component} from 'angular2/core';
@Component({
selector: 'email',
template: `Hello Email`
})
export class EmailComponent {
}
Use TestComponentBuilder
like shown in this example from https://github.com/angular/angular/blob/9e44dd85ada181b11be869841da2c157b095ee07/modules/angular2/test/common/directives/ng_for_spec.ts
it('should reflect added elements',
inject([TestComponentBuilder, AsyncTestCompleter], (tcb: TestComponentBuilder, async) => {
tcb.overrideTemplate(TestComponent, TEMPLATE)
.createAsync(TestComponent)
.then((fixture) => {
fixture.detectChanges();
(<number[]>fixture.debugElement.componentInstance.items).push(3);
fixture.detectChanges();
expect(fixture.debugElement.nativeElement).toHaveText('1;2;3;');
async.done();
});
}));
