我的组件是
getHomePageData() : void{
this.homeservice.getHomePageData()
.subscribe(
data => {
//console.log("response status ################### "+data.status);
//console.log("getUserData response ************ \n"+JSON.stringify(data));
this.defaultFacilityId = data.response.defaultFacilityId;
this.defaultFacilityName = data.response.defaultFacilityName;
this.enterpriseId = data.response.enterpriseId;
this.enterpriseName = data.response.enterpriseName;
this.facilityList = data.response.facilityList;
this.userName = data.response.userName;
this.showDefaultPopoup();
},error => {
console.error(error);
//this.errorMessage="Technical error - Contact Support team !" ;
}
);
}
所以我的component.spec.ts是,
it('getHomePageData with SUCCESS - getHomePageData()',() => {
backend.connections.subscribe((connection: MockConnection) => {
//expect(connection.request.url).toEqual('http://localhost:8080/MSMTestWebApp/UDM/UdmService/Home/');
expect(connection.request.url).toEqual('http://192.168.61.158:9080/GetUserData');
expect(connection.request.method).toEqual(RequestMethod.Get);
expect(connection.request.headers.get('Content-Type')).toEqual('application/json');
let options = new ResponSEOptions({
body:
{
"request": { "url": "/getUserData" },"response": {
"defaultFacilityName":"3M Health Information Systems","enterpriseId":"11.0","enterpriseName":"HSA Enterprise","defaultFacilityId": "55303.0","userName":"Anand"
},"error": ""
},status : 200
});
connection.mockRespond(new Response(options));
});
backend.connections.subscribe((data) => {
//expect(data.response.facilityId).toEqual("55303.0");
//expect(subject.handleError).toHaveBeenCalled();
})
service.getHomePageData().subscribe((data) => {
//expect(videos.length).toBe(4);
expect(data.response.defaultFacilityId).toEqual("55303.0");
component.defaultFacilityId = data.response.defaultFacilityId;
component.defaultFacilityName = data.response.defaultFacilityName;
component.enterpriseId = data.response.enterpriseId;
component.enterpriseName = data.response.enterpriseName;
component.userName = data.response.userName;
console.log("$$$$$$$$$$$$$$$$**********$$$$$$$$$$$$$$$$$$$$$");
});
});
当我尝试运行测试用例.已经过去了但是,当我研究代码覆盖时,它不包括红色低于的代码
请帮助获得完整的代码报道.谢谢.
在您在此处显示的测试中,您似乎没有从您的组件调用getHomePageData()
原文链接：https://www.f2er.com/angularjs/142771.html尝试建立这样的测试：
import { fakeAsync,tick } from '@angular/core/testing';
...
it('getHomePageData with SUCCESS - getHomePageData()',fakeAsync(() => {
backend.connections.subscribe((connection: MockConnection) => {
//expect(connection.request.url).toEqual('http://localhost:8080/MSMTestWebApp/UDM/UdmService/Home/');
expect(connection.request.url).toEqual('http://192.168.61.158:9080/GetUserData');
expect(connection.request.method).toEqual(RequestMethod.Get);
expect(connection.request.headers.get('Content-Type')).toEqual('application/json');
let options = new ResponSEOptions({
body:
{
"request": { "url": "/getUserData" },"response": {
"defaultFacilityName":"3M Health Information Systems","userName":"Anand"
},"error": ""
},status : 200
});
connection.mockRespond(new Response(options));
});
// If this function is not automatically called in the component initialisation
component.getHomePageData();
tick();
//you can call expects on your component's properties now
expect(component.defaultFacilityId).toEqual("55303.0");
});
FakeAsync允许您以更线性的方式编写测试,因此您不再需要订阅服务功能来编写您的期望.
在一个FakeAsync测试函数中,您可以在进行异步操作的调用之后调用tick()来模拟一段时间,然后继续执行代码流.
您可以在这里阅读更多：https://angular.io/docs/ts/latest/testing/#!#fake-async
编辑 – 错误案例
要测试错误逻辑,您可以使用mockRespond调用mockError或设置错误响应：
it('getHomePageData with ERROR- getHomePageData()',fakeAsync(() => {
backend.connections.subscribe((connection: MockConnection) => {
if (connection.request.url === 'http://192.168.61.158:9080/GetUserData') {
// mockError option
connection.mockError(new Error('Some error'));
// mockRespond option
connection.mockRespond(new Response(new ResponSEOptions({
status: 404,statusText: 'URL not Found',})));
}
component.getHomePageData();
tick();
//you can call expects now
expect(connection.request.url).toEqual('http://192.168.61.158:9080/GetUserData');
expect(connection.request.method).toEqual(RequestMethod.Get);
expect(connection.request.headers.get('Content-Type')).toEqual('application/json');
expect('you can test your error logic here');
});
