内部服务的角单元测试服务

Question

我是Angular单元测试的新手。我正在测试服务A，但是服务A取决于服务B。

服务A

export class CmsService {
    constructor(public httpService: HttpClientService) {}

    getData(url): Observable<any> {
        return this.httpService.get(url, { responseType: "text" }, "sonar");
    }
    getBannerData(url): Observable<any> {
        return this.httpService.get(url, "", "cms");
    }
}

public httpService: HttpClientService这是我的 B服务

服务B

get(url, responeType, baseURL) {
        return this.http
            .get(this.endpoint + url, responeType)
            .pipe(catchError(this.handleError));
    }

服务规范

it("getUserList() should return data", () => {
        service.getData("url").subscribe((res) => {
            expect(res).toEqual(dummyUserDetails);
        });

        const req = httpMock.expectOne(
            "https://serviceprovider.page"
        );
        expect(req.request.method).toBe("GET");
        req.flush(dummyUserListResponse);
    });

Error: Expected one matching request for criteria "Match URL: https://serviceprovider.page", found none. Requests received are: GET https://serviceprovider/json/url.

有人可以指导我对服务A做错了什么或如何对服务a进行测试。
