Jasmine测试中调用ASP.NET Core Web API认证接口后代码停滞无报错的问题求助

大家好，我现在碰到一个非常棘手的问题，想请教下有没有朋友遇到过类似情况或者有解决方案：

我们团队有一套Angular应用的专属测试流程，需要通过Jasmine完成身份认证后调用ASP.NET Core Web API。因为已经搭建了大量UI测试案例，不想在集成测试里重复开发，所以要求这些UI测试既能基于模拟数据运行，也能对接真实数据。

现在的核心问题是：connectClient方法永远走不到后续代码（就是代码里标了connectClient:never gets here的断点位置）。测试看起来像是“通过”了，但在发起http.post('.../connect/token')请求之后，connectClient里剩余的代码，以及Jasmine测试中的后续设置步骤（就是标了Jasmine setup:never gets here的调试器位置）完全不执行。

我试过各种排查手段：比如设置超大的超时时间jasmine.DEFAULT_TIMEOUT_INTERVAL = 1000000;、添加done()回调，但都没效果；而且全程没有任何超时错误提示。我还试过把connectClient的调用替换成10秒的setTimeout，这时候流程就能正常等待并继续执行后续代码，完全符合预期。

下面是相关的代码片段：

Jasmine 测试代码 #

uiTestAuthService = TestBed.inject(UiTestAuthService) as jasmine.SpyObj<UiTestAuthService>;
mockData = await mockDataService.getDynamicReportData(uiTestAuthService);
debugger; //<<-- !! Jasmine setup:never gets here !!
spyOn(mockCommonService, 'getReportData').and.returnValue(mockData);
...

beforeEach(async () => {
    //jasmine.DEFAULT_TIMEOUT_INTERVAL = 1000000;
    fixture = TestBed.createComponent(ComponentToBeTested);
    component = fixture.componentInstance;
    await fixture.whenStable();
});

...

it('should render correctly', fakeAsync(() => {
    component = fixture.componentInstance;
    expect(component).toBeTruthy();
}));

MockDataService 代码 #

export class MockDataService {
    async getDynamicReportData(uiTestAuthService: UiTestAuthService, myReportTypeId: any): Promise<any> {
        var http: HttpClient;
        var token;
        [token, http] = await uiTestAuthService.connectClient(
            'https://identity-server.my-domain.com',
            'client_credentials',
            'my-client-id',
            'my-client-secret'
        );

        if (token) {
            var url = 'https://api.my-domain.com';
            var reportTypeId = 9999;
            let apiUrl = `${url}/api/Report/${reportTypeId}`
            var json = JSON.parse('{"MyVariable1":"my-value-1","MyVariable2":"my-value-2",...}')
            const headers = new HttpHeaders().set('Authorization', `Bearer ${token}`);
            return http.post(apiUrl, JSON.stringify(json), { headers }).pipe(map((resp: any) => {
                return Promise.resolve(resp.Result.Data);
            }));
        }
    }
}

UiTestAuthService 的 connectClient 方法 #

export class UiTestAuthService {
    http: HttpClient;

    constructor(
        httpClient: HttpClient
    ) {
        this.http = httpClient;
    }

    async connectClient(
        authBaseAddress: string,
        grant_type: string,
        client_id: string,
        client_secret: string
    ): Promise<[string, HttpClient] | null> {
        const form = new HttpParams()
            .set('grant_type', grant_type)
            .set('client_id', client_id)
            .set('client_secret', client_secret);

        let retry = false;
        let retryCount = 0;
        let jsonContent: any = null;
        var _this = this;

        do {
            try {
                const response = await firstValueFrom(
                    _this.http.post<any>(`${authBaseAddress}/connect/token`, form.toString(), {
                        headers: new HttpHeaders({
                            'Content-Type': 'application/x-www-form-urlencoded'
                        })
                    })
                    .pipe(
                        catchError(error => {
                            console.error('Error during token retrieval:', error);
                            return throwError(() => new Error('Failed to get authentication token'));
                        })
                    )
                )
                debugger; //<<-- !! connectClient:never gets here !!
                jsonContent = response;
                retry = false;
            } catch (error) {
                console.error(`An error occurred while acquiring a token\nTime: ${new Date()}\nError:`, error);
                retry = true;
                retryCount++;
                await new Promise(res => setTimeout(res, 30000)); // wait 30 seconds
            }
        } while (retry && retryCount < 3);

        if (!jsonContent) {
            console.warn('Cancelling attempt to contact the report service.');
            return null;
        }

        const accessToken = jsonContent.access_token;
        return Promise.resolve([accessToken, _this.http]);
    }
}

有没有朋友遇到过类似的问题？或者能给我一些排查的方向？
