为什么 Karma 会跳过我的有效单元测试？

Question

我在 Angular 10 项目中与 Karma 合作。我正在尝试测试选择器，我可以通过运行ning npm run test-report 看到文件显示在所有文件列表中，但是当我运行测试时我可以看到文件是跳过。我什至尝试在 describe 之前放一个 f 并且 karma 仍然跳过它。此测试与我运行的其他测试几乎完全相同，因此令人费解。请参阅下面的相关 selector.spec 文件代码和我的业力配置。

import { SupportState } from './reducers';
import { supportConfig } from './support.constant';
import * as selectors from './support.selectors';

fdescribe('SupportSelectors', () => {
    let supportConfiguration;
    let myFaqs;

    let state: SupportState;

    beforeEach(() => {
       supportConfiguration = supportConfig;

        myFaqs = {
            answer: "<p>Once signed in to Member Online Services, you can find out if you have coverage for Durable Medica;",
            question: "Am I covered for Durable Medical Equipment (DME) such as breast pumps, sleep apnea machines and orthotics???",
            id: 15,
            name: "Benefits"
        }

        state = {
            config: supportConfiguration,
            faqs: myFaqs,
            category: myFaqs.name,
            error: undefined
        };

       it('should return the configuration for Support', () => {
            expect(selectors.selectSupportConfig.projector(state)).toEqual(supportConfiguration);
        });

        it('should return faqs', () => {
            expect(selectors.selectSupportFAQs.projector(state)).toEqual(myFaqs);
        });

        it('should return category', () => {
            expect(selectors.selectSupportFAQCategory.projector(state)).toEqual(myFaqs.name);
        });

    });
});

// Karma configuration file, see link for more information
// https://karma-runner.github.io/1.0/config/configuration-file.html

module.exports = function (config) {
    config.set({
        basePath: '',
        frameworks: ['jasmine', '@angular-devkit/build-angular'],
        plugins: [
            require('karma-jasmine'),
            require('karma-chrome-launcher'),
            require('karma-jasmine-html-reporter'),
            require('karma-coverage-istanbul-reporter'),
            require('@angular-devkit/build-angular/plugins/karma'),
        ],
        client: {
            clearContext: false, // leave Jasmine Spec Runner output visible in browser
        },
        coverageIstanbulReporter: {
            dir: require('path').join(__dirname, './coverage/member-portal'),
            reports: ['html', 'lcovonly', 'text-summary'],
            fixWebpackSourcePaths: true,
        },
        reporters: ['progress', 'kjhtml'],
        port: 9876,
        colors: true,
        logLevel: config.LOG_INFO,
        browserNoActivityTimeout: 60000,
        browserDisconnectTimeout: 60000,
        autoWatch: true,
        browsers: ['Chrome', 'ChromeHeadless'],
        singleRun: false,
        customLaunchers: {
            ChromeHeadless: {
                base: 'Chrome',
                flags: ['--headless', '--disable-gpu', '--no-sandbox', '--remote-debugging-port=9222'],
            },
        },
        restartOnFileChange: true,
    });
};

看起来您的 it() 期望嵌套在您的 beforeEach 块中。他们应该是 beforeEach 的同行，或者是最近的 describe.

的直属
