我正在对有角度的项目执行单元测试，但出现错误

“未捕获的ReferenceError：未定义区域”

在茉莉花和业力中。目前，我使用的是角度6。

Answer 1

我在Angular 9中遇到了同样的问题。

我在“ test.ts”文件中添加了一些导入和一个窗口的polyfill。在完整文件下方。

// This file is required by karma.conf.js and loads recursively all the .spec and framework files

import 'zone.js/dist/zone';
import 'zone.js/dist/long-stack-trace-zone';
import 'zone.js/dist/proxy';
import 'zone.js/dist/sync-test';
import 'zone.js/dist/jasmine-patch';
import 'zone.js/dist/async-test';
import 'zone.js/dist/fake-async-test';
import 'zone.js/dist/zone-testing';
import { getTestBed } from '@angular/core/testing';
import {
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting
} from '@angular/platform-browser-dynamic/testing';

(window as any).global = window;

declare const require: {
  context(path: string, deep?: boolean, filter?: RegExp): {
    keys(): string[];
    <T>(id: string): T;
  };
};

// First, initialize the Angular testing environment.
getTestBed().initTestEnvironment(
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting()
);
// Then we find all the tests.
const context = require.context('./', true, /\.spec\.ts$/);
// And load the modules.
context.keys().map(context);

通过下面的链接，对您有所帮助。

https://github.com/angular/zone.js/issues/776

update employees e
set e.employee_ID = 'EMP006'
where e.employee_ID in (select e.employeeID from employees, employee_type et
                     where employee_type = 'CASUAL'
                     and e.employee_id = et.employee_id);
dbms_output.put_line('expected inserted records:44,actual:'||SQL%ROWCOUNT);

Answer 3

我不知道这是否仍然是一个问题，但如果一切正常但仍然无法正常工作，请在 karma.conf.js 文件中尝试以下操作：

config.set({... files: ['node_modules/zone.js/dist/zone.js'] });
