我正在使用 Angular2 final (2.0.2) 和 angular-cli。我正在尝试将其设置为使用 PhantomJS 运行单元测试。使用 Chrome 和 karma-chrome-launcher 运行规范 - 所有测试都通过。使用 Phantomjs-prebuilt 2.1.13 和 karma-phantomjs-launcher 1.0.2 运行相同的测试失败。
我将 phantomjs 启动器添加到 karma.conf 中的 plugins 数组，以及 browsers 数组中的 PahntomJS。
我得到的错误是：

也许我在 angular-cli 创建的 test.ts 文件中缺少一些配置？
更新：
似乎只有导入失败的测试DatePipe和JsonPipe.
我也尝试导入@angular/common/testing，test.ts但这无济于事 - 它们没有在相关的 index.js 中导出。
还尝试导入整个文件@angular/common/pipes，但这也不起作用。
这是管道：
import { Pipe, PipeTransform } from "@angular/core";
import { DatePipe, JsonPipe } from "@angular/common";
@Pipe({name: 'dataTableFormat'})
export class DataTablePipe implements PipeTransform {
// values with type 'json' are parsed to json. As a result, string values may be displayed with quotes ("<string>").
// To avoid that, we remove these quotes with this regex
private quotesExp: RegExp = /^\"|\"$/gi;
constructor(private datePipe: DatePipe, private jsonPipe: JsonPipe) {
}
transform(value: any, type: string): string {
switch (type) {
case "date":
return this.datePipe.transform(value, 'short');
case "json":
return this.jsonPipe.transform(value).replace(this.quotesExp, "");
default:
return value;
}
}
}
和规格：
import { inject, TestBed } from "@angular/core/testing";
import { DataTablePipe } from "./data-table.pipe";
import { DatePipe, JsonPipe } from "@angular/common";
describe('DataTableFormat', () => {
beforeEach(() => {
TestBed.configureTestingModule({
providers: [
DatePipe, JsonPipe
]
});
});
it('should transform date in milliseconds', inject([DatePipe, JsonPipe], (datePipe, jsonPipe) => {
let pipe = new DataTablePipe(datePipe, jsonPipe);
let testDate: Date = new Date();
expect(pipe.transform(testDate.getTime(), 'date')).toBe(datePipe.transform(testDate, 'short'));
}));
it('should transform date string', inject([DatePipe, JsonPipe], (datePipe, jsonPipe) => {
let pipe = new DataTablePipe(datePipe, jsonPipe);
let testDate: Date = new Date();
expect(pipe.transform(testDate.toISOString(), 'date')).toBe(datePipe.transform(testDate, 'short'));
}));
it('should transform json', inject([DatePipe, JsonPipe], (datePipe, jsonPipe) => {
let pipe = new DataTablePipe(datePipe, jsonPipe);
let testJson = {
prop1: "val1",
prop2: "val2"
};
expect(pipe.transform(testJson, 'json')).toBe(jsonPipe.transform(testJson));
}));
});
这是我的文件-与...test.ts生成的文件没有太大变化angular-cli

Promise.all([
System.import('@angular/core/testing'),
System.import('@angular/platform-browser-dynamic/testing'),
System.import('../../../node_modules/nvd3/build/nv.d3.min.js'),
])
// First, initialize the Angular testing environment.
.then(([testing, testingBrowser]) => {
testing.getTestBed().initTestEnvironment(
testingBrowser.BrowserDynamicTestingModule,
testingBrowser.platformBrowserDynamicTesting()
);
})
// Then we find all the tests.
.then(() => require.context('./', true, /\.spec\.ts/))
// And load the modules.
.then(context => context.keys().map(context))
// Finally, start Karma to run the tests.
.then(__karma__.start, __karma__.error);
知道为什么这适用于 Chrome 而不是 PhantomJS 吗？
