我在reactjs项目中将史诗用于我的redux。
我有一部使用forkJoin的史诗，类似这样：
"dependencies": {
"@angular/common": "6.1.0",
"@angular/compiler": "6.1.0",
"@angular/core": "6.1.0",
"@angular/forms": "6.1.0",
"@angular/platform-browser": "6.1.0",
"@angular/platform-browser-dynamic": "6.1.0",
"@angular/router": "6.1.0",
"@fortawesome/angular-fontawesome": "0.1.1",
"@fortawesome/fontawesome-svg-core": "1.2.2",
"@fortawesome/free-solid-svg-icons": "5.2.0",
"@ng-bootstrap/ng-bootstrap": "2.2.1",
"bootstrap": "4.1.3",
"core-js": "2.5.7",
"jquery": "3.3.1",
"moment": "2.22.2",
"ng-jhipster": "0.5.4",
"ngx-cookie": "2.0.1",
"ngx-infinite-scroll": "0.5.1",
"ngx-webstorage": "2.0.1",
"reflect-metadata": "0.1.12",
"rxjs": "6.1.0",
"rxjs-compat": "6.1.0",
"swagger-ui": "2.2.10",
"sockjs-client": "1.1.4",
"webstomp-client": "1.2.0",
"tslib": "1.9.3",
"zone.js": "0.8.26"
}
如何为此功能编写单元测试？
