我正在开发一个新项目，刚刚从 Angular 2 的 rc4 升级到 rc5。升级后，似乎像 it、expect、describe 等功能不再从“@angular/core/testing”导出。我搜索了我能想到的所有资源，我看到在线编写的单元测试声称使用 rc5，但仍然具有这些 Jasmine 测试功能。你从哪里使用 rc5 导入这些？我是否缺少新的依赖库？

最佳答案
从 RC4 开始，它们不再需要从任何地方导入。它们可在全局范围内供任何测试模块使用。
Importing Jasmine functions from
@angular/core/testingis no longer necessary and is now deprecated.
另请参阅 Breaking Changes section of the RC4 Changelog 的最后一个要点.
