unit-testing - 如何在 Angular2 rc5 中导入 jasmine 测试函数

Question

我正在开发一个新项目，刚刚从 Angular 2 的 rc4 升级到 rc5。升级后，它、expect、describe 等函数似乎不再从“@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仍然具有这些 Jasmine 测试功能的 rc5。你在哪里使用 rc5 导入这些？是否缺少新的依赖库？

Answer 1

从 RC4 开始，它们不再需要从任何地方导入。它们在全局范围内可供任何测试模块使用。

Importing Jasmine functions from @angular/core/testing is 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.
