我最近将最新的Jest版本引入了一个node / typescript项目，而我们之前的100％测试覆盖率（woo）下降了。
获得25个覆盖率结果（稍作更改后）：
Jest: "global" coverage threshold for statements (100%) not met: 99.83%
Jest: "global" coverage threshold for branches (100%) not met: 99.05%
Jest: "global" coverage threshold for lines (100%) not met: 99.81%
最多26个覆盖范围结果：
Jest: "global" coverage threshold for statements (100%) not met: 84.21%
Jest: "global" coverage threshold for branches (100%) not met: 68.02%
Jest: "global" coverage threshold for lines (100%) not met: 94.25%
Jest: "global" coverage threshold for functions (100%) not met: 86.44%
如果有人对更改的原因有深入的了解，我将非常感兴趣。在release notes
中，我看不到任何突出之处
