在将React Testing Library设置到一个新项目时,我遇到一个问题,该项目为多个项目生成通用的UI组件。在其中一个项目中,它是正确设置的,但是当我在该项目中添加React Testing Library和更新依赖项时,我可以运行测试,但不能运行所有测试。
如果我这样做yarn test
,结果是:
Test Suites: 8 passed, 8 of 33 total
Tests: 84 passed, 84 total
Snapshots: 0 total

我尝试做rm -rf node_modules
,然后清理缓存,但没有用。
有帮助吗?

事实证明,通过更改package.json
中的某些库,该错误消失了:
在(KO)之前:
"babel-jest": "^24.9.0",
"jest": "^26.0.1",
(确定)之后:
"babel-jest": "^26.0.1",
"jest": "^25.5.4",

在我的情况下是节点的版本。我有版本 15(来自 Latest Features)并将其更改为稳定版本 14.17.3(来自 LTS)。
要知道您使用的是哪个版本,请在终端中使用 node -v。
