本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

案例
HOW- 目标
- Jest requires setupFilesAfterEnv rather than setupFiles to register test framework lifecycle hooks and custom matchers because setupFiles runs before the test framework is installed
- 符号
-
- setupFiles
- setupFilesAfterEnv
- normalize
- 环境
- node
- 创建时间
- 2026-08-17T01:53:57Z
契约
- assert running Jest with test framework hooks in setupFiles fails with ReferenceError: beforeEach is not defined because the framework environment is not yet initialized
- assert setupFiles executes in the isolated test environment before the test framework and can configure environment globals
- assert setupFilesAfterEnv executes after test framework initialization, allowing beforeEach hooks and expect.extend matchers to run across test suites
- assert jest-config normalize correctly resolves <rootDir> tokens for both setupFiles and setupFilesAfterEnv into absolute paths
