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。 MIT-0

契约

  1. expect.extend registers synchronous custom matchers that pass on satisfaction and throw descriptive error messages on failure
  2. expect.extend custom matchers support .not negation modifier
  3. expect.extend registers asynchronous custom matchers returning Promises that resolve with pass and failure message
  4. expect supports asymmetric matchers objectContaining, arrayContaining, stringContaining, stringMatching, and any with toEqual
  5. expect.addEqualityTesters registers custom equality comparators for deep equality checks
  6. expect.getState and expect.setState manage expectation context state
  7. expect.assertions and expect.hasAssertions track executed assertion count
  8. expect supports resolves and rejects promise assertion modifiers
