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

执行证据

声明的环境与签名的运行分开呈现，你可以看到这个样本究竟运行了什么、在哪里运行。

契约

  1. matcherHint formats standard matcher invocation headers with expected and received labels
  2. matcherHint supports options including isNot, promise, and comment modifiers
  3. printExpected formats expected values with quotes and syntax formatting
  4. printReceived formats received values with quotes and syntax formatting
  5. printWithType displays the type and formatted value of an argument
  6. diff computes and returns a unified string diff between expected and received values
  7. stringify serializes JavaScript values cleanly into string representation
  8. matcherErrorMessage formats standard matcher failure messages with hints and explanations
  9. ensureActualIsNumber validates received value is numeric and throws formatted error otherwise
  10. ensureExpectedIsNumber validates expected value is numeric and throws formatted error otherwise
  11. ensureNoExpected verifies matcher does not receive an expected argument
  12. pluralize formats countable noun singular and plural forms based on count
  13. getLabelPrinter creates formatted and aligned label printers for matcher outputs
