it([name][, options][, fn])

  • name <string> 测试的名称,报告测试结果时显示。 默认值: The name fn 的属性,如果 fn 没有名称,则为 '<anonymous>'
  • options <Object> 套件的配置选项。 支持与 test([name][, options][, fn]) 相同的选项。
  • fn <Function> | <AsyncFunction> 被测试的函数。 如果测试使用回调,则回调函数作为参数传入。 默认值: 无操作的函数。
  • 返回: undefined

it() 函数是从 node:test 模块导入的值。 每次调用此函数都会在 TAP 输出中创建一个测试点。

  • name <string> The name of the test, which is displayed when reporting test results. Default: The name property of fn, or '<anonymous>' if fn does not have a name.
  • options <Object> Configuration options for the suite. supports the same options as test([name][, options][, fn]).
  • fn <Function> | <AsyncFunction> The function under test. If the test uses callbacks, the callback function is passed as an argument. Default: A no-op function.
  • Returns: undefined.

The it() function is the value imported from the node:test module. Each invocation of this function results in the creation of a test point in the TAP output.
