'test:coverage' 事件

• data <Object>
  • summary <Object> 包含覆盖率报告的对象。
    • files <Array> 单个文件的一系列覆盖率报告。 每个报告都是具有以下架构的对象：
      • path <string> 文件的绝对路径。
      • totalLineCount <number> 总行数。
      • totalBranchCount <number> 分支总数。
      • totalFunctionCount <number> 函数总数。
      • coveredLineCount <number> 被覆盖的行数。
      • coveredBranchCount <number> 覆盖的分支数。
      • coveredFunctionCount <number> 覆盖函数的个数。
      • coveredLinePercent <number> 覆盖行的百分比。
      • coveredBranchPercent <number> 覆盖的分支百分比。
      • coveredFunctionPercent <number> 覆盖的函数百分比。
      • uncoveredLineNumbers <Array> 一个整数数组，表示未覆盖的行号。
    • totals <Object> 包含所有文件覆盖率摘要的对象。
      • totalLineCount <number> 总行数。
      • totalBranchCount <number> 分支总数。
      • totalFunctionCount <number> 函数总数。
      • coveredLineCount <number> 被覆盖的行数。
      • coveredBranchCount <number> 覆盖的分支数。
      • coveredFunctionCount <number> 覆盖函数的个数。
      • coveredLinePercent <number> 覆盖行的百分比。
      • coveredBranchPercent <number> 覆盖的分支百分比。
      • coveredFunctionPercent <number> 覆盖的函数百分比。
    • workingDirectory <string> 代码覆盖开始时的工作目录。 这对于显示相对路径名很有用，以防测试更改了 Node.js 进程的工作目录。
  • nesting <number> 测试的嵌套级别。

启用代码覆盖率并且所有测试都已完成时发出。

• data <Object>
  • summary <Object> An object containing the coverage report.
    • files <Array> An array of coverage reports for individual files. Each report is an object with the following schema:
      • path <string> The absolute path of the file.
      • totalLineCount <number> The total number of lines.
      • totalBranchCount <number> The total number of branches.
      • totalFunctionCount <number> The total number of functions.
      • coveredLineCount <number> The number of covered lines.
      • coveredBranchCount <number> The number of covered branches.
      • coveredFunctionCount <number> The number of covered functions.
      • coveredLinePercent <number> The percentage of lines covered.
      • coveredBranchPercent <number> The percentage of branches covered.
      • coveredFunctionPercent <number> The percentage of functions covered.
      • uncoveredLineNumbers <Array> An array of integers representing line numbers that are uncovered.
    • totals <Object> An object containing a summary of coverage for all files.
      • totalLineCount <number> The total number of lines.
      • totalBranchCount <number> The total number of branches.
      • totalFunctionCount <number> The total number of functions.
      • coveredLineCount <number> The number of covered lines.
      • coveredBranchCount <number> The number of covered branches.
      • coveredFunctionCount <number> The number of covered functions.
      • coveredLinePercent <number> The percentage of lines covered.
      • coveredBranchPercent <number> The percentage of branches covered.
      • coveredFunctionPercent <number> The percentage of functions covered.
    • workingDirectory <string> The working directory when code coverage began. This is useful for displaying relative path names in case the tests changed the working directory of the Node.js process.
  • nesting <number> The nesting level of the test.

Emitted when code coverage is enabled and all tests have completed.
