如何将现有的伊斯坦布尔 json 文件转换为 html

Question

我想istanbul将从客户端获取的 JSON 格式的覆盖率报告文件转换为 html 格式。目前我正在使用remap-istanbul这个，但实际上那个特定的工具旨在为最初用不同语言（如打字稿）编写的代码重新映射覆​​盖率数据。

所以我想是否有更方便的方法来做同样的事情

使用istanbul report html现有的从JSON覆盖数据转换为HTML：

istanbul report html

默认情况下，上述内容在当前目录（及其子目录）中查找以“coverage”开头并以“.json”结尾的任何文件，并将 HTML 报告输出到该./coverage/目录。

要将特定文件转换为特定目录：

istanbul report --include path/to/my-coverage-file.json --dir my-coverage-dir html

另一种仅从特定目录（例如 中的所有 JSON 文件path/to）读取覆盖率报告的方法如下，使用--root选项：

istanbul report --root path/to --include=*.json --dir my-coverage-dir html

使用istanbul help report可查看更多选项（以下是伊斯坦布尔0.4.5生成）：

Usage: istanbul report <options> [ <format> ... ]

Options are:

      --config <path-to-config>
              the configuration file to use, defaults to .istanbul.yml

      --root <input-directory>
              The input root directory for finding coverage files

      --dir <report-directory>
              The output directory where files will be written. This defaults
              to ./coverage/

      --include <glob>
              The glob pattern to select one or more coverage files, defaults
              to **/coverage*.json

      --verbose, -v
              verbose mode


<format> is one of 
      clover  XML coverage report that can be consumed by the clover tool
      cobertura

      html    Navigable HTML coverage report for every file and directory
      json    prints the coverage object as JSON to a file
      json-summary

      lcov    combined lcovonly and html report that generates an lcov.info
              file as well as HTML
      lcovonly
              lcov coverage report that can be consumed by the lcov tool
      none    Does nothing. Useful to override default behavior and suppress
              reporting entirely
      teamcity
              report with system messages that can be interpreted with TeamCity
      text    text report that prints a coverage line for every file, typically
              to console
      text-lcov
              lcov coverage report that can be consumed by the lcov tool
      text-summary
              text report that prints a coverage summary across all files,
              typically to console

 Default format is lcov unless otherwise specified in the config file. In
 addition you can tweak the file names for various reports using the config
 file. Type `istanbul help config` to see what can be tweaked.
