node.js - jest-cli代码覆盖率仅显示零百分比

Question

出于某种原因，在我的新项目中，我的测试覆盖率始终显示为0%，即使有测试并且它们显然正在运行。

Test Suites: 3 failed, 4 passed, 7 total
Tests:       4 failed, 21 passed, 25 total
Snapshots:   0 total
Time:        1.849s, estimated 2s
Ran all test suites.

=============================== Coverage summary ===============================
Statements   : 0% ( 0/663 )
Branches     : 0% ( 0/285 )
Functions    : 0% ( 0/117 )
Lines        : 0% ( 0/496 )
================================================================================

我的配置有问题吗？我的测试文件在 __tests__中，这里是我的配置文件中的jest配置。

 "jest": 

{
      "automock": true,
      "collectCoverage": true,
      "collectCoverageFrom": [                                                                                                                                                                                                                                                                                                                                          
        "src/js/**/*.js"
      ],
      "coverageReporters": [
        "lcov",
        "text-summary"
      ],
      "coveragePathIgnorePatterns": [
        "<rootDir>/node_modules/"
      ],
      "unmockedModulePathPatterns": [
        "/node_modules/keymirror",
        "serialport"
      ]
}

把"src/js/**/*.js"改成"src/js/**/**.js"有帮助吗？（在.js中添加第二个星号）
