我有一个Angular 项目，我想用内置的单元测试工具(Karma)和 cypress 来测试它.我的任务是将两者的code coverage reports合并.
我已成功创建覆盖配置.输出成功地与nyc merge合并:然而，这些数字并不相加.
从package.json起的相关版本:
"@angular/core": "^16.0.3",
"cypress": "^12.13.0",
"istanbul-lib-coverage": "^3.2.0",
"@cypress/code-coverage": "^3.11.0",
"@cypress/webpack-preprocessor": "^5.17.1",
"@istanbuljs/nyc-config-typescript": "^1.0.2",
"@jsdevtools/coverage-istanbul-loader": "^3.0.5",
"karma": "^6.4.2",
"karma-coverage": "^2.2.0",
"nyc": "^15.1.0",
以下是Karma年度覆盖率报告结果中的一个文件示例:

运行nyc report --reporter=lcov --reporter=text-summary会产生以下结果:
这会是什么问题呢？我try 了这里的https://github.com/istanbuljs/nyc/issues/1302个建议中的一些，但都没有奏效.迁移到早期版本的ISTAMBUL(例如14.1)会产生胡言乱语的数据(它不会解析我的Typescript 文件).
Update:个 下面是我用来生成输出的命令:
- 首先，我验证我在
karma和cypress文件夹中是否有现有的报告. - 命令:
"coverage-merge-and-report": "mkdir -p coverage/toMerge && cp coverage/karma/coverage-final.json coverage/toMerge/ && cp coverage/cypress/coverage-final.json coverage/toMerge/coverage-final-cypress.json && nyc merge coverage/toMerge coverage/toMerge/merged.json && npx nyc report --reporter=lcov --reporter=text-summary --temp-dir=coverage/toMerge --report-dir=coverage/merged-report"
The problem with it was with the final part: npx nyc report --reporter=lcov --reporter=text-summary --report-dir=... scans for the .nyc_output folder I belive, and the reportes is not right either.
我将其更改为:npx nyc report --reporter=html --reporter=text-summary -t coverage/test --report-dir=...，现在它产生了一个正确的答案.
