覆盖率无法生成coverage.lcov

Question

我很难生成coverage.lcov

在monorepo中运行github action (使用梅洛斯)

我认为这个问题可能是由覆盖范围引起的，但也有可能

我错过了一些零钱(过去的一年我很忙)

这是melos.yaml的相关部分

  test:format:
    run: melos exec -c 1 -- format_coverage --lcov --check-ignore  --in=coverage --out=coverage.lcov --packages=.packages --report-on=lib
    description: Format Dart tests' coverage data
    select-package:
      flutter: false
      dir-exists: test

这是失败的coverage命令

format_coverage --lcov --check-ignore  --in=coverage --out=coverage.lcov --packages=.packages --report-on=lib

用这些原木

生成coverage.lcov的正确命令是什么？

这是日志

Answer 1

结果显示了命令

dart test --coverage="coverage"

和

flutter test --coverage

已经输出了一个lcov.info文件

(我敢肯定，情况并非总是如此)

所以根本不需要运行format_coverage

( codecov/codecov-action@v3很好地理解了这一点)

Answer 2

拜托，试试这个

dart pub global run coverage:format_coverage --packages=.dart_tool/package_config.json --report-on=lib --lcov -i coverage -o coverage/lcov.info

参见详细信息这里。
