Ruby simplecov：提取覆盖率百分比

我像这样运行simplecov

# test/test_helper.rb
require 'simplecov'
SimpleCov.start do
  add_filter "/test/"
  coverage_dir "/tmp/coverage/"
end

相反，或者除了打印此

Coverage report generated for Unit Tests to /tmp/coverage. 30 / 31 LOC (96.77%) covered.

如何告诉ruby/simplecov将数字96.77保存到一个env变量或文件中。

到目前为止，我想到了

SimpleCov.at_exit do
  IO.write('/tmp/result_tests_coverage', 'work-in-progress')
end

到目前为止，我想出了

SimpleCov.at_exit do
  IO.write('/tmp/result_tests_coverage', 'work-in-progress')
end

这有点乱七八糟，但这对我来说是可行的。（这在bash中，调用生成覆盖率的命令，文件中有%符号…）

| tee-a log/coverage.log
coverage_string=“$（grep“coverage report generated”log/coverage.log）”
[[“$coverage\u string”=~（[[：digit:]+\.[：digit:]+\%]）和&echo${BASH\u REMATCH[1]}>percent.txt
