SimpleCov:提取覆盖率百分比

Question

>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，或者除了打印这个

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 env 变量或文件中。

Answer 1

到目前为止，

我想出了

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

Answer 2

这有点混乱，但它对我有用。（这是在 bash 中，调用生成覆盖率的命令，并在文件中具有 % 符号...

<command>  | tee -a log/coverage.log
coverage_string="$(grep "Coverage report generated" log/coverage.log)"
[[ "$coverage_string" =~ ([[:digit:]]+.[[:digit:]]+%) ]] && echo ${BASH_REMATCH[1]} > percent.txt
