simplecov:提取覆盖率

Question

我这样跑得太简单了

# 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96.77号保存到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

这有点麻烦，但这才是对我有用的。(它在bash中，调用生成覆盖率的命令，并在文件中有%签名.)

<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
