simplecov 报告覆盖 0.0%

simplecov report 0.0% covered

我正在开发一个小插件,其中包括 simplecov。

在我的 gem 文件中有一行:

gem 'simplecov', :require => false, :group => :test

在我的测试文件中,我输入了行 require "projectname/devuntil/rspec/spec_helper" 在文件的最顶部。

在我的 spec_helper.rb 文件中,我在文件顶部添加了 simplecov

if ENV['COVERAGE']
  require 'simplecov'
  require 'coveralls'

  puts "require simplecov and coveralls"
  SimpleCov.formatter = SimpleCov::Formatter::MultiFormatter[
    SimpleCov::Formatter::HTMLFormatter,
    Coveralls::SimpleCov::Formatter
  ]

  SimpleCov.start do
    add_filter 'spec/'
    add_filter 'vendor/'
    puts "Start simple coverage"
  end
end

当我尝试 运行 使用命令 COVERAGE=true bundle exec rspec 进行测试时,它显示:

[root@node1 logstash-input-imap]# COVERAGE=true bundle exec rspec
Coverage may be inaccurate; set the "--debug" command line option, or do JRUBY_OPTS="--debug" or set the "debug.fullTrace=true" option in your .jrubyrc

虽然调用了我的函数,但它仍然显示覆盖了 0.0%。
这里可能有什么问题以及如何解决?谢谢

您可以尝试在您的项目根目录中使用以下内容创建 .jrubyrc:

cli.debug=真

debug.fullTrace=真
