我试图在Rails 3应用程序上运行metric_fu一切都很好，除了rcov我已经配置了RSpec，我的测试遵循spec/**/*.rb格式，并在RSpec中运行良好但是，尝试使用rcov检查覆盖率时，我得到以下错误：
** Running the specs/tests in the [test] environment
No file to analyze was found. All the files loaded by rcov matched one of the
following expressions, and were thus ignored:
[/\A\/Users\/Eric\/\.rvm\/rubies\/ruby\-1\.8\.7\-p299\/lib/,
/\btc_[^.]*.rb/,
/_test\.rb\z/,
/\btest\//,
/\bvendor\//,
/\A\/Users\/Eric\/\.rvm\/gems\/ruby\-1\.8\.7\-p299@-backend\/gems\/rcov\-0\.9\.8\/lib\/rcov\/formatters\/base_formatter\.rb\z/,
/\bvendor\//,
/\bconfig\//,
/\benvironment\//,
/\/gems\//,
/\/Library\//,
/\/usr\//,
/spec/]
You can solve this by doing one or more of the following:
* rename the files not to be ignored so they don't match the above regexps
* use --include-file to give a list of patterns for files not to be ignored
* use --exclude-only to give the new list of regexps to match against
* structure your code as follows:
test/test_*.rb for the test cases
lib/**/*.rb for the target source code whose coverage you want
making sure that the test/test_*.rb files are loading from lib/, e.g. by
using the -Ilib command-line argument, adding
$:.unshift File.join(File.dirname(__FILE__), "..", "lib")
to test/test_*.rb, or running rcov via a Rakefile (read the RDoc
documentation or README.rake in the source distribution).

当我直接运行rcov时，问题的一部分似乎是rcov没有在我的specs中正确加载spec_helper，这是“require‘spec_helper’”所必需的。
关于如何解决这个问题有什么帮助吗谢谢。
最佳答案
在metric fu配置中添加“-ispec”可以解决这个问题。
关于ruby - 度量标准Fu:RCov无法加载spec_helper，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/3255621/
