Hi,

I have an options hash map as a run method's second parameter

I am currently doing this

run File.join(File.dirname(__FILE__), "../projects/#{filename}", {"-
fh:" => "C:/rspec_reports/#{filename}.htm"})

But I am recieving this error

`join': can't convert Hash into String (TypeError)

Could anyone give me the correct syntax please?

Try this:
run File.join(File.dirname(__FILE__), "../projects/#{filename}", "-
fh: => C:/rspec_reports/#{filename}.htm")

Aidy, you call the run method with only one parameter, the result of
File.join. The hash is the third parameter to File.join.
