How to save Cucumber test results to a file

Question

I have some Cucumber tests that can be run from console with

rake cucumber

Is there a command line option to store test results to a text file?

Answer 1

Either

• Run cucumber directly and use -o. From cucumber --help:

  -o, --out [FILE|DIR]
      Write output to a file/directory instead of STDOUT. This option
      applies to the previously specified --format, or the
      default format if no format is specified. Check the specific
      formatter's docs to see whether to pass a file or a dir.
  

• Run rake with CUCUMBER_OPTS="-o whateverfile", i.e.

  CUCUMBER_OPTS="-o whateverfile" rake cucumber # assuming you're using a Bourne family shell
  

  or

  rake CUCUMBER_OPTS="-o whateverfile" cucumber
  

• Edit lib/tasks/cucumber.rake and add

  t.cucumber_ops = '-o whateverfile'
  

  to one or more of the Cucumber::Rake::Tasks

• Or just redirect the output of the cucumber command yourself:

  cucumber > whateverfile
  

-o is a little different than redirecting: it always prints the "progress" output to the screen. If you don't specify a format it puts the default "pretty" format in the file. If you do (e.g. cucumber -f html -o whateverfile) it puts the format you specify in the file.

In case it matters, I'm using Ruby Cucumber 2.3.2.
