I’m trying to create an xml runner to make a result report of Rails

  • 0

I’m trying to create an xml runner to make a result report of Rails unit testing. Here is a code I have:

require 'test/unit'
require 'test/unit/ui/console/testrunner'

class FastFailRunner < Test::Unit::UI::Console::TestRunner
  def add_fault(fault)
    @faults << fault
    nl
    output("%3d) %s" % [@faults.length, fault.long_display])
    output("--")
    @already_outputted = true
  end

  def finished(elapsed_time)
    nl
    output("Finished in #{elapsed_time} seconds.")
    nl
    output(@result)
  end
end

Test::Unit::AutoRunner::RUNNERS[:fastfail] = proc do |r|
  FastFailRunner
end

When I run it as TESTOPTS="/home/alex/RubymineProjects/app2/test/unit/runner.rb --runner=xml" rake test

… I get an error (pretty weird error)

/home/alex/.rvm/gems/ruby-1.9.3-p194@global/gems/rake-0.9.2.2/lib/rake/ext/module.rb:36:in `const_missing': uninitialized constant Test::Unit::UI::XML (NameError)

I tried to require test/unit/ui/xml/testrunner.rb but no luck.
Any thoughts?

    If you are in Ruby 1.8.7 you can say:

    require 'test/unit/ui/console/testrunner'
p Test::Unit::UI::Console::TestRunner # => no problem

    (There is no such file as test/unit/ui/xml/testrunner.rb so I’m not sure what you were up to there.)

    Look in the docs in test/unit.rb, there’s actually sample code showing you how to do this require: http://www.ruby-doc.org/stdlib-1.8.7/libdoc/test/unit/rdoc/Test/Unit.html.

    However, the problem is that you are in Ruby 1.9.3. There is no /test/unit in Ruby 1.9.3! Well, there is, but it’s just a compatibility layer for basic tests; there is certainly no test/unit/ui/console/testrunner, and no module/class Test::Unit::UI::Console::TestRunner.

    Instead, there’s minitest. You can read the docs on minitest to see how to make a test runner. http://docs.seattlerb.org/minitest/
