RSpec

RSpec is a testing framework for Ruby.

Enabling XML Output

RSpec can be configured to produce JUnit XML output by installing the rspec_junit_formatter module.

gem install rspec_junit_formatter

Add the formatter to your command line like this:

rspec src --format RspecJunitFormatter

Test Suite Naming

The output file can be set with the --out option like this:

rspec src --format RspecJunitFormatter --out rspec_test.xml

By default, RSpec will include the file attribute in the output XML like this:

<?xml version="1.0" encoding="UTF-8"?>
<testsuite name="rspec" tests="3" skipped="0" failures="1" errors="0">
  <testcase classname="ruby.rspec.spec.calculator_spec" 
            name="Calculator.halve given the number 3 returns 1.5" 
            file="./ruby/rspec/spec/calculator_spec.rb" 
            time="0.010126">
            <failure message="
expected: 1.5
     got: 1

(compared using ==)
" type="RSpec::Expectations::ExpectationNotMetError">Failure/Error: expect(Calculator.halve(3)).to eq(1.5)

  expected: 1.5
       got: 1

  (compared using ==)
./ruby/rspec/spec/calculator_spec.rb:25:in `block (4 levels) in &lt;top (required)&gt;&apos;</failure>
  </testcase>
</testsuite>
