        parse: (output) => output,
        print: process.stdout.write.bind(process.stdout)
    }
});
sr.run();

Testing executable scripts:
  Testing: testr.js
   - script exists
   - 1. "$ node testr.js --answer=hello --ack=hello" should be 100 [95 ms]
   - 2. "$ node testr.js --answer=hello --ack=" hello "" should be 100 [91 ms]
   * 3. "$ node testr.js --answer=hello --ack=hellO" should be 20 but returned 0 [92 ms]
   - 4. "$ node testr.js --answer=hello --ack=hellO --i" should be 100 [94 ms]
   ! 5. "$ node testr.js --answer=hello" should be 0 but threw an exception
  Testing: return.js
   * script exists
   * 1. "$ node return.js --answer=100" should be 100
   * 2. "$ node return.js --answer=-20" should be -20
  Testing: time.js
   - script exists
   - 1. "$ node time.js" should be 100 [92 ms]
