Why Do I Have to Test Your Shit? (The 5-Minute Sniff Test)

If you can’t spend 5 minutes testing your work, then don’t make me.

I’ve spent 18 years in the software engineering industry, and have been called a programmer, then a developer, and now a software engineer — next is “delivery demon,” mark my words. In that time, I’ve tested my fair share of code. I’ve worked as a part-time tester, tested code I’ve written, ran QA groups, and poked my nose into systems I shouldn’t have.

The 5-Minute Sniff Test

As a Software Engineer, you chose a career building great software. You love solving fun and interesting problems using the latest frameworks, the coolest algorithms, and rainbows & unicorns. On a daily basis, “You Crush It!” However, all that screeches to a halt if you have to stumble through the muck of poorly defined (sometimes incomprehensible) requirements just to get to the heart of the problem.

A Lesson from the Front

That “I want to crawl under a rock” feeling

My team and I once built an awesome new feature in our iPad app that was technically challenging and had the coolest design, and I was very proud of the work we did. It rocked and we had crushed it!

Take Care of Your Stuff

Don’t make someone else pick up after you.

Typically I’ll hear software engineers argue that it’s too hard to change their mindset from coding to testing.

How To Perform Your Own 5-Minute Sniff Test

The 5-Minute Sniff Test is the first line of defense against the “I will just hand over anything” mentality.

  • Check Your Unit Tests — 30 Seconds: Do all the unit tests pass, and is there full code coverage? You can’t test everything by hand, so automated unit tests are vital for code quality. The 30 seconds allotted isn’t to create the unit test, but just to verify they pass. You should also consider failing the build if the unit tests don’t pass, which would allow more time for the obvious.
  • The Obvious — 190 Seconds: Did you test all the obvious cases? For example, if the pressed button should cause unicorns to dance across the screen, be sure to test if pressing the button actually makes unicorns dance across the screen. Do I get any errors in the logs, do rainbows show even though that isn’t part of the requirements (although it should be, because that would be awesome), and what happens if I double click the button? Review the requirements and make sure everything adds up. For example, did you catch that the total number of seconds listed here equals 310 instead of 300 seconds? Let’s correct “The Obvious” to 180 seconds.

Looking Ahead

In his book “Blink,” Malcolm Gladwell relates the story of interviewers making snap judgements about the quality of a candidate within the first five seconds of meeting. The interviewer continues to subconsciously reinforce their initial impression by subjectively weighing the candidate’s answers towards their bias.

  • It is more Efficient with everyone’s time.
