“The developers are ignoring our input!”
“Tester? Eh, guess he wasn’t good enough to get a job as a developer.”
Ever heard that before?
One of the keys to good QA is to have a team with a high level of trust. Actually, that’s one of the keys to good anything, when a team is involved. But right now we’re talking about testing.
Trust, of course, has to be earned. And it has to go both ways. So what do the testers need to do to earn trust from the developers, and what do the developers have to do to earn the testers’ trust?
Testers
Do a good job
Know the product. Know the business. Know the code base. Know the history. Know the context. Understand how all of these fit together.
There is no excuse for a tester not to know just as much about the product as the developers do. Testing is often viewed as the “easier” job in software development, one that doesn’t require as much skill as coding. That is simply not true. As a tester, you need to be deeply technical, highly logical and strongly creative, even if you never write a line of code. Expect nothing less from your own work than you would expect from the best developer on the team.
Even if you get everything else in this blog post right, nobody will trust you if you are incompetent.
Communicate clearly
One of the most important tasks of a tester is to provide information about bugs we have found. There is almost nothing a developer appreciates more than a well-written bug report. On the other hand, there is almost nothing that irritates a developer more than a badly written bug report.
If you aim to build trust between yourself and your developer, which type of bug report should you choose to write? Exactly.
(How to write a good bug report is a blog topic of its own – I will return to it)
Be reasonable and pragmatic
As testers, bugs are important to us. Especially the ones we just found, or the ones we worked really hard to find. It can be annoying when our bug reports are wontfixed or postponed to next release. It can be really annoying when the release goes out the door and you know about all the bugs that haven’t been fixed.
Deadline’s going to happen, though, and it won’t help you to be grumpy about it. Do what you can to inform the relevant stakeholders about the quality and the risk, and be reasonable about it. If you make a huge fuss about every minor issue, everyone will ignore you when you found the disaster that really needs to stop the release.
Developers
Do a good job
Don’t code in a way that causes stupid bugs. Regressions are stupid bugs caused by unmaintainable code with low modularity and no unit test coverage.
Testers don’t like stupid bugs. It makes them have to repeat the work they did last week just because they can’t be reasonably confident that the bugfix you did in one part of the code didn’t break anything somewhere else.
Even if you get everything else in this blog post right, nobody will trust you if you are incompetent.
Don’t assume it’s not a bug
The type of developer that annoys testers the most are those who always assume a reported problem is not a bug – and especially not a bug in their part of the code – until it has been proved to them beyond all doubt. Those who instinctively close all bug reports from junior personnel without even reading the details, and will only grudgingly accept reopening it after involvement from the junior tester’s managers.
Sure, some bug reports will turn out not to be actual bugs. If you get a lot of these from the test team or a specific tester, you should bring it up with them. In all likelihood, though, if there’s a bug report, there is an actual problem somewhere, even if you don’t see it at first glance. As a developer, you are responsible for the quality of the product, and it should be expected of you to make an effort to improve it. A dismissive attitude towards the testers is the surest way to get less help with that.
Communicate clearly
A tester almost always works with too little information. Tell them what you did, how you did it, what kind of side-effects it could have, what the risks are, how to configure it, and they will be forever grateful.
Your ten minutes of writing up this as you close your development ticket will save the tester hours, potentially days, of figuring it out on their own. The tech writers will be happy too.
Take an active part in quality improvement
Ask the testers how the product can be made more testable. Add test hooks where needed. Create test apps. Do some basic testing of your own products before sending them off to the testers. Refactor. Make downpayments on technical debt. Make use of the testers’ expertise to make your own work better.
