<div class="ace-line gutter-author-p-199106 emptyGutter"><span class="author-p-199106">How do we apply these principles at Bonusbox? For Bonusbox, the first two principles liberate us from the constraints and costs of a lot of traditional QA behaviors. But principles 3 and 7 force us to regularly re-evaluate our practices (or perhaps, "anti-practices"), as the company, and the product continues to grow and mature. Now, on to the specifics!</span></div>

|

<div class="ace-line gutter-author-p-199106 emptyGutter"><span class="author-p-199106">There are a number of testing practices at Bonusbox, that at first glance, might make us appear to be what used to be called "cowboy coders". Nothing could be further from the truth. There is a method to this madness. However, it's quite true that this method runs directly counter to a number of ancient "industry standards" when it comes to QA as a role, and testing as a practice. Here are the 4 most obvious ones:</span></div>

<div class="ace-line gutter-author-p-199106 emptyGutter"><span class="author-p-199106 i"><i>Think Outside The Black Box - </i></span><span class="author-p-199106">To test at Bonusbox, you need to understand Rails and object oriented concepts the way a dev understands them. You need to be able to do everything a dev can do, with the possible exception of actually writing his code. The days of requirements checklists, and hand-testing an opaque user interface are long gone. To add value to the team, you need to be able to identify the source of problems, including employing whatever technical tools are necessary to do that, even to the point of being able to fix them yourself.</span></div>

In order to execute successfully on continuous deployment, the tester does his work from the same basic environment the developer does: his desktop. Anything that requires external resources that cannot be duplicated or properly mocked, will get tested directly in production. For such cases, breaks will not be backed out unless they're completely irreparable. Instead, they are fixed immediately. </span></div>

This is simply untenable in an environment where features change shape and size almost hourly, as they make their way through the development process of a lean startup. Testers must be able to stay on top of this changing landscape, by staying connected to the code, and to design and development discussions in Trello.</span></div>

Bug counts, feature rejections, and defects passed into production, were all metrics that gauged his competency. He was something of a gatekeeper, standing guard over the business owner's anxiety. Today, the situation is almost entirely the opposite. The QA is a free agent, a special forces commando. He is far less interested in completely sealing off borders, than he is in tracking down and pacifying threats on their own turf. He moves from team to team, working to help them get to deployment as quickly as possible, but also </span><span class="author-p-199106 i"><i>as cleanly as possible</i></span><span class="author-p-199106">. </span></div>

<div class="ace-line gutter-author-p-199106 emptyGutter"><span class="author-p-199106">As you've probably intuited already from the above, </span><span class="author-p-199106 i"><i>good communications</i></span><span class="author-p-199106"> and </span><span class="author-p-199106 i"><i>good relationships</i></span><span class="author-p-199106"> are key to the success of the modern QA Engineer. Though this is listed at the bottom, it is probably the most important feature of QA at Bonusbox. The QA must be capable of negotiating difficult conflicts and analyzing complex problems dispassionately, and he must be willing to communicate his findings with both developers and product managers, in their own language. </span></div>

I've always welcomed testers and QA people with an engineering focus to take some time to understand the code that underlies the systems they are testing, and there's no better way to learn a system than to fix bugs in a project.</span></li></ul></div>

Having QA fix bugs without the involvement of a developer or someone in project management could cause a range of problems. Maybe development has decided to delay the implementation of a feature because the business hasn't fully elaborated on a requirement? Maybe a particular bug is present because a developer is waiting for clarification? "</span></li></ul></div>
