Do You Still Have QA Engineers on Your Team? | by Manvik Kathuria | May, 2022

Exploring the function of high quality assurance in modern-day software program growth

Software program Testing Assist defines high quality as “one thing that meets the necessity and expectation” and assurance as “a optimistic declaration of confidence given a couple of services or products. Once we mix the 2, we get a wonderful definition: “QA is a optimistic declaration concerning the high quality of a service or a product that offers confidence.”

In accordance with SWEBOK, “Software program high quality assurance (SQA) is a method and apply of monitoring the software program engineering processes and strategies utilized in a venture to make sure correct high quality of the software program.”

Software program high quality assurance has at all times been an integral a part of SDLC. The idea of testing and QA has stood the take a look at of time because it transitioned from sequential (waterfall) to iterative (agile, Kanban) growth fashion.

All of us agree that software program high quality is as necessary as supply, and you shouldn’t compromise on it. The most effective and hottest services supply wonderful high quality. They stand aside from the competitors, which suggests you ship code with no defects, efficiency, or UI points. A very good high quality product/service builds belief with clients and results in good critiques and a willingness to pay for it.

There’s a long-running debate on the distinction between a QA engineer and Take a look at engineer. I’m not going to enter this as a result of every organisation is totally different. I’ve seen this used interchangeably, with folks masking each roles. For this text, I do not differentiate, and the factors talked about beneath can be related for each.

Conventional software program growth and the age of handbook testing

Tasks was once waterfall, with a set of necessities gathered upfront. Each change was frowned upon with all of the actions preplanned. The testers would take the necessities, write take a look at instances, and look forward to the event workforce to complete coding. As soon as the event part was over, they might execute the assessments (primarily handbook). The tester would discover bugs, get them fastened, retest, and the method goes on to fulfill the required ranges of high quality.

Most significantly, there was a transparent separation within the function and tasks of a developer and a tester. This divide creates the impression that high quality is a tester’s accountability. One of many causes for this was the testing course of. Because it was principally handbook, it required somebody to totally dedicate their effort and time to check the software program and assess it throughout the boundary of the captured necessities.

The handbook course of is sluggish, error-prone, unscalable, costly, and depends closely on the tester’s ability. Even with the take a look at instances written and scripted, it is determined by somebody sitting on the desk urgent buttons and capturing outcomes. This method requires you to have QA/testers in your workforce consider the standard of your deliverable and stop points in manufacturing.

Fashionable software program growth and the rise of automation testing

With the emergence of agile methodologies, the turnaround time between growth and testing has decreased, calling for elevated collaboration and the necessity to take a look at shortly and reliably. With time, the strains began blurring between builders and testers, and testing shifted within the SDLC.

Succeeding with Agile: Software program Improvement Utilizing Scrum by Mike Cohen

Mike Cohen’s take a look at pyramid exhibits the totally different layers of testing and supplies route on the pace, amount, and kind of assessments at every degree. This idea creates a high quality gate throughout all software program growth roles in essentially the most simplistic method attainable. Although it may not apply to all situations, it makes high quality part of everybody’s function.

“High quality isn’t an act, it’s a behavior.” — Aristotle

High quality is changing into a shared accountability. The workforce that delivers should personal the standard of the product regardless of the person function. This shift of focus has given delivery to the rise of automation. Mixed with the pressure of DevOps, testing is now considerably totally different with the power to check a number of instances a day with out handbook intervention.

Within the age of digitisation and data, computer systems will take over repetitive duties, and testing is one space that has already benefited a lot from it. The consistency, pace, and reliability of automation assessments (particularly regression assessments) considerably cut back the time to check methods, permitting your workforce to deploy a number of instances a month (days too).

I do know your first thought is that if we are able to automate, we are able to eliminate QA as a apply and function. Earlier than you leap forward, let’s analyse take a look at automation. Automated assessments are nice however dumb since they’re programmed to check the identical factor a number of instances. QAs code these assessments after analysing every consumer story’s necessities and acceptance standards.

If you happen to take a look at it from one other perspective, the QAs writing automation code is kind of near builders, besides they work on a unique set of necessities. Ultimately, they’re each writing code to create a system that performs a specific activity.

An space the place automation falls over is exploratory testing. The intelligence, creativity, observations, and understanding a human has are but to be absolutely transmitted to a machine (probably taking place someplace by AI/ML). Do not forget there are nonetheless groups that depend on handbook testing as a result of nature of the venture.

Personally, the function of QA will probably be related, however the strains are getting blurred with builders. Correctly designing automated assessments is as necessary as creating the product/service you might be testing. This exercise requires abilities and information historically within the builders’ panorama.

In case you are a QA and possess this ability, you’ll simply survive (even thrive) throughout this transition. On the intense aspect, with firms pushing to launch shortly and simply, the necessities for QA improve to automate repetitive duties and deploy sooner.

Every organisation has a unique tackle this matter, and they’re proper of their manner. Some have stopped hiring QAs and put the onus on builders to put in writing the automation; others have full-time QAs chargeable for creating automation.

I believe it boils down to at least one factor: are you able to write code? There are many alternatives now and sooner or later if you happen to can. There’ll at all times be roles for testing, though considerably extra for automation than handbook.

Thanks for studying!
