Developers – Stop Doing QA's Job

Unit Testing can solve the problem

We've all been there - it's Friday night, 11PM and the system you just deployed doesn't work. There's a bug. Your manager just hung up. You phone your friends to tell them that you're not going out tonight. You start thinking: Why didn't QA catch that. Now management is going to add more QA staff, give them more budget, and there's going to be a zero bug tolerance policy once again.

There is a way out of this problem. Could it actually be unit testing? I had the good fortune to visit two development teams in the same company and compare firsthand the experience of teams that might prove this assumption.

Two years ago, the teams diverged on different paths.

"Unit testing?" said the first team leader. "We know it is going to be hard. But we heard that it's likely to provide lots of benefits: cleaner code, fewer bugs, quicker development cycle... and our whole development team has been begging for this. QA also spends significantly less time finding bugs. Manual testing may have taken too long but that's gone the way of the dodo. We're going to have to get management on board. "

"We've heard that unit testing is a good practice but we are under a lot of pressure. I'm sure that it will postpone our release date," said the second team leader. "Let's do it after the release. "

The first team convinced the management to give 20% of its time to unit testing and continued to learn, improve, and were persistent in writing unit tests.

The second team kept on postponing unit testing ‘til after the "next release."

I went back to visit the teams recently, to see how they are getting along. It was eye-opening.

I had a great discussion with both teams.

The team that learned about unit testing and started testing (using Typemock Isolator) kept on speaking highly of their results and gave the unit testing love as they were overwhelmed with joy over their processes and tools.


Their software release cycle (developers and QA) is much shorter (25%-33%) than the other team. Software is released quicker. The team has stayed relatively intact as engineers prefer to work in environments with automated unit testing.

QA is relatively happy. Compared to the other team, they focus on real usage issues rather than simply getting the application to work. They find less critical bugs and the bugs they find are significantly less severe than the other team. The developers are more confident in their code, allowing them to make changes quickly, without introducing bugs.

The developers are consistently adding functionality. Of course bugs still creep in even with unit testing. However, the few bugs found by QA aren't anything to be ashamed of - both sides are happier and trust among the teams has increased. Management is also happier with the quality of the software - after all, fewer customer complaints means reaching the business goals.

What about the second team that didn't unit test?

The team that didn't start unit testing kept talking about how they would like to do unit tests and the developers are ashamed that they never started.

The team members were having problems. Pressure, delayed releases, and management were on the team's back because of too many bugs. That is why the management decided on a zero bug tolerance policy again. This meant that the team had to build a QA-style environment and had to test the system manually before sending the application to the QA team. Practically, they were doing QA's job in order to lower the bugs sent to the QA.

The developers are not happy. Their focus turned from adding more features to get the bugs to QA down. They do this by manual ‘QA style' testing, constantly running the debugger, engaging in time-consuming deployment and manual testing for every small feature instead of developer-style unit testing ... and they know it. This makes the development cycle longer and no one is happy as they are all overworked. Caffeine and foosball doesn't compensate for sleepless nights and endless debugging.

QA is saddled with bugs and is working overtime to bring them down and is requesting more and more money in their budget to get the bugs ironed out....tired of fighting with the developers and management about the number of bugs and consistently delayed release due to the incessant back and forth between the two teams.

By not unit testing, the team is doing their work plus QA's work: they are developing their software, plus testing their code

It is obvious that the team that was persistent with unit testing, and went through the ropes and hardship of learning how to do it correctly, had the upper hand. They improved their coding skills, were energized by their coverage and had a better time-to-market. The other team, well they starting to do the QA's job too.

Apps and devices shouldn't stop working when there's limited or no network connectivity. Learn how to bring data stored in a cloud database to the edge of the network (and back again) whenever an Internet connection is available. In his session at 17th Cloud Expo, Bradley Holt, Developer Advocate at IBM Cloud Data Services, will demonstrate techniques for replicating cloud databases with devices in order to build offline-first mobile or Internet of Things (IoT) apps that can provide a better, faster user experience, both offline and online. The focus of this talk will be on IBM Cloudant, Apa...
As more and more data is generated from a variety of connected devices, the need to get insights from this data and predict future behavior and trends is increasingly essential for businesses. Real-time stream processing is needed in a variety of different industries such as Manufacturing, Oil and Gas, Automobile, Finance, Online Retail, Smart Grids, and Healthcare. Azure Stream Analytics is a fully managed distributed stream computation service that provides low latency, scalable processing of streaming data in the cloud with an enterprise grade SLA. It features built-in integration with Azur...
As enterprises capture more and more data of all types – structured, semi-structured, and unstructured – data discovery requirements for business intelligence (BI), Big Data, and predictive analytics initiatives grow more complex. A company’s ability to become data-driven and compete on analytics depends on the speed with which it can provision their analytics applications with all relevant information. The task of finding data has traditionally resided with IT, but now organizations increasingly turn towards data source discovery tools to find the right data, in context, for business users, d...

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud without worrying about any lock-in fears. In fact by having standard APIs for IaaS would help PaaS expl...

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...
