The missing knowledge of testers in modern app development.

The game has changed for testers, they need to extend their basic testing skills when they want to stay valuable. As other team members, testers need to be a full member of the team with the current skill set this isn’t.

While supporting teams for a long time in delivering software I noticed I’m always teaching new ‘test’ team members the same skills. Skills a new team member actually already should have had before entering the team room.

A small list.


Agile knowledge.

Knowledge about agile work in teams is the minimal a test team member should have.

When they fail a basic assessment like the open assessment ( ) I silently start to cry.


Agile is that mainstream now a days that I even wonder why conferences like ‘The Agile Testingdays’ exists. The practice of agile test work should be crystal clear at this moment. So, mastering agile work is really the bear minimum.


Team Tools support.

Know your tools. Not only the common testing tool ‘Excel’ but more important the Application Lifecycle Management (ALM) tools the team uses.

ALM Tools like Visual Studio Online and other tools mentioned in the Gartner ALM report are important.

The tester isn’t alone anymore, testing isn’t the activity at the end of the waterfall what everybody skips, it is part of the delivery. Having knowledge how to use integrated team tools is a must to be valuable and not being a blocker of productivity.


Basic programing skills

Test automation is a must in the current fast delivery mindset of Continues Delivery. And this test automation must be, just like all the team work, integrated in the team process.

Standalone test automation tools are useless. Test automation connected with the team sprint tasks, the team build runs, the team delivery and the code base is a must for agile teams in being efficient with a focus on quality.

When test automation is in the same code base, in the same rhythm as the whole team, the code written for this test automation is logical the same programming language as the language the system is developed in, at least it is the most efficient.


Having basic programming skills as a tester is a must to be valuable for the team. As the image above shows, only just a small part is manual testing. So start to learn programming.



(Distributed) Version Control

Every artifact a team creates should be under version control. For the codebase it is normal to use a version control system. Either a centralized system like Visual Studio Online or a distributed system like GIT, everything is under version control.


All team members must understand the basics of version control. How to get or pull artifacts in or out and the pros and cons of the usages of branches.

Testers need to be capable to get the version they want to test from version control them self, they need to understand what artifacts are in the version and what features are delivered at what quality.

Knowledge of version control systems will make testers less depended on the other team members who do know what is in what version.

System under Test Deployment models.

As mentioned in the previous needed tester’s skill, testers should be less depended on other team members to get their system under test. Knowing how to deploy the software is a great added value for testers. This is for all kind of systems for example, knowing how to install a Store App on a tablet for testing will make the tester immediately more productive.

For more complex systems, knowing how PowerShell, Chocolaty, Puppet, Chef, Visual Studio Release Manager or other deployments mechanisms work would be great.

But at least understand how to start the deployment as a tester is the minimum. In the same category understand how to setup a test infrastructure for automated testing would be very useful.





Understanding the capabilities of current monitoring systems is a big benefit for testers. A tester who understands the behavior of the system under test is a invaluable benefit for the team. This tester helps to solve bugs as quick as possible by providing valuable usages statics, trace files or intellitrace files.



Cloud Systems

The last skill for a testers I want to talk about is Cloud. When a tester wants to stay in business, he or she needs to understand and usage the Cloud for testing.


Beside easy onboarding of new team members Dev & Test in the Cloud also can be used for your complete test infrastructure and with the new gained deployment knowledge also the provisioning of test environments should be easy for testers.

I can imagine you think ‘as a tester’ this isn’t my job role, these are the activities and skills of other. But as James Whittaker mentions in this post

“For the vast majority of app development on this planet, software testing is an activity within the development process …. It’s time to bring quality into the 21st century where testing is such an integral part of software development that you’ll often forget you are doing because it has become so familiar.


Testing is integrated in modern development, a testers must evolve. To stay valuable for teams and keep their job the in this post mentioned skills must be added to the capabilities of the modern tester.

Not only these capabilities count for testers, all other team members should master them too. So there is also some lessons to learn for developers.
