The Benefits of Shift-Left Testing

December 5, 2018

This is part two of our shift-left testing series. A few weeks ago, we released part one, which explained the concept of shift-left testing and provided an overview of its methodology and history.

The shift-left testing methodology moves the testing part of web development closer to the beginning of the process instead of leaving it at the end. When you shift testing to the left it ensures that developers are testing earlier and more often.

This means bugs are found earlier in the development process and can be debugged quicker, which saves your team a lot of time and money. 

Here are the major benefits of shift-left testing. 

Save time

Let’s say you’ve just finished working on a feature request and have sent it off for testing. While you’re waiting for feedback, you begin working on another project. After a while, you’re told to go back and fix the bugs found in the original feature. 

Not only does this pull you away from your current work, but it costs you and your team unnecessary time spent re-working. 

When you shift testing to the left, you spend less time redoing work at the end of a project and can focus on the quality of work your team is producing from the beginning. Additionally, the less time you spend debugging, the faster you can deliver the product to your client

Shift-left testing helps your team adhere to timelines and ensures that deployments are smooth and bug-free. 

Save money

Developing is a domino effect. 

When your team spends additional hours redoing work, they have to be paid for them, and this can quickly deplete budgets. In fact, according to BitWise Global, bugs found at the end of the development process can cost more than fifteen times the original cost to fix. Yikes.  

Shift-left testing saves you from paying developers for countless hours of rework, which in turn, saves your client money.

Increase team collaboration 

If saving time and money weren’t already beneficial, shift-left testing also increases team collaboration. 

Shift-left testing brings project managers and developers together through testing. Both teams work together to establish quality standards.

Additionally, testing responsibility doesn’t fall solely on the QA team. Shift-left testing encourages developers to take accountability for their work. When all of your teams are collaborating together on a project, it increases communication between them.

It also creates more transparency on the client’s end, allowing them to view changes and updates as they’re happening, instead of waiting weeks or months for the end result. 

Shift-left testing is a win-win all around. 
Stay tuned for part three of this series which will provide you with a guide on how to get started with shift-left testing.
