How Your Dev Teams Benefit from Diffblue

On average writing and evaluating a single unit test can take a developer 10 minutes. And in order to achieve effectively high coverage there are 1000s of unit tests that need to be written. This means your team is spending less time developing improvement for your products, slowing your time-to-market or, worse, not writing enough unit tests that put your business at risk.

No more excuses: Update that legacy code!

If your teams have legacy code that’s stalling modernization or cloud migration, they can run Diffblue Cover’s test to better understand how this code behaves and make changes without worry.

Modernize Applications Without Fear

Application modernization is a high priority for many enterprises, but legacy code is often fragile, hard to understand, poorly documented and poorly tested. Writing the unit tests you need by hand would take months, or even years.

Diffblue Cover can improve quality, lower developer effort, help with code understanding and reduce risk.

By using Diffblue Cover to write a full unit test suite, you get the coverage baseline you need to start modernizing your applications safely. Cover then autonomously maintains the test suite as your team refactors and updates your code.

Reduce Lead Time For Changes

Software testing is the top bottleneck in DevOps, leading to regressions and slowing development velocity. Eliminating the burden of writing and maintaining unit tests allows Java teams to shift left and innovate with confidence. With up to 50% more developer time available, they can focus on building new features and getting better products to market faster.

With Diffblue’s AI for Code technology you can more easily meet coverage targets, agile planning is easier and more effective thanks to Cover's risk reporting dashboard, and unit testing becomes a scalable and reliable part of automated CI pipelines.

Increase Deployment Frequency

Most developers spend a significant chunk of their time on unit testing because they recognize its importance, but not many say they enjoy it.

Diffblue Cover’s AI-powered platform makes it easier for software developers to do their best work by eliminating the repetitive, tedious, unproductive effort of writing and maintaining unit tests. Developers can write quality code in less time, so you can ship more frequently.
