Make Dev Teams More Effective

Diffblue Cover helps developers deliver higher quality code, faster, accelerating your adoption of Shift Left and DevOps.

Unit test-writing is tedious and error-prone, and thousands of unit tests are required for even modest codebases. Without automated unit test-writing, your teams spend less time developing improvements for your products, slowing your time-to-market -- or don't write enough tests.

Diffblue Cover can write a unit test in about 2.5 seconds, making it an ideal partner for developers looking to get meaningful unit test coverage quickly. They can focus on writing the key unit tests that verify the intent of their code, while leadership can see the overall picture and address risks and gaps in coverage.

Prevent DevOps Bottlenecks

Software testing is the top bottleneck in DevOps, leading to regressions and ultimately slowing your development velocity and increasing time spent fixing bugs.

Diffblue’s products automate a key step in the DevOps pipeline that previously was 100% manual, helping you reduce risk and save time.

Modernize Legacy Code Quickly

Poorly unit-tested legacy code presents significant challenges. Writing sufficient unit tests by hand would take months or years, but lack of unit tests mean the code is hard to modernize.

Diffblue Cover solves this problem in hours, writing a full suite of regression unit tests. It then automatically maintains the test suite as your team modernizes and updates the code. Reports alert you to coverage gaps and help prioritize refactoring and quality engineering.

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.

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.
