Nice tool, generates good, readable unit tests for modern Spring applications. Could be faster, but still much more efficient than getting my head around the vagaries of JUnit, mocking etc

Fantastic tool. Really accelerates test development. The community support is great also.

The plugin helps you to create units tests using AI algorithms. It is not only saving your time but also covering test cases that you might never think about and showing you how to refactor your code to make it testable. There is a new release every 2 weeks. I am a happy user so far.

Only just got the chance to try this out- it generated really good unit tests and will save me a bunch of time.

Frequently Asked Questions

Who needs a license for Diffblue Cover?

Any developer who uses Diffblue generated tests needs a license key to validate and activate the product. This includes anyone either:

  • Directly generating and/or running tests through their desktop
  • Indirectly generating and/or running tests through an automated build pipeline. 

Diffblue pricing is based on lines of code in the projects where it is used, not on individual user licenses.

For more information view our license documentation. 

What is Diffblue Cover?

Diffblue Cover creates suites of unit tests that run in your continuous integration pipeline between versions and protect against regressions, so you can catch errors faster and earlier in the software development lifecycle. To learn more, see our our product page.

What are the benefits of using Diffblue Cover?

Diffblue Cover helps your team increase automation of your CI pipeline.

For development teams, this:

  • improves velocity and quality of the software you deliver
  • frees up time to focus on creating new features

For DevOps teams, this:

  • helps catch errors and issues earlier (shift left!)
  • improves deployment frequency, lead time, and mean time to repair (MTTR)

Will the tests find regressions in my code?

Yes. Diffblue Cover quickly generates tests that will allow you to adopt CI. The generated tests will help developers quickly identify regressions in subsequent commits before committing new versions.

What are the requirements for running Diffblue Cover?

See the product datasheet for more information.

How can I learn more about customers using Diffblue Cover?

See our case study on how Goldman Sachs has benefited from using Diffblue Cover to increase coverage and create a safety net against regressions.

For example of other ways our customers use Diffblue Cover, click here.

How do we maintain Diffblue unit tests in the future?

Diffblue regression suites are maintained automatically and updated with each new code version to capture the current behavior of the code.

How does Diffblue Cover help me adopt Continuous Integration?

Diffblue Cover AI analyzes your code and writes Java unit tests that run in a CI pipeline after each commit. Cover’s tests:

  • Always compile
  • Run quickly
  • Detect regressions from previous versions
  • Improve coverage
  • Are easy to understand

Should our team stop writing unit tests after adopting Diffblue Cover?

No. Diffblue Cover is meant to complement your own unit tests and help you catch regressions.

How is a unit test different from a Diffblue regression suite?

Developers write individual unit tests to test specific functionality. Diffblue regression suites are generated automatically to help find regressions early in the development cycle. Find out more in our Unit Regression Tests eBook.
