Integration: Diffblue Cover supports integration with popular build tools such as Maven and Gradle. Additionally, it offers a plugin for IntelliJ IDEA, facilitating interactive test writing.
CI/CD Integration: The tool can be seamlessly incorporated into Continuous Integration/Continuous Deployment (CI/CD) pipelines, automating the unit testing process and ensuring that tests are generated and maintained at scale.
Code Coverage: Diffblue Cover helps developers achieve and maintain code coverage targets by generating and executing tests that cover complex code segments.
Legacy Code Support: This feature is particularly beneficial for legacy Java codebases that may lack sufficient unit tests, as it helps document all known behaviors of the existing code.

Benefits of Using Diffblue Cover

Implementing Diffblue Cover in development workflows offers several advantages:

Increased Productivity: Developers can save up to 95% of the time typically spent on manual unit test writing and maintenance. This allows them to concentrate more on writing application code, thereby enhancing overall productivity.
Improved Code Quality: By reducing the impact of code quality gates on the Service Level Development Commitment (SLDC), Diffblue Cover enables faster releases to market without compromising on quality.
Enterprise-Grade Solution: The tool is designed to handle large and complex codebases, having already covered over 59 million lines of code and saving developers an impressive 976 years of time.

Pricing and Availability

Diffblue Cover is available as a Command Line Interface (CLI) tool compatible with Windows, Linux, and macOS. The pricing model is based on the number of lines of code, with a 12-month contract available for up to 200,000 lines at a cost of $30,000.

How Diffblue Cover Solves Problems

Diffblue Cover addresses several challenges faced by developers in the software testing landscape:

It automates the generation of unit tests, significantly reducing the manual effort required and minimizing human error.
The tool enhances test coverage, which is crucial for identifying regressions and ensuring that code changes do not introduce new bugs.
By supporting legacy code, Diffblue Cover helps teams modernize their codebases, making it easier to maintain and extend existing applications.
