Diffblue

Write tests for individual classes or methods

The Diffblue Testing Agent can write tests for individual classes or methods, allowing developers to focus on more complex tasks. This feature supports batch mode, which processes entire repositories without requiring file-by-file prompting, thus enhancing efficiency.

Agent generates and verifies tests

The Diffblue Testing Agent autonomously generates tests across your codebase, ensuring that every test compiles, passes, and adds real coverage. This built-in verification framework means that users never have to review broken tests, streamlining the testing process.

Unit test writing at scale

Diffblue Testing Agent can create an entire unit test suite for your whole application in a single execution. It understands how your code works and what tests need to be added and updated for every code change, significantly reducing the manual effort required.

Every test compiles, passes, and improves coverage

Each test generated by the Diffblue Testing Agent is verified to compile and pass before delivery, ensuring that users only pay for tests that actually work. This feature guarantees high-quality test coverage and reduces the risk of introducing errors into the codebase.

Smart regression test execution

This feature selects only the unit tests required to fully validate that a code change hasn’t introduced regressions. It outputs only dependable, human-readable unit test suites that compile, run, and validate code behavior, optimizing the testing process.

Works on your existing AI platform

The Diffblue Testing Agent extends existing AI platforms like GitHub Copilot CLI and Claude Code, allowing users to leverage their current tools while enhancing their testing capabilities. This integration ensures a seamless experience for developers.

Works with your enterprise-approved AI stack

Diffblue Agents are compatible with enterprise-approved AI coding platforms, ensuring that organizations can integrate the testing agent into their existing workflows without needing to evaluate new vendors. This compatibility enhances user adoption and satisfaction.

Continuous testing made effortless

Diffblue Testing Agent provides developers with fast feedback on the impact of code changes by executing only impacted test cases, either locally in IntelliJ or in CI pipelines. This significantly reduces waiting times and optimizes pull request workflows.

Maintains tests automatically

Once tests are written, the Diffblue Testing Agent maintains and updates them whenever a code change is made. This continuous operation ensures that the tests remain relevant and effective, reducing the manual effort required for test maintenance.
