Diffblue Cover is a fully autonomous AI-powered unit testing solution that writes and maintains entire Java unit test suites autonomously, with no developer intervention required. With the ability to write unit tests 250x faster than a human, Cover can rapidly build unit test suites at scale, freeing up developer time to focus on what they enjoy most, writing application code over test code, and higher-order problem-solving. Cover's AI is built on reinforcement learning, not large language models, producing higher quality and more accurate code for unit testing and enabling higher code coverage rates. Cover is available as a CLI tool, as a plugin for IntelliJ IDEA, and as a CI/CD integration.
