Code quality & Test Coverage
Achieve and maintain your test coverage and code quality gate
Generate high quality test cases across entire applications and maximise test coverage and application quality – with Diffblue Cover.
Imagine what your team could do if they didn’t have to worry about test coverage.
Never let a code quality gate slow shipping down again. Get the coverage you need to meet internal and regulatory demands with AI-powered unit test writing that can generate test suites across entire Java applications. And get your team back to building products that your end users love.
Increase test coverage to maximise risk coverage.
Accelerate the Software Development Lifecycle (SDLC) with high-quality tests that cover all the source code’s necessary branches and boundary values. Diffblue Cover automatically writes all the assertions needed for the tests so you know your code is doing what it’s supposed to.
Code coverage and quality gates might seem arbitrary and can often lead to the creation of simplistic tests that pass in order to meet targets, but don’t actually catch any bugs. Diffblue Cover creates tests that are consistent, readable, extensive in their pathway coverage and reflect the behavior of your code. The tests are readable so can be reviewed by a developer to ensure quality in the same way as you would review tests written manually.
Meet mandated test coverage targets and maintain that coverage over time.
Cover is designed to get good coverage “out of the box” without additional configuration. We work closely with our customers to optimize what the product can deliver and increase coverage over time, for example, by identifying ways to refine your build, tuning the product more specifically for your code using our custom rules engine, automatically refactoring certain kinds of untestable code to increase coverage, and working with you to identify other updates to code that will have the most impact on test coverage.
In cases where test coverage is insufficient, bugs can slip through the cracks, only to be discovered by QA teams or end users later down the line. Testing early and often can help you reduce the amount of QA you need to do by identifying defects as you go.
How Diffblue Cover elevates code quality and coverage
Elevate application development processes with proactive unit testing in order to proactively improve code quality and cost-saving defect reduction using Diffblue Cover.
1. AI-generated high quality tests
Generates comprehensive, human-readable unit tests tests that cover all source code’s necessary branches and boundary values. It also automatically writes all the assertions needed for the tests.
2. Scalable CI pipeline test automation
Ensure consistent and continuous code quality checks at every stage of the build cycle to mininmize regressions, errors and accelerate deployments.
3. Efficient AI-powered test operations
Leverages AI, to create reliable unit tests 250x quicker than a human, maintains test code entirely and intelligently prioritizes only the tests required to validate that code changes haven’t introduced regressions.
