Application Modernization
Faster, safer, more cost effective modernization
Generate high quality unit tests at scale, dramatically increase test coverage quickly and bring the risk of modernization right down.
Get the test coverage baseline you need to modernize applications safely.
Poor unit test coverage is a common trait of applications in need of modernization. Legacy code is often fragile, hard to understand and poorly documented – which makes unit test writing a difficult, time-consuming task. Diffblue’s autonomous AI can help you modernize business critical applications faster and with less risk.
Write unit tests faster than humanly possible.
Cover creates entire test suites 250 times faster than a human; allowing your team to pinpoint regressions earlier, fix bugs quicker, and reduce time spent navigating legacy code – saving years of manual developer effort.
Protect core functionality that already exists (business logic, interfaces, etc) across the months or years modernization will take, helping you to maintain operational continuity of systems that are already serving customers while you refactor your code.
Improve code coverage, fast.
Diffblue Cover is the only fully-automated AI solution that can autonomously write new code, improve existing code, accelerate CI pipelines and provide deep insights into the risk of change. This means huge increases in code coverage, no matter how large your legacy codebase is.
Cover helps your team get to grips with complex code from applications written by developers that left the business a long time ago, without having to throw your most experienced and expensive developer resources at the problem.
How Diffblue Cover helps enterprise modernize faster
1. Writes a complete, accurate test suite for your existing code
Diffblue Cover CLI describes the current behaviour of the code and writes an entire test suite that runs compiles, and is guaranteed to be correct for the code you’ve got.
2. Automatically ensures all pull/merge requests have maximum coverage
Diffblue Cover Pipeline analyzes a pull/merge request and fills any gaps and updates any tests required to maintain maximum test coverage.
3. Helps your developers quickly update unit tests when they make changes
Diffblue Cover IDE plugin assists developers in writing and updating their unit tests as they modernize the code.
