nanovision for Windows

Product snapshot

Nanovision is a free Windows utility that produces easy-to-read code coverage reports. Built with Go projects in mind, it links with gocover to show which portions of your codebase were exercised by tests. The visualization of executed and unexecuted code makes it a practical aid for test automation and ongoing quality control.

• Seamlessly hooks into the gocover tooling used by Go developers
• No-cost availability for Windows environments
• Visual indicators that reveal which source lines ran during testing

Practical advantages for developers
