Live Unit Testing

Background tests — you immediately see coverage and regressions. Key for CI/CD and TDD.

Code Coverage

Analysis of which part of the code is executed by tests. Detects modules omitted by testing.

Architecture Diagrams

Documentation of dependencies, system structure visualisation, consistency monitoring.

Load Testing Tools

Performance and load testing for corporate systems.
