When it comes to safety-critical systems—like aviation software or automotive control units—accuracy in testing is non-negotiable. That’s where MC/DC coverage (Modified Condition/Decision Coverage) comes into play. It ensures that every condition in a decision has been shown to independently affect the outcome, providing a rigorous level of testing beyond simple code or branch coverage.
By focusing on logical relationships within the code, MC/DC coverage helps identify hidden dependencies that might otherwise go unnoticed. This makes it a preferred standard in compliance frameworks like DO-178C and ISO 26262.
While implementing MC/DC coverage can be challenging, tools that automate condition tracking and test case generation make it more achievable. Investing in this metric isn’t just about meeting standards—it’s about building systems you can trust.
