There’s a lot on the line when it comes to testing in aerospace and defense. Whether designing software to explore other galaxies, for military or commercial aircraft, for global information systems (GIS) mapping, or for command and control (C2) systems, companies and contractors are held to higher expectations and standards for accuracy, quality, reliability, and delivery. Which is why it’s not unheard of for testing to consume a big chunk of total product development cost across large, multiyear projects with contract delivery dates.
Teams frequently need to comply with government requirements and adhere to specific software development standards that define high-level processes for controlling software dev and testing. Not to mention the associated test documentation and traceability. Plus, developers need to manage quality throughout the entire project lifecycle, and avoid building up unquantifiable quality debt.
Testing in aerospace and defense must often be done as black-box testing, without access to the top-secret workings of the underlying software and systems. Not only does this mean that legacy, object-based testing isn’t viable, but even if it were, it would only be able to test for code correctness, not successful outcomes, which isn’t good enough. When you think about the potential ramifications of subpar software testing in aerospace and defense—including failure of vital systems and loss of life—it’s critical to get testing right.
