Understanding the Limitations of Software Testing: The Mathematics of Verification

In this snippet from Elektor Engineering Insights #54, we explore why traditional software testing can never guarantee 100% reliability and how formal verification provides mathematical certainty that testing simply cannot achieve. Quentin Ochem from AdaCore explains the fundamental limitation of testing - even a simple function with two integers would require an astronomically large number of test cases to verify exhaustively - and how formal verification tools such as Spark use mathematical proofs to demonstrate software correctness across ALL possible execution paths with 100% certainty, which is especially critical for security applications where attackers only need to find one exploit in millions of lines of code.
