Global AI in testing is projected to grow from $7.1 billion in 2023 to $34.0 billion by 2030, but many teams still rely on foundational unit testing frameworks, with 56% of developers reporting they use them in current projects. At the same time, standardized assessments are reaching far beyond labs, with 27 million learners using computer based testing under selected programs in 2023. This mix of rapid tech expansion and measurable impact across software and education makes the testing and assessment industry statistics surprisingly revealing.
