Traditional evaluation often summarizes performance with accuracy, loss or a task-specific score over a test set. These metrics can hide systematic failures on particular behaviors. Behavioral testing creates small, targeted examples and transformations to check whether model responses match explicit expectations. The CheckList framework for NLP organizes tests around capabilities and test types, including minimum functionality, invariance and directional expectation. The general idea applies more broadly when expectations can be specified responsibly. An invariance test changes an input in a way that should preserve the relevant meaning and checks that the output remains stable. Examples include punctuation changes in text or mild image brightness variation. A directional test applies a change that should predictably shift output in a particular direction, such as a validated increase in a risk factor under fixed conditions. A minimum-functionality test checks whether a basic capability works at all, such as handling negation or returning a valid structured response. These tests are valuable only when the expected behavior is justified. A transformation that seems harmless may alter meaning for some inputs, and a directional expectation may encode a contested assumption or fail due to interactions with other variables. Include counterexamples and define the scope of each test. Use domain experts to review expectations for high-impact applications. Tests should cover language variation, subgroups and edge cases without relying on stereotypes or fabricated labels. Behavioral tests complement, not replace, representative held-out evaluation, calibration, slice analysis and human review. A model can pass a small suite while failing in production; it can also fail an overly rigid test where multiple outputs are acceptable. Keep fixtures versioned, record why each expectation exists and investigate regressions rather than silently changing tests to pass. Evaluate generated outputs with appropriate tolerances and semantic checks. The result is a more specific view of model behavior than one aggregate score, not a guarantee of robustness or fairness.
