When identifying test patterns in code, use specific equality predicates (`#eq?`) instead of list inclusion predicates (`#any-of?`) when matching against a single value. This improves clarity and can avoid potential false positives in test detection. For example, when matching the "each" method for parameterized tests: ```javascript // Prefer this: (#eq? @_property "each") // Instead of this when there's only one value: (#any-of? @_property "each") ``` This practice ensures more precise test pattern recognition, especially important for parameterized tests where accurate detection affects test execution and reporting.
