vitest/no-conditional-tests Correctness
What it does
The rule disallows the use of conditional statements within test cases to ensure that tests are deterministic and clearly readable.
Why is this bad?
Conditional statements in test cases can make tests unpredictable and harder to understand. Tests should be consistent and straightforward to ensure reliable results and maintainability.
