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.
