Getting same Tests for different test scenarios

[mhettiarac]

Hi @kerrykimbrough

We noticed same test scenario was repeated with empty value for the petId, any reason why this happens?

In principle, these tests are checking 4 different error conditions. But there are 2 problems here. For 3 of these conditions (empty string, null, undefined), the representation of the path param happens to be the same. And for the 4th condition (not a string value), this can't really be represented at all, since every value is serialized as string.

TFOA needs to be smarter about avoiding such duplicate tests.
