How do you skip or ignore tests in xUnit?

Short answer: Use the Skip property on [Fact] or [Theory]: [Fact(Skip = "Reason for skipping")] public void SkippedTest() { }

Real-world example (ShopNest)

ShopNest unit tests cover pricing and discount rules so a bad coupon change fails in CI before customers see it.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
