How to Test Minimal APIs?

Short answer: How to Test Minimal APIs? Answer: Minimal APIs are tested using WebApplicationFactory or TestServer. Example: var factory = new WebApplicationFactory<Program>();

Example code

var client = factory.CreateClient();
var response = await client.GetAsync("/products");
var products = await response.Content.ReadFromJsonAsync<List<Product>>(); Assert.NotEmpty(products);

Real-world example (ShopNest)

ShopNest admin screens use MVC: controller loads data, Razor view renders HTML, Tag Helpers build forms safely.

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.
