Use MockMvcResultMatchers' jsonPath() for JSON validation.
With MockMvc, you can validate JSON structures in your response using jsonPath(). This is particularly useful for checking if your API returns the expected data. For example, in a product catalog API, you can assert that the JSON response contains a product with a specific name by using jsonPath("$.name").value("Product Name").
