如何在 Xunit 中使用 Assert.Throws 引发异常

Question

i am trying to write a test case using Xunit where i want check if the text i am passing is not expected one throw exception saying the value should be the same only

Here is my code

   [Theory]
   [InlineData("Goods","Goods")]
   [InlineData("Test","Goods")]
   public void Vehicle(string use,string expected)
   {
      // Arrange
      var risk= CreateRisk();
      var request = new Request();

      risk.Use = use;
      
      // Act
      Test().Mapping(risk, request);
      
      // Assert
     Assert.Throws<ArgumentException>(expected != "Goods" ? "Vehicle Use Should be with Goods": expected);
  
   }

I am not sure how i can frame this. Thanks in advance

You need to capture the exception result during your act:

  // Act
  var result = Assert.Throws<ArgumentException(() => Test().Mapping(risk, request));
  
  // Assert
 result.Message.Should().Be(expected);
