สมมติว่าเรามี Data Structure ดังนี้ คำถามคือเราจะ Assert อย่างไร

public class Todo
{
public int ID { get; set; }
public string Title { get; set; }
public bool Completed { get; set; }
}
public class TodoList
{
public IEnumerable<Todo> GetTodoList()
{
return new []
{
new Todo{
ID = 0,
Title = "Shopping",
Completed = false
},
new Todo{
ID = 1,
Title = "Running",
Completed = true
},
new Todo{
ID = 2,
Title = "Reading a book",
Completed = false
}
};
}
}

ถ้าใช้ xUnit อย่างเดียว อาจจะยุ่งยาก ลองใช้ FluentAssertions

Getting Started

  1. ติดตั้ง FluentAssertions

    dotnet add package FluentAssertions --version 5.10.3
  2. เรียก using FluentAssertions; แล้วเราสามารถใช้งาน FluentAssertions ได้เลย

    using Xunit;
    using FluentAssertions;
    public class TodoListTest
    {
    [Fact]
    public void GetTodoListTest()
    {
    var todoList = new TodoList();
    var expected = new []
    {
    new Todo{
    ID = 0,
    Title = "Shopping",
    Completed = false
    },
    new Todo{
    ID = 1,
    Title = "Running",
    Completed = true
    },
    new Todo{
    ID = 2,
    Title = "Reading a book",
    Completed = false
    }
    };
    var result = todoList.GetTodoList();
    result.Should().BeEquivalentTo(expected);
    }
    }
