Question

这是我的课程要测试：

namespace UnitTestProject1
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        [ExpectedException(typeof(TaskCanceledException))]
        public async Task TestMethod1()
        {
            var mock = new Mock<MyClass>
            {
                CallBase = true
            };
            mock.Protected().Setup<Task>("DoSomethingInternal", new MyContext()).ThrowsAsync(new TaskCanceledException());
            var obj = mock.Object;

            await obj.DoSomething(null);
        }

        [TestMethod]
        [ExpectedException(typeof(TaskCanceledException))]
        public async Task TestMethod2()
        {
            var mock = new Mock<MyClass>
            {
                CallBase = true
            };
            mock.Protected().Setup<Task>("DoSomethingInternal").ThrowsAsync(new TaskCanceledException());
            var obj = mock.Object;

            await obj.DoSomething();
        }
    }
}

这是测试代码：

DoSomethingInternal(context)

结果显示，第一个测试失败，第二个成功。调试显示，第一次测试对Task.CompletedTask的调用返回get，而不是引发异常。

那我怎么扔呢？

在设置中传递的参数与执行测试时传递的实例不匹配。在这种情况下，您需要使用参数匹配器，以使代码按预期方式流动。

为受保护成员设置期望，如果需要参数匹配，则必须使用PHP CODE: <?php $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "dbname"; // Create connection $conn = new mysqli($servername, $username, $password, $dbname); // Check connection if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } $menu= htmlspecialchars($_GET["menu"]); $sql = "select name,menu,price,picture,description from items where menu='$menu' order by menu asc"; $result = $conn->query($sql); $arr=array(); if ($result->num_rows > 0) { // output data of each row while($row = $result->fetch_assoc()) { array_push($arr, $row); } echo json_encode($arr); } else { echo "0 results"; } $conn->close(); ?> Output: [{"name":"XXXXX","menu":"YYYYY","price":"311.55","picture":"https:\/\/www.google.com\/test\/item\/test.jpg","description":"Test Message"}] Expected Output: { "data":[ { "name":"XXXXX", "menu":"YYYYY", "price":"311.55", "picture":"https:\/\/www.google.com\/test\/item\/test.jpg", "description":"Test Message" } ] }而不是ItExpr
