我有一个通用的测试方法,我想测试所有不合格,如果出现:
private async Task TestNotification(INotification notification)
{
var result await _notificationService.SendNotification(notification);
Assert.Something(result);
}
是否可以批注TestNotification
方法,以便Visual Studio将发现每个通知实例的测试?我目前只有一个测试:
[TestMethod]
public async Task TestAllNotification()
{
var notificationTypes = typeof(INotification).Assembly.GetTypes()
.Where(t => typeof(INotification).IsAssignableFrom(t) && !t.IsAbstract)
.ToArray();
foreach (var type in notificationTypes)
{
try
{
var instance = (INotification)Activator.CreateInstance(type);
await TestNotification(instance);
}
catch(Exception ex)
{
throw new AssertFailedException(type.FullName, ex);
}
}
}
好消息!您应该发现 MsTestV2 中的 new-ish [DynamicData]
属性可以解决您的情况:
[DynamicData(nameof(AllNotificationTypes))]
[DataTestMethod]
public async Task TestNotification(Type type)
{
}
public static Type[] AllNotificationTypes
=> typeof(INotification).Assembly.GetTypes()
.Where(t => typeof(INotification).IsAssignableFrom(t) && !t.IsAbstract)
.ToArray();
