我想测试一个方法,它依赖于我的模型中的一个字段的值(用作参数)。我正在寻找如何嘲笑这个价值的帮助,所以我的单元测试将起作用。
未设置此值,测试将按照异常的路径进行。Moq - 指定参数值
控制器
public class StatusViewerController : Controller
{
private IERERepository _ereRepository;
//Dependency Injection
public StatusViewerController(IERERepository ereRepository)
{
_ereRepository = ereRepository;
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit([Bind(Include = "RecordID,ClientNumber")] StatusViewerFormViewModel model)
{
if (ModelState.IsValid)
{
try
{
//Send to one of two functions depending on RecordID value
if (model.RecordID == null)
{
_ereRepository.StatusViewerInsert(model);
}
else
{
_ereRepository.StatusViewerUpdate(model);
}
return new HttpStatusCodeResult(HttpStatusCode.OK);
}
catch
{
throw new HttpException(500, "Internal Server Error");
}
}
else
{
throw new HttpException(400, "ModelState Invalid");
}
}
}
单位测试
/// <summary>
/// Tests the Edit method for ActionResult return type
/// </summary>
[TestMethod]
public void StatusViewer_Edit_Returns_ActionResult()
{
//Arrange
var mockRepository = new Mock<IERERepository>();
StatusViewerController controller = new StatusViewerController(mockRepository.Object);
//Act
//I need to set the value of RecordID here or else this test will fail
//It will return an exception
ActionResult result = controller.Edit(It.IsAny<StatusViewerFormViewModel>());
//Assert
Assert.IsInstanceOfType(result, typeof(ActionResult));
