我需要测试确切的Argument Exception是谨慎的。是否真的可以理解方法中的异常是警告吗?
public JsonResult Create(TeamViewModel teamViewModel)
{
JsonResult result = null;
try
{
// here exception throws
var domainTeam = teamViewModel.ToDomain();
...
}
catch (ArgumentException ex)
{
this.ModelState.AddModelError(string.Empty, ex.Message);
result = this.Json(this.ModelState);
}
return result;
}
我的单元测试此方法:
public void Create_InvalidTeamAchievements_ArgumentExceptionThrown()
{
Exception exception = null;
string invalidAchievements = CreateInvalidTeamAchievements();
// Arrange
var viewModel = new TeamMvcViewModelBuilder().WithAchievements(invalidAchievements).Build();
var sut = _kernel.Get<TeamsController>();
// Act
try
{
sut.Create(viewModel);
}
catch (ArgumentException ex)
{
exception = ex;
}
// Assert
VerifyExceptionThrown(exception, string.Format(Resources.ValidationTeamAchievements,
Constants.Team.MAX_ACHIEVEMENTS_LENGTH));
}

您正在以错误的方式对其进行测试。应该测试功能以不抛出异常,因为您已经在Create Method中捕获了异常。相反,如果在JsonResult
方法中引发异常,则应该断言包含ModelState
的{{1}}应该包含错误。
