[英]Assert an Exception using XUnit
我是 XUnit 和 Moq 的新手。 我有一個將字符串作為參數的方法。如何使用 XUnit 處理異常。
[Fact]
public void ProfileRepository_GetSettingsForUserIDWithInvalidArguments_ThrowsArgumentException() {
//arrange
ProfileRepository profiles = new ProfileRepository();
//act
var result = profiles.GetSettingsForUserID("");
//assert
//The below statement is not working as expected.
Assert.Throws<ArgumentException>(() => profiles.GetSettingsForUserID(""));
}
測試方法
public IEnumerable<Setting> GetSettingsForUserID(string userid)
{
if (string.IsNullOrWhiteSpace(userid)) throw new ArgumentException("User Id Cannot be null");
var s = profiles.Where(e => e.UserID == userid).SelectMany(e => e.Settings);
return s;
}

}
被測方法
public IEnumerable<Setting> GetSettingsForUserID(string userid)
{
if (string.IsNullOrWhiteSpace(userid)) throw new ArgumentException("User Id Cannot be null");
var s = profiles.Where(e => e.UserID == userid).SelectMany(e => e.Settings);
return s;

我發現使用try catch塊最方便,而不是遵循復雜的協議:
try
{
var output = Settings.GetResultFromIActionResult<int>(controller.CreateAllFromExternalAPI());
Assert.True(output > 0);
}
catch(InvalidOperationException e)
{
Assert.True("Country table can only be filled from ExternalAPI if table is blank"==e.Message);
}
