unit testing - In MSTests is it possible to catch any exception? -


I'm trying to avoid a brittle test. I want to claim that a method throws an exception when invalid data is passed, and I do not care.

Take String.IsNullOrEmpty for example, if the string is empty, t want to throw a nullreference exception right? If it is empty, then I think you can leave the argument exception I do not think it is a good idea to have a separate guard section for blank versus spaces, and even if I just want to say that the exception is thrown from my unit has gone.

[Exceptions (Exception) (Exception)] Exception should pass an exception to give an error in saying. My solution is an attempt / catch block which has no fears. If an exception is not thrown, then file it. Is there a better / cleaner way?

It seems that trying means means that a common exception is thrown. Here is a thread on MSDN on this topic:

I still question the need to emphasize the general exception. If you are testing for a specific scenario, then you should know which exception should be thrown. For your example of using the string.IsNullOrEmpty () , it seems that you want to test both empty string and zero values. If the empty string is an invalid input then throwing a logic exposure seems appropriate and you can test against specific exceptions. If the string is a valid input, then you can test to make sure that it has not thrown an exception.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
