For example we want to run the same test 5 times and want to set some property value before running each time. In this scenario we can define one function and decorate the function with a TestInitialize attribute.

This attribute is like the opposite of TestInitialize, each time the function is decorated with this attribute it will execute when test execution finishes. So, after execution of each and every test if we need to perform some cleanup operation then we can write code within this function. Ok, so let me discuss one real scenario using both of them. For example we need to perform a unit test to a function where the function will get data from a file and we need to test the function 5 times with various input values and depending on the input value the file will be created.

Oh, it is a little complex situation. So, we can divide the entire operation in this way, at first we will create a file using a function that is decorated by a TestInitialize attribute and after performance of a test we will delete the file in the function that is decorated with a TestCleanup attribute. Here is our class that we want to test using a unit test application. If you are very new to a unit test, I will suggest you to go through our previous articles.

Anyway, I take it it is not possible to do the same thing with a. The AssemblyInitialize method is not exactly the same since we have multiple test assemblies, but only want to run the setup script once for the entire test run. But if there is no other way, I guess we'll have to figure out something using this methodology in that case. I did some search, it seems that this is an existing issue from vs Update 2 when we debug unit test with shims.

VSTest does not perform Shims instrumentation in legacy mode which may be enabled implicitly, by selecting a. You can try to turn off the global profiling environment to check whether it can help. Microsoft said that the issue will be fixed in the next version of VS. I suggest using VS to see whether the issue has been resolved. Meanwhile I also will check it. Sorry to hear that. I am afraid that the issue is still not fixed in VS After you submit the feedback, you can post the link here which will be beneficial for other members with the similar issue.

And I will help you to vote it. The content you requested has been removed. Ask a question.
