If you create a SQL Server unit test using SQL Server Object Explorer before you create a test project, a test project is created for you. Using Transact-SQL Assertions in SQL Server Unit TestsĬreate one or more test projects: You must create SQL Server unit tests in a test project. Using Test Conditions in SQL Server Unit Tests

You can also learn about how to use test conditions and Transact-SQL assertions in your unit tests.

Learn more about SQL Server unit tests: You can learn more about the files and scripts that compose a SQL Server unit test. Walkthrough: Creating and Running a SQL Server Unit Test Get hands-on practice: You can follow an introductory walkthrough to become familiar with how to create and run a simple SQL Server unit test. In the following table, you can find descriptions of common tasks that support this scenario and links to more information about how you can successfully complete those tasks. However, you cannot automatically generate a Transact-SQL stub that tests a function, trigger, or stored procedure without opening the project that contains the object that you want to test.

Remember, focus on quality code and the rest should magically fall into place.You can create an empty test, add code to it, and run it without having a SQL Server database project open. Bad code can be written using all three frameworks! If I had to pick, I would go with xUnit, if that's not possible for whatever reason, then I use NUnit. These are the things that are really important things to focus on and get correct compared to which test framework you choose. From my experience, it's these maintenance considerations that are key when writing tests on a project. Packages like Autofxiture will help alleviate those issues. Today, that gap has narrowed so the choice between all three is less.įrom my experience with unit testing, historically I've had worse problems dealing with the quality of the tests. 3 or 4 years ago the lack of certain features in MsTest made NUnit a better consideration. All three frameworks will probably do 99% of the things that you need to test on a day-to-day basis. I like xUnits notation and syntax and if you are installing a new test framework it is worth using. Obviously, as the newer kid, XUnit is also installed via NuGet with this command Install-Package xunit In xUnit you also don't have one test attribute, instead, you have and ! A Fact is a test that doesn't take any input parameters and a Theory is a test that does. In xUnit, you don't have a test set-up and tear-down like you would in MsTest and NUnit. xUnit has definitely changed the game in terms of its approach. So xUnit has been built from the learnings of NUnit. The makers of NUnit didn't like a few things about it so they went off and created xUnit. I think this feature is very handy and it can reduce the amount of boilerplate test code you need to write. The main reason I have always used NUnit was the ability to pass parameters into it tests: Personally, I prefer NUnits attribute naming conventions as I find it a little simpler and cleaner, however, in the grand scheme of life, it is a very tiny difference. Syntax is definitely a personal preference, so you will likely have a natural affinity to one or the other. In terms of the overall structure, things are similar, the main difference is syntax.

It integrates with the Resharper test suite well, so you can run your tests within Visual Studio and get real-time metrics about the state of your tests.Īn NUnit test class is constrcuted like this: NET, NUnit is installed via a NuGet package. NUnit has been around since 2006 and has been the most popular testing framework of choice ever since. A very basic test class using MSTest will look like this: NUNit Since V2 MSTest also supports parameters, so the difference between the frameworks has lessened a lot. For this reason, a lot of people opted to use NUnit instead. When it first came out, it didn't have a way to pass parameters into a unit test. MSTest has been around since Visual Studio 2015, at least. In today's tutorial, I'm going to quickly cover all three frameworks and hopefully give you enough information to pick which one works for you! MSTest NET and C# it can be hard to decide which test framework should you use? The main contenders are MsTest, NUnit and the newer kid on the block, xUnit. I won't go into the benefits of unit testing here, however, when you are new to unit testing in. NET project, you should be writing unit tests.
