Create a unit test project
Unit tests often mirror the structure of the code under test. For example, a unit test project would be created for each code project in the product. The test project can be in the same solution as the production code, or it can be in a separate solution. You can have multiple unit test projects in a solution.
The location of unit tests for native code and the test project structure can be different than the structure that is described in this article. For more information, see Writing unit tests for C/C++.
To create a unit test project
- On the File menu, choose New > Project, or press Ctrl+Shift+N.
In the New Project dialog box, expand the Installed node, choose the language that you want to use for your test project, and then choose Test.
To use one of the Microsoft unit test frameworks, choose Unit Test Project from the list of project templates. Otherwise, choose the project template of the unit test framework that you want to use. Name the project, and then select OK.
On the Create a new project page, type unit test into the search box. Select the Unit Test Project (.NET Framework) project template, and then click Next.
On the Configure your new project page, enter a name for your project, and then click Create.
In your unit test project, add a reference to the code under test. To add a reference to a code project in the same solution:
Select the test project in Solution Explorer.
On the Project menu, choose Add Reference.
In Reference Manager, select the Solution node under Projects. Select the code project you want to test, and then select OK.
If the code that you want to test is in another location, see Managing references in a project for information about adding a reference.
