Microsoft visual studio test project

Type a name and create the project. Add the web service. Open WebService1. If you don't already have the web performance and load testing tools component installed, you'll need to install it through the Visual Studio Installer. In Visual Studio Installer , choose the Individual components tab, and scroll down to the Debugging and testing section. Select Web performance and load testing tools. In this section, we'll create a C load test project.

You can also create a Visual Basic load test project, if you prefer. Enter a name for the project if you don't want to use the default name, and then choose OK. On the Create a new project page, type web test into the search box, and then select the Web Performance and Load Test Project [Deprecated] template for C. Choose Next. Enter a name for the project if you don't want to use the default name, and then choose Create. Visual Studio creates the project and displays the files in Solution Explorer.

The project initially contains one web test file named WebTest1. In the web test project, open WebTest1. In the test editor, right-click the web performance test and select Add Web Service Request. For the web service, open a separate session of the browser and type the URL of the. At the top of the web page, select the method that you want to test and examine the SOAP message.

In the example web service, the method is HelloWorld. Return to the browser in step 4, select the XML portion of the SOAP request from the web service description page and copy it to the clipboard.

You expect the method to return true in these cases, so you can call the Assert. IsTrue method. Similarly, you want to provide a number of strings that begin with something other than an uppercase character. You expect the method to return false in these cases, so you can call the Assert. IsFalse method. Since your library method handles strings, you also want to make sure that it successfully handles an empty string String.

Empty , a valid string that has no characters and whose Length is 0, and a null string that hasn't been initialized. You can call StartsWithUpper directly as a static method and pass a single String argument.

Or you can call StartsWithUpper as an extension method on a string variable assigned to null. You'll define three methods, each of which calls an Assert method for each element in a string array. You'll call a method overload that lets you specify an error message to be displayed in case of test failure. The message identifies the string that caused the failure. In the UnitTest1. In the Confirm Save As dialog, select the Yes button to save the file.

The three tests are listed in the Passed Tests section, and the Summary section reports the result of the test run. If you're doing test-driven development TDD , you write tests first and they fail the first time you run them. Then you add code to the app that makes the test succeed. For this tutorial, you created the test after writing the app code that it validates, so you haven't seen the test fail. To validate that a test fails when you expect it to fail, add an invalid value to the test input.

You don't need to save the file because Visual Studio automatically saves open files when a solution is built to run tests. The Test Explorer window indicates that two tests succeeded and one failed. The Test Explorer window displays the message produced by the assert: "Assert. IsFalse failed. Expected for 'Error': false; actual: True". Because of the failure, no strings in the array after "Error" were tested. Now that the tests have all passed when running the Debug build of the library, run the tests an additional time against the Release build of the library.

A number of factors, including compiler optimizations, can sometimes produce different behavior between Debug and Release builds. In the Visual Studio toolbar, change the build configuration from Debug to Release.

In Solution Explorer , right-click the StringLibrary project and select Build from the context menu to recompile the library. The tests pass. NET console application using Visual Studio to debug code using your unit test project. Instead of starting the ShowCase app project, right-click the StringLibraryTests project, and select Debug Tests from the context menu.

Visual Studio starts the test project with the debugger attached. Execution will stop at any breakpoint you've added to the test project or the underlying library code. In this tutorial, you unit tested a class library.

You can make the library available to others by publishing it to NuGet as a package. To learn how, follow a NuGet tutorial:. Create and publish a NuGet package using Visual Studio.

If you publish a library as a NuGet package, others can install and use it. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode. Is this page helpful?
