Test projects in Visual Studio

This article describes the options for testing in Visual Studio.

A custom unit test adapter is available in Visual Studio. This adapter lets test authors use the standard Test Explorer window in Visual Studio to schedule X++ tests and analyze test results. Developers can author tests by using SysTestAdaptor. They can also generate test code from Task Recorder recordings. These test cases can then be added to build systems for validations.

Illustration of options for testing in Visual Studio.

Author unit/component test code by using the SysTest Framework

When you create a project in Visual Studio, you can add an X++ unit test. You extend the class with SysTestCase, and then either add the SysTestMethodAttribute attribute or prefix the case with "test" in the method name.

class FMUnitTestSample extends SysTestCase
{
    [SysTestMethod]
    public void testTotalsEngineConfig()
    {
    }
}

After you save the class, each test appears in Test Explorer, just as a C# test would appear.

Example of test appearing in Test Explorer.

In Test Explorer, you can run the tests, or you can debug the test case by right-clicking and running or debugging the selected tests.

Note

Before you can run tests, you must build the project so that it includes tests.

Example of right-clicking to run or debug selected tests.

You can also discover existing tests for an object in your project. Discovery uses cross-reference data. Right-click an object in the project, and then select Discover Related Tests. This command queries the cross-reference data and returns any tests that reference the object. The list of test cases is displayed in Test Explorer.

Example of test cases displayed in Test Explorer.

By using this functionality, you can run all the relevant tests. Test Explorer contains all tests for the current project and all tests for the referenced objects.

Generate test code by importing Task Recorder recordings into Visual Studio

You can import the XML for Task Recorder recordings to generate test code that can be used to validate various business process scenarios.

Example of Import Task Recording dialog box.

Generated code is based on the SysTest Framework and FormAdaptors. FormAdaptors are wrapper classes over pages. They provide strongly typed application programming interfaces (APIs) that can be used to test page functionality. Pre-generated FormAdaptors are included for each package for built-in pages. In a test module, add a reference to a corresponding FormAdaptor for packages and "Test Essentials," which contain helper methods to run test code.
