Example: Creating a Test Class

The class MyPackage.TestMe contains a method named Add that adds two integers. In this example you create and run a unit test to check that the Add method correctly adds two integers.

Create a test class that will contain the unit tests. Here's how:

1. Use VS Code to create a new class named Tests in the MyPackage package. Tests must extend %UnitTest.TestCaseOpens in a new tab.

2. Add the following method named TestAdd and compile Tests:

   
   Method TestAdd()
   {
    do $$$AssertEquals(##class(MyPackage.TestMe).Add(2,2),4, "Test Add(2,2)=4")
    do $$$AssertNotEquals(##class(MyPackage.TestMe).Add(2,2),5,"Test Add(2,2)'=5")
   }
   

   

3. Copy the class file for Tests to a subdirectory within your unit test directory. For this example, copy the file to C:\unittests\mytests\cls\MyPackage.
