NetBeans can create the basic test class for us:

1. Right click your Calculator class in the <

   > pane and select < Create/Update Tests">>.

2. The default class name should be OK. Set the rest of the options as follows:

   {{/Labs/02/Diagrams/Create Tests Dialog}}

   These are fairly typical settings for creating test classes.

3. Click <

   >. The test class will be created, and opened.
