TestingThere are two popular Java testing frameworks: JUnit and TestNG. There was a time when TestNG was considered technically superior, but these days these two are pretty much the same. In this section we will describe how to use TestNG to test database access. 1. Add the following dependencies:
and set the scope of both dependencies to test. 2. Create the following folders:
then right click on the project and select Maven -> Update Project.... The testing code will be placed under src/test/java, which mirrors the structure of src/main/java, and the resource files used during testing will be placed under src/test/resources. 3. Copy src/main/webapp/WEB-INF/applicationContext.xml to src/test/resources. This bean configuration file will be used by the testing code to initialize the Spring framework and create beans for data sources, entity manager, and so on. 4. Create a test class as follows and place it under src/test/java/springmvc/model/dao:
In Eclipse, right click the class and select Run As -> TestNG Test. If you have created the database using springmvc-create.sql as described in the previous step, both tests should pass. |
