Spring TestContext Framework
The Spring TestContext Framework (located in the org.springframework.test.context
package) provides generic, annotation-driven unit and integration testing support that is
agnostic of the testing framework in use. The TestContext framework also places a great
deal of importance on convention over configuration, with reasonable defaults that you
can override through annotation-based configuration.
In addition to generic testing infrastructure, the TestContext framework provides
explicit support for JUnit 4, JUnit Jupiter (AKA JUnit 5), and TestNG. For JUnit 4 and
TestNG, Spring provides abstract
support classes. Furthermore, Spring provides a custom
JUnit Runner
and custom JUnit Rules
for JUnit 4 and a custom Extension
for JUnit
Jupiter that let you write so-called POJO test classes. POJO test classes are not
required to extend a particular class hierarchy, such as the abstract
support classes.
The following section provides an overview of the internals of the TestContext framework. If you are interested only in using the framework and are not interested in extending it with your own custom listeners or custom loaders, feel free to go directly to the configuration (context management, dependency injection, transaction management ), support classes, and annotation support sections.
