What is @contextconfiguration used for in context loader?
Consequently @ContextConfiguration can be used to declare either path-based resource locations (via the locations () or value () attribute) or annotated classes (via the classes () attribute). Note, however, that most implementations of SmartContextLoader only support a single resource type.
How to load classes annotated with @contextconfiguration in Java?
We can also load classes annotated with javax.inject . @ContextConfiguration annotation has following elements. classes: The classes annotated with @Configuration are assigned to load ApplicationContext . inheritInitializers: A Boolean value to decide whether context initializers from test super classes should be inherited or not. Default is true.
What is the difference between @configuration and @classes?
classes: The classes annotated with @Configuration are assigned to load ApplicationContext . inheritInitializers: A Boolean value to decide whether context initializers from test super classes should be inherited or not.
What does Spring boot test do?
The @SpringBootTest annotation is useful when we need to bootstrap the entire container. The annotation works by creating the ApplicationContext that will be utilized in our tests. We can use the webEnvironment attribute of @SpringBootTest to configure our runtime environment; we're using WebEnvironment.
What is AnnotationConfigContextLoader?
public class AnnotationConfigContextLoader extends AbstractGenericContextLoader. Concrete implementation of AbstractGenericContextLoader that loads bean definitions from component classes. See the Javadoc for @ContextConfiguration for a definition of component class.
What is Spring testing?
It ensures performance and quality of the product. The Java platform supports many testing frameworks. Spring introduces the principle of dependency injection on unit testing and has first-class support for integration testing.
What is the purpose of the @ContextConfiguration annotation in a JUnit test?
At its core, the TestContext framework allows you to annotate test classes with @ContextConfiguration to specify which configuration files to use to load the ApplicationContext for your test.
What are types of testing?
Here is a quick breakdown of the most common testing types:Accessibility testing.Acceptance testing.Black box testing.End to end testing.Functional testing.Interactive testing.Integration testing.Load testing.More items...
What is JUnit testing?
JUnit is a Java unit testing framework that's one of the best test methods for regression testing. An open-source framework, it is used to write and run repeatable automated tests. As with anything else, the JUnit testing framework has evolved over time.
How do you perform a springing test?
Technique. The patient lies in a prone position while the clinician applies force anteriorly with the thumbs over the spinous or transverse processes of the thoracic spine on both sides. The clinician looks for pain or hypomobility /hypermobility of the joint. The test is then considered positive.
Why do we use @ContextConfiguration?
@ContextConfiguration can load ApplicationContext using XML resource or the JavaConfig annotated with @Configuration . The @ContextConfiguration annotation can also load a component annotated with @Component , @Service , @Repository etc. We can also load classes annotated with javax.
What is ContextConfiguration annotation?
Annotation Type ContextConfiguration. @Target(value=TYPE) @Retention(value=RUNTIME) @Documented @Inherited public @interface ContextConfiguration. @ContextConfiguration defines class-level metadata that is used to determine how to load and configure an ApplicationContext for integration tests.
What is bean in Spring?
In Spring, the objects that form the backbone of your application and that are managed by the Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and otherwise managed by a Spring IoC container. Otherwise, a bean is simply one of many objects in your application.
Load JavaConfig
Find the example to define application context configuration class with @ContextConfiguration. Suppose we have AppConfig class annotated with @Configuration. We use @ContextConfiguration as following.
Load XML Configuration
Here we will load XML configuration class. Suppose we have spring-config.xml in classpath. We use @ContextConfiguration as following.
Load Initializer Class
We specify application context initializers classes using initializers element that initializes ConfigurableApplicationContext .
Using Custom Loader
Here we will use locations and loader element together. locations will specify XML configuration file and loader will specify custom context loader.

Examples
The following example shows how to use the ContextConfiguration class when you call the RegisterContext method in order to register a data context with scaffolding enabled.
Remarks
The ContextConfiguration class enables you to customize data access. For example, you can use this class to enable scaffolding for a Web application, or to define a custom metadata provider.
