public interface ContextLoader
Strategy interface for loading an ApplicationContext for an integration test managed by the Spring TestContext Framework.

NOTE: as of Spring Framework 6.0, ContextLoader is effectively a marker interface and should not be implemented directly. Implement SmartContextLoader instead of this interface in order to provide support for annotated classes, active bean definition profiles, application context initializers, and various other features not supported by methods defined in the ContextLoader SPI.

Clients of a ContextLoader should call processLocations() prior to calling loadContext() in case the ContextLoader provides custom support for modifying or generating locations. The results of processLocations() should then be supplied to loadContext().

Concrete implementations must provide a public no-args constructor.

      Processes application context resource locations for a specified class.

      Concrete implementations may choose to modify the supplied locations, generate new locations, or simply return the supplied locations unchanged.

      clazz - the class with which the locations are associated: used to determine how to process the supplied locations
      locations - the unmodified locations to use for loading the application context (can be null or empty)

      @Deprecated(since="6.0") ApplicationContext loadContext(String... locations) throws Exception
      as of Spring Framework 6.0, in favor of methods defined in the SmartContextLoader SPI
      Loads a new ApplicationContext based on the supplied locations, configures the context, and finally returns the context in fully refreshed state.

      Configuration locations are generally considered to be classpath resources by default.

      Concrete implementations should register annotation configuration processors with bean factories of application contexts loaded by this ContextLoader. Beans will therefore automatically be candidates for annotation-based dependency injection using @Autowired, @Resource, and @Inject.

      Any ApplicationContext loaded by a ContextLoader must register a JVM shutdown hook for itself. Unless the context gets closed early, all context instances will be automatically closed on JVM shutdown. This allows for freeing external resources held by beans within the context, e.g. temporary files.
