Class SpringBootContextLoader

java.lang.Object

org.springframework.test.context.support.AbstractContextLoader

org.springframework.boot.test.context.SpringBootContextLoader

All Implemented Interfaces:

ContextLoader, SmartContextLoader

public class SpringBootContextLoader
extends AbstractContextLoader

A ContextLoader that can be used to test Spring Boot applications (those that normally startup using SpringApplication). Although this loader can be used directly, most test will instead want to use it with @SpringBootTest.

The loader supports both standard MergedContextConfiguration as well as WebMergedContextConfiguration. If WebMergedContextConfiguration is used the context will either use a mock servlet environment, or start the full embedded web server.

If @ActiveProfiles are provided in the test class they will be used to create the application context.

1.4.0

Method Detail

loadContext

public ApplicationContext loadContext(MergedContextConfiguration config)
                               throws Exception

Throws:

Exception

getSpringApplication

protected SpringApplication getSpringApplication()

Builds new SpringApplication instance. You can override this method to add custom behavior

Returns:

SpringApplication instance

getEnvironment

protected ConfigurableEnvironment getEnvironment()

Builds a new ConfigurableEnvironment instance. You can override this method to return something other than StandardEnvironment if necessary.

Returns:

a ConfigurableEnvironment instance

getArgs

protected String[] getArgs(MergedContextConfiguration config)

Return the application arguments to use. If no arguments are available, return an empty array.

Parameters:

config - the source context configuration

Returns:

the application arguments to use

SpringApplication.run(String...)

getInlinedProperties

protected String[] getInlinedProperties(MergedContextConfiguration config)

getInitializers

protected List<ApplicationContextInitializer<?>> getInitializers(MergedContextConfiguration config,
                                                                 SpringApplication application)

Return the initializers that will be applied to the context. By default this method will adapt context customizers, add application initializers and add initializers specified on the test.

Parameters:

config - the source context configuration

application - the application instance

Returns:

the initializers to apply

Since:

2.0.0

processContextConfiguration

public void processContextConfiguration(ContextConfigurationAttributes configAttributes)

Specified by:

processContextConfiguration in interface SmartContextLoader

Overrides:

processContextConfiguration in class AbstractContextLoader

detectDefaultConfigurationClasses

protected Class<?>[] detectDefaultConfigurationClasses(Class<?> declaringClass)

Detect the default configuration classes for the supplied test class. By default simply delegates to AnnotationConfigContextLoaderUtils.detectDefaultConfigurationClasses(java.lang.Class<?>).

Parameters:

declaringClass - the test class that declared @ContextConfiguration

Returns:

an array of default configuration classes, potentially empty but never null

getResourceSuffixes

protected String[] getResourceSuffixes()

Overrides:

getResourceSuffixes in class AbstractContextLoader
