supportsParameter

public boolean supportsParameter(org.junit.jupiter.api.extension.ParameterContext parameterContext,
                                 org.junit.jupiter.api.extension.ExtensionContext extensionContext)

Determine if the value for the Parameter in the supplied ParameterContext should be autowired from the test's ApplicationContext.

Returns true if the parameter is declared in a Constructor that is annotated with @Autowired and otherwise delegates to ParameterAutowireUtils.isAutowirable(java.lang.reflect.Parameter, int).

WARNING: If the parameter is declared in a Constructor that is annotated with @Autowired, Spring will assume the responsibility for resolving all parameters in the constructor. Consequently, no other registered ParameterResolver will be able to resolve parameters.

Specified by:

supportsParameter in interface org.junit.jupiter.api.extension.ParameterResolver

See Also:

resolveParameter(org.junit.jupiter.api.extension.ParameterContext, org.junit.jupiter.api.extension.ExtensionContext), ParameterAutowireUtils.isAutowirable(java.lang.reflect.Parameter, int)

resolveParameter

@Nullable
public java.lang.Object resolveParameter(org.junit.jupiter.api.extension.ParameterContext parameterContext,
                                                   org.junit.jupiter.api.extension.ExtensionContext extensionContext)

Resolve a value for the Parameter in the supplied ParameterContext by retrieving the corresponding dependency from the test's ApplicationContext.

Delegates to ParameterAutowireUtils.resolveDependency(java.lang.reflect.Parameter, int, java.lang.Class<?>, org.springframework.context.ApplicationContext).

Specified by:

resolveParameter in interface org.junit.jupiter.api.extension.ParameterResolver

See Also:

supportsParameter(org.junit.jupiter.api.extension.ParameterContext, org.junit.jupiter.api.extension.ExtensionContext), ParameterAutowireUtils.resolveDependency(java.lang.reflect.Parameter, int, java.lang.Class<?>, org.springframework.context.ApplicationContext)

getApplicationContext

public static ApplicationContext getApplicationContext(org.junit.jupiter.api.extension.ExtensionContext context)

Get the ApplicationContext associated with the supplied ExtensionContext.

Parameters:

context - the current ExtensionContext (never null)

Returns:

the application context

Throws:

java.lang.IllegalStateException - if an error occurs while retrieving the application context
