Method Details

supportsParameter

public boolean supportsParameter(ParameterContext parameterContext,
 ExtensionContext extensionContext)

Description copied from interface: ParameterResolver

Determine if this resolver supports resolution of an argument for the Parameter in the supplied ParameterContext for the supplied ExtensionContext.

The Method or Constructor in which the parameter is declared can be retrieved via ParameterContext.getDeclaringExecutable().

Specified by:

supportsParameter in interface ParameterResolver

Parameters:

parameterContext - the context for the parameter for which an argument should be resolved; never null

extensionContext - the extension context for the Executable about to be invoked; never null

Returns:

true if this resolver can resolve an argument for the parameter

• ParameterContext

resolveParameter

public Object resolveParameter(ParameterContext parameterContext,
 ExtensionContext extensionContext)
                        throws ParameterResolutionException

Description copied from interface: ParameterResolver

Resolve an argument for the Parameter in the supplied ParameterContext for the supplied ExtensionContext.

This method is only called by the framework if ParameterResolver.supportsParameter(org.junit.jupiter.api.extension.ParameterContext, org.junit.jupiter.api.extension.ExtensionContext) previously returned true for the same ParameterContext and ExtensionContext.

The Method or Constructor in which the parameter is declared can be retrieved via ParameterContext.getDeclaringExecutable().

Specified by:

resolveParameter in interface ParameterResolver

Parameters:

parameterContext - the context for the parameter for which an argument should be resolved; never null

extensionContext - the extension context for the Executable about to be invoked; never null

Returns:

the resolved argument for the parameter; may only be null if the parameter type is not a primitive

Throws:

ParameterResolutionException

afterTestExecution

public void afterTestExecution(ExtensionContext context)

Description copied from interface: AfterTestExecutionCallback

Callback that is invoked immediately after an individual test has been executed but before any user-defined teardown methods have been executed for that test.

Specified by:

afterTestExecution in interface AfterTestExecutionCallback

Parameters:

context - the current extension context; never null
