Method Details

getDependency

<T> T getDependency(Class<T> dependencyClass)

Allows obtaining runtime dependency from within test body. Common types of dependencies would be State instance coming out of RequirementFulfillers and services for performing work on cluster (like QueryExecutor, HdfsClient, RemoteExecutor)

Type Parameters:

T - template

Parameters:

dependencyClass - Class of dependency to be obtained

Returns:

Dependency

getDependency

<T> T getDependency(Class<T> dependencyClass,
 String dependencyName)

getOptionalDependency

<T> Optional<T> getOptionalDependency(Class<T> dependencyClass)

Same as getDependency(Class) but will return Optional.empty() if no binding is present for given class.

Type Parameters:

T - template

Parameters:

dependencyClass - Class of dependency to be obtained

Returns:

Dependency

getOptionalDependency

<T> Optional<T> getOptionalDependency(Class<T> dependencyClass,
 String dependencyName)

Same as getDependency(Class, String) but will return Optional.empty() if no binding is present for given class.

Type Parameters:

T - template

Parameters:

dependencyClass - Class of dependency to be obtained

dependencyName - Name of dependency

Returns:

Dependency

createChildContext

TestContext createChildContext(Iterable<State> states)

Creates a new child TestContext with new Injector that contains new states.

Parameters:

states - requested states

Returns:

TestContext

createChildContext

default TestContext createChildContext(State... states)

registerCloseCallback

void registerCloseCallback(TestContextCloseCallback callback)

Registers a callback that will be executed on TestContext close.

Parameters:

callback - callback that will be executed on TestContext close.

injectMembers

void injectMembers(Object instance)

close

void close()

Closes this TestContext and all children TestContexts.
