Method Details

getDependency

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

Description copied from interface: TestContext

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)

Specified by:

getDependency in interface TestContext

Type Parameters:

T - template

Parameters:

dependencyClass - Class of dependency to be obtained

Returns:

Dependency

getDependency

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

Specified by:

getDependency in interface TestContext

getOptionalDependency

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

Description copied from interface: TestContext

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

Specified by:

getOptionalDependency in interface TestContext

Type Parameters:

T - template

Parameters:

dependencyClass - Class of dependency to be obtained

Returns:

Dependency

getOptionalDependency

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

Description copied from interface: TestContext

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

Specified by:

getOptionalDependency in interface TestContext

Type Parameters:

T - template

Parameters:

dependencyClass - Class of dependency to be obtained

dependencyName - Name of dependency

Returns:

Dependency

getOptionalDependency

public <T> Optional<T> getOptionalDependency(com.google.inject.Key key)

createChildContext

public GuiceTestContext createChildContext(Iterable<State> newStatesIterable)

Description copied from interface: TestContext

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

Specified by:

createChildContext in interface TestContext

Parameters:

newStatesIterable - requested states

Returns:

TestContext

createChildContext

public GuiceTestContext createChildContext(Iterable<State> newStatesIterable,
 Iterable<com.google.inject.Module> overrideModules)

registerCloseCallback

public void registerCloseCallback(TestContextCloseCallback callback)

Description copied from interface: TestContext

Registers a callback that will be executed on TestContext close.

Specified by:

registerCloseCallback in interface TestContext

Parameters:

callback - callback that will be executed on TestContext close.

close

public void close()

Description copied from interface: TestContext

Closes this TestContext and all children TestContexts.

Specified by:

close in interface TestContext
