getInnermostInstance

public Object getInnermostInstance()

Description copied from interface: TestInstances

Get the innermost test instance.

The innermost instance is the one closest to the test method.

Specified by:

getInnermostInstance in interface TestInstances

Returns:

the innermost test instance; never null

getEnclosingInstances

public List<Object> getEnclosingInstances()

Description copied from interface: TestInstances

Get the enclosing test instances, excluding the innermost test instance, ordered from outermost to innermost.

Specified by:

getEnclosingInstances in interface TestInstances

Returns:

the enclosing test instances; never null or containing null, but potentially empty

getAllInstances

public List<Object> getAllInstances()

Description copied from interface: TestInstances

Get all test instances, ordered from outermost to innermost.

Specified by:

getAllInstances in interface TestInstances

Returns:

all test instances; never null, containing null, or empty

findInstance

public <T> Optional<T> findInstance(Class<T> requiredType)

Description copied from interface: TestInstances

Find the first test instance that is an instance of the supplied required type, checking from innermost to outermost.

Specified by:

findInstance in interface TestInstances

Parameters:

requiredType - the type to search for

Returns:

the first test instance of the required type; never null but potentially empty
