Field Summary

Fields

Modifier and Type	Field	Description
static java.lang.String	DEFAULT_PARAMETER_NAME	The "fake" name of the default parameter.
static java.lang.String	EMPTY_VALUE	A fixed result "value" object indicating that a result value was an empty collection.
static java.lang.String	INEXISTENT_VALUE	A fixed result "value" object indicating that a result value actually did not even exist in the named results returned by a fixture (not even with a "null" value, which is a different kind of statement).

getValuesFromNamedResultContainer

public static java.util.Map<java.lang.String,java.lang.Object> getValuesFromNamedResultContainer(java.lang.Object aContainer)
                                                                                                throws java.beans.IntrospectionException,
                                                                                                       java.lang.IllegalArgumentException,
                                                                                                       java.lang.IllegalAccessException,
                                                                                                       java.lang.reflect.InvocationTargetException

Returns a map of named result names to values acquired from a given named result container. This container is assumed to be a simple Java Bean, with accessible accessor methods useable to retrieve the values of fields. The field names are used as result names and thus keys in the map. Unreachable fields are ignored.

Parameters:

aContainer - the container instance

Returns:

the map of result names to values

Throws:

java.beans.IntrospectionException - the introspection exception

java.lang.IllegalArgumentException - the illegal argument exception

java.lang.IllegalAccessException - the illegal access exception

java.lang.reflect.InvocationTargetException - the invocation target exception

getResultTypeFromNamedResultContainerType

public static java.lang.Class<?> getResultTypeFromNamedResultContainerType(java.lang.Class<?> aContainerType,
                                                                           java.lang.String aResultName)
                                                                    throws java.beans.IntrospectionException

Determines the result type by looking at a result container type for a specific result name.

Parameters:

aContainerType - the container type

aResultName - the name of the result

Returns:

the result type

Throws:

java.beans.IntrospectionException - the introspection exception

getVariableEntitiesForSuiteParameters

public static java.util.List<VariableEntity> getVariableEntitiesForSuiteParameters(SuiteDefinition aSuite)

Determines a list of all VariableEntitys referenced in a suites' parameter list.

Parameters:

aSuite -

Returns:
