Method Detail

canConvert

public boolean canConvert(java.lang.reflect.Type type)

Returns true iif this DataConverter can convert the given type. Currently supported types:

• Object[][]
• Iterable<Iterable<?>>
• Iterable<?>
• Object[]
• String[]

Please note, that Iterable can be replaced by any valid subtype (checked via Class.isAssignableFrom(Class)). As well as an arbitrary inner type is also accepted. Only rawtypes are not supported currently.

Parameters:

type - to be checked for convertibility (use either Method.getGenericReturnType(), Method.getReturnType(), or simple Class if possible)

Returns:

true iif given type can be converted.

convert

public java.util.List<java.lang.Object[]> convert(java.lang.Object data,
                                                  boolean isVarArgs,
                                                  java.lang.Class<?>[] parameterTypes,
                                                  DataProvider dataProvider)

Converts the given Object to a List of Object[] with Classes correspond to given parameterTypes.

For compatible types, see canConvert(Type).

Parameters:

data - to be converted

isVarArgs - determines whether test method has a varargs parameter

parameterTypes - required types for data

dataProvider - containing settings which should be used to convert given data

Returns:

converted data as List<Object[]> with the required parameterTypes

Throws:

java.lang.NullPointerException - iif given parameterTypes or settings are null

java.lang.IllegalArgumentException - iif given parameterTypes is empty

java.lang.ClassCastException - iif data is not a compatible type
