Method Detail

convert

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

Converts the given data to its corresponding arguments using the given parameterTypes and other provided information.

Parameters:

data - regex-separated String of parameters for test method

isVarArgs - determines whether test method has a varargs parameter

parameterTypes - target types of parameters to which corresponding values in regex-separated data should be converted

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

rowIdx - index of current data (row) for better error messages

Returns:

split, trimmed and converted Object[] of supplied regex-separated data

Throws:

java.lang.IllegalArgumentException - iif count of split data and parameter types does not match or argument cannot be converted to required type

splitBy

protected java.lang.String[] splitBy(java.lang.String data,
                                     java.lang.String regex)

checkArgumentsAndParameterCount

protected void checkArgumentsAndParameterCount(int argCount,
                                               int paramCount,
                                               boolean isVarArgs,
                                               int rowIdx)

customConvertValue

protected java.lang.Object customConvertValue(java.lang.String str,
                                              java.lang.Class<?> targetType,
                                              DataProvider dataProvider)

This method purely exists as potential extension point by overriding it.

Parameters:

str - value to be converted

targetType - target type into which value should be converted

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

Returns:

to target type converted String or OBJECT_NO_CONVERSION if no conversion was applied. Later will imply that normal conversions try to apply.

convertPrimaryOrWrapper

protected java.lang.Object convertPrimaryOrWrapper(java.lang.String str,
                                                   java.lang.Class<?> targetType)

convertToLong

protected java.lang.Object convertToLong(java.lang.String str)

convertToEnumValue

protected java.lang.Object convertToEnumValue(java.lang.String str,
                                              java.lang.Class<java.lang.Enum> enumType,
                                              boolean ignoreEnumCase)

tryConvertUsingSingleStringParamConstructor

protected java.lang.Object tryConvertUsingSingleStringParamConstructor(java.lang.String str,
                                                                       java.lang.Class<?> targetType)
