Constructor Detail

ValueReplacer

public ValueReplacer()

ValueReplacer

public ValueReplacer(TestPlan tp)

Constructor which couples the given TestPlan to this by means of the user defined variables

Parameters:

tp - TestPlan from which we will take the user defined variables as variables map

Method Detail

setUserDefinedVariables

public void setUserDefinedVariables(Map<String,String> variables)

Set this ValueReplacer's variable map

Parameters:

variables - Map which stores the variables

replaceValues

public void replaceValues(TestElement el)
                   throws InvalidVariableException

Replaces TestElement StringProperties containing functions with their Function properties equivalent, example: ${__time()}_${__threadNum()}_${__machineName()} will become a FunctionProperty of a CompoundVariable containing 3 functions

Parameters:

el - TestElement in which the values should be replaced

Throws:

InvalidVariableException - when transforming of the variables goes awry and the used transformer throws an InvalidVariableException

reverseReplace

public void reverseReplace(TestElement el)
                    throws InvalidVariableException

Transforms strings into variable references

Parameters:

el - TestElement in which the we will look for strings, that can be replaced by variable references

Throws:

InvalidVariableException - when transforming of the strings goes awry and the used transformer throws an InvalidVariableException

reverseReplace

public void reverseReplace(TestElement el,
                           boolean regexMatch)
                    throws InvalidVariableException

Transforms strings into variable references using regexp matching if regexMatch is true

Parameters:

el - TestElement in which the we will look for strings, that can be replaced by variable references

regexMatch - when true variable substitution will be done in regexp matching mode

Throws:

InvalidVariableException - when transforming of the strings goes awry and the used transformer throws an InvalidVariableException

undoReverseReplace

public void undoReverseReplace(TestElement el)
                        throws InvalidVariableException

Replaces ${key} by value extracted from variables if any

Parameters:

el - TestElement in which values should be replaced

Throws:

InvalidVariableException - when transforming of the variables goes awry and the used transformer throws an InvalidVariableException

addVariable

public void addVariable(String name,
                        String value)

Add a variable to this replacer's variables map

Parameters:

name - Name of the variable

value - Value of the variable

addVariables

public void addVariables(Map<String,String> vars)

Add all the given variables to this replacer's variables map.

Parameters:

vars - A map of variable name-value pairs (String-to-String).
