Additional Functions

In addition to standard JMeter functions we provide:

doubleSum^{since 0.4.2}

This function used to compute the sum of two or more floating point values.

Parameters:

1. First value to sum - required
2. Second value to sim - required
3. More values to sum - optional
4. Last argument - variable name to store the result

Example, returning 8.3 and also saving it to variable sumVariable:

${__doubleSum(3.5, 4.7, sumVariable)}

strLen^{since 0.4.2}

This function used to compute the length of constant string or variable value.

Parameters:

1. First value is string constant, variable, or function call - required
2. Second argument - variable name to store the result

Example, returning 11 and also saving it to variable lenVariable:

${__strLen(test string, lenVariable)}

Example, returning length of variable varName:

${__strLen(${varName})}

uppercase and lowercase^{since 0.4.2}

This functions used to transform the case of constant string or variable value.

Parameters:

1. First value is string constant, variable, or function call - required
2. Second argument - variable name to store the result

Example, transforming 'test' into 'TEST' and also saving it to variable someVariable:

${__uppercase(test, someVariable)}

MD5^{since 0.4.2}

This function used to calculate MD5 hash of constant string or variable value.

Parameters:

1. First value is string constant, variable, or function call - required
2. Second argument - variable name to store the result

Example, calculating MD5 for 'test':

${__MD5(test)}

isDefined^{since 0.4.2}

This function used to determine if variable was already defined. Returns 1 if variable was defined, 0 instead.

Parameters:

1. First value is string constant, variable, or function call - required

Example, getting defined status for variable name 'testVar':

${__isDefined(testVar)}

substring^{since 0.4.2}

This function is wrapper for Java String.substring method.

Parameters:

1. First value is string constant, variable, or function call - required
2. Begin index
3. End index
4. Optional variable to store result

Example, getting 'str' from 'test string':

${__substring(test string, 5, 8)}
