regex - Using JMeter's Regular Expression Extractor, where does the output get saved? -

i using regular expression extractor extract authentication code need use in following jmeter sampler in test. code saved in response header authentication: djdjf...## (a bunch of letters , numbers followed ##).

in regular expression extractor "field check" selected "response headers" radio button.

then entered:

reference name: auth

regular expression: \a\w*==\z

template: $1$

match no. (0 random): 1

default value: not found

where results regular expression extractor execution saved?

i hoping results saved in user defined variable, defined auth in test plan's user defined variable section, if enter auth in "reference name" of regular expression extractor, , run jmeter, auth never gets populated.

very easy , simple way is:-

after regular expression extractor put debug post processor.

1- right click on request created regular exp -> add -> post processor -> debug postprocessor

2- in debug postprocessor @ place of name give variable name taken extract, ${name}

3- in listener part after test run exact value passed in regular expression.
