I'm having a problem not sure if it is a bug or not.
Making the long story short.
I use jmeter 3.0 and bundled json path extractor with some rest api to
make subsequent calls with foreach.
Lets say we have this scenario
country api -> region api ->city api->shop list
Get the country list and extract the array of country id and pass it to
a foreach get regions list for each country, another call to region api
and exctract the cities from the result
Generally everithing works, I get an array and the foreach works as
expected.
But there are situation where I get only one result, because for
instance there is only one region in the country.
In this case json path extractor do not give an array but a simple
string var. This cause the following foreach to not get executed.
I'm not sure if this is the normal behaviour but this completely broke
my script.
Another strange thinks is that I used the debug sampler to monitor the
script and the array never appear there but it exist since the foreach
get executed, the var appear only when is a string.
Here is a debug example:
idCountryList_1=37
idCountryList_2=38
idCountryList_ALL=37,38
idCountryList_matchNr=2
idR=8
idRegioneList_1=8
idRegioneList_2=12
idRegioneList_3=3
idRegioneList_ALL=8,12,3
idRegioneList_matchNr=3
idCityList=37006
idCityList_ALL=37006
idCityList_matchNr=1
for idCountryList I expect to see as first line something like
idCountryList = [37, 38]
While idCityList appear because is not an array since the json contain
just one result.
In this real example after extracting the city list I have another api
call that do not get executed because idCityList is not an array so the
foreach get jumped.
I hope I've been clear.
Thank for any support
