I am traying the extract the term-id- id value -200000000326 from the below response. controlled-term can have multiple term-id, I have tried with Json extractor $..controlled-term.[[term-id]].[id] and [Thursday 12:22 PM] G, Shwetha C
$..term-id[id]
but this is returning null. can you please help
enter code here:
{
"controlled-terms": {
"controlled-term": [
{
"term-id": {
"id": "200000000326"
},
"term-names": {
"term-name": [
{
"lang": "en",
"name": "All"
}
]
}
}
]
}}
For particular that JSON you provided the relevant JSONPath query would be something like:
$.controlled-term.*.term-id.id
If you need to extract particular ID which is related to some other attribute value - you will have to provide the full JSON response and specify the data relationships.
I would also recommend considering switching to JSON JMESPath Extractor mainly because it has official specification (JSONPath implementations are lacking it so query which works for one implementation may fail for another). Moreover JMESPath language is more powerful and provides a lot of functions and operators which can make your life easier. More information: The JMeter JSON JMESPath Extractor and Assertion: A Guide

My current test suite requires me to send some HTTP POST requests to API, some of which require specific objects to be posted via HTTP Request. I encountered some problems when trying to fetch those object from my YAML file when running Jmeter in Taurus.
I will attach part of my YAML file here for context (had to delete of change some properties for confidentiality):
jmeter:
properties:
number.of.users: 1000
rampup.period: 300
loop.count: 1
client.id: "23id"
array.of.clients: ["id1","id2","id3"]
ids: [1,2,3]
rq:
- "number": "7312sa1"
"signed": "2020-06-08T00:00:00.000+0000"
"crmClientId": "1-32D1P"
The problem is: when I try to pass string properties to my HTTP Request like that:
{
"id": 1986,
"jsonrpc": "2.0",
"method": "method",
"params":
{
${__P(rq,)}
}
}
all properties are wrapped in single quotation marks which causes request to receive error 400 in return because request after acquiring property is looking like this:
{
"id": 1986,
"jsonrpc": "2.0",
"method": "method",
"params":
{
'rq':
'number': '7312sa1'
'signed': '2020-06-08T00:00:00.000+0000'
'crmClientId': '1-32D1P'
}
}
Is there a way to pass string properties to request with double quotation marks or structure my YAML file in a way, which will construct request according to this example:
{
"id": 1986,
"jsonrpc": "2.0",
"method": "method",
"params":
{
rq:
"number": "7312sa1"
"signed": "2020-06-08T00:00:00.000+0000"
"crmClientId": "1-32D1P"
}
}
I tried using groovy replaceAll() method but it doesn't work with complex objects. My only solution as of right now is running some sort of groovy script in setUp thread and then acquire them is HTTP request via groovy jmeter function
You're sending a string representation of Python's dictionary, you need to send it as a simple string.
Check out YAML Multiline Strings and choose the most convenient option for you.
Example usage:
modules:
jmeter:
properties:
rq: >
\n"number": "7312sa1"\n
"signed": "2020-06-08T00:00:00.000+0000"\n
"crmClientId": "1-32D1P"\n
Taurus is presumably built to make testers and/or devops lives easier, it doesn't seem that it's your case, perhaps you should consider switching to JMeter without any wrappers instead?
My http request returns a json similar to this:
{
"ReturnData": {
"Foo_ef49f92628083fab6e14545c547bcf38": {
"ViewId": "Foo_ef49f92628083fab6e14545c547bcf38",
"ViewName": "Foo"
},
"Bar_ef49f92628083fab6e14545c18871839": {
"ViewId": "Bar_ef49f92628083fab6e14545c18871839",
"ViewName": "Bar"
}
}
}
In JMeter I use the JSON Extractor with the following expression to find the ViewId value of the element with the ViewName Bar.
$.ReturnData[?(#.ViewName == 'Bar')].ViewId
But this isn't working, the variable is empty.
When i write something in the default values field, that value is used so the script part is correct.
I tried a few online jsonPath expression tools and all return the correct value but JMeter doesn't.
Does JMeter use some special syntax here, am i missing something or is there another way to achieve this?
Ok i found the solution.
$.ReturnData.*.[?(#.ViewName=='Bar')].ViewId
This works as expected.
Btw i found the JSON Path Tester in JMeter which helped a lot.
I still don't understand why the online tools worked but anyway, i'm happy this works now.
I have a response like below-
"distributionChannelList":[
{
"id":1,
"description":"Agency1"
},
{
"id":5,
"description":"Agency2"
},
{
"id":4,
"description":"Agency3"
},
{
"id":3,
"description":"Agency4"
}
],
"marketingTypeList":[
{
"id":1,
"description":"Type1".......
There are so many 'id' and 'description' values in my response. Agency1, Agency2.. are drop downs in my application.
So I want Jmeter to pick a different agency every time and pass in subsequent requests.
How to achieve this?
Use json extractor or reg Ex to fetch all the description with Match No. as 0 for random. Pass the Json created variable to the next request like ${varDescription}. On every run, random value will be fetched and provided to the next request.
Below snapshot is an example for regex but prefer json in your case. For fetching with json use $..description as json path expression. Repeat the same for others if required.
Hope this helps.
Update:-
Please check the below config. It will extractor 2 values in sync. But, ${cnt} should be same value. I have used counter just for demo. You can use random function to generate value between 1 to 4 and pass that variable ${rnd};${rnd}.
I wish to use the JoltTransformJSON spec that can be used to convert the input to output.
I have tried to use map to List and other syntax, but was not been successful so far.
Expected input:
{
"params": "sn=GH6747246T4JLR6AZ&c=QUERY_RECORD&p=test_station_name&p=station_id&p=result&p=mac_addresss"
}
Expected output:
{
"queryType": "scan",
"dataSource": "xyz",
"resultFormat": "list",
"columns": ["test_station_name", "station_id", "result", "mac_address"],
"intervals": ["2018-01-01/2018-02-09"],
"filter": {
"type": "selector",
"dimension": "sn",
"value": "GH6747246T4JLR6AZ"
}
}
Except for the content inside Columns and dimension and value attributes rest of the fields are hardcoded.
As all of the data is contained in a single JSON key/value, I don't think JoltTransformJSON is the best option here. I actually think writing a simple script in Python/Groovy/Ruby to split the querystring value and write it out as JSON is easier and less complicated to maintain. I would recommend Groovy specifically (you can use the specialized ExecuteGroovyScript processor), as it is the most performant & robust in Apache NiFi and has excellent JSON handling.
I want to extract JSON value based on condition using jmeter from an HTML page.
<!doctype html>
var list_data_obj = [{
"list": [
{
"field1": "123",
"field2": "xyz"
},
{
"field1": "456",
"field2": "abc"
},
{
"field1": "789",
"field2": "asdf"
}
],
"other1": "qwerty",
"other2": "asdfgh"
}]
</html>
have tried JSON Path Extractor as below but returned NULL.
$.list[?(#.field2 == 'abc')].field1
Thanks
You won't be able to use JSON Path Extractor as response data is not a valid JSON, it looks like a mix of HTML and JavaScript therefore you will need to use Regular Expression Extractor instead.
The relevant Regular Expression will look like:
"field1": "(.+?)",\s.*"field2": "abc"
References:
JMeter: Regular Expressions
Using RegEx (Regular Expression Extractor) With JMeter
Perl 5 Regex Cheat sheet
The key is to first extract a valid json using a regular expression, then apply a json path extractor on the previously extracted json.
You can perform a 2-step extraction to do this:
First Extract the Json from the page by performing a regexp extractor with "list": ([^^]+}\]), group $1$,
Then perform a Json Extractor on the extracted variable by selecting JMeter variable, then apply your json path $.list[?(#.field2 == 'abc')].field1.
