Reading payload from tsv file

Gatling (Open-Source)

Hi,

I am new to Gatling. I am writing a test scenario where I want to read payload for each of the POST request from a tsv file. My tsv file looks something like this:

flags

{"“payload”: {“Id”: “D85B24305BA511E3949A0800200C0000”,“a1”: “5A0C96845BA611E3949A0800200C0000”,“a2”: “S12”,“a3”: “S22”,“a4”: “INTERNAL”"}}

My scenario code looks like this:

val scn = scenario(name)

.feed(tsv(fileName).circular)

.exec(

http(name)

.post(url)

.body(StringBody("${flags}"))

.asJSON

.headers(headers)

.check(status is 200)

But I am getting 400 bad request. Am I doing anything wrong?

You probably didn’t properly escaped your JSON body according to the CSV spec: http://tools.ietf.org/html/rfc4180#section-2
See 2.4 to 2.6.

If your JSON is { “foo”: “bar” }, then you have to write in your CSV so it’s properly decoded: “{ “foo”: “bar” }”

FYI, there’s a new feature that let one perform a simple split instead of a full CSV parsing: https://github.com/excilys/gatling/issues/1937

So looks like it is able to read the file (console log shows so) but I am not sure if it is setting it properly in the request. I tried using

param is ONLY for form upload.
What you need is probably body.

Then, please take my previous explanations into account.
