JMETER: Not able to add Cookie to request

Question

First time poster, long time reader - For one of my Performance tests, a cookie is not being passed for one of the requests. I have been trying many of the suggestions that I found here and other places online and I still cant seem to manually add a cookie to any request.

So what I am trying to do now is just follow the sample from Blazemeter and even with my basic setup, I still can't get the cookie added. I have to be missing something easy and I am running out of hair to pull out.

(I can't post pics yet, so image link is below)

Jmeter version - 5.0 r1840935

User.Properties Updated -

CookieManager.check.cookies=false
CookieManager.save.cookies=true

I have the HTTP Cookie Manager at the ThreadGroup Level. The cookie policy is set to standard, but I also tried to use Default with no difference. The HTTP Request has following settings: serverName: blazedemo.com, Method:GET, Path:password/reset

In the JSR223 Preprocessor (Groovy 2.4.15 / Groovy Scripting 2.0) under the HTTP request, my code looks like the following (with some debug statements)

 import org.apache.jmeter.protocol.http.control.CookieManager;
import org.apache.jmeter.protocol.http.control.Cookie;

//Get cookie manager
CookieManager cm = ctx.getCurrentSampler().getCookieManager()
Cookie cookie = new Cookie("sampleCookie", "sample", "opencart.abstracta.us", "/Mytest/done", false, 1557578515)
cm.add(cookie)
Cookie c=cm.get(0)
log.info("*********Cookie #3:" + c.getName() + "cookie value: " + c.getValue())
log.info("******************** Cookies count: " + cm.getCookieCount())

The Jmeter debug log shows the following so it appears that the cookie is successfully added to the store and I think it should work.

2020-01-22 19:10:35,936 DEBUG o.a.j.p.h.c.CookieManager: **Add cookie to store** opencart.abstracta.us  TRUE    /Mytest/done    FALSE   1557578515  sampleCookie    sample
2020-01-22 19:10:35,936 INFO o.a.j.m.JSR223PreProcessor: *********Cookie #3:sampleCookiecookie value: sample
2020-01-22 19:10:35,936 INFO o.a.j.m.JSR223PreProcessor: ******************** Cookies count: 1

However, the log also shows that there were no cookies found for the request -

2020-01-22 19:10:35,938 DEBUG o.a.j.p.h.c.HC4CookieHandler: Found 0 cookies for http://blazedemo.com/password/reset

When looking at the Request Body, I see the following:

GET http://blazedemo.com/password/reset
GET data:
[no cookies]

I don't see a syntax error, but do I have something setup incorrectly? If I add a cookie to the Cookie Manager in the 'User-Definied Cookies' that cookie is indeed passed along to the request.

After taking another look at it this morning, It seems that I had the HOST incorrect. the cookie wasn't being added due to that issue. I think was just a bit tired last night! — TYale

You're adding the cookie for domain opencart.abstracta.us and path /Mytest/done
You're hitting the domain blazedemo.com and path /password/reset
You're expecting to see the cookie in the request - this will not happen

According to RFC 6265 this behaviour is absolutely expected, if you want to see the programmatically generated cookie - it's domain and path must match the domain/path in the HTTP Request sampler

So change this line:

Cookie cookie = new Cookie("sampleCookie", "sample", "opencart.abstracta.us", "/Mytest/done", false, 1557578515)

to this one:

Cookie cookie = new Cookie("sampleCookie", "sample", "blazedemo.com", "/password/reset", false, 1557578515)

and your scenario should start working as expected.
