I am uploading a file via API for which I do a ‘polling’ and have the following 2 steps / transactions:
HTTP request to upload it for which I get a temporary status response ‘uploading’
While loop with a counter until the response status changes to ‘success’ but not more than 10 times.
${__javaScript("${STATUS}" != "success" && ${counter} < 10,)}
Question-1: How do I measure the response time for step-2 as it varies (sometimes, file will be uploaded in 2 times and sometime in 8 times)?
Question-2: How to make step-2 fail when the status has not changed to success even after all 10 iterations/ attempts?
Please could someone help?
Thanks,

Put everything under Transaction Controller, it will measure duration of all the iterations.
You can go for JSR223 Assertion, example code would be something like:
if (vars.get('counter') == '9' && vars.get('STATUS') != 'success') {
AssertionResult.setFailureMessage(true)
AssertionResult.setFailureMessage('Status is ' + vars.get('STATUS') + ' after ' + vars.get('counter') + ' iterations')
}
put it as a child of the 2nd request and if after 10 iterations the status won't be success it will mark the sampler as failed.

I am using JMeter Webdriver sampler for the application UI response time measurement. I am facing issue with the wait function. For example the login page loads between 10 to 120 secs. So I have the following code for the login page in Webdriver sampler for the page load check.
var ui=JavaImporter(org.openqa.selenium.support.ui)
var wait=new support_ui.WebDriverWait(WDS.browser,120)
wait.until(ui.ExpectedConditions.visibilityOfElementLocated(pkg.By.className('logout-btn-hover')))
The issue is even after the page load completely, JMeter is still waiting to perform the next action. This waiting time will reduce if I reduce the 120 secs.But sometimes the application will take 120 secs to load also so I need to keep 120 secs.
I am writing the time to a log file once the sampler completes its action. Because of the wait time issue I am not able to calculate time properly.
There are at least 2 errors in your script, it should look something like:
var ui=JavaImporter(org.openqa.selenium.support.ui)
var wait=new ui.WebDriverWait(WDS.browser,120)
wait.until(ui.ExpectedConditions.visibilityOfElementLocated(org.openqa.selenium.By.className('logout-btn-hover')))
Check out jmeter.log file for any suspicious entries, in particular for something like:
ERROR c.g.j.p.w.s.WebDriverSampler: Expected condition failed: waiting for visibility of element located by By.className: logout-btn-hover (tried for 120 second(s) with 500 milliseconds interval)
Double check your CSS selector
Consider refactoring your code to look for the logout button(?) in a loop with verbose logging for each step. Sample code:
var pkg = JavaImporter(org.openqa.selenium)
WDS.sampleResult.sampleStart()
WDS.browser.get('http://example.com')
var start = new Date().getTime()
var attempt = 1
while (new Date().getTime() - start < 5000) {
try {
var logout = WDS.browser.findElement(pkg.By.className('logout-btn-hover'))
WDS.log.info('Element found')
break
}
catch (err) {
WDS.log.info('Attempt # ' + attempt + ', Element not found')
java.lang.Thread.sleep(1000)
attempt++
}
}
WDS.sampleResult.sampleEnd()
Example output when the element is not found:

Error I get when I try to send HTTP response with big json string response (json_response)
PANIC: unprotected error in call to Lua API (file.lua:5: out of memory)
Code:
-- a simple HTTP server
srv = net.createServer(net.TCP)
srv:listen(80, function(conn)
conn:on("receive", function(sck, payload)
sck:send("HTTP/1.0 200 OK\r\nContent-Type: text/html\r\n\r\n"..json_response)
end)
conn:on("sent", function(sck) sck:close() end)
end)
Yes, that won't work if you're trying to send a lot of data. You need to send this piece-by-piece. Our API documentation shows two approaches (you would find further references here on SO) the first being this:
srv = net.createServer(net.TCP)
function receiver(sck, data)
local response = {}
-- if you're sending back HTML over HTTP you'll want something like this instead
-- local response = {"HTTP/1.0 200 OK\r\nServer: NodeMCU on ESP8266\r\nContent-Type: text/html\r\n\r\n"}
response[#response + 1] = "lots of data"
response[#response + 1] = "even more data"
response[#response + 1] = "e.g. content read from a file"
-- sends and removes the first element from the 'response' table
local function send(localSocket)
if #response > 0 then
localSocket:send(table.remove(response, 1))
else
localSocket:close()
response = nil
end
end
-- triggers the send() function again once the first chunk of data was sent
sck:on("sent", send)
send(sck)
end
srv:listen(80, function(conn)
conn:on("receive", receiver)
end)
How can I get an overall PASS/FAIL result for a JMeter thread group without using a post processor on every sampler?
I've tried using a beanshell listener, but it doesn't work for instances where there are multiple samplers inside a transaction controller with "Generate Parent Sample" enabled. In that case, the listener only gets called once per transaction controller and I'm only able to access the result of the last sampler inside the transaction controller.
Edit:
I would like to be able to save a pass/fail value as Jmeter variable or property for the thread group. If one or more components of the thread group fail or return an error, then that would be an overall fail. This variable will then be used for reporting purposes.
My current beanshell listener code:
SampleResult sr = ctx.getPreviousResult();
log.info(Boolean.toString(sr.isSuccessful()));
if (!sr.isSuccessful()){
props.put("testPlanResult", "FAIL");
testPlanResultComment = props.get("testPlanResultComment");
if(testPlanResultComment == ""){
testPlanResultComment = sr.getSampleLabel();
}else {
testPlanResultComment = testPlanResultComment + ", " + sr.getSampleLabel();
}
props.put("testPlanResultComment", testPlanResultComment);
log.info(testPlanResultComment);
}
If you call prev.getParent() you will be able to fetch individual sub-samples via getSubResults() function, something like:
prev.getParent().getSubResults().each {result ->
log.info('Sampler: ' + result.getSampleLabel() + ' Elapsed time: ' + result.getTime() )
}
log.info('Total: ' + prev.getParent().getTime())

I use Github API V3 to get forks count for a repository, i use:
GET /repos/:owner/:repo/forks
The request bring me only 30 results even if a repository contain more, I googled a little and I found that due to the memory restrict the API return only 30 results per page, and if I want next results I have to specify the number of page.
Only me I don't need all this information, all I need is the number of forks.
Is there any way to get only the number of forks?
Because If I start to loop page per page my script risque to crash if a repository contain thousand results.
You can try and use a search query.
For instance, for my repo VonC/b2d, I would use:
https://api.github.com/search/repositories?q=user%3AVonC+repo%3Ab2d+b2d
The json answer gives me a "forks_count": 5
Here is one with more than 4000 forks (consider only the first result, meaning the one whose "full_name" is actually "strongloop/express")
https://api.github.com/search/repositories?q=user%3Astrongloop+repo%3Aexpress+express
"forks_count": 4114,
I had a job where I need to get all forks as git-remotes of a github project.
I wrote the simple python script https://gist.github.com/urpylka/9a404991b28aeff006a34fb64da12de4
At the base of the program is recursion function for getting forks of a fork. And I met same problem (GitHub API was returning me only 30 items).
I solved it with add increment of ?page=1 and add check for null response from server.
def get_fork(username, repo, forks, auth=None):
page = 1
while 1:
r = None
request = "https://api.github.com/repos/{}/{}/forks?page={}".format(username, repo, page)
if auth is None: r = requests.get(request)
else: r = requests.get(request, auth=(auth['login'], auth['secret']))
j = r.json()
r.close()
if 'message' in j:
print("username: {}, repo: {}".format(username, repo))
print(j['message'] + " " + j['documentation_url'])
if str(j['message']) == "Not Found": break
else: exit(1)
if len(j) == 0: break
else: page += 1
for item in j:
forks.append({'user': item['owner']['login'], 'repo': item['name']})
if auth is None:
get_fork(item['owner']['login'], item['name'], forks)
else:
get_fork(item['owner']['login'], item['name'], forks, auth)
I am currently trying to modify a plugin for posting metrics to new-relic via AWS. I have successfully managed to make the plugin post metrics from swf to new relic (not originally in plugin), but have encountered a problem if the program runs for too long.
When the program runs for a bout 10 minutes I get the following error:
Error occurred in poll cycle: Rate exceeded
I believe this is coming from my polling swf for the workflow executions
domain.workflow_executions.each do |execution|
starttime = execution.started_at
endtime = execution.closed_at
isOpen = execution.open?
status = execution.status
if endtime != nil
running_workflow_runtime_total += (endtime - starttime)
number_of_completed_executions += 1
end
if status.to_s == "open"
openCount = openCount + 1
elsif status.to_s == "completed"
completedCount = completedCount + 1
elsif status.to_s == "failed"
failedCount = failedCount + 1
elsif status.to_s == "timed_out"
timed_outCount = timed_outCount + 1
end
end
This is called in a polling cycle every 60 seconds
Is there a way to set the polling rate? Or another way to get the workflow executions?
Thanks, here's a link to the ruby sdk for swf => link
The issue is likely that you are creating a large number of workflow executions and each iteration through the loop in workflow_executions is causing a lookup, which eventually is exceeding your rate limit.
This could also be getting a bit expensive, so be careful.
It's not clear what you're really trying to do, so I can't tell you how to fix it unless you post all your code (or the parts around calls to SWF).
You can see here:
https://github.com/aws/aws-sdk-ruby/blob/05d15cd1b6037e98f2db45f8c2597014ee376a59/lib/aws/simple_workflow/workflow_execution_collection.rb
That a call is made to SWF for each workflow in the collection.
