Looks like pause at the end of scenarios is not considered

Gatling (Open-Source)
1

one of my performance test is : There are 10 employees in a company
each one’s scenario is search (using http POST) read it for 10 sec (pause) , then repeat this for 2 min

for this i have used closed Injection with 10 constant concurrent users for 2 min duration

2 min = 2 * 60 sec . ie., 120 sec. since there is 10 sec pause . the max number of requests each user can achieve is 12 . hence the total number of requests should be < 120 . but Gatling has sent more than 2400 requests in 2 min for 10 concurrent users

please let me know what is wrong here. is pause considered when kept at the end of scenario?

in case you need code :

ScenarioBuilder scn = scenario(
				"Load Test Recommendation Query - " + testData.get(NumberOfUsersKey) + " Concurrent users")
						.feed(searchQueryFeeder).feed(getAuthTokenFeed())
						.exec(RecommendationControllerApi.getFreeTextRecommendationUsingPOST()
								.getGatlingRequest("Recommendation FreeText CU " + testData.get(NumberOfUsersKey))
								.body(StringBody(ftr))
								.header(SainapseUserManagement.authorisationHeaderName,
										"#{" + SainapseUserManagement.authorisationHeaderName + "}")
								.check(status().is(200)))
						.pause(Duration.ofSeconds(pauseInSeconds));

		this.setUp(scn.injectClosed(constantConcurrentUsers((Integer) testData.get(NumberOfUsersKey))
				.during(Duration.ofMinutes((Integer) testData.get(SimulationTimeKey))))).protocols(httpProtocol);

The run duration is based on the instant of the last response, but except that, I can assure that virtual users consider pauses whatever their location, even as the last action.

kindly elaborate on

  1. why number of total requests is > 120
  2. how can i achieve <=120 total requests

As requested here, please provide a reproducer we can run on our side.

So the issue is on your side.
Are you sure you don’t have tons of redirects?

This indeed is my code issue…
