JMeter lets you create these assertions using regular You could add assertions to check for certain HTML tags,Ĭommon error strings, and so on. May return a successful "HTTP Response" code, but the page may have errors on it or For example, in stress testing a web application, the server The response of your request, add an Assertion to If you are interested in having JMeter perform basic validation on Remember to add a Listener to your test plan to view and/or store the Each controller has one or more Defaults elements (see below). HTTP Request) to the same server, consider using a Defaults ConfigurationĮlement. If you are going to send multiple requests of the same type (for example, You can further customize a sampler by adding one or more Configuration Elements to the Test Plan. HTTP Request (can be used for SOAP or REST Webservice also)Įach sampler has several properties you can set.They are processed in the order they appear in the tree.Ĭontrollers can be used to modify the number of repetitions of a sampler. Samplers tell JMeter to send requests to a server and wait for a response. Of the Thread Group and run for the configured Duration (seconds) time. When the test is started, JMeter will wait Startup Delay (seconds) before starting the Threads The duration of each thread group and the after how much seconds it starts. You can configure Duration (seconds) and Startup Delay (seconds) to control In which you can enter the duration of test and the startup delay Thread Group also allows to specify Thread lifetime.Ĭlick the checkbox at the bottom of the Thread Group panel to enable/disable extra fields Start with Ramp-up = number of threads and adjust up or down as needed.īy default, the thread group is configured to loop once through its elements. The first ones finish (unless one wants that to happen). Of a test, and short enough that the last threads start running before Ramp-up needs to be long enough to avoid too large a work-load at the start If there are 30 threadsĪnd a ramp-up period of 120 seconds, then each successive thread will be delayed by 4 seconds. Start 10 (100/10) seconds after the previous thread was begun. JMeter will take 100 seconds to get all 10 threads up and running. If 10 threads are used, and the ramp-up period is 100 seconds, then The ramp-up period tells JMeter how long to take to "ramp-up" to the full number of Multiple threads are used to simulate concurrent connections Set the number of times to execute the testĮach thread will execute the test plan in its entirety and completely independently.TheĬontrols for a thread group allow you to: In which case they will apply to all the thread groups.Įlement controls the number of threads JMeter will use to execute your test. Listeners, may be placed directly under the test plan, spawn(threadsCount, initalDelay, startupTime, holdLoadFor, shutdownTime) - spawns specified threads number and configures start time, ramp-up time, flight time and shutdown timeĭuration values (initialDelay, startupTime, holdLoadFor, shutdownTime) may be specified with shorthand, case-insensitive modifiers:ĭuration setting may be combined like 1d11h23m6s.Thread group elements are the beginning points of any test plan.Īll controllers and samplers must be under a thread group.Schedule is specified with a list of spawn directives: Property can be specified either in user.properties file (jmeter.properties also applicable), orįrom command line like -J "threadsschedule=."_. There is a way to configure thread group from special jmeter property threadsschedule_. Look how predictable our active threads graph is: Let's configure Ultimate Thread Group as following:Īnd then try to run test. and, of course, trustworthy load preview graph.separate ramp-up time, shutdown time, flight time for each schedule record.The features that everyone needed in JMeter and they finally available: "Ultimate" means there will be no need in further Thread Group plugins.
