Most of us things that ppl r born smart, but truth is 99% of the smartest ppl n this world are driven by commitment to learn, learn and learn more.Learn more and share more 🙂 Fb,G+,Twitter
1.Test plan :- Container for running the tests. Its the starting point, by default jmeter opens up with test plan.
2.Users(called as Thread Group in JMeter) :- How many users should be involved in sending the request to the server, how often, and ramp up time.
Why this ? it mimics the interaction of real users with the application at given time.
3.Task( what type of request that needs to be send to server, called as Samplers):-For example if we want to access the google.com we are sending http request thus we need a particular type of sampler called http request sampler. If we are sending request to database we make use of jdbc sampler.
Note:- JMeter sends request to server based on the order they appear in the tree.
4.Assertions:– Verify the response send by server, comparing the actual value with expected value.
5.Report(called as Listeners in JMeter):- Request is send to server how to report the results for the response, we use Listeners for this.
Solution:- Lets create a pipeline for the above steps,
ThreadGroup (We created users) > Samplers (users send request to server) > Assertions (Verify the response for the request) > Listeners (Report the response results as graphs, table and so on).
Step2:-Add thread group
Note:- We have renamed the test plan in our example below.
Right click Test Plan > Add > Thread(Users) > Thread Group
Rename Thread group to something logical.
Change the thread properties like number of users.
Right click Thread Group > Add > Sampler > HTTP Request
Rename it something logical
Define user defined variables for a test plan (FirstTestCaseJMeter) .
- Open test plan
- click on Add
- Enter name and value
Note:-Incase we need to pass any parameters or body elements we can do it here.
Step4:-Assertions (say to check 200 status code)
Right click Thread Group > Add > Assertions > Response Assertion
Select ReponseCode and Equals, put value as 200
Step5:-Listeners (Report the run results)
Right click Thread Group > Add > Listener > View Result Tree
Step6:-Run the test plan
Before running we need to save the .jmx file
Ways to run :-
- Run > Start
- Ctrl + r
- Green play button on the menu bar
Step7:-Check the run results
Select View Result Tree
Its green, means our assertion is successful and we got the response back 🙂
So we successfully created the basic test plan in jmeter. To explore more change the listener type, add more users and add different type of assertions.
