How to make several requests be made once? And the rest flow - jmeter

I have 2 queries and a db connection that i would like to make once as part of testing
CSRF
DB CONNECT
LOGIN
And then comes the API method I need that I'm testing. Here it needs to be run a number of times.
I read the documentation, but I still don't understand. Please help.

Put them under the Once Only Controller, its children are being executed only during the 1st iteration of the Thread Group
I also see a number of Listeners in your Test Plan, when you finish test development and debugging don't forget to remove them as they don't add any value and only consume resources, you should execute your JMeter test plan in command-line non-GUI mode with all listeners disabled or deleted and once it's finished you can use Listeners to analyze the .jtl results file (or just generate HTML Reporting Dashboard from it)

Not able to add data for 50 users using Jmeter

Executed load testing script using JMeter for 50 users but it is not adding data in database for 50 users and adding only for 20 users, What is the issue?
Open your .jtl reusults file with a listener like Aggregate Report and check the number of failures, if it's around 40% - then you need to investigate the cause of the failures and see what needs to be done to fix them either from JMeter or from application under test perspectives.
If there are no failures in the .jtl file but your test is not doing what it is supposed to be doing - most probably it "silently" fails somewhere somehow. I would recommend adding Response Assertions to each and every step to validate that each response contains the anticipated data (or alternatively doesn't contain errors).
JMeter automatically treats HTTP status codes below 400 as successful and doesn't do any other checks so in case when an error occurs but application responds with a positive HTTP status code JMeter will consider the request as passed so you need to specify pass/fail criteria.
And last but not the least, you can temporarily amend the Results File Configuration so JMeter would store all the request/response details, after test run you will be able to examine the flows using View Results Tree listener and identify where and how exactly your script does fail.

JMeter - Execute multiple test plans from single console

I am new to JMeter. I have created several test plans. Is it possible to combine different test plans in a single '.jmx' file so that the user can see all the different test plans in one console? Not only that, the user can pick and choose more than one test plans and run them? The test plans may not be collaborating with each other. Theyare completely isolated test plans. The idea is, the user can view and execute them from one console?
First of all, looking into Adding and Removing Elements chapter of Building a Test Plan article:
Adding elements to a test plan can be done by right-clicking on an element in the tree, and choosing a new element from the "add" list. Alternatively, elements can be loaded from file and added by choosing the "merge" or "open" option.
You can also store multiple .jmx scripts as Test Fragments and add them to the "main" script via Include Controller and/or Module Controller
Check out How to Manage Large JMeter Scripts With JMeter Test Fragments article for more information.
instead of maintaining multiple test plans .. i would suggest make multiple thread groups in one test plan so whoever going to use specific group then can enable and run ..
I am not sure you can add multiple test plans in one JMX file, as above comment says you can create multiple Thread groups in one test plan.
You can even create a test plan with JDBC request to test Data base and another test plan with Http request to API tests.
Add different headers and Listeners in each thread group as needed.
If you want aggregate report of all thread groups, you can listener by right clicking on Test Plan.

JMeter test report

I'm using JMeter for integration and non-regression testing.
The tests are automated and reports are working.
But since it is scenario testing and not performance testing the report doesn't give real business added value for that kind of tests.
My question: Is there any way to have a scenario (transaction controller based)reporting?
For the moment, to have some more meaningful result, transactions controllers and dummy sampler are used.
What we would like to have is the number of success/failure scenarios of the last test run. And also an history of success/failures per test run (1 by day).
Thank you for your advices.
The easiest way of getting the things done is putting your JMeter test under Jenkins orchestration so it will be automatically executed based on a VCS hook or according to the Schedule
Once done you will be able to utilize Jenkins Performance Plugin which adds test results trends charts and ability to mark build as unstable/failed depending on various criteria.
If I am not wrong, you want to create a suite based on particular test cases. like if single case include execution of more than 1 request in a single execution.
If this is the case, you can simple create a test fragment through jmeter gui, and copy all the samplers in single fragment.
Now to control their execution you can use any controller of your choice, i would suggest you to use module controller for http samplers.

Performance testing with Jmeter

I've recorded a test script of web application (extJS). The test logs into application (I used login and password saved in .txt file and CSV Data Set Config element), makes some calculations with external webservice and adds some elements to database. It works fine but...
I'm not sure that all of my users do these things at the same time... Is there any way to configure it?
E.g 100 users do the same scenario at the same time?
You can see the exact number of concurrent users via Active Threads Over Time Listener available via JMeter Plugins
If you're not happy with what you're seeing and expect more concurrent users you can consider 2 options:
Increase "Loop Count" on Thread Group level as when JMeter thread has finished executing all samplers and doesn't have any more to run and no loops to iterate - it's being shut down.
Add Synchronizing Timer. It pauses all the threads until the desired amount is reached and releases them at exactly the same moment so you will be able to test i.e. what happens when 100 users are trying to log in at the same time.

Endurance testing using Jmeter

I am new to Jmeter and trying to understand what all can be achieved using Jmeter. I want to perform endurance or soak testing of a application using Jmeter, i.e. I want to run a particular script for a particluar number of users for a period of 3 hours.
What all options are available to me and what is the best availablelistener to monitor the result?
Please help. Kindly add if I am missing anything that I should know before starting with soak testing?
For setting up the numbers of users and runtime of the test you use a Thread Group. Setting the runtime is done by checking the Scheduler check-box and specifying Duration.
Of the original listeners in JMeter I have found myself most oftenly just using the plain Summary Report. But JMeter Plugins gives additional listeners which may be better, it depends on what you want to measure. The JMeter Plugins also gives additional thread groups, where you can specify e.g. an increasing load over time.
Use a Thread Group to set up your number of users and the duration of your test (using the scheduler of the Thread Group).
Then add all the samplers and logic controllers you need to perform your testing.
Next, add a Summary Report listener to get an overview of your results (min/max/average and such), and add a View Result Tree listener to get an overview of EACH step your testplan is taking. This Tree listener is great to actually see what jmeter is doing, and to debug your tesplan.
BTW: if you add a HTTP Request Defaults object, you can set your URL and options in there, and don't need to add it to each and every sampler again. Especially works like a charm if you start using regexp extractors and such.
