    Performance Testing Interview Questions
    JMeter Interview Questions
    Hi Raghav.
    Have one query.
    Today I have given one interview for performance with Jmeter.
    The interviewer asked me how we will do end to end performance testing. ?
    How to convince a client that performance testing is necessary for you.
    How to test with 1000 user, what all approaches to follow?
    Can you give me answers to all these
    Please help
    Thanks
    Utkarsh
    _________________________________________________
    How we will do end to end performance testing?
    First thing will be to clarify on what is meant by end-to-end performance testing and what is in scope.
    So first you will create a plan as per the in-scope items.
    Scope | Expected Load | Geographical distribution |
    You will need a separate env for performance testing.
    Will analyze and take up the modules/scenarios where performance needs to be checked most.
    While setting up performance test you will need information on:
    min, max, avg load expectations.
    geographical distribution
    You can start with Network API calls test and can go to UI level.
    How to convince the client that performance testing is necessary for you?
    Here if you can provide some specific and generic examples, that will help you.
    Usually, in an organization, examples are given of past projects where performance testing helped to make the application efficient and helped to avoid performance issues in production.
    You can also give some ROI calculation like with Automated performance testing you can create 1000's of virtual users and can test the impact without creating a costly infrastructure.
    How to test with 1000 user, what all approaches to follow?
    We never start directly with max user load.
    First, create a sample test plan and test it with single or max 10 users.
    Get it approved and then increase the count gradually.
    Also ensure this test is performed on a separate environment, so not to compromise on any existing env in use by other teams.
    After this, you should run your tests for 100 users, 200, 500, 700, 1000 etc. This no can vary based on application performance and infrastructure.
    You should also get some SLA for comparison of your results. Else you need to create a baseline first and then compare your subsequent results with this baseline.
    Suppose you get a huge time with 100 users on some request which is not expected, then you can share the results and ask if you should proceed with more users or wait until the issue is fixed.
    So overall, Utkarsh, you have to show your experience and observation skills here. No one is expecting a perfect answer (most of the cases the other person also does not know it).
    You should know what you speak as there can be a counter question.
    With experience, you will know it all.

    Hi Raghav Sir,
    Your videos are very nice and comprehensive. I have a question related to API testing and this has been asked to me by many of the interviewers. Question is " There are 2 APIs and the functionality is from one API some random sets of data (say 10000 or 100000 records) would be send to another API one by one. How would be perform the testing on it. Please have a look and answer this question. Would be helpful if you can share the solutions through both Jmeter as well as Postman.

    • @RaghavPal
      @RaghavPal  4 роки тому

      Hi Akash, in general API do communication between two apps and works on request response model. Now ideally, in this scenario, you may ask more clarifications like what do you mean by one by one. Is this request and response automated or a triggered response, like I hit the first API and then it keeps on sending response to second api again and again.
      The other things we need to check is how exactly is this response data received or what's the format, if it is JSON we can use a JSON parser and parse and use data as we need, If it is XML can use an XML parser and so on.
      Let me know if you have understood this,

    Hi Raghav, I was asked this question in an interview "What is Throughput in JMeter and how to explain it to a client who doesn't have technical knowledge.

    • @RaghavPal
      @RaghavPal  2 роки тому +2

      Hi Divya,
      Throughput is calculated as requests/unit of time
      The time is calculated from the start of the first sample to the end of the last sample
      This includes any intervals between samples, as it is supposed to represent the load on the server.
      The formula is:
      Throughput = (number of requests) / (total time)
      The higher the Throughput is, the better is the server performance

    • @RaghavPal
      @RaghavPal  3 роки тому +3

      Hi Jumi, I will plan a session.
      in general some other good practices
      1. Always do performance testing on a separate env. Create a sep env which will not be used for other activities
      2. Run your tests with the same infrastructure, network stats etc. To get consistent results and can be compared with the baseline
      3. Create more realistic test - have some think time between requests
      4. Add ramp up time, Do not start directly with 500 users
      5. Always have a baseline to compare your test against.
      6. JMeter checks the server performance and does not care for browser render time. So if you see your jmeter results are good but your application is still slow. Check for client-side performance testing tools
      7. Focus on the areas that needs performance testing based on user scenario
      8. Always document your results

      Hi Faizan, ideally it should be based on your experience, however few general challenges people face in performance testing are
      1. Setting up the correct environment for performance testing
      2. Setting up benchmarks
      3. Running tests with same environmental factors for consistent results
      4. Collecting and managing results for better analysis
      5. Infrastructure management

    • @RaghavPal
      @RaghavPal  3 роки тому +3

      Hi Anshita, in general for testing the performance of any application we start with a general load test where we test the application with multiple virtual users, and then based on the output and needs we can plan other tests like stress, endurance etc. It also depends of the application type, use, scenario, for e.g. we have some e-commerce app like amazon or flipkart, on some specific day we have a big sale and we know that there will be much more traffic than normal days and therefore we have to test the entire system for that accordingly

      Hi Anshita, sometimes it also depends on the client requirements, if they want us to run multiple different kinds of performance tests for an application.It also depends on what exactly they would like to see by doing different kinds of tests and then for us to observe and analyse the different metrics post test completion and then based on the test report we give them, they can understand a lot about the application behaviour and also how they can possibly improve the end users experience

      Hi Raj, In PT, you need to create a baseline and check all results against the baseline. So you can setup the baseline on the env available and then run your tests and compare. In case it is not a separate PT env. you may have to see that you carry out your testing at time when its not being used to rule out any noises

      Hi Atul, this will be a very generic data to predict users, as the threads (users) increases we cannot predict the behaviour in linear terms. We have to get requirements in terms of sla on avg response times, resource utilization limits etc and then divide our tests in section like 0-10 users 10-50, 50-100 etc. This can change based on needs and then setup your performance test

      Response time: The time it takes for the application to respond to a user's request. This is typically measured in milliseconds and should be as low as possible to provide a good user experience.
      Throughput: The number of requests that the application can handle per unit of time. This is usually measured in requests per second (RPS) or transactions per second (TPS).
      Latency: The time it takes for a request to be processed by the application and a response to be returned. This is usually measured in milliseconds and should be as low as possible to provide a good user experience.
      Availability: The percentage of time that the application is accessible and usable by users. This is usually measured as a percentage of total time and should be as close to 100% as possible.
      Error rate: The percentage of requests that result in an error. This is usually measured as a percentage of total requests and should be as low as possible.
      Resource utilization: The amount of resources, such as memory and CPU, that the application is using. This should be monitored to ensure that the application is running efficiently and to prevent resource depletion.
      These metrics can be used as a starting point for evaluating the performance of your SaaS application, but the specific values or targets for each metric will depend on the requirements and use cases of your application. It's important to monitor performance regularly and continuously improve it over time to ensure a good user experience

      @RaghavPal  5 років тому

      Hi Viji, This can be specific to your work and experience, If you ask me something that I can explain is.. While working on Continuous Integration on Jenkins, I had a need to integrate the testing jobs with dev build jobs, I did the same by chaining the jobs, However, we needed a comprehensive report or overview of multiple runs over a time. This was a bottleneck and after doing some analysis and research got to knwo about pipeline plugins in Jenkins and used the same to handle this scenario.
      Now, this is a scenario specific to my experience, You should think something that you have witnessed and handled.

      Hi,
      I think i am qualified to answer this question.
      Bottle neck is nothing but application's strange behavior or problems and issues which are actually in hidden nature.
      Being a performance tester i have found the many bottle neck of the application while doing the performance testing.
      How : while executing the performance test plan you need to monitor the tools like app insight and Db monitoring tool. These tools to help you to find out the bottle neck.
      What I found: deadlocks in db.
      I have found that deadlocks are happening frequently once load is crossed 50. This happed because of the the flat table implementation issue.
      Conclusion : only performance testing can identify the hidden bottlenecks.
      Thank you 😊

    • @RaghavPal
      @RaghavPal  9 місяців тому

      To hit your BlazeMeter recorded scripts in Postman, you can follow these steps:
      1. **Import the BlazeMeter scripts into Postman.**
      You can import your BlazeMeter scripts into Postman by exporting them from BlazeMeter and then importing them into Postman. To export the scripts from BlazeMeter, follow these steps:
      1. Go to the BlazeMeter recorder.
      2. Select the scripts that you want to export.
      3. Click on the **Export** button.
      4. Select **Postman** as the export format.
      5. Click on the **Export** button.
      To import the scripts into Postman, follow these steps:
      1. Open Postman.
      2. Click on the **File** menu and select **Import**.
      3. Select the BlazeMeter script file that you exported.
      4. Click on the **Import** button.
      2. **Update the request parameters.**
      Once the scripts have been imported into Postman, you may need to update the request parameters. This is because the BlazeMeter recorder may generate request parameters that are not compatible with Postman.
      To update the request parameters, follow these steps:
      1. Open the request that you want to update.
      2. Click on the **Params** tab.
      3. Update the request parameters as needed.
      3. **Run the requests.**
      Once the request parameters have been updated, you can run the requests by clicking on the **Send** button.
      If you are getting 100% errors in the JMeter summary report, then it is likely that there is a problem with the BlazeMeter scripts. You can try to troubleshoot the problem by checking the following:
      * Make sure that the BlazeMeter scripts are valid.
      * Make sure that the request parameters are correct.
      * Make sure that the target server is reachable.
      If you are still having problems, then you can contact BlazeMeter support for help.
      Here are some additional tips for hitting BlazeMeter recorded scripts in Postman:
      * You can use the **Pre-request Script** and **Post-request Script** features in Postman to automate tasks such as logging in to the target server and clearing cookies.
      * You can use the **Collection runner** feature in Postman to run multiple requests in sequence.
      * You can use the **Monitor** feature in Postman to track the performance of your requests.
      By following these tips, you can easily hit your BlazeMeter recorded scripts in Postman and troubleshoot any problems that you may encounter.
