Load testing goals

load testing

Load testing goals are:

CLICK TO READ FIRST PART

  • Response time for each and every transaction
  • Performance of the system components under different loads
  • Performance of database components and their behaviour with different volumes of data
  • The network delay between client and server
  • Software application design issues affecting the performance
  • Server configuration like web server, application server issues

The load testing specifies whether the software needs a fine tuning or modified for hardware and software to improve the performance.

The advantages of load testing are

  • Reduces the cost of failure
  • Improves scalability
  • Increase customer satisfaction

Challenges of load testing:

  • Need of programming knowledge to use load testing tools
  • Tools can be expensive

Load testing is carried out with the varying users to assess ability of the system to work properly. The performance of the software beyond the expected maximum workload can be tested. The load testing tools like HP Loadrunner can be used for testing the different load scenarios by gradually increasing and decreasing the user load on the system.

For eg:

– test the system performance with 50 concurrent users

  • Ramp up(gradual increase in number of users) : 5 users every 2 min
  • Ramp down(gradual decrease in the number of users) : 5 users every 3 mins
  • duration: peak load: 10 mins
  • pacing between iterations: 5 seconds

This kind of scenarios cannot be tested manually because arrangement of resources, controlling  many number of users at a time is impractical

The load testing can be done in many testing cycles with different number of user loads.

For eg:

10 users, 30 users, 40 users, 50 users(peak load)

The main metrics used for load testing:

  • Response time:

The time taken by the system to respond to users request

  • Throughput:

The bytes per run

  • Transaction summary

    2. difference bet load and performance testing:
    A Load testing is a kind of Performance Testing which determines a system’s performance under real-life load conditions. This testing helps determine how the application behaves when multiple users access it simultaneously.
    b. Performance Testing measures the response time of an application with an expected number of users. The aim of this is to get a baseline and an indication of how an application behaves under normal conditions. Does it meet the required response time or not.

  4. Load Testing- is testing the performance of the software with different number of users and thus identifying the maximum number of users supported by the software. It is used for testing web-based applications. Here, multiple users access a site/software simultaneously. With multiple number of users accessing the same website/application, it helps to determine the system performance or site speed by identifying the response time, determine the delay between client and server ,performance of system components, database components, any issues in the configuration of the software,web server issues or application server issues.

    The difference between load testing and stress testing

    Load testing is a planned test to perform a number of requests in order to test the functionality of the system under different levels. The software performance is tested with varying number of users.

    Stress Testing increases the number of requests under the complete system failure. The software performance is tested with varying number of resources.

  8. Load testing goals are:
    -response time of each and every transactions.
    -performance of the different system components under different tools.
    -performance of database components and their behavior with different volumes of data
    -network delay between client and server
    software application design issues affecting the performance

    – Performance of the system components under different loads
    – Performance of database components and their behaviour with different volumes of data
    -The network delay between client and server
    -Software application design issues affecting the performance

    Difference between stress testing and load testing
    A load test is a planned test to perform a specified number of requests to a system in order to test the functionality of the system under specific levels of simultaneous requests. A load test ensures that a web system is capable of handling an expected volume of traffic, and therefore is sometimes referred to as volume testing. The goal of a load test is to prove that a system can handle the expected volume with minimal to acceptable performance degradation. The threshold of acceptable performance degradation must be defined by the testers as some value considered acceptable to the end user so that users will not bounce from the site.

    A stress test is a test designed to increase the number of simultaneous requests on a system past a point where performance is degraded, possibly even to the point of complete failure. Where a load test will peak out in the number of simultaneous users, a basic stress test will continue to increase load on the system until the resources are overloaded. This pushes the system to a state of potential failure to see how the system handles it and whether the system can perform a graceful recovery.

    Within these definitions of a load test and a stress test, we find that they are certainly not completely independent from one another. Often times, when running the upper boundaries of a load test, you may effectively end up running a stress test where you push the system past the limits of available resources. At this point you might start to see failures in a load test identical to the failures typically seen when running a stress test.

    Difference between Load testing and stress testing?
    Load testing is the testing performance of the software with different users and trying to identify the maximum users supported by the software.
    Example- during Black Friday sales there will be a large numbers users doing online shopping. We can take Macy’s for example. While doing so the Macy’s website will slow down due to load of users.
    Stress Testing is the testing of the performance of software with different resources and trying to identify the optimum resources supported by the software. We need to have optimum resources neither less nor more for the software to work efficiently.
    Example- resources like servers, network devices, hardware components.- how many do we require?

  13. What are the Load Testing goals?

    -Determines maximum functioning capacity of an application when multiple users hits simultaneously.
    -Determines the sustainability of the app for different users.
    -Determines whether the present infrastructure is sufficient to run the application.

    What are the difference between load testing and stress testing?
    Load testing & Stress testing are types of Performance testing.Load testing means putting different amount of load(users)
    on the system and waiting for its response.That means here we measure the system performance based on the different amount
    of users.While in Stress Testing we measure the break point of the system.It specifies how the system works under extreme
    conditions.Stress Testing is also known as Endurance Testing.The main use of this testing is to set the limit when
    ever the s/w or h/w crashes.

  14. Load testing goals are:
    To check the performance of the system under varying loads, in terms of
    1. Server response time
    2.Time taken for each transaction
    3.System components
    4.Design flow
    5.Database response

  15. 2. Load testing is done to check for the performance of the system with varying load of users whereas stress testing is done to check for the performance of the system with varying resources.

  16. -Response time for each and every transaction
    -Performance of the system components under different loads
    -Performance of database components and their behaviour with different volumes of data
    -The network delay between client and server
    -Software application design issues affecting the performance
    -Server configuration like web server, application server issues
    The load testing specifies whether the software needs a fine tuning or modified for hardware and software to improve the performance.

    -While testing the app with more than maximum number of user and input is defined as stress testing. ->In Load testing we measure the system performance based on a volume of users. While in Stress testing we measure the breakpoint of a system. Some parameters to check State of servers/application.
