The Objective of Load Testing The main objective of using the load testing is to fulfill the following aspects: The load testing is used to perform the maximum quantity of software applications without important performance breakdown. It is used to govern the scalability of the application and allows various users to access it. It is used to identify the total count of users that can access the application simultaneously. The load testing is used to determine whether the latest infrastructure can run the software application or not and determine the sustainability of the application concerning extreme user load.

Why is load testing important? The load testing is essential because of the following factor: It guarantees the system and its consistency and performance. The load testing is necessary if any code changes occur in the application that may affect the application's performance. It is important because it reproduces the real user scenarios. It helps find the system's bottlenecks.

Rules for load testing During the execution of the load testing, a test engineer should follow the below rules: A test engineer tries to evade downloading images on the site. Once the application becomes functionally stable, load testing should be planned.

The reliability of response time concludes the past period should be logged and the same should be compared with several test runs. For each scenario or script number of users should be decided. Load Testing Process The Load testing process will be completed in the following steps: Step1: Test environment setup In the first step, we will set up the test environment to execute the load testing to ensure the testing can be done appropriately.

And the test environment should be set up near to the production environment as likely in terms of network, hardware, software specifications etc. Step2: Load the test scenario or specify the performance criteria In the next step, we will define the performance criteria, which contain the response time, reasonable limits on throughput, and the load test transaction.

And then, we create the load test scenarios, which ensure the success criteria are finalized. In the load testing, transactions are decided for an application and data is set for each transaction. Note: A test scenario is a combination of scripts, and virtual users executed during a testing session. The Scenarios could be of two types, either manual or goal oriented.
