What is Load Testing
Load testing is the process of determining the ability like computer, network and device to maintain the level of effectiveness in the unfavorable conditions. Measuring the qualitative test to check and identify the error frequencies to resist the denial of services.

Analyzing the load test
In the current situation, many companies are working with load test to analyze the products effectively. In order to handle and implement them with our software products, we should understand and analyze what we need and how to go about? Analyzing the test load can be carried through various steps to set the goal for your applications.
Identifying the objectives can be done by defining the key areas to with certain parameters like response time, message delivering through the proper communication channel, utilization of resources like human, device, cost, time and the user needs to run the hardware configuration. Utilization of scenario can be used to identify the multiple paths for the multiple activities. This can be identified with the key resource to perform the goal to reduce the impact mostly used in the business aspect. Identifying the workload is to define the ratio of work in numbers to execute the scenario. The existing applications are logged through IIS log and the new applications are worked based on the market research to identify the prototypes and through data. Calculations are used to distribute the concurrent users to share the work.
Identifying metrics are derived based on performance and real time comparison to recover the bottlenecks of your application. Several types are available network metrics gives you the overall health and efficiency includes routers, switches and gateways. System metrics identify the resources to set the CPU, memory and disk. Platform metrics relates the software and host application. Application metrics counters the custom embedding and application code that monitors the concurrent threads to lock the request number. Service metrics measures the overall latency and the output. Analyze what type of features you are going to include to valid your business to the customers sufficiently. Understand the errors and analyze the weakness lies in that, identify the proper iterative to test and improve the techniques more efficiently.
Designing the load test
The load test can be designed and performed to launch and to control the module. The overview of designing can be designed to perform the module part and the performance part to allow the real conditions with the reliable test results. The prerequisite of designing specifics are based on the scenarios, metrics and workload. Designing the exact script to run the load testing is the significant factor to plan and module the documentation.
Designing the test script can be done with the identified modules by creating the new project to configure the properties that are set and referred for later use. Action groups are set to combine the logical actions that are created for various actions like starting, action and ending. Based on your desired behavior you can set the initialization for the order execution of test. By selecting the project node and the tree, you can select the add group and select the descriptive name for the application and command the web applications to run. Creating the functional module for every groups of your application represents the module test by structuring and designing the testing life cycle to increase the reusability of groups across the test scripts.
Some of the necessary points need to be considered to evaluate the designing by ensuring the documents before designing the apt one. Actual designing modules should hold the supplementary data to perform the actual test. Design the invalid data to perform the alternative course of action, if someone has performed the mistype. Assign as such all the data should be collected and retrieved from the database file. Setup the status update orders to perform the user’s activities to accept the batch process. Pass the scenario to test as such to start and execute the test to enhance the design by collecting the results. By assigning all these testing patterns you will be sure enough to pre-check with all the needed documents. After assigning and developed the resource, never attempt to change the pattern as it is difficult to change, even the one particular design.
Implementing load testing
The next stage and the hard part is the implementation stage. Even though companies design and performed the test scripts, many fails during the implementation stage. This may be due to the ignorance of actual fact and the poor designing strategy pattern for the load testing. The quality analyst knows better than the others whether this particular application goes well with the application areas or not by performing the traditional testing life cycle experiments.
For every project the timelines are fixed and kept ready for the execution, through this the testing scripts are identified to test the level of acceptance. The parallel usage of testing lifecycle used to identify the development along with the scope and date of completion are prefixed.
Products performance is the highlighting issues in the industry. The load testing life cycle is the continuous process where the work never ends. Identifying the issues even at the final stage has to be reviewed until the issues are solved; this brings in the positive impact by optimizing the performance and also receiving the complementary from the customer end.
Identifying and solving all the issues helps us to degrade the bottlenecks and improvise the performance. Performing the critical scenarios will help to eliminate the order process by creating the new cases to solve the problem now and then. Verify all the metrics you enabled with the integration helps to identify the objectives to stimulate the load testing and captured the tools to perform the system wise evaluation to adjust the traffic with the infrastructure performance to perform the scalability and reliability to validate the output to record and reused to cover more features with the affordable time and cost. Recognition and acceptance of successful integration of testing cycle confirms the date of releasing the product for the customer’s usage.
