Why is the Important of Load Testing in Applications

What makes any software a better one and more acceptable one by on the customer front is the fact that all the probable glitches and bugs have been rectified. But, how will you know about the present glitches or problems? Software testing, of course! That’s what makes the testing process a vital part of the software development life cycle. Software testing helps the developers to modify the software to create a better version of the same.

Load testing is a vital part of the whole software testing procedure and is a type of performance testing which deals with the load taking capacity of the software. It is the process by which the performance of the software is checked under normal load as well as peak load.

Load testing is a specific part of performance testing of the software which deals specifically with the load taking capacity of the software under consideration along with checking the performance of the whole as well as the various parts of the software which has been integrated to create the whole, under normal and spiked load conditions. Load testing is usually classified as a non functional testing procedure but can be used to perform functional testing to check how the software functions under various load conditions. The developers can rectify the various problems caused by the load on the specific software which affects the performance of the software on the whole. The best part of load testing is the fact that it accurately depicts the actual real world scenario where the software will be used by real users.

In the current time, people have a lack of time. Everybody is leading a hectic life and hence they need everything fast. This applies in case of software too. People are always on the lookout for a software which will deliver in a fast paced manner even under the condition of spiked load. Software which lags under increased load is often rejected by the customers. This makes load testing an absolute must if the developer is trying to make his software successful. Apart from checking the overall performance of the software, load testing also helps in checking how fast the software springs back to its original self even if it snaps under pressure.

While planning out the load testing for any particular software, the tester has to bear in mind the build up of the software that is being tested as well as the desired effect that it is supposed to produce when being used by the customers, because the improvement of the software will depend solely on these results. The tester also has to bear in mind to make the results as accurate and precise as possible. It is also very important to maintain a log of all the load tests performed throughout the whole development process, so as to get a hang of the repetitive bugs that are occurring o that special attention can be paid to abolish them and prevent them from returning further. The various components of the software also need to be thoroughly checked.

So this is a gist of why load testing is important for any application to make it successful and an absolute favourite among the customers. Load testing needs to be introduced into the development life cycle of the software as early as possible so that the problems can be detected and resolved before they get further complicated by the introduction of newer problems. We hope to have helped you to understand the importance of the process and satisfy all your queries.


Best Practices to Follow While Performing ERP App Performance Testing

Best practices, while performing ERP app performance testing

Unlike normal software, enterprise resource planning (ERP) applications are designed to help businesses to collect data on various business activities, and analyze the data to form an integrated overview of core business processes. So these applications are designed by integrating a variety of software application. Also, each ERP system is customized according to the specific needs of the business. The business has to make and implement custom test plans according to the specific features and functionality of the ERP application. At the same time, the QA professionals need to keep in mind a number of best practices to test the ERP application effectively.

Best Practices for Testing ERP Applications Efficiently

Understand Different Testing Approaches

The QA professionals need to perform a variety of tests to assess the performance of an ERP application accurately. They have to perform functional testing to check if the application provides the expected solutions to the business problems. Likewise, they have to perform integration testing to ensure that different components integrated into the system are working flawlessly together as a single application. Also, they need to conduct performance testing to check how the integrated components of the system are performing in specific situations. However, each type of testing must be performed with a particular objective. For instance, performance testing will aim to check how the application performs under specific conditions, without focusing of the defects or flaws in the system.

Gather Detailed Information about the ERP Application

A business can use ERP systems to monitor and manage various processes. So the features, functionality and usage of individual ERP applications differ according to their usage and requirements. To test the software effectively, each member of the QA team must understand key aspects of the project. Before testing the application, each tester must know number of modules to be tested, along with identifying the system users, business requirements, and industry verticals. The project manager can easily provide the key information to testers by making a comprehensive test plan.

Estimate the Testing Efforts

Often testers have to perform all tests required for assessing the performance of the ERP application within a stipulated amount of time. So the project manager must estimate the amount of time and efforts required for performing each type of tests. He need to calculate the amount of time required for writing test cases and test suites, executing all test cases, and preparing test reports. The manager can always refer to the previous testing strategies and test execution plans to estimate the time required to assess the performance of the ERP application comprehensively.

Test Automation

A business can always faster and reliable test results by automating the performance testing efforts. The test automation tools will enable testers to repeat certain tests to assess the performance of the ERP application more accurately. But a business cannot automate all manual testing efforts. So the project manager must decide the business processes testing and test scenarios to be automated. At the same time, he also needs to identify the right tools to make the testers more productive and get better test results. However, he still need to compare the manual and automated test results to assess the performance of the system more effectively.

Define the Process for Test Data Collection and Evaluation

It is also important for the businesses to deploy testers who have prior experience in ERP applications testing. The experience will help them to write test automation scripts by keeping in mind all business requirements and usage scenarios. However, the manager still needs to evaluate the test cases to ensure that all business use case scenarios are covered. At the same time, he also needs to define the process for collection of test data for both input and output. Further, the output data must be evaluated by a domain expert to ensure that the ERP application is performing according to the predefined requirements and specifications.

On the whole, the testers must understand the business requirements and processes clearly to test the ERP application efficiently. The project manager must make a comprehensive test plan to help testers obtain detailed and relevant information instantaneously. They can further refer to the test plan to ensure that all aspects of the application are tested within a shorter amount of time.
