Knowing exactly how much your site, application, system, or API (Application Programming Interface) can handle will help identify and uncover numerous issues, like bugs and database slowdowns, well before any code is committed into your staging environment. In the past, load testing was usually only carried out towards the completion of a development project, but with the renewed focus on the Agile software development process, development teams are shifting their testing left, meaning earlier and more often in the process. What is the breaking point? When will I run out of resources?.How many transactions can we handle over a specific period?.How many simultaneous users can my website, application, or system handle?.How will the number of users affect performance?.Through the information gathered during and after load testing, developers can measure the limits and gain insight into the metrics that can help answer questions such as the following: Load testing simulates real-world scenarios on your sites, applications, and systems. So, as you can see, the importance of ensuring your applications is tested to meet performance demands cannot be overstated. Also indicated in their survey were the effects on customers and visitors, such as a decline in customer confidence, tarnished brand integrity, drop in stock price. If you consider specific industries that depend on high-volume transactions, like financial services or large online retailers, the impact could likely be more significant. Additionally, the average length of downtime was 79 minutes. A recent survey conducted by Veeam, a global leader in the backup and data management space, with over 1,500 IT professionals found that the cost of one hour of downtime for high priority applications was over $84,000. Even a few seconds of downtime can significantly impact a company’s bottom line. Poor performing sites and applications can have a negative impact on conversions, transactions, and most importantly, revenue. And hit Run.The definition load testing generally refers to testing as a subset of the software performance testing process, which typically also includes several other types of tests, such as stress testing, soak testing, spike testing, endurance testing, volume testing, and scalability testing, among other types of testing. Fill it as per your load test requirement. It will ask for Number of iterations and delay between each API call.As seen in the screenshot taken from the link, just hit run.Create a collection of the APIs you need to load test.To me it seems like Let's give it a try and 10 minutes later I was bombarding the software with the Load I wanted to test. It talks about something called a Collection Runner in Postman. Just googled How to Load test using Postman, and came across the following link. Thought of installing Locust and do it the way it should be done, well my task was trivial and to use Locust kind of softwares for such a task is similar to using a Chain saw for cutting a carrot, can be done, but it will be an overkill. Didn't want to waste my time figuring out the issues with it. Tried with the 1st option of using the cURL request, but somehow the cURL request wasn't running in the command prompt of windows machine (well Windows!). Find an alternative in already existing softwares running over the machine.Setup a load testing system and use it for the purpose.Create a cURL request and run it over a loop.Task - To load test a Desktop Software running on Windows Machine with XML APIs.
