![]() ![]() Load testing can also be done on an exploratory basis to validate hypotheses and gain a deeper understanding of your systems. It's best to catch issues and errors in these early stages when the cost of debugging is the lowest. At these early stages of the development lifecycle, you can identify bottlenecks and improve the stability of your application before it is released to production. Load testing can be done as a regular part of your Continuous Integration process. You should definitely do all of that in addition to load testing. There's many ways to optimize and balance the load that hits your servers, validate user inputs, and cache static content. Regular load testing is essential, and a great way to optimize your site or apps for peak shopping days. Your servers might not be able to handle all of these simultaneous requests, and you'll piss off your users and lose out on revenue. A single appearance on the front page of the internet can result in an unintentional distributed denial of service (DDOS) attack. Maybe you know exactly when you'll be featured on Shark Tank, or maybe you're totally unprepared for any kind of viral traffic. If you're still reading, you probably want to be proactive and achieve a higher level of confidence about the stability, reliability, and availability of your platform. Other developers might rely on server logs to find out when their servers are crashing. One unbelievably common approach is to throw your code into production, and be ready to roll it back if it doesn't scale well. Sometimes it can include endurance testing, to determine the system's ability to handle a specified work load for a prolonged period of time. Sometimes load testing is completed along with stress testing, to determine the system's ability to handle a heavier than normal workload. During load testing, you will subject an API to a workload that approaches and possibly exceeds the limits of its specifications. Load testing falls under a broader umbrella of performance testing. Once you establish a process for functional and integration testing, the next step is to look at performance testing to gain a deeper understanding about the stability, reliability, and availability of your platform.įor example, how does your system behave when a large number of users are accessing your servers? How long does it take for a user to receive a response? As more users access your platform, does a response take significantly longer or does a request timeout? Is this effect magnified at certain times of the day or week? On the Postman Engineering blog, we've already learned how to get started with test automation. A Postman Collection with tests to execute load testing.how to interpret the results of load testing.how to configure load testing settings in Postman.Basic testing skills like how to write and run API tests in Postman.Parts of this tutorial were originally published at Don't get TechCrunched: performance testing for your HTTP APIs Prerequisites Whether you're already supporting lots of traffic, gearing up for a seasonal spike, or become a viral success, don't get TechCrunched! Load test your APIs with real-world loads to validate their performance before it's too late. Maybe you're getting ready for a seasonal surge in traffic like Black Friday or Cyber Monday, and don't want to lose out on serious revenue in case a critical process fails.Įven startups can become a victim of their own success, if they receive an unexpected mention on TechCrunch or HackerNews and their sites collapse under the influx of new visitors. The etc method only ensures that no additional attributes exist at the nesting level in which the etc method is invoked.If you're a big company with a platform that regularly supports tons of users, you have to know how incremental traffic impacts the performance of your systems. ![]() However, you should be aware that not including the etc method in your assertion chain does not ensure that additional attributes are not being added to arrays that are nested within your JSON object. The intention behind this behavior is to protect you from unintentionally exposing sensitive information in your JSON responses by forcing you to either explicitly make an assertion against the attribute or explicitly allow additional attributes via the etc method. If the etc method is not used, the test will fail if other attributes that you did not make assertions against exist on the JSON object. This method informs Laravel that there may be other attributes present on the JSON object. In the example above, you may have noticed we invoked the etc method at the end of our assertion chain. ![]()
