![]() ![]() The real challenge lies in designing tests for asynchronous calls. ![]() Designing testsĭesigning test cases for synchronous calls is simple, as testers only need to understand each request/response as it relates to user interaction. It’s related to the Q&A approach where testers merely send a request and wait for the response. Synchronous callsĬompared to asynchronous calls, measuring response times for synchronous calls is much easier and more straightforward. With asynchronous calls, the end user’s actions will determine server interactions, and as such, it can be difficult to measure the time it takes to transport the message to the client, or latency.īecause messages are generated by external events and the server decides when to send messages to all connected clients, it’s in testers’ best interest to measure the time it takes for a client to receive a message after the triggering of an external event. Traditionally, testers would measure the time it takes from when a client sends a request and receives a response. Things can get a bit tricky when it comes to measuring the response times of asynchronous calls. Testers must be aware of the differences between the two in order to properly measure response times and validate the performance of their applications. The server automatically pushes information and updates over a single TCP connection (which remains open), allowing for an ongoing, bi-directional conversation. This traditional request-response communication via WebSockets results in synchronous calls.Īsynchronous calls, on the other hand, do not require a client request to initiate a server response. In addition to facilitating real-time applications, WebSockets are also used by web developers as a way of maintaining a faster, longer connection between client and server, even for traditional request-response purposes. ![]() asynchronous callsįirst, you’ll need to understand the kind of WebSocket communication your application is using: synchronous or asynchronous calls. If you’re utilizing WebSocket technology, performance testing will boil down to simulating the bi-directional nature of your application. Providing a full-duplex communication channel over a single TCP connection, WebSocket is the most efficient protocol for real-time responses over the web. ![]() WebSocket technology creates a persistent connection between the client and server, circumventing the requirement for a client-initiated HTTP request to trigger a server response. A stable, high-performance application is your guarantee of providing your customers with an optimal level of service to build loyalty.Introduced with HTML5, the WebSocket protocol allows for more interaction between a browser and website, facilitating real-time applications and live content. It even allows you to highlight correlations that you might not have thought of. NeoLoad provides you with a set of reports that gives you insight into the weaknesses of your application. You will be able to manage populations of virtual users performing the same or different actions at the same time. These scenarios, such as a mass amount of users at the same time, can be very easily reproduced or anticipated thanks to this solution. NeoLoad is specifically designed for vendors whose applications could suffer from poor performance in a hypothetical scenario. NeoLoad's unique technology makes load and performance testing faster, more efficiently and more frequent.īy using Neoload you will be able to deploy your native web, intranet or mobile applications with complete confidence, regardless of the technologies used, it is even compatible with the most recent ones such as GWT, Silverlight, Flex and Ajax Push. NeoLoad is a load and performance testing software for web and mobile applications to simulate user activity and monitor server performance. ![]()
