Record and Play Load Testing in 5 Steps

While Apache JMeter allows you to create a load test from scratch, it also gives you the opportunity to Record and Playback load test scenarios for your web or mobile applications. Recording performance test scenarios are very useful when it comes to web or mobile testing. Websites and mobile applications make many requests varying from initial server to 3rd party application like analytics sites etc. Therefore implementing those requests from scratch may not be the best idea. In those cases, we recommend you to use the Recording module of JMeter. JMeter has a special module for that purpose. It’s called [...]

5 Steps to Create a Realistic Load Test!

Functional testing and non-functional testing of an application are slightly different from each other. In terms of ISTQB, functional testing has structured tests scenarios. But when it comes to non-functional ones, we have performance testing and usability testing where the user’s perspective comes into play. Then we have uncertainty as stated below: QA Engineer walks into a bar. Orders a beer. Orders 0 beers. Orders 999999999 beers. Orders a lizard. Orders -1 beer. Orders a sfdeljknesv. But the First customer comes in and asks where the toilet is? The bar bursts into flames and the customer kills everyone. We all [...]

JMeter Timers

Why Do I Need a Timer in JMeter? User behavior in load tests depends on many factors. Those factors can be “ramp-up time”, “user count on the system in a specific time interval”, etc. and most of them rely on timing. The time between user actions defines the realism of the scenario. That’s why JMeter offers various Timer for you to use in your performance test projects. By default, JMeter executes all samplers one after another. There is no delay between sampler’s execution. This makes our tests non-realistic because no user goes into a page and clicks to a link, [...]

Performance Testing Terminology

Performance testing is the process of determining the speed, responsiveness, and stability of a computer, network, software program or a device under a workload. In order to conduct and analyze a good load test, you need to understand the performance testing terminology including connect time, latency, etc... Let’s elaborate on what they mean. Connect Time Connect time is the time taken to establish a TCP connection between the server and the client. TCP/IP model guarantees delivery of data by its nature by using TCP Handshake. If TCP Handshake is successful, then the client can send further requests. That data send/receive [...]
