Based on Wikipedia definition Velocity is " ...the rate of change of its position with respect to a frame of reference and is a function of time...", which when transferred to the scrum world can be summarized as: The amount of work that the scrum team completed in a single measure of time - in a sprint. How we Calculate Velocity? Velocity is actually a very simple to calculate, it is done but totaling the number of story points of fully completed user stories from the sprint backlog. So if a current sprint included 4 user stories: 2 with 8 story points each, one with 3 story points and one with 32 story points. and by the end of the sprint the 32 one was not fully done the velocity calculation will be: 8+8+3=19 Note: the 32 story points are not part of the velocity calculation as this user story was not completed. What Velocity is used for? The v...

Today I want to discuss a popular topic regarding a difference between Load and Performance testing. Those two types of testing are commonly used together but there are several key differences between the two. To get a better understanding of the topic lets have a real life example from one of my clients and use it to explain the difference. I have worked for a client that was building an in-house web application that provides its customers with an option to select and order different products and services. The request was, before the up-coming release, to test the performance of their product.

The client said that they are looking to have about 900-1300 active users on the site at a given moment, and the expected response time (for a page to load) should be less than 5 seconds. With those details what are the t...
