Parameterization and Correlation (Load Runner, Jmeter and VSTS)
Welcome to Performance Testing Gyaan😀 In this post I will discuss about Parameterization and Correlation. The terms are used during scripting of performance test cases. Parameterization : You will often be required to provide different values for the user input for each Vuser during load testing. These values (for example a username and password) can come from different data sources like a csv file, xml file, or from a database etc. This technique of replacing hard-coded values of user input with variables or parameters is called Parameterization. Correlation : This is similar to parameterization except that the same concept is applied to parameterize values that are dynamically returned by the server, in its response to a request from the client. Examples are session id, security tokens etc. These dynamic values are often required by the server to distinguish between the multiple users. Load testing tools will provide different functions or ways in which parameterization and co...
