One of the common ways to parametrize your performance scripts is to use a CSV file. The best example of CSV input files usage is a login process. If you want to test your application across different users, you need to provide a list of user credentials. Let’s assume that we have a login request t...

Another way to parametrize your performance scripts is to use database data through JDBC. JDBC is an application programming interface that defines how a client can access a database. First of all, download the JDBC driver to your database (refer to the database vendor). For example, mysql driver c...
