In this tutorial we are going to install and experiment with Dynimize using MySQL running the Sysbench OLTP benchmark. We also play around with the Linux perf command, top and vmstat. This tutorial assumes that you have MySQL and the Linux perf tool installed, and that there are no other CPU intensive workloads on the system other than those being tested. In order for the Linux perf tool to report CPU event counts, this tutorial should be completed on either a bare metal Linux server, or if using a virtual machine guest then virtual PMU support must be enabled by the hypervisor.
The initial part of this tutorial is meant to illustrate how to determine if there is potential for Dynimize to speedup a mysql (or any other program) workload, by checking to …[Read more]

This is the second and final part of a tutorial on how to test a Python/Flask web app with Selenium webdriver. We are testing Project Dream Team, an existing CRUD web app. Part One introduced Selenium WebDriver as a web browser automation tool for browser-based tests. By the end of Part One, we had written tests for registration, login, performing CRUD operations on departments and roles, as well as assigning departments and roles to employees.
In Part Two, we will write tests to ensure that protected pages can only be accessed by authorised users. We will also integrate our app with CircleCI, a continuous integration and delivery platform. I have included a demo video showing all the tests running, so be sure to check it out!
