Performance Testing Process Below is a generic performance testing process 1. Identify your testing environment i.Know your physical test environment, production environment and what testing tools are available. ii. Understand details of the hardware, software and network configurations used during testing before you begin the testing process. That will help testers create more efficient tests. It will also help identify possible challenges that testers may encounter during the performance testing procedures. 2. Identify the performance acceptance criteria – i. This includes goals and constraints for throughput, response times and resource allocation. ii. It is also necessary to identify project success

PJAX Related performance improvements To know about PJAX [(Click Here)(Pjax Railscast)][1] Post from Kavita: [How to PJAX][2] Pjax is a great solution when we want to do partial refreshing of page at the same time maintaining the history of user navigation, But it has few issues when the app grows Basically PJAX works like this, Issuing a PJAX request to refresh the section of the page( eg: #conainer). Basically it fires an html ajax. Rails server handles the html request and renders the complete html page. These html template is parsed by the middleware, which removes the

Rails provides three types of caching techniques: page caching action caching fragment caching The rails_guides_on_caching is the best place to know how it works. This article is to demonstrate fragment caching the Rails Way with various data-stores and clearing those cached fragments on ActiveRecord callbacks on CRUD operations. Rails ActiveSupport::Cache::Store is responsible to do all the read and write operations. 1. The setup By default caching is disabled in rails. You will find the following config commented out in production.rb # Use a different cache store in production # config.cache_store = :mem_cache_store You

What is Redis? Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. Why should we use Redis? By default, Rails uses the database to cache internal application data which can be expensive to generate (menu trees, views, filter results, etc), and to keep cached page contents. Since the database also handles many queries for normal page requests, it can create a bottleneck and increase load-times. Redis provides an alternative caching backend for Rails, taking that work off the database, which is vital for scaling to a larger number of logged-in

[better_errors][1] is a Rack middleware that replaces the default standard rails error page with a more useful one. The default Rails error page is also useful, but there is so much output that we don’t usually need and also there is a lot of other things we might need to see. The features of better_errors gem are awesome: Full stack trace Source code inspection for all stack frames (with highlighting) Local and instance variable inspection Live REPL (Read-Eval-Print Loop) on every stack frame In this local and instance variable inspection is so useful. We can immediately

WebDriver Basics and Setup instructions A: What is WebDriver? • WebDriver is a web automation framework that allows us to execute our tests against different browsers, not just Firefox (unlike Selenium IDE). WebDriver supports Firefox, Chrome, IE, Safari and Opera. • WebDriver supports web as well mobile application testing so we can also test mobile applications (IPhone or Android). • WebDriver also enables us to use a programming language to create our test scripts (that is not possible in Selenium IDE). • We can now use conditional operations like if-then-else or switch-case. We can also perform looping like do-while. • Following programming languages are supported

In Agile, writing test cases can be little different as compared to other methodologies. We never get entire complete functionality to test because we build the functionalities in iterations and only part of the functionality is delivered in each Sprint (aka iteration). So now whenever any Story is delivered in any Sprint. First thing a Tester must do is request the Programmer for a short Knowledge-Transition (K.T) session regarding this story. And we should cover the following points during the discussion: 1- What should be tested? 2- What should NOT be tested? 3- Any high risk areas? 4- Take
