INTRODUCTION TO TEST AUTOMATION

-

Introduction

In the world of Software testing, Test Automation is the use of a external tool that can control the execution of a test case and can compare the actual result with the expected/predicted result. Sometimes, Regression testing of an application becomes time consuming and laborious when it comes to a release and with every release the count of regression test case increases. A manual approach might not always be effective in finding certain classes of defects. To mitigate such issues, we now-a-days offer test automation as a possibility to perform these types of testing effectively. Once automated tests have been developed, they can be run quickly and repeatedly. This can be a cost-effective method for regression testing of software products that have a long maintenance life. Test Automation is applicable to GUI and API. Following are the types of testing that we mainly prefer to Automate:
  • Unit Testing,
  • Performance Testing,
  • Security Testing
  • Functional Testing,
  • Regression Testing,
  • Integration Testing, and
  • Smoke Testing
Initially, there were different tools which used to record and play the test cases, but now-a-days everyone try to script their own code to automate the application with the use of different programming languages that are used by the selected tool.

How to Automate?

These should be followed to get best results of test automation:-
  1. Decide what Test Cases to Automate,
  2. Select the Right Automated Testing Tool,
  3. Divide your Automated Testing Efforts,
  4. Create Good, Quality Test Data, and
  5. Create Automated Tests that are Resistant to Changes in the UI.

Decide What Test Cases to Automate

Before starting test automation, everyone need to know which test cases should we automate? Well, the answer is pretty simple. We mainly automate the test cases which met the below mentioned conditions/criteria's:
  • Repetitive tests that needs to be executed for multiple builds.
  • Tests that tend to cause human error.
  • Frequently used functionality that introduces high risk conditions.
  • Tests which are impossible to perform manually.
  • Tests that run on several different hardware or software platforms and configurations.
  • Tests that take a lot of effort and time when manual testing.

Selecting Automated Testing Tool

There are many test tools available in the market. I am trying to provide some names along with official website links.

Unit Testing
Security Testing
Performance Testing
We will be discussing about Selenium in this blog.

The 'WebDriver' Interface The WebDriver interface is used as a reference to its browser class. Following image is the Hierarchy of WebDriver. SearchContext is a top most interface. The methods in this will be abstract as SearchContext is an interface. WebDriver is also an interface which extends SearchContext. WebDriver has nested interfaces names Window, Navigation, Timeouts etc. These interfaces are used to perform specific operation like back(), forward() etc. RemoteWebDriver is a fully implemented class which implements Webdriver, Javascript Executor and TakesScreenshot. As this class is fully implemented class, which means it defines body for all inherited methods. Then we have browser specific driver classes like ChromeDriver(), EdgeDriver(), FirefoxDriver() etc. To execute the tests with Mozilla Firefox browser we generally write WebDriver driver = new FirefoxDriver(); To execute the tests with  Google Chrome  browser  we generally write WebD...

Setting up Maven in Eclipse editor

Why MAVEN? Maven (which means accumulator of knowledge ) is a build tool used to build and manage any Java-based project. It helps us to manage the daily tasks for Java developers easily. Maven provides simple yet  effective dependency management . It uses an XML file (POM.xml) to describe the project that we are building, the dependencies of the software with regards to third-party modules and parts, the build order, as well as the needed plugins. Maven downloads libraries and plugins from the different repositories and then puts them all in a cache on your local machine (C:\Users\ \.m2). Why Maven is used in Selenium? While working in selenium, we have to manage various dependencies (external JAR files) to execute our project, such as: Selenium-Java JARS, Log4j JARS, Apache POI jars etc. We can use MAVEN to reduce our efforts on managing these dependencies by adding them to POM.xml file. When we restore our OS / try to execute the project in different machine, the...

Why Selenium? There are many functional test tools available as we have already discussed before. We prefer selenium over other testing tools because of the following reasons: It is an open source tool, hence zero cost.  It supports many programming languages (i.e., Java, C#, Ruby, Phython etc.) As many people use Selenium tool today, large number of communities exists for help. Selenium’s Tool Suite It consists of multiple tools as discussed below: Selenium IDE Selenium IDE (Integrated Development Environment) is a Firefox and chrome plugin, with an easy to use interface. It is record and play tools, where user records an action in the web page, store it and play the same tests with new values to it. User can export them as a reusable script in one of many programming languages. Selenium 1 (also known as Selenium RC or Remote Control) Selenium RC was the main Selenium project for a long time, before the WebDriver was brought up in Selenium 2, the newest and...
