Introduction To Software Test Automation

What is Test Automation 

• Test automation is the use of software (under a setting of test preconditions) to execute tests and then determine whether the actual outcomes and the predicted outcomes are the same. 

• For example, Windows Vista offers per-application volume. It is possible to turn down the volume on a game while leaving Windows Media Player playing loud. To do this, right-click on the speaker icon in the lowerright-hand corner of your screen and select "Open Volume Mixer." Moving the slider for an application down should cause its volume to decrease. Testing this manually is easy. Just play a sound, lower the volume, and listen. Now automating this rather than doing it manually is the process of test automation. 

Where does Test Automation fit in the Software Life Cycle 

• Considering the earlier software life cycles such as the waterfall model the test automation appears in this life cycle during the implementation and testing phase.

Why do we need Test Automation 

• Companies not only want to test software adequately, but also as quickly and thoroughly as possible. To accomplish this goal, organizations are turning to automated testing.
• To increase the test coverage 
• Reduces the need for manual testing and discovers defects manual testing cannot expose and also manual testing is error prone and a time consuming process. 
• Running the tests again and again gives us the confidence that the new work we added to the system did not break the code that used to work and also to make sure that the changes we introduced are working.
• Running the tests again and again gives us the confidence that the new work we added to the system did not break the code that used to work and also to make sure that the changes we introduced are working.
• Executing the tests (particularly acceptance tests) can also help us understand what portion of the desired functionality has been implemented. 
• The set of the automated test suite can form a regression test suite. The purpose of the regression suite is to make sure that the software behavior is unchanged unless due to data change or latest software. 
• Automating also reduces the time taken for regression testing. 
• Automated unit test suite helps find the problems at an earlier stage and solve them. 

Test Automation Using Testing Frameworks 

What is a Testing Framework

• A testing framework or more specifically a testing automation framework is an execution environment for automated tests. It is the overall system in which the tests will be automated.

• It is defined as the set of assumptions, concepts, and practices that constitute a work platform or support for automated testing. 
•  The Testing framework is responsible for: 

1. Defining the format in which to express expectations. 
2.  Creating a mechanism to hook into or drive the application under test 
3.  Executing the tests 
4.  Reporting results 

•  Properties of a testing framework:  

1. It is application independent. 
2.  It is easy to expand, maintain and perpetuate. 

Why we need a Testing Framework  

• If we have a group of testers and suppose if each project implements a unique strategy then the time needed for the tester become productive in the new environment will take long. 

• To handle this we cannot make changes to the automation environment for each new application that comes along. For this purpose we use a testing framework that is application independent and has the capability to expand with the requirements of each application. 

• Also an organized test framework helps in avoiding duplication of test cases automated across the application. 

• In short Test frameworks helps teams organize their test suites and in turn help improve the efficiency of testing.
