In software testing, test automation is the process of controlling the execution of tests. It helps in implementing faster test cycles by making use of automated tools. Automated testing is used in functional regression testing, performance testing, load testing, network testing and security testing. Test automation tools can be expensive so they are usually employed in combination with manual testing. If used repeatedly in regression testing, automation testing can be made cost effective.
There are different stages of automation that need to be followed when conducting the testing process:
Test Automation Assessment and Feasibility Analysis –the very first step in test automation is to check if an application can be tested automatically or not.
Appropriate Tool Selection - The Next most important step is the selection of tools. Which tool is suitable for testing the application?
Evaluate the suitable framework - Upon selecting the tool the next activity is to select a suitable framework. This is the most critical phase as the entire framework of the system is implemented and the script is prepared to execute it.
Develop Automation Framework – After the selection of the framework, it should be built after meticulous analysis of the technology and its key features.
Execute, Analyze and Report - Test, result and review are the main components of the execution phase. In the last phase the defects are identified and are then reported for testing.
Benefits can be driven out of the following tests that are
1) Subject to human error
2) Run for multiple builds
3) Require multiple data sets
4) Impossible to perform manually
5) Run on several different hardware or software platforms
6) Time consuming
Automation test planning
The best way to go about automation testing services is to plan and design work carefully. As mentioned earlier the first step is to identify what tests need to be automated. Different tests have different functions such as Unit testing is used to test a small part of the application whereas Load testing is performed to know the working of an application under a certain load.
Structuring also plays an important role in automation testing. It is best to divide and categorize the tests into different levels to make the process more coherent and manageable. Testing early and testing more often can also be beneficial. The earlier the testers get involved in the development cycle there is more possibility to find bugs. It is also proven to be cheaper to fix bugs early than at the later stage.
Automated testing, in which different tools are used for testing helps the team improve software quality and make the most out of their limited resources. Automation testing helps the team in testing faster, accurately and efficiently. It saves up on their time well as they can focus on other tests that require manual attention.
