Before proceeding with this tutorial, let us first understand some of the key concepts associated with Automation testing of an application.
With the growing need for efficient software products, every software development group need to carry out a series of tests before launching the final product into the market. Test engineers strive to catch the faults or bugs before the software product is released, yet delivered software always has defects. Even with the best manual testing processes, there's always a possibility that the final software product is left with a defect or is unable to meet the end user requirement. Automation testing is the best way to increase the effectiveness, efficiency and coverage of your software testing.
Automation testing uses the specialized tools to automate the execution of manually designed test cases without any human intervention. Automation testing tools can access the test data, controls the execution of tests and compares the actual result against the expected result. Consequently, generating detailed test reports of the system under test.
Automation testing covers both functional and performance test on an application.
Automation Testing tools which are used for functional automation:
Automation Testing tools which are used for non-functional automation:
Automation testing has specific advantages for improving long-term efficiency of any software. The key benefits of test automation are:
If we take a look at the type of software applications prevailing in current market scenario, most of the software applications are written as web-based applications to be run in an internet browser. The testing strategy for web-based applications varies widely among companies and organizations.In an era of highly interactive and responsive software processes where many organizations are using some form of agile methodology, test automation is frequently becoming a requirement for software projects.
The most effective manner to carry out test automation for web application is to adopt a pyramid testing strategy.This pyramid testing strategy includes automation tests at three different levels. Unit testing represents the base and biggest percentage of this test automation pyramid. Next comes, service layer, or API testing. And finally, GUI tests sit at the top. The pyramid looks something like this:
