Automation Testing is a software testing method to run a set of test cases without executing them manually. After executing a number of sets, we can compare actual test results with expected results. In the Automation method, scripted data is executed by Testing Tools that examine the behavior of software, report outcomes, and compare the results.
There are different types of Automation Tests through which you will typically be running more than one set of tests:-
• Layering test types
• Input-output test
• UI regression test
• Unit test
• Integration test
• Code analysis
Layering Test Types: In this test type, we can run more than one set of test suits. After this, we can start monitoring production release, or at least collecting bug reports. We may add manual or automated regression test cases so that we can find problems before customers identify them.
All test cases of varying scenarios rely on the same piece of code, only the parameters would be different in this. After the test case layer, all test cases will encapsulate like URL, concatenation, response SML/HTML, rich-client GUI, etc.
Input-Output Test: Input-output test is used to transform input data into output data. By providing the new input/output pair, we can attain a new result. The test will even check and verify if the software output matches the sample output for each pair. We can also test Web services with the input-output test that calls the service and checks for expected return values.
UI Regression Test: UI regression testing is performed manually or it can be performed automatically with the use of software programs. With the help of the Selenium tool, we will write a script into a Web application and check the screens that come back. We may need to use this type of test when your programming framework doesn’t support different types of tests, or if you have a lot of static features to regression test. It has the advantage that it can have a graphical UI and be maintained by QA people who are not a part of the core programming team.
Unit Test: Unit testing is a software development and testing approach in which the smallest testable parts of an application, called units that are tested individually and independently.
A unit test is a script that evaluates a specific code object by initializing it, calling methods or functions, and checking the return values. Programmers write these tests and then run locally as part of a test-driven development process.
Integration Test: Integration testing is also a software development and testing approach, in which the user collects the smallest testable parts of an application in one part, called Integration. An integration test is a code level script (i.e., one that doesn’t run the normal UI) that tests a complete process involving multiple objects.
In the integration test, we mainly cover the following points:
• Developing features and writing a test case
• Creating an integration testing environment, scheduling and running the tests
• Reporting the result
Code Analysis: Code Analysis in Automation means to test the computer code, static analysis for Security Testing. Static analysis is the process of reviewing the source code or compiled versions of code to help find security flaws. A tester can leverage static analysis to find and return errors and warnings to the developer to correct it.
This is a Standard Process for Successful automation testing that mandates a Software testing process. A developer needs a system for the development process and testers to need a testing process to successfully use test tools.
Different types of Test automation can easily execute thousands of different complex test cases during every test run providing coverage that is impossible with manual tests.
