The intrinsic potential to test all elements of the application from the backend to the frontend from a customer viewpoint is a significant benefit of the Selenium tests. Selenium testing, though, can be costly to do. To what degree the testing depends on the browser, but the behavior of browsers has been so varied traditionally that the intention to cross-test different browsers has always been defined.

Selenium helps you to execute multiple browser commands on multiple operating systems, but listing all possible browsers, their separate implementations and the several systems on which they are operating easily becomes an insignificant endeavor.

Here are some testing types supported by Selenium:

1. Acceptance testing: This method of testing is performed to decide whether a feature or device fits consumer needs and standards. In general, this form of research requires the assistance or input of the client, and is a validation activity that addresses the questions such as, "Is the right product being built?”

Automation of this test can be achieved with Selenium for web applications by simulating user expectations. For example, in web applications, this simulation can be achieved by recording/playing or in the various supported languages.

2. Functional testing: This form of test is used to determine if a function or device operates correctly without complications. It tracks the system on multiple levels in order to ensure that all situations are covered and the system does as is to be done. It is an operation of verification that answers, “Whether or not we are developing the right product?” 

This includes generally: the tests work flawlessly and in compliance with the criteria.

Automation of this test can be conducted directly with Selenium for web applications by simulating predicted performance. This simulation can be achieved by recording/playing or in the various supported languages.

3. Performance testing: As the name suggests, the test is done to check the performance of the system. There are two types of performance test:

• Load testing: Load checks are performed to see how well the app performs usually for a certain number of linked users at once under various specified loads.
• Stress testing: Stress checks are carried out to check how well the application performs under stress.

Performance checks are conducted by certain written Selenium tests, in which multiple users replicate a certain function and meaningful measurements are contained in the web applications.

4. Regression testing: This test is normally conducted after a modification, repair or addition of a function. Any checks already executed are carried out again to verify that the update has not disabled any of the current functionalities. Depending on the application and implementation team, the re-executed test set can be complete or incomplete and can contain many different forms.

Final words

Apart from these individual test approaches, Selenium testing supports Test drive development (TDD) and Behavior-driven development (BDD) which are iterative methodologies to eliminate the need for individual testing approaches.
