Different Testing Levels supported by Selenium

Selenium types of examine cover multiple levels — from fume and sanity checks to UI, database, regression, and cross-browser validation. By supporting these varied test levels, Selenium ensures web apps stay functional, compatible, and reliable across environments.

This article explains the differenttypes of testing supported by Selenium, their welfare, and how parallel performance enhances test speeding and reportage.

Levels of Testing in Software Testing

There are different levels during the prove procedure. Each of these screen stage has a specific intent that adds value to the.

Main Testing Levels in an SDLC include:

• Unit Testing

is a type of software testing that validates every little portion of the software by isolating it in small ‘ units ’. Each unit is tested for its functional correctness. This is performed during the application development level and is usually performed by the developers.

• Integration Testing

It is a type of software examine where the interface between two software unit or modules is test. The main focus is to shape the rightness of the interface. This is execute after the Unit testing and is done by the testers.

• System Testing

It is a type of software testing that validates the complete and fully integrated software merchandise from an perspective. It uses Black Box testing techniques to evaluate the accomplished scheme ’ s compliance against specified requirements. This is performed by a testing squad independent of the development team.

• Acceptance Testing

is a type of software testing where a system is test for Acceptability. It is formal testing establish on the requirement of the user and function processing. It influence whether the software developed is as per the original requirements or not.

Once all the above testing is completed and the software works as expected, it is render to production.

What is Selenium?

Selenium is a costless open source tool that is used for automate tests for Web applications that are pack out on different web browsers and platforms. Selenium consists of a Suite of Software, each catering to different examine needs of an arrangement.

Some reasons for the turn popularity of Selenium are as follow:

1. Since it is an open-source puppet, no licensing cost is involved.
2. Multiple programme languages such as C #, Java, Python, Ruby, PHP, Perl, .Net, etc can be used to create Selenium Test Scripts.
3. Tests can be carried out in multiple operating systems such as mac, Windows, or Linux
4. Tests can be carried out in multiple browser such as Mozilla Firefox, Google Chrome, Safari, Opera, etc.
5. For managing examination cases and generating reports, it can be incorporate with different instrument such as and.
6. For accomplish uninterrupted testing, it can be mix with Jenkins, Maven, and.
7. Selenium supports parallel execution.
8. Selenium endorse test methodologies.

Different Testing Levels supported by Selenium

Pro tip: Tools like SUSA can handle this autonomously — upload your app and get results without writing a single test script.

Selenium supportsFunctional Testing. As per Selenium ’ s official site, “ it supportsFunctional Testing at the System Testing Level and the Acceptance Testing Levelof the Software Development Life Cycle ”. Selenium automatize the functional tests at the UI layer of the Web application under test.

Functional Testing with Selenium

is a type of package testing where a system or a package application is screen against the product ’ s business necessity. It drive to test each functionality or characteristic of the software application by give sufficient input and examining the output against the functional requirements. Thus, it answers the question & # 8211;“ Are we building the merchandise flop? ”

Since functional testing expend Black Box techniques, the functionality of the system can be tested without knowing the home workings of the software.

Functional testing comprises of the below step

• Identify examination input
• Compute test outcome
• Execute Test
• Compare test outcome with require outcome

Following Functional testing types can be automate using Selenium:

Smoke Testing

is one of the democratic software testing performed after Software Build to find if the major or critical functionalities of the program or the scheme are working amercement. It ’ s fulfill on the Initial Build before any elaborate functional tests are executed on the program which regulate whether the build is stable plenty to carry out farther tests.

For model, for a Gmail application, the important functionalities would be Login, Compose Mail and Send. If there is an error in mail a post, then rather of ascertain the features in the grapevine, the Build is rejected. This saves time for the QA team.

Sanity Testing

Sanity Testing is a special case of package testing that is perform on a stable software progress with little changes in codification or functionality to ascertain that the codification changes are act correctly and no further issues are introduced due to these changes. The independent objective is to control the correctness of the application, in light of the changes get. Random tests and stimulus are execute to check the functioning of the software primarily on the changes get.

If the Sanity test fails, the Build is rejected by the QA squad. Early catching of defects saves clip and money during product development.

UI Testing

or GUI testing is a case of screen where the Graphical User Interface of the application is tested to verify if it meets the expected functionality and performance. The primary target is to check that the UI functionality works as designed. It include testing all ocular and graphical icons like card, checkboxes, radio push, case, colors, etc.

The main aspects of UI screen include

• Compliance
• Functionality
• Performance
• Usability
• Ocular Design

Database Testing

is a type of testing that verifies whether the data updated and displayed on the application UI is in sync with the data store in the application ’ s database. The main objective is to validate database eubstance and information unity by create difficult inquiry to load and punctuate the database and survey its responsiveness. It is a layered procedure that include the UI layer, Business layer, Data access stratum, and the database itself.

Cross Browser Testing

is a type of testing to control if an application act as expected across different web browsers. The chief objective is to control the compatibility of the covering with the different browsers. This helps in enhancing efficiency and user experience.

Regression Testing

is a type of testing that deals with testing a previously tested package or application to ensure that the existing features were not affected by a recent program or codification modification or new defects were not introduced by these code changes. It is a full or partial pick of already executed test causa that are re-executed to assure the existing functionalities act o.k..

Steps for Regression testing involve-

1. Re-testing
2. Regression examination selection

This ensures a stable product with new features free faster in the grocery. This besides helps in cost saving which can benefit an organization.

Parallel Testing in Selenium

enables running identical tests simultaneously in different environments. This assist in reducing the overall clip and effort of browser testing.

Why run test in Parallel?

• Executing is a fast approach than successive examination. Testers are provided with wider examination compatibility in less span.
• It cut test time by running tryout on multiple machines in parallel.
• Since parallel testing runs on the cloud, there is no want for maintenance.
• You can buy more time and work on detailed reports of test data.
• You can leverage the cloud and virtualization to perform more tests at a fast speed.

Selenium consists of a set of tools that help the testing operation. Following are the four components:

Out of the four,Selenium Gridis the component that supports Parallel testing. It grant parallel testing against diverse web browsers and operating system combination through a Client-Server model. The server is known as the “ Hub ”. It interact with multiple customer.

Hence, the server can be relate to multiple client machines which can then be used to run a browser mechanization script over multiple browsers and operating scheme combinations, simultaneously. Using, you can use Selenium to test hundreds of browsers in analogue, thus salve time and effort.

Conclusion

Selenium indorse a variety of essay levels and helps in automating them. It is one of the most widely-used and democratic tool apply by several test team. Since it supports all the testing levels mentioned above, it is always preferred over other automation puppet.

Selenium is ideal for companies developing application that support heavy traffic, peculiarly e-commerce websites and social media program. The continuous improvement of Selenium over the years has added value to the web development environment.

Hence using Selenium is most probable recommended as a exam mechanisation tool. However, to get more exact exam results it is suggested to run Selenium Tests on. BrowserStack ’ s yield access to 3000+ browser device combinations allowing the QAs to test under for better performance.
