What Are the Different Types of Software Testing and Its Uses?

Software Testing

Introduction

Software Testing….? What is it? Why do we even care? In simple words, with the help of software testing, we test the software and find if there is any error or not or the final product is as per the requirements of our end-users or not. The primary goal of software testing is to exterminate bugs and to elevate various facets of the software like performance, security, and user experience.

As testers, we hear different kinds of machine testing, including Usability Testing, Functional Testing, Automated Software Testing, Agile Testing, etc. You may have heard and experimented on any of them, but not everybody understands all kinds of studies.

In this write-up, we are going to learn about all the most common types of Software Testing.

1) Alpha Testing:

It is the most commonly encountered method of software testing. Alpha Checks are carried out on the website of the developer. This method of research can be done in the in-house simulated user environment.

Use: This test aims to detect any flaws or weaknesses before being published into the market or to the consumer. Near the completion of software production yet before beta tests, alpha testing is carried out. However, as a consequence of such experiments, small improvements to the design can be made.

2) Acceptance Testing:

It is the last testing process, after which the program continues to function; the device acceptability trial is also named (UAT). Only when all functionality and functions are operating as intended, the client approves the program.

Use: The customer performs an Acceptance Test, verifying whether or not the end to end of the device flow applies to the market specifications and whether it is the end user’s needs.

3) Ad-hoc Testing:

The name implies that this research is conducted ad-hoc, i.e., without relation to the test case and a schedule or documentation for certain experiments. Ad-hoc checking is an indirect means by which flaws may be detected and carried out by anyone in the project. Defaults without a test case are challenging to detect, although often flaws discovered through ad-hoc research cannot be detected in established test cases.

Use: The test’s purpose is to recognize the faults and disrupt the program by conducting some application flow or random function. 

4) Accessibility Testing:

The purpose of the accessibility evaluation is to assess if the program or the device is available to persons with disabilities or not. Disability includes here deaf, mute, physically ill, blind, aged, and other groups of disabilities. Different inspections, such as visually impaired font size, color, and color blindness comparison, are carried out.

Use: It is used to check if the software is accessible to persons with disabilities or not.

5) Beta testing:

Beta testing is a formal kind of consumer product testing. It is achieved in the current world before the commodity is launched for real end-users on the market.

Beta Testing is effective if the client accepts the program. Normally, end-users or others conduct this test. It is the last evaluation until a commercial application is published. Typically, a small number of users in a given region have a Beta version of the program or product released. End consumers use the app, then, and share their reviews. Then, before distributing apps worldwide, the software testing company takes the required steps.

Use: Beta checking is conducted to guarantee no significant program or device defects are present, and from the end-user viewpoint, it meets market criteria.  

6) Back-end Testing:

Once the information or data is input on the front-end server, it is processed and evaluated by the client is called Database Testing. Databases such as SQL Server, MySQL, and Oracle, are also open, testing of databases requires testing the chart’s configuration, schema, storage, data structure, etc. Back-end Research does not require an Interface; testers have easy access to the database, and testers can quickly validate data through various queries. 

Use: During this back-end testing, concerns such as data failure, deadlock, data manipulation, etc., can be detected. These issues can be fixed crucially before the device reaches the development area live.

7) Browser Compatibility Testing:

It verifies whether or not the web application works on any browser edition. It is a Compatibility Evaluation subtype done by the test team.

Use: Browser compatibility testing is done with online apps, ensuring that it operates on various browsers.  

8) Backward Compatibility Testing:

This is a form of evaluation that validates whether the software or modified software that has been created recently performs effectively on the older version of the environment.

Use: Backward Compatibility Checking verifies whether the software version of this software fits correctly with an older software version of the file format; it works well with the data tables, data files, and data structures created by an older software version. When all of the programs are modified, it can work in comparison to the previous edition. 

9) Black Box Testing:

In this form of automated software testing, internal device architecture is not used. Requirements and features are the focus of evaluations, detailed details can be provided here about the benefits, drawbacks, and forms of the Black Box examination.

Use: It is used to verify the software from outside factors responsible for system failures. 

10) Boundary value testing:

This evaluation method tests the output at the program’s border level.

Use: For verifying if defects occur at limits, the Boundary Value Testing is carried out. For measuring a different number set, Boundary Value Testing is used. For each spectrum, there is an upper and lower limit, and these border values are checked. In situations where testing includes a reference scale of 1 to 500, boundary value checks are done for 0, 1, 2, 499, 500, and 501 values.

11) Branch Testing:

Method of testing in a white box and conducted during unit testing. Checking the Branch, the name itself means that the code is carefully checked across each Branch.

Use: This testing method ensures each branch from the decision point is implemented at least once and thereby confirming that all reachable code is implemented and working properly.

12) Comparison Testing:

Comparison Testing is compared between the intensity and limitations of a product with its existing iterations or related items. It uses the intensity and limitations of a product with its existing iterations or related items.

Use: It is used to provide crucial information to the business to uncover the application’s competitive strong points in the market concerning loopholes.

13) Compatibility Testing:

Checking for consistency means the software works on a particular setup, multiple libraries, browsers, and variants. The research staff performs compatibility checks. 

Use: It is used to check and verify if the software functions or operates well with different operating systems, browsers, mobile devices, databases, hardware, and networks or not.  

14) Component Testing:

Primarily carried out after unit testing by developers. Component testing includes multiple functionality testing as a single code.

Use: It is used to determine if there is a defect following the linkage of these multiple functionalities.

15) End-to-end testing:

End-to-end testing involves testing the whole application environment in a situation that reflects real-world applications.

Use: It is used in applications such as interacting with a database, communicating via a network, or, where appropriate, interacting with other hardware, applications, or systems.

Conclusion: 

This writeup inscribed a few most common software testing types from a huge ocean of types that are most commonly included in the life cycle of testing by different Independent software testing services companies.

Alternative definitions or methods are often found in numerous entities, but everywhere the underlying principle remains the same. The styles, procedures, and execution methods of these tests begin to evolve as the project, requires, and scope evolves.
