Nowadays technology is totally controlled by machines, and their behaviour is regulated by the software over-powering it. Software Testing and Quality Assurance are important as these recognise the errors from a system at the commencement itself. This blog on “Types of Software Testing” will furnish you with a brief knowledge about the different types of Software Testing. All types of software testing are done to obtain different objectives when testing a software application.


Types Of Software Testing

Agile Testing

Agile Testing is a type of software testing that includes agile software development method and practices. In an Agile development environment, testing is an essential part of software development and is arranged along with the coding. Agile testing enables incremental and iterative coding and testing.

Automated testing

This is a testing approach that uses testing tools and/or programming to perform the test cases utilising software or custom developed test services. Most of the automated tools granted capture and playback facility. However, there are tools that need writing extensive scripting or programming to automate test cases.

Ad-hoc testing

Ad-hoc software testing is so casual and disorganised and can be implemented by any stakeholder with no reference to any test case or test design records. The person conducting Ad-hoc testing should have a solid knowledge of the domain and workflows of the application to attempt to detect defects and breaks of the software. Ad-hoc testing is designed to detect defects that were not exposed by existing test cases.

API Testing

API testing is a type of testing that is comparable to unit testing. Each of the Software APIs are examined as per API specification. API testing is often done by a testing team unless APIs to be tested and requires large coding. API testing needs learning both API functionality and holding good coding skills.

Accessibility Testing

When doing accessibility testing, the purpose of the testing is to decide if the contents of the website can be readily accessed by disabling people. Multiple checks such as colour and contrast (for colour blind people), the font size for a visually impaired, precise and concise text that is clear to read and follow.

Acceptance Testing

Acceptance testing is a formal type of software testing that is performed by the end user when the characteristics have been delivered by developers. The purpose of this testing is to verify if the software confirms to their business requirements and to the conditions given before. Acceptance tests are usually documented at the beginning of the sprint (in agile) and is a method for testers and developers to work towards a general understanding and shared business domain information.

All Pairs testing

Also recognised as Pair-wise testing, is a black box testing method and a testing method where each input is examined as pairs, which supports to test software works as expected with all viable input combinations.

Equivalence Partitioning

Equivalence partitioning is also identified as Equivalence Class Partitioning is a software testing method and not a type of testing by itself. Equivalence partitioning technique is used in black box and gray box testing varieties. Equivalence partitioning groups test data into Equivalence classes as positive Equivalence classes and negative Equivalence classes, such order guarantees both positive and negative states are tested.

Graphical User Interface (GUI) testing

This type of software testing is intended at testing the software GUI of the software meets the demands as stated in the GUI mock-ups and Detailed designed reports. So GUI testing guarantees GUI elements of the software are as per approved GUI mock-ups, detailed design documents, and functional specifications. Most of the functional test automation tools work on GUI capture and playback abilities. This executes script recording active at the same time raises the effort on script maintenance.

Exploratory Testing

Exploratory testing is an unconventional type of testing carried out to study the software at the same time scanning for errors or application behaviour that is unclear. Exploratory testing is usually performed by testers but can be made by other stakeholders as well for example, end users, Business Analysts, developers, etc. who are interested in learning functions of the software and at the same time watching for errors or behaviour is resembled non-obvious.

Beta Testing

This is a formal type of software testing that is conducted out by end customers before issuing or handing over the software to users. Successful achievement of Beta testing means customer approval of the software.

Browser Compatibility Testing

It is one of the sub-types of testing of compatibility testing conducted by the testing team. Browser compatibility testing is done for web applications with combinations of various browsers and operating systems.

Compatibility testing

Compatibility testing is one of the test types done by the testing team. Compatibility testing checks if the software can be run on separate hardware, bandwidth, operating system, web servers, databases, application servers, emulators, different configuration, processor, hardware peripherals, different browsers and different versions of the browsers and more.

Black Box testing

Black box is that kind of software testing technique where testers are not needed to apprehend the coding or internal structure of the software. Instead, it relies on testing software with many inputs and verifying results against awaited output.

Type of software testing conducted to check that the brand-new version of the software can operate strongly on top of the earlier version of the software and that the new version of the software works as accurate with table structure, data structures and files that were conceived by the previous version of the software.

Boundary Value Testing

Boundary Value Testing is a testing method that is based on the idea of “error aggregates at boundaries”. In this examination technique, testing is done widely to check for errors at boundary conditions. If a field receives value 1 to 100 then testing is done for values 101, 100, 1, 2, 99, and 0.

Dynamic Testing

Testing can be implemented as Static Testing and Dynamic testing, Dynamic testing is a testing method where testing can be performed only by doing code or software are classified as Dynamic Testing. Unit testing, Functional testing, regression testing, performance testing and more.

Bottom-up Integration testing

Bottom-up integration testing is an integration testing method where testing begins with smaller pieces or sub-systems of the software until all the way up comprising the entire software system. This type of testing commences with petite portions of the software and finally scale up in terms of size, complexity, and moreover completeness.

Integration Testing

Integration testing is one of the most popular and significant types of software testing. Once the single units or components are examined by developers as running then testing team will run tests that will check the connectivity among these units or component OR multiple units or components. There are many methods for Integration testing accurately, Top-down integration testing, Bottom-up integration testing and a combination of these two distinguished testing methods as Sand witch testing.

Interface Testing

Interface Testing is required when software gives support for one or more interfaces similar to “Graphical user interface”, “Command Line Interface” or “Application programming interface” to communicate with its users or other software. Interfaces serve as the medium for software to allow input from a user and produce an output to the user. Plan for interface testing depends on the type of the interface being tested like GUI or API or CLI.

Big Bang Integration testing

This is one of the integration testing methods, in Big Bang integration testing all or mostly all of the modules are developed and then linked together.

Branch Testing

Is a white box testing approach for designing test cases to test code for each branching condition. Branch testing method is implemented during unit testing.

Component Testing

This kind of software testing is done by developers. Component testing is performed after finishing unit testing. Component testing comprises testing a combination of units as code collectively as a whole preferably than testing individual functions, methods.

Condition Coverage Testing

Condition coverage testing is a testing technique adopted during unit testing, where developer tests for the whole of the condition statements like if-else, if, case etc.

End-to-end Testing

End to end testing is conducted by the testing team and the focus is to test end to end issues e.g. order creation to item return and checking. End to end testing is normally focused on imitating real-life situations and usage. End to end testing includes testing information flow over applications.

Decision Coverage Testing

It is a testing procedure that is used in Unit testing. The purpose of decision coverage testing is to execute and validate every decision block in the code.

Functional Testing

Functional testing is an approved type of testing method followed by most testers. It focuses on testing software against Use cases, design document, and the requirements document. Functional testing is a black box kind of testing and does not need the inside operation of the software, dissimilar to white box testing.

Fuzz Testing

Fuzz or fuzzing is a software testing that comprises testing with accidental or random inputs. The Software is controlled for failures or error messages that are displayed due to the input errors.

Glass box Testing

Glass box testing is a different name given for White box testing. It is the kind of approach that comprises testing individual statements, functions and more. For instance, Unit testing is one of the Glass box testing techniques.

Happy path testing

This kind of testing is also named as Golden path testing, this focuses on the successful achievement of tests that do not utilise the software for negative or wrong conditions.
