Application Testing is such an activity that is performed frequently by almost every software tester in his career. Quality assurance and Quality control these two words are extremely broad in practical aspects. However, only the core and most important areas will be discussed here. The purpose of this article is to touch all the primary areas so that the readers will get all the basic briefings in a single place. Among the numerous professional different types of software testing procedures used by Quality Assurance software testing companies
What are the Different Types of Software Testing Methodologies?
Basically, the Different types of software testing are divided into two parts functional and non-functional testing, Here our team also focuses on some major software testing types While delivering software quality assurance testing services, let’s Explore…
It is the most common type of QA testing that is used by independent software testing companies. The objective of this testing is to identify all possible issues or defects before releasing it into the market or to the user. Alpha testing is carried out at the end of the software development phase but before the Beta Testing.
An acceptance test is performed by the client and verifies whether the end-to-end flow of the system is as per the business requirements or not and if it is as per the needs of the end-user. The client accepts the software only when all the features and functionalities work as expected. It is the last phase of the testing, after which the software goes into production. This is also called User Acceptance Testing (UAT).
The name itself suggests that this testing Service is performed on an ad-hoc basis i.e. with no reference to the test case and also without any plan or documentation in place for such type of testing Service. The objective of this testing Service is to find the defects and break the application by executing any flow of the application or any random functionality. Ad-hoc testing is an informal way of finding defects and can be performed by anyone in the project. It is difficult to identify defects without a test case but sometimes it is possible that defects found during ad-hoc testing might not have been identified using existing test cases.
The aim of the accessibility testing Service is to determine whether the software or application is accessible for disabled people or not. Her disability means deaf, color blind, mentally disabled, blind, old age, and other disabled groups. Various checks are performed such as font size for the visually disabled, color and contrast for color blindness, etc.
Whenever an input or data is entered on the front-end application, it stores in the database, and the testing Service of such a database is known as the Database Testing Service or Backend testing Service. There are different databases like SQL Server, MySQL, and Oracle, etc. Database testing Service involves testing table structure, schema, stored procedure, data structure, and so on.
Browser Compatibility Testing
It is a subtype of Compatibility Testing Service (which is explained below) and is performed by the testing team. Browser Compatibility Testing Service is performed for web applications and it ensures that the software can run with a combination of different browsers and operating systems. This type of testing Service also validates whether web application runs on all versions of all browsers or not.
Dark Box Testing
Internal system design is not considered in this type of testing Service. Tests are based on the requirements and functionality. Detailed information about the advantages, disadvantages, and types of Black box testing Services can be seen here.
Edge Value Testing
This type of testing Service checks the behavior of the application at the boundary level. A boundary value Testing Service is performed for checking if defects exist at boundary values. Boundary value testing Service is used for testing a different range of numbers. There is an upper and lower boundary for each range and testing is performed on these boundary values.
It is a type of software testing service in which it validates how software behaves and runs in a different environment, web servers, hardware, and network environment. Compatibility Testing ensures that software can run on different configuration, different databases, different browsers, and their versions. Compatibility testing service is performed by the testing team.
It is mostly performed by developers after the completion of the unit testing service. Component Testing service involves testing multiple functionalities as a single code and its objective is to identify if any defect exists after connecting those multiple functionalities with each other.
Similar to system testing, End-to-end testing service involves testing a complete application environment in a situation that mimics real-world use, such as interacting with a database, using network communications, or interacting with other hardware, applications, or systems if appropriate.
Exploratory Testing service is informal testing performed by the testing team. The objective of this testing service is to explore the application and look for defects that exist in the application. Sometimes it may happen that during this testing major defect discovered can even cause a system failure. During exploratory testing, it is advisable to keep a track of what flow you have tested and what activity you did before the start of the specific flow.
Incremental Integration Testing
Incremental Integration Testing service is a Bottom-up approach for testing i.e. continuous testing of an application when new functionality is added. Application functionality and modules should be independent enough to test separately. This is done by programmers or by testers.
Testing service of all integrated modules to verify the combined functionality after integration is termed an Integration Testing service. Modules are typically code modules, individual applications, client and server applications on a network, etc. This type of testing service is especially relevant to client/server and distributed systems.
It is a type of testing service for which every organization has a separate team which is usually called a Non-Functional Test (NFT) team or Performance team. Non-functional testing service involves testing of non-functional requirements such as Load Testing, Stress Testing, Security, Volume, Recovery Testing, etc. The objective of NFT testing is to ensure whether the response time of software or application is quick enough as per the business requirement.
This term is often used interchangeably with ‘stress’ and ‘load’ testing. A performance testing service is done to check whether the system meets the performance requirements. Different performance and load tools are used to do this testing.
Sanity Testing service is done to determine if a new software version is performing well enough to accept as a significant testing effort or not. If an application is crashing for the initial use then the system is not stable enough for further testing. Hence a build or an application is assigned to fix it.
It is a type of testing service performed by a special team of software testers. A system can be penetrated by any hacking way. Security Testing service is done to check how the software or application or website is secure from internal and external threats. This testing service includes how much software is secure from malicious programs, viruses, and how secure and strong the authorization and authentication processes are.
This is another type of manual testing. Under the System Testing technique, the entire system is tested as per the requirements. It is a Black-box type testing service that is based on overall requirement specifications and covers all the combined parts of a system.
The above-mentioned Software Testing Service is just a part of the testing service which is used by any QA consultant However, there is still a list of more than 100+ types of testing services, but all testing service is not used in all types of projects. Also, there are alternative definitions or processes used in different organizations or in software quality assurance companies but the basic concept is the same everywhere. These testing services, processes, and implementation methods keep changing as and when the project, requirements, and scope change.
