Acceptance testing is a testing that is performed from user point of view to confirm whether software system has met the requirement specifications or not. The main motive to perform acceptance testing is to evaluate the system’s compliance with the business requirements in order to ensure whether it is acceptable for delivery or not.
Acceptance Testing is performed after the System Testing and before making the system available for actual use. Acceptance criteria are defined on the basis of different attributes like Functional Correctness and Completeness, Data Integrity, Usability, Performance, Timeliness, Confidentiality and Availability, and many more.
Alpha testing is one of the Acceptance testing that is mostly used in software development. It is performed in order to identify all the possible issues or bugs before launching the product live.
The main aim is to carry out the tasks that a typical user might perform. This testing takes place at the developer’s site.
In one phase of Alpha testing, software is tested by in-house developers wherein they use either debugger software, or hardware-assisted debuggers to identify the bugs. In the second phase of Alpha testing, the software is handed over to the QA team, for additional testing in an environment that is quite similar to the user.
Automation testing is a technique where tester writes the test scripts and uses appropriate tools to write and execute test cases, no manual involvement is required while executing an automated test suite. It is basically an automation process of a manual process. The main goal of Automation testing is to increase the test efficiency and develop a quality software.
It uses an application to implement entire software life cycle in less time and provides efficiency and effectiveness to the testing software.
Similar to regression testing, Automation testing also used to test the application from load, performance and stress point of view.
Beta Testing is also known as Field testing as it takes place at customer’s site. System/software is send to users who install it and use it under real-world conditions.
The main aim of beta testing is to place an application in the hands of real users outside of engineering team to discover flaws or issues from the user’s perspective that we would not want to have in final, released version of the application.
Beta testing helps in improving the quality software development by allowing the “real” customer to provide inputs into the design, functionality, and usability of a product.
Blackbox Testing is an input/output driven testing technique in which software is viewed as black-box with inputs and outputs. In this testing, we are not interested to know the internal structure of the product or how it is working, we are just interested in getting the correct output as mention in the specification. The tester is concentrating on what the software does, not on how it does it. It is also known as behavioral testing or specification based testing.
Tests are done from a user’s point of view and will help in exposing discrepancies in the specifications.
Black-box technique are of different types like Equivalence partitioning, Boundary value analysis, Decision tables and State transition testing.
Database testing is the type of testing that basically deals with the testable items that are generally hidden from the user. Database testing should be distinguished from strategies to deal with other problems such as database crashes, broken insertions, deletions or updates. This will improve the quality of the database or web-based system.
Database testing involve checking of the data mapping, integrity of data, ACID (Atomicity, Consistency, Isolation, Durability) properties validation Ensure and Accuracy of the implemented Business Rules. This includes different process and storage like Assembly, DBMS like Oracle, SQL Server, MYSQL, etc.
End-to-end testing is a technique used to test whether the flow of an application right from start to finish is behaving as expected. The purpose of performing end-to-end testing is to identify system dependencies and to ensure that the data integrity is maintained between various system components and systems.
The entire application is tested for critical functionalities such as communicating with the other systems, interfaces, database, network, and other applications.
Exploratory testing provides freedom of testing to any well skilled tester to test and to continuously optimize the quality of his/her work by treating test-related learning, test design, test execution, and test result interpretation. The test design and test execution activities are performed in parallel typically without formally documenting the test conditions, test cases or test scripts.
It is a hands-on approach in which testers are involved in minimum planning and maximum test execution. In this, the tester keeps on making the decisions about what to test next and where to spend the (limited) time. Testers understand the application first by exploring the application and on that understanding basis they should come up with the test scenarios. After that they start the actual testing of application.
This type of testing validates a system’s ability to be able to allocate extra resource and to move operations to back-up systems. This type of testing is used to verify an IT system’s ability to continue operations while the processing capability is being transferred to a back-up system. This type of testing determines whether a system is able to allocate extra resource such as additional CPU or servers during critical failures or at the point the system reaches a predetermined performance threshold.
After unit testing is completed, developer performs integration testing. It is the process of verifying the interfaces and interaction between modules. While integrating, there are lots of techniques used by developers and one of them is the incremental approach.
In Incremental integration testing, the developers integrate the modules one by one using stubs or drivers to uncover the defects. This approach is known as incremental integration testing. To the contrary, big bang is one other integration testing technique, where all the modules are integrated in one shot.
Integration testing is the software testing in which individual modules of the software are logically integrated and then tested as a group. The purpose of this level of testing is to expose faults in the interaction between integrated units. Test drivers and test stubs are used to assist in Integration Testing.
It emphasizes on checking the communication among these different modules. Integration Testing is performed after the Unit Testing and before the System Testing. It follows two approach known as ‘Top Down’ approach and ‘Bottom Up’ approach.
Negative Testing is a variant of testing that can be performed on the system by providing invalid data as input. It checks whether an application behaves as expected with the negative input. This is to test the application that does not do anything that it is not supposed to do so.
For the example above Negative testing can be performed by testing by entering alphabets characters from A to Z or from a to z. Either system text box should not accept the values or else it should throw an error message for these invalid data inputs.
Positive testing is the type of testing that can be performed on the system by providing the valid data as input. It checks whether an application behaves as expected with the positive input. . This is to test to check the application that does what it is supposed to do so.
For example – Positive Vs Negative testing
There is a text box in an application which can accept only numbers. Entering values up to 99999 will be acceptable by the system and any other values apart from this should not be acceptable. To do positive testing, set the valid input values from 0 to 99999 and check whether the system is accepting the values.
Regression Testing is a type of software testing that is performed to confirm that a recent program or code change has not adversely affected the existing features. It is part of the verification process and helps to know that changes or defect fixing has not created any unwanted issues.
It ensures that old code still works once the new code changes are done. Regression testing is useful when there are changes in the requirements and code is modified according to the requirement. It can be performed on new builds as well when there are important changes in the original functionality that too even in a single bug fix.
Sanity testing is the subset of regression testing and it is performed when we do not have enough time for doing testing. Sanity testing is the surface level testing where QA engineer verifies that all the menus, functions, commands available in the product and project are working fine.
After receiving a Software build with the minor issues fixes in code or functionality, Sanity testing is carry out to check whether the bugs reported in previous build are fixed & there is regression introduced due to these fixes i.e. not breaking any previously working functionality. The main aim of Sanity testing to check the planned functionality is working as expected. Instead of doing whole regression testing the Sanity testing is perform.
System Testing is performed as the first level of testing where the System is tested as a whole. It checks the behavior of a complete and fully integrated software product based on the software requirements specification (SRS) document. It involves the testing of the functionalities of the entire system from an end-to- end perspective. System is tested in an environment that resembles the production environment where the application/software will be lastly deployed.
System Testing is performed after Integration Testing and before Acceptance Testing by the independent testers. It enables you to test, validate and verify both the Application Architecture and Business requirements.
Unit testing involves only those characteristics that are vital to the performance of the unit under test. This encourages developers to modify the source code without immediate concerns about how such changes might affect the functioning of other units or the program as a whole. Once all of the units in a program have been found to be working in the most efficient and error-free manner possible, larger components of the program can be evaluated by means of integration testing.
White-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of testing software that tests internal structures or workings of an application, as opposed to its functionality. It is a method of testing software that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing). In white-box testing an internal perspective of the system, as well as programming skills, are used to design test cases. The tester chooses inputs to exercise paths through the code and determine the appropriate outputs.
