What is Acceptance Testing? Types and Examples – W3Softech

Acceptance Testing

Acceptance Testing is the final level of software testing. The main aim of this testing is to determine the working process of the system by satisfying the required specifications and it is acceptable for delivery. It is also known as End-User Testing. It also works under the Black Box Testing Method.

Types of Acceptance Testing

The most important seven types of this testing are

User Acceptance Testing (UAT)

The name itself says that it is from the user point of view. It helps to determine whether the system is working for the user with the given specific requirements. Here, the user refers to whom the system is going to handle after completion of all the testing levels. Usually, customers or customer’s customers will perform this testing.

Business Acceptance Testing (BAT)

It helps to check whether the system satisfies the business requirements and specifications. The main aim of this testing is to help in increasing business profits by considering market strategies and technologies.

Contract Acceptance Testing (CAT)

The name itself says that it helps to test the product with all acceptance test cases within the contract period of time. The contract may be like payment will be done before the product goes live or after the product goes live.

Regulation Acceptance Testing (RAT)

If testing undergoes all the rules and regulations that are released by the government then it is said to be RAT. Not even a single violation has not to be found while performing this testing if any occurs then the whole product will be going under failure. So, it is the most important and complicated testing type.

Operational Acceptance Testing (OAT)

This testing mainly used to determine the product’s compatibility, reliability, stability, etc., before it is going to live.

Alpha Testing

Specialized Testers will perform this testing to check any bugs have occurred. Also, they help to give suggestions to improve product usability in a controlled manner.

Beta Testing

Beta Testing helps to grab the bugs or any issues of a product. End-Users will perform this testing with an uncontrolled manner.

Best Example to understand this testing

• During the process of manufacturing a mobile phone, there are so many parts like a camera, speakers, flashlight, buttons, display, headset, charger, etc., will be produced separately by different manufacturers.
• All these parts will first go under unit testing
• After unit testing, they go for integration testing.
• Later, system testing will be performed
• Finally, acceptance testing will be performed before it is out for delivery.

What is Unit Testing? Unit Testing Tools and Types | W3Softech

Unit Testing

The process of testing the individual units of software is called Unit Testing. It will be done during the development of a software application. According to the programming procedure, a unit may be an individual function of the software.

Unit Testing is one of the levels of software testing and usually done by the developer. It is the first level of testing. Developers or QA Engineers will handle this testing.

Working Process of Unit Testing

• With the help of this testing, we can fix bugs or errors during the development cycle
• It enables developers to make changes quickly and saves cost
• It helps to get a good quality software product

Unit Testing Types

It is of two types namely Manual or Automated.

Most probably performed by manually but developers always prefer to do automation testing. It is a white box testing technique comes under following test coverage techniques

• Branch Coverage
• Condition Coverage
• Decision Coverage
• Statement Coverage

Using White box testing methods

• Test cases can be derived that all independent paths within a module have been exercised at least once.
• Exercise all logical decisions on their true and false sides.
• Executes all loops at their boundaries.
• Exercise internal data structures to assure their validity.

Unit Testing Tools

• JTest
• JUnit
• NUnit
• JMockit
• EMMA
• PHPUnit
• xUnit.net
• TestNG
• QuiltHTTP
• HTMLUnit
• EmbUnit
• SimpleTest
• ABAPUnit
• TypeMock
• LRDA
• Cantata
• Karma
• Jasmine
• Mocha
• Parasoft

Advantages

• Developers will be able to understand the functionality of the Unit API
• It helps the developers to rewrite and modify the code anytime and ensure the unit works as usual
• It helps to test each and every unit of the software application so that named as Unit Testing

Disadvantages

• It is very complicated to test each and every unit in large scale programs as it takes a lot of time
• There may be a chance of missing units or paths of code in trivial programs
• It allows testing only certain units or paths of code so that we are unable to grab the integration errors

What is Manual Testing? Types, Tools and Concept | W3Softech

Manual Testing is a type of software testing usually done by testers manually to perform test cases and find out the bugs or errors in a software system. Any software application before going under automation testing must be tested manually.

The major role of this testing is to ensure that the system is defect-free and working properly then let it go for the next step in the development life cycle. Name itself says that this testing is done by manually without using any automation tools.

Working Process of Manual Testing:

• The initial step is to study and analyze completely the project give
• To execute the test cases based upon the business requirements
• Perform testing manually to find out any bugs or defects in the software application and fix them
• Perform retesting by testers to find out any missing bugs in the system and fix them
• Finally, the project will go for the further step after successful completion of testing

Manual Testing

Advantages of Manual Testing:

• This Testing can be done through either functional or non-functional
• Any kind of software application or system can be tested manually

Disadvantages of Manual Testing:

• It requires human intervention
• It requires highly skilled testers and longtime process
• Based upon the above things it costs high
• The testing process will become repetitive so that may get boring

Manual Testing Types:

Actually, any type of software testing can be executed through manually or automatically but below shows the major types of manual testing.

• Black Box Testing
• White Box Testing
• Unit Testing
• System Testing
• Integration Testing
• Acceptance Testing

Manual Testing Types

Manual Testing Tools:

Different kind of Manual Testing Tools

• Appium (Mobile Testing)
• AutoIT (Language Automation)
• Bugzilla (Defect Tracking & Collaboration)
• FileZilla (FTP Solution)
• Firebug / Firepath (Online Debugging)
• GitHub (Project & Source Code Hosting)
• Jenkins (Continuous Testing)
• JMeter (Load Testing)
• Mantis (Bug-Tracking & Project Management)
• Notepad++ (Source code Editor)
• PhantomJS (Headless Browser)
• Postman (API Testing)
• RazorSQL (Database Query Tool)
• Selenium (Web Application Testing)
• TestLink (Test Management)
• UI Automator (Android Testing Framework)

Levels of Testing | Software Testing Levels | W3Softech

There is a total of four levels of testing available in software testing. Here levels can be defined as the process of each and every component of a system is being tested. These four software testing levels are designed to determine any missing errors or functions of a software application in the development of software testing lifecycle.

The Four Levels of Testing in Software Testing:

1. Unit Testing
2. Integration Testing
3. System Testing
4. Acceptance Testing

Unit Testing:

It is the first level of testing in Software Testing also one of the types of functional testing. A unit of a software system is being tested to check the performance of the system is said to be Unit Testing. The main function of unit testing is to test each unit or component of a software application separately.

However, it is impossible to test each and every unit of a software system as there is a limitation for a number of scenarios.

Integration Testing:

It is one of the levels of testing in software testing also comes under functional testing types. It is quite opposite to the unit testing. Integration Testing is a combination of different units or modules. To make a group and perform testing to check the performance of a system. The main aim of this testing is to recognize the interface between the modules.

Software Testing Levels

System Testing:

It helps to determine the compliance of a software system which also meets the specific requirements and quality standards. System Testing involves load testing, performance testing, reliability testing and security testing. It also comes under functional testing types and black box testing technique.

However, it is impossible to perform testing on the whole system so that it uses some of the automation testing tools.

Acceptance Testing:

It is the final level of testing in software testing which also comes under one of the functional testing types. Acceptance Testing or User Acceptance Testing (UAT) helps to determine whether the software application is ready to deliver. It plays a major role in checking whether the system meets expected business requirements and quality standards and ready to deliver.

Functional Testing Types in Software Testing – W3Softech

Software Testing:

Software Testing is defined as the process of testing the software product to make it defect-free under business requirements and the output results should match with the customer’s expected results. Here in this blog, you can find Functional Testing Types and their usage in software testing.

Functional Testing:

Functional Testing is one of the types of software testing which can be defined as the each and every individual function of a software application needs to be operating with required specification. The major role of Functional Testing is to perform individual functions for a software application with respect to the requirements and specifications. Simply we can say that functions of a system need to be tested by given input and the output results should match with the expected results.

Functional Testing Types and their Usage in Software testing:

Acceptance Testing:

An acceptance testing is used to perform by the client and checks whether the total workflow of the software application is as per the business requirements and satisfies the customer’s expectations. The software application will be accepted by the client only when all the functions of system work as expected.
It is also called as User Acceptance Testing (UAT). As the name itself says it is the last phase of testing later the software goes into production.

Beta Testing:

Beta Testing is used to perform in a real-time environment for actual end users before releasing the product into the market. The major aim of it is to check whether there are any failures in the product or not. It must satisfy the business requirements along with customer’s expectations.
Beta Testing is usually done by the end users before releasing the product into the worldwide market. It is said to be successful only when the customer accepts the software.

Integration Testing:

Integration Testing is one of the types of functional testing. It is used to perform testing on all integrated modules and checks whether they are working fine when integrated as worked as individually. In other words, we can say that it is used to test the interfaces between modules.
In this testing modules are called as code modules, individual applications, server applications, etc.,

Interface Testing:

Interface Testing is also one of the types of functional testing. It is ensured to verify whether the communication between two different software applications is done rightly or not. Mainly it is done in two main segments such as Web server and application server and application server and database server.

The main purpose of it is to ensure that the actual end user should not face any failure while using the software product.

Functional Testing Types

Regression Testing:

Regression Testing means re-testing the software product. After applies the code changes which does not disturb or impact the previous functionality of the product. Usually ensures to verify the functionality of the software product after the modification has been done to the product.

System Testing:

System Testing is defined as testing the whole system including all the modules which are integrated as per the business requirements. It also comes under the black box testing technique. It must be done after integration testing and plays a major role in providing a high-quality product. However, it is difficult to perform testing on the whole system so mainly uses some of the automation testing tools.

Sanity Testing:

Sanity Testing can be defined as if a software application is facing the crashing issues at the initial stage of usage and may not be useful for further testing then there is a need of building an application to fix it. It also comes under one of the functional testing types. It can be done depending on the implementation and its impact.

Smoke Testing:

It is the first phase of testing that should be done on any new build application. Smoke Testing is a type of software testing used to perform a group of tests. It ensures to check whether basic functions of the software application are working correctly as per the business requirements.

Unit Testing:

Unit Testing can be defined as the testing of an individual software module or component. It is quite opposite to the smoke testing. It is usually done by the programmer as the method of writing code to verify the written code in implementing business requirements.
