System Testing

The process of testing the complete and integrated software product to meet specified requirements is said to be System Testing. The main aim of this testing is to test the whole software product which is already integrated. It is the third level of software testing. Independent software testers will perform this testing.

Working Process of System Testing

• Initially, it will perform testing on fully integrated applications to verify that the interaction is made perfect with the system.
• To Optimize each and every input of the application or product to get the expected output
• Finally, make sure that the application got the desired output which will be ready for the final level of testing

Types of System Testing

It is broadly divided into two types namely Functional Testing and Non-Functional Testing

Again Functional Testing is divided into many types

• Acceptance Testing
• Beta Testing
• Integration Testing
• Interface Testing
• Regression Testing
• System Testing
• Sanity Testing
• Smoke Testing
• Unit Testing

Non-Functional Testing is also divided into many types

• Compatibility Testing
• Compliance Testing
• Install Testing
• Localization Testing
• Performance Testing
• Recovery Testing
• Reliability Testing
• Security Testing
• Usability Testing

Among the above testing types, this testing mainly involves for following types

• Usability Testing
• Load Testing
• Regression Testing
• Recovery Testing
• Migration Testing

Types of System Testing

Methods of System Testing

According to software testing, there are 3 methods of testing available namely

• Black Box Testing
• White Box Testing
• Grey Box Testing

Among these three methods, this testing will come under the Black Box Testing Technique

Advantages

• It performs testing on end-to-end scenarios of the system
• This testing helps to determine the errors or bugs before the product goes live
• It helps in testing both application and business requirements

Disadvantages

• As it needs to test the whole system it requires a lot of time
• Depending on the business requirements and application architecture cost may also increase

Functional Testing Vs Non-Functional Testing – W3Softech

Here we provide you the blog of functional testing vs non-functional testing with a brief explanation and examples including types and tools…

Functional Testing:

Functional Testing is defined as the testing which tests the functions of a software application and checks whether the output results are matched with expected results.

Steps for working progress of Functional Testing:

• It performs testing on main functions
• Identifies the functions and its operations
• Checks the accessibility of the system
• It executes the test cases
• Checks the error conditions
• Finally compares the output results with the expected results

Non-Functional Testing:

Non-Functional Testing is used to test the performance of software application based on customer’s expectations and under specific conditions.

Steps for working progress of Non-Functional Testing:

• Initially tests the performance of a software application
• Optimizes the software application
• Provides appropriate measurements over the software product
• Improves the behavior of a software application
• Provides more reliable and flexible output results

Functional Testing Vs Non-Functional Testing – W3Softech

Functional Testing Vs Non-Functional Testing

Parameters	Functional Testing	Non-Functional Testing
Functionality	It tests what the product does and checks the operations of the software application.	It tests the performance of the software application under specific conditions.
Execution	Generally, it is used to perform before non-functional testing.	It is used to perform after functional testing.
Focus	It performs based on customer’s requirements.	It performs based on customer’s expectations.
Requirement	Functional Requirements are very easy to define.	Non-Functional Requirements are difficult to define.
Usage	It helps to validate the test functions of the software application.	It helps to validate the test performance of the software application.
Objective	It checks whether the actual results are working according to the expected results.	It checks whether the performance of the software application is working under specific conditions.
Manual Testing	Functional Testing is easy to execute by Manual Testing.	Non-Functional Testing is hard to execute by Manual Testing.
Automation Testing	Functional Testing is hard to execute by Automation Testing.	Non-Functional Testing is easy to execute by Automation Testing.
Example Test Case	Check login functionality like if the inputs are valid then app login functions correctly.	After the login, the dashboard should load in 3 seconds.
Testing Types	Beta/Acceptance Testing Integration Testing Interface Testing Regression Testing System Testing Sanity Testing Smoke Testing Unit Testing	Compatibility Testing Compliance Testing Install Testing Load Testing Localization Testing Performance Testing Recovery Testing Reliability Testing Security Testing Stress Testing Usability Testing Volume Testing

Functional Testing Types, Tools and Examples - W3Softech

What is Functional Testing? Types, Tools and Examples – W3Softech

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 it 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.

It involves a black box testing technique. The internal logic of the system must be tested. It can be done in two ways either through Manual Testing or Automation Testing.

Working Process of Functional Testing:

• Initially performs the testing on main functions of an application
• Identify the functions of a software application which need to be tested
• It involves basic usability of User Interface, APIs, Security, Database, Server Applications and Functionality of the AUT
• This testing checks the accessibility of the system
• Execute the test cases
• It helps to verify error conditions like any error messages are occurring
• Finally, make a comparison between output results and the expected results

Functional Testing Types, Tools and Examples

Types of Functional Testing:

• Beta/Acceptance Testing
• Integration Testing
• Interface Testing
• Regression Testing
• System Testing
• Sanity Testing
• Smoke Testing
• Unit Testing

List of Functional Testing Tools:

The major testing tools are listed below

• Coded UI Test
• JUnit
• QTP (Quick Test Professional)
• Sahi
• Selenium
• soapUI
• Telerik Test Studio
• Test IO
• TimeShiftX
• UFT
• Watir
