Functional testing typically defines what the system does. Functional testing verifies a program by checking it against design document. In a software testing company, functional testing is a quality assurance (QA) procedure and a type of testing that bases its test cases on the specifications of the software modules under test.
In functional testing mainly the testing of the functions of module or system is done, it refers to activities that verify a specific action or function of the code. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered.
Types of Functional testing:
Smoke Testing comprises of a non-exhaustive set of tests that aim at ensuring that the most important functions work. The results of this testing is used to decide if a build is stable enough to proceed with further testing.
Sanity testing is a kind of Software Testing performed after receiving a software build, with minor changes in code, or functionality, to ascertain that the bugs have been fixed and no further issues are introduced due to these changes. The goal is to determine that the proposed functionality works roughly as expected.
Regression testing is defined as a type of software testing to confirm that a recent program or code change has not adversely affected existing features. Regression testing is nothing but full or partial selection of already executed test cases which are re-executed to ensure existing functionality work fine.
Usability testing refers to evaluating a product or service by testing it with representative users. Typically, during a test, participants will try to complete typical tasks while observers watch, listen and takes notes. The goal is to identify any usability problems, collect qualitative and quantitative data and determine the participant's satisfaction with the product.

What is system testing?
Testing a system after it has been coded, unit tested, and usually undergone intergration testing. Test cases are written from documentation (functional spec, business rules etc..) and then executed to confirm the software will meet requirments.
What is system testing in manual testing?
System testing is the type of testing to check the behavior of a complete and fully integrated software product based on the software requirements specification (SRS) document. Its a series of different tests whose sole purpose is to exercise the full computer based system. In SDLC, System Testing is perform as the first level of testing where the system is tested as a whole. In System Testing, we test the both Functional as well as Non Functional parameters of Software Testing. System testing involves testing of following: Testing the fully integrated applications including external peripherals in order to check how components interact with one another and with the system as a whole. This is also called End to End testing scenario. Verify thorough testing of every input in the application to check for desired outputs. Testing of the user's experience with the application. . That is a very basic description of what is involved in system testing. You need to build detailed test cases and test suites that test each aspect of the application as seen from the outside without looking at the actual source code. Every software testing company consider all these things while performing system testing.
What are the softwares or languages that i should learn along with software testing tools like QTP to become a good software testing engineer?
The fact is that there is no END to learning software testing. however you can be proficient and in great demand if u have these skills. Functional Testing: Read CSTE book of knowledge - for testing concepts. Winrunner for automation QTP for automation IBM's Rational for automation Performance testing: Loadrunner for automation Silktest for automation Rational Suite for automation
What is the difference bitween object oriented testing and conventional testing?
Conventional testing is the traditional approach to testing mostly done when water fall life cycle is used for development, while object oriented testing is used when object oriented analysis and design is used for developing enterprise software. Conventional testing focuses more on decomposition and functional approaches as opposed to object oriented testing, which uses composition. The three levels of testing (system, integration, unit) used in conventional testing is not clearly defined when it comes to object oriented testing. The main reason for this is that OO development uses incremental approach, while traditional development follows a sequential approach. In terms of unit testing, object oriented testing looks at much smaller units compared to conventional testing.
Functional and non functional requirements of web search engine?
There are many functional and non functional requirements of a web search engine. The non functional requirements would be the design you see, while the functional requirement would be the search bar.
What is functional testing used for?
Functional testing is used for quality assurance (QA). Function testing describes what a system does. There are five steps involved with functional testing.
What is the difference between validation testing and system testing?
Validation testing is to test software if it meets its stated requirements. System testing is the testing of Software and Hardware together and to find out they both can work together to be successful application.
What is non functional testing in software testing?
It is testing of "how" the system works. Non functional testing may be performed at all test levels. The term non-functional testing describes the tests required to measure characteristics of systems and software that can be quantified on a varying scale, such as response times for performance testing. Types of Non-functional testing are performance testing, load testing, stress testing, usability testing, maintainability testing, reliability testing and portability testing.
What is the Difference between functional and functionality testing?
System testing has classifications like functional and non functional testing. Hence the functional testing is a part of system testing. System testing allows the testers to test the typical end product. Every single module, interface and every minute detail are needed to be tested in system testing. Functional testing is aimed at testing the functionalities of the product being tested. These functionalities include volume, stress, load, security, scalability, performance etc. Hardware and software is not concerned with functional testing. Functional testing involves testing of functional requirements as per the specification. On the other hand, system testing involves testing the system as a whole. This may involve testing of proper installation and uninstalling of the application. System testing tests for all internal and external components that make the system.
What is full regression testing?
Regression testing is a type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes such as enhancements, patches or configuration changes, have been made to them.
Which testing procedure according to which modules and sub modules are tested and test case verification is done?
Functional Testing
What is the difference between Mobile Testing and Mobile Application Testing?
Mobile testing is the process of testing mobile devices and their components, such as hardware, software, and networks. It is performed to ensure that the devices meet the required quality standards and are ready for release to the market. Types of tests - Hardware testing, software testing, network testing Examples of tests - Battery life testing, performance testing, security testing Mobile application testing, on the other hand, is the process of testing mobile applications to ensure that they meet the functional and non-functional requirements of the users and the business. It is performed to identify and fix any bugs or defects in the applications before they are released to the public. Types of tests - Functional testing, non-functional testing Examples of tests - Installation testing, usability testing, performance testing I hope this information is helpful.
Are there any vendors who offer testing services independently?
Yes there are many. But make sure you partner with someone who can provide customized core testing services. Look for companies offering customized testing at multiple levels including functional testing, integration testing, and regression testing.
What is functionality testing?
It's a type of GUI testing where functionality of an application is tested.To be specific:Testing of all features and functions of a system [software, hardware, etc.] to ensure requirements and specifications are met.Functionality testing of software is testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. Functionality testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic
Difference between integration testing and regression testing?
Integration testing - It is the phase of software testing in which individual software modules are combined and tested as a group. It follows unit testing and precedes system testing.Regression testing is a type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes such as enhancements, patches or configuration changes, have been made to them.
What is pilot testing in software?
Functional testing is a process of testing all the functionality of an application.When we create a software, we create it keeping the users of that software in mind. Functional testing test whether the application fulfills the requirement of the user. It means to check whether the functionality of an application are working as expected or not. For example, Login functionality, Compose mail functionality, Delete mail functionality,etc. See the related question below.
What is a benefit of combined development testing and operational testing?
Combining development testing and operational testing allows for software testers to do both white box and black box testing. That is, it allows for the code to be tested, while functional requirements are also tested, making for a more smooth development cycle.
