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.
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.
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.
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.

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.
Well, honey, the Business Analyst in the software testing life cycle is like the detective of the team. They gather requirements, analyze them, and make sure the testing process aligns with what the business needs. Think of them as the bridge between the business side and the testing team, making sure everyone's on the same page and delivering a product that actually works.
Functional testing is used for quality assurance (QA). Function testing describes what a system does. There are five steps involved with functional 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.
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.
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.
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.
Functional Testing
A comprehensive functional fitness testing protocol typically includes assessments of strength, endurance, flexibility, balance, and agility. These components help evaluate overall physical fitness and identify areas for improvement in an individual's functional abilities.

Mobile testing : Mobile Testing encompasses mobile application testing, mobile device testing, mobile phone testing, mobile system testing.Mobile application testing : Mobile application testing is a process by which application software developed for hand held mobile devices is tested for its functionality, usability and consistency. Mobile applications either come pre-installed or can be installed from mobile software distribution platforms. Mobile devices have witnessed a phenomenal growth in the past few years.
To ensure effective implementation of PBE functional testing in our software development lifecycle, we should establish clear testing objectives, define test cases based on user behavior, automate testing processes where possible, regularly review and update test cases, involve stakeholders in testing, and continuously monitor and improve the testing process.
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.
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
