Functional testing is an integral part of software development which ensures software quality by performing end to end testing. In other words functional testing services ensure software is developed as specified in requirement document. As the name specifies functional, software is tested of its functionality or feature. Functional tests are taken by providing an input and observing the outputs. It is generally performed in controlled environment. Input parameters are specified considering the production environment so the real time feed is provided to obtain the realistic results which are later compared with expected result sets. Functional software testing is a kind of black box testing wherein least consideration is given to internal source code. Functional testing is uses interfaces like GUI, API, CLI for executing test cases.
Following approach may be adopted for carrying out functional testing:
a) Understanding software functions/features on the basis of design document.
b) Developing input set which are feed into test cases on the basis of step A.
c) Output set prediction based on step A.
d) Developing and conducting tests as per test cases.
e) Result Analysis and Reporting.
Functional test can include the testing of main Program Functions and Exception handling, Usage, Accessibility and Portability, Vulnerability, Recovery etc. Functional services assists in validation of software quality and these are carried out automatically to perform regression test. Various automated tools are available to do the same. Automation makes it possible to take care of scope creep in software requirements, according to which software requirement keep changing with time and needs running iterative test cycles again and again. Automation tools helps to deliver the application faster and are reliable.
Functional testing is done by running programs or scripts for a group of classes providing discrete features to overall software module. Functional software testing is carried out as a part of all software development approaches be it conventional Software development lifecycle approach or Agile/Scrum methodologies. Functional services company provides unbiased and accurate testing services to its customers. Functional services companies in India are flourishing from decades by providing offshore services through individuals with years of experience is manual and automated testing. Functional services India understand and manage the efficiency of the test strategies and planning. Quality and cost advantages can be leveraged by outsourcing functional testing tasks offshore while keeping focus on development and innovation. Offshore companies provide functional expertise in domains like banking, finance, insurance, airlines, healthcare etc. Functional testing teams in India specializes in tools like Selenium, Mercury, and QTP etc and ensure creation of efficient test plans, test cases to execution of test cases and analyzing the and rectifying the results to deliver 100% bug-free Software applications which are built to deliver desired functionalities. Functional services India understand and manage the efficiency of the test strategies and planning.
