What is Software Testing?
Software testing is a process of executing a software product or program or application or web-site with the intent of finding the software bugs. The same can also be called as the process of validating and verifying process.
Software testing is done to verify and validate to meet or works as expected a software product or program or application or web-site the business and technical requirements that guided it’s design and development.
In the Software Testing we have many types of testing which can be brought in to two major categories: MANUAL TESTING and AUTOMATED TESTING.
This is a testing approach that makes use of testing tools and/or programming to run the test cases using software or custom developed test utilities. Most of the automated tools provided capture and playback facility, however there are tools that require writing extensive scripting or programming to automate test cases.
Black Box testing
Black box testing is a software testing method where the testers are not required to know coding or internal structure of the software. Black box testing method relies on testing software with various inputs and validating results against expected output.
Browser compatibility Testing
Its one of the sub types of testing of compatibility testing performed by testing team. Browser compatibility testing is performed for web applications with combination of different browsers and operating systems.
Compatibility testing is one of the test types performed by testing team. Compatibility testing checks if the software can be run on different hardware, operating system, bandwidth, databases, web servers, application servers, hardware peripherals, emulators, different configuration, processor, different browsers and different versions of the browsers etc.,
Functional testing is a formal type of testing performed by testers. Functional testing focuses on testing software against design document, Use cases and requirements document. Functional testing is a black box type of testing and does not require internal working of the software unlike white box testing.
Glass box Testing
Glass box testing is another name for White box testing. Glass box testing is a testing method that involves testing individual statements, functions etc., Unit testing is one of the Glass box testing methods.
Integration testing also known as I&T in short, in one of the important types of software testing. Once the individual units or components are tested by developers as working then testing team will run tests that will test the connectivity among these units/component or multiple units/components. There are different approaches for Integration testing namely, Top-down integration testing, Bottom-up integration testing and a combination of these two known as Sand witch testing.
Load testing is a type of non-functional testing; load testing is done to check the behavior of the software under normal and over peak load conditions. Load testing is usually performed using automated testing tools. Load testing intends to find bottlenecks or issues that prevent software from performing as intended at its peak workloads.
Performance Testing is a type of software testing and part of performance engineering that is performed to check some of the quality attributes of software like Stability, reliability, availability. Performance testing is carried out by performance engineering team. Unlike Functional testing, Performance testing is done to check non-functional requirements. Performance testing checks how well software works in anticipated and peak workloads. There are different variations or sub types of performance like load testing, stress testing, volume testing, soak testing and configuration testing.
Regression Testing is a type of software testing that is carried out by software testers as functional regression tests and developers as Unit regression tests. Objective of regression tests are to find defects that got introduced to defect fix(es) or introduction of new feature(s). Regression tests are ideal candidate for automation.
Smoke Testing is a type of testing that is carried out by software testers to check if the new build provided by development team is stable enough i.e., major functionality is working as expected in order to carry out further or detailed testing. Smoke testing is intended to find “show stopper” defects that can prevent testers from testing the application in detail. Smoke testing carried out for a build is also known as build verification test.
Sanity Testing is a type of testing that is carried out mostly by testers and in some projects by developers as well. Sanity testing is a quick evaluation of the software, environment, network, external systems are up & running, software environment as a whole is stable enough to proceed with extensive testing. Sanity tests are narrow and most of the time sanity tests are not documented.
Scalability Testing is a non functional test intended to test one of the software quality attributes i.e. “Scalability”. Scalability Testing is not focused on just one or few functionality of the software instead performance of software as a whole. Scalability testing is usually done by performance engineering team. Objective of scalability testing is to test the ability of the software to scale up with increased users, increased transactions, increase in database size etc., It is not necessary that software’s performance increases with increase in hardware configuration, scalability tests helps to find out how much more workload the software can support with expanding user base, transactions, data storage etc.,
Static Testing is a form of testing where in approaches like reviews, walkthroughs are employed to evaluate the correctness of the deliverable. In static testing software code is not executed instead it is reviewed for syntax, commenting, naming convention, size of the functions and methods etc. Static testing usually has check lists against which deliverables are evaluated. Static testing can be applied for requirements, designs, test cases by using approaches like reviews or walkthroughs.
Stress Testing is a type of performance testing, in which software is subjected to peak loads and even to a break point to observe how the software would behave at breakpoint. Stress testing also tests the behavior of the software with insufficient resources like CPU, Memory, Network bandwidth, Disk space etc. Stress testing enables to check some of the quality attributes like robustness and reliability.
System Testing includes multiple software testing types that will enable to validate the software as a whole (software, hardware and network) against the requirements for which it was built. Different types of tests (GUI testing, Functional testing, Regression testing, Smoke testing, load testing, stress testing, security testing, stress testing, ad-hoc testing etc.,) are carried out to complete system testing.
System Integration Testing
System Integration Testing known as SIT (in short) is a type of testing conducted by software testing team. As the name suggests, focus of System integration testing is to test for errors related to integration among different applications, services, third party vendor applications etc., As part of SIT, end-to-end scenarios are tested that would require software to interact (send or receive data) with other upstream or downstream applications, services, third party application calls etc.,
Unit Testing is a type of testing that is performed by software developers. Unit testing follows white box testing approach where developer will test units of source code like statements, branches, functions, methods OR class, interface in OOP (object oriented programming). Unit testing usually involves in developing stubs and drivers. Unit tests are ideal candidates for automation. Automated tests can run as Unit regression tests on new builds or new versions of the software. There are many useful unit testing frames works like Junit, Nunit etc., available that can make unit testing more effective.
User Acceptance Testing (UAT)
User Acceptance testing is a must for any project; it is performed by clients/end users of the software. User Acceptance testing allows SMEs (Subject matter experts) from client to test the software with their actual business or real-world scenarios and to check if the software meets their business requirements.
White Box Testing
White box testing is also known as clear box testing, transparent box testing and glass box testing. White box testing is a software testing approach, which intends to test software with knowledge of internal working of the software. White box testing approach is used in Unit testing which is usually performed by software developers. White box testing intends to execute code and test statements, branches, path, decisions and data flow within the program being tested. White box testing and Black box testing complement each other as each of the testing approaches have potential to un-cover specific category of errors.
