A powerful and flexible GUI, driven by Test Plans, requires no.Software Testing Levels.There are different levels during the process of testing.In this chapter, a brief description is provided about these levels.Levels of testing include different methodologies that can be used while conducting software testing.The main levels of software testing are Functional Testing.Non functional Testing.Functional Testing.This is a type of black box testing that is based on the specifications of the software that is to be tested.The application is tested by providing input and then the results are examined that need to conform to the functionality it was intended for.Functional testing of a software is conducted on a complete, integrated system to evaluate the systems compliance with its specified requirements.There are five steps that are involved while testing an application for functionality.Steps. Description.IThe determination of the functionality that the intended application is meant to perform.IIThe creation of test data based on the specifications of the application.IIIThe output based on the test data and the specifications of the application.IVThe writing of test scenarios and the execution of test cases.VThe comparison of actual and expected results based on the executed test cases.An effective testing practice will see the above steps applied to the testing policies of every organization and hence it will make sure that the organization maintains the strictest of standards when it comes to software quality.Unit Testing. This type of testing is performed by developers before the setup is handed over to the testing team to formally execute the test cases.Interesting readers question How is testing carried out in a company i.Here is the actual testing process of Software Testing in the.Unit testing is performed by the respective developers on the individual units of source code assigned areas.The developers use test data that is different from the test data of the quality assurance team.The goal of unit testing is to isolate each part of the program and show that individual parts are correct in terms of requirements and functionality.Limitations of Unit Testing.Testing cannot catch each and every bug in an application.It is impossible to evaluate every execution path in every software application.The same is the case with unit testing.There is a limit to the number of scenarios and test data that a developer can use to verify a source code.After having exhausted all the options, there is no choice but to stop unit testing and merge the code segment with other units.Integration Testing.Integration testing is defined as the testing of combined parts of an application to determine if they function correctly.Integration testing can be done in two ways Bottom up integration testing and Top down integration testing.S. N. Integration Testing Method.Bottom up integration.Step Software Testing Process Pdf' title='11 Step Software Testing Process Pdf' />This testing begins with unit testing, followed by tests of progressively higher level combinations of units called modules or builds.Top down integration.Step Software Testing Process Pdf' title='11 Step Software Testing Process Pdf' />A provider of animal research models, as well as a range of biomedical products and outsourcing services, for use in the discovery, development and testing of new.In this testing, the highest level modules are tested first and progressively, lower level modules are tested thereafter.In a comprehensive software development environment, bottom up testing is usually done first, followed by top down testing.The process concludes with multiple tests of the complete application, preferably in scenarios designed to mimic actual situations.System Testing. System testing tests the system as a whole.Once all the components are integrated, the application as a whole is tested rigorously to see that it meets the specified Quality Standards.This type of testing is performed by a specialized testing team.System testing is important because of the following reasons System testing is the first step in the Software Development Life Cycle, where the application is tested as a whole.The application is tested thoroughly to verify that it meets the functional and technical specifications.The application is tested in an environment that is very close to the production environment where the application will be deployed.System testing enables us to test, verify, and validate both the business requirements as well as the application architecture.Regression Testing.Whenever a change in a software application is made, it is quite possible that other areas within the application have been affected by this change.Regression testing is performed to verify that a fixed bug hasnt resulted in another functionality or business rule violation.The intent of regression testing is to ensure that a change, such as a bug fix should not result in another fault being uncovered in the application.Regression testing is important because of the following reasons Minimize the gaps in testing when an application with changes made has to be tested.Testing the new changes to verify that the changes made did not affect any other area of the application.Mitigates risks when regression testing is performed on the application.Test coverage is increased without compromising timelines.Increase speed to market the product.Acceptance Testing.This is arguably the most important type of testing, as it is conducted by the Quality Assurance Team who will gauge whether the application meets the intended specifications and satisfies the clients requirement.The QA team will have a set of pre written scenarios and test cases that will be used to test the application.More ideas will be shared about the application and more tests can be performed on it to gauge its accuracy and the reasons why the project was initiated.Acceptance tests are not only intended to point out simple spelling mistakes, cosmetic errors, or interface gaps, but also to point out any bugs in the application that will result in system crashes or major errors in the application.By performing acceptance tests on an application, the testing team will deduce how the application will perform in production.There are also legal and contractual requirements for acceptance of the system.Alpha Testing. This test is the first stage of testing and will be performed amongst the teams developer and QA teams.Unit testing, integration testing and system testing when combined together is known as alpha testing.During this phase, the following aspects will be tested in the application Spelling Mistakes.Broken Links. Cloudy Directions.The Application will be tested on machines with the lowest specification to test loading times and any latency problems.Beta Testing. This test is performed after alpha testing has been successfully performed.In beta testing, a sample of the intended audience tests the application.Beta testing is also known as pre release testing.Beta test versions of software are ideally distributed to a wide audience on the Web, partly to give the program a real world test and partly to provide a preview of the next release.In this phase, the audience will be testing the following Users will install, run the application and send their feedback to the project team.Typographical errors, confusing application flow, and even crashes.Getting the feedback, the project team can fix the problems before releasing the software to the actual users.The more issues you fix that solve real user problems, the higher the quality of your application will be.Having a higher quality application when you release it to the general public will increase customer satisfaction.Non Functional Testing.This section is based upon testing an application from its non functional attributes.Non functional testing involves testing a software from the requirements which are nonfunctional in nature but important such as performance, security, user interface, etc.Some of the important and commonly used non functional testing types are discussed below.Performance Testing.It is mostly used to identify any bottlenecks or performance issues rather than finding bugs in a software.There are different causes that contribute in lowering the performance of a software Network delay.Client side processing. Imaging Of The Giant Screen Program Action Yt . Database transaction processing.Load balancing between servers.Data rendering. Performance testing is considered as one of the important and mandatory testing type in terms of the following aspects Speed i.Response Time, data rendering and accessingCapacity.Stability. Scalability.Performance testing can be either qualitative or quantitative and can be divided into different sub types such as Load testing and Stress testing.Load Testing. It is a process of testing the behavior of a software by applying maximum load in terms of software accessing and manipulating large input data.
