Software Testing For Software Development Lifecycle

The Verification and Validation, or V-model, Software Development Paradigm will be used to define the development life cycle of the software product. This paradigm was chosen because it allows us to test the software during each stage of the project in an inverse way. Also, because the validation and verification of

This chapter focuses on conducting the test case on each software unit and showing the obtained results in the form of snapshots taken where each snap describes the process being done.

Test Plan: The software is tested using two levels of testing viz. black box testing and white box testing. White box testing could be carried out in three different phases viz. unit testing system/integration testing and validation testing. • Unit Testing: Unit testing, also known as Module Testing, focuses verification efforts on the module. The module is tested separately and this is carried out at the programming stage itself.Unit Test comprises of the set of tests performed by an individual programmer before integration of the unit into the system. Unit test focuses on the smallest unit of software design- the software component or module. Using component level design, important control paths are tested to uncover errors within the boundary of the module. Unit test is white box oriented and the step can be conducted in parallel for

For the system, which should never be failed, the reliability test of the software should be done. For this, the black box and white box testing should be done on the software. After the successful development of the software, a beta version should be released. The errors and bugs related to the security and functional requirements can be find out in an easy manner.

Programming testing is the methodology of executing a program or framework with the purpose of finding faults. Testing is a procedure of affirming that item is working as per the requirments, fulfilling the client needs. Programming testing gives a way to decrease errors, cut maintenance and general programming costs. Various programming testing strategies, techniques, and systems have developed in the course of the most recent couple of decades promising to improve programming quality. Programming testing is vital part in the product development life cycle. Two regular methodologies are white box testing and discovery testing. There are diverse scope measure for testability to the source code, for example, statement coverage, branch coverage and condition coverage. In the branch coverage we ensure that we execute each branch in any event once For conditional branches, this implies, we execute the TRUE branch in any event once and the FALSE branch in any event once conditions for conditional branches can be compound boolean expressions a compound boolean

It plays a crucial role in the development of an application. Testing should be done to validate the product whether it met all the requirements and to check whether it is being developed according to design or not.

This test plan describes the testing approach and overall framework that will drive the testing of the Foo-Com Enterprise. The document introduces:

It is the major quality control which is used during software development life cycle. The basic function of software testing is to identify errors in the software. During the requirement analysis and the software design phase, the output of a document is usually textual and non-executable. Once the design phase completed successfully then coding phase start, the computer programs are available that can be achieved for testing purposes. It is implies that testing means not only to uncover errors introduced during coding, but also the errors introduced during the previous phases. Thus, the main goal of software testing is to find requirement, design, and coding errors in the programs. To perform testing consequently, different levels of testing

Analyze, develop and document the application test plans based on software requirements and technical specifications.

The main aim of software development is to produce high quality software. Superior quality software has characteristics like low cost, reliability and user satisfactory. Software testing is the process of assessing the software in order to discover any defects and determine if the software satisfies all the requirements. It is a step by step process of planning the requirements, executing the program and finding any defects to verify that the program

Gathered specifications and requirements to develop Test Plans and to create Test Cases using Quality Center.

In this type of testing the one, one and small part of program is testing and find the errors during this testing when the errors found and highlight the errors and later fix these errors. The testing of this type is easy and take less time. When this step of testing is completed then the next step of testing is performed.

Test (or) Code coverage is a measure used to describe the degree to which the source code of a program is tested by a particular test case/suite. In other words, Code coverage is a way of ensuring that your tests are actually testing your code. Coverage acts as an effective approach to determine the efficiency of your test case (or a set of test cases); knowledge of the internals of the object being tested shall be known to (white/black-box) test and helps in test case optimization.

There are a number of reasons why software testing with real users ' views are important, even if the software is still being developed. One of the main reasons is that testing can bring value to the end product. Software testing demonstrates that defects are detected in the application that was developed. The process validates and verifies the software in order to ensure that the product meets the highest business and technical requirements that directed its design and development in the first place. The stakeholders involved in development or purchasing of software spend tremendous amount of resources in doing so and tend to want the software testing efforts to succeed and ensure that a quality product be produced. Hence, it is important for them to test the software in order to validate their implementations.

This chapter will show the process of testing and some of the test strategies that were used. System testing, acceptance testing and functional testing are all included.
