Developmental Testing Is A Component Of Extreme Programming

Testing of the entire system will be performed to verify that all parts and counterparts are functional. This is the testing that is made prior to release. Tests performed in this stage verify for the following:

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

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.

Testing is the next phase of the implementation phase. A comprehensive testing program includes a stepwise process starting with unit testing, followed by testing of group components called integration testing and concluded with entire systems test (Satzinger et al., 2004, p. 640). Individual units or modules are tested prior to integration with more advanced modules, using driver modules. Once a set of modules are put together, integration testing can take place. These test include checking for interface compatibility, run-time exceptions, parameter values and unexpected state interactions (Satzinger et al., p. 644-645). Jeff Theobald suggests that an effort should be made to concentrate not on just errors in a single application or module, but also the system as a whole and between systems (Theobald, 2007). After these tests are completed, the project goes on to system testing. System testing often involves daily “build and smoke” tests, where the system is set to run and is observed for “smoke” or errors (McConnell, 1996). The TPI credentialing system was tested in this manner. The project made it through the first two testing

The initial and most important step of the testing phase is creating the test plan. The test plan should include what features and functionality will be tested based on the confirmed requirements. The next step is unit testing or code review. Unit testing involves the QA person testing the code on their machine. Once code has passed the unit test, it will then be released to the testing environment for system testing. The QA person can then test the integration of the different modules of the code as a program rather than separate parts as well as to find and report bugs and any data inaccuracy. The next phase of testing is the user acceptance test. In this phase the users test the program for functionality and data accuracy. The test phase isn’t a linear phase, more of a circular, back and forth between the developers and the QA people. After all phases have passed, the next step would be to open a change

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

Different testing techniques like Boundary value analysis, equivalence testing etc. can be applied with ET

Continuous testing ensures changes do not break the existing operations and provides sufficient time to accommodate changes

In testing phase, the code from the coding phase is tested against the requirements gathered in the requirements and analysis phase. In this phase the following tests are done on the system.

The testing phase is one of the final stages of the development process and this is the phase where the final adjustments are made before presenting the completely developed software to the end-user.

In this cycle, the main aim is to test the application by applying different testing procedures in all possible ways. Preparation of test cases document which includes all the requirements mentioned in the release requirement document prepared by Business Analyst (BA). Executing of test cases checklist, which includes the main functionality of the application.

Phase Five – Testing - The system is now built and ready to be tested to be sure that the system has complete functionality of all systems that were designed. The testing begins with the programmers who perform tests called stub testing. This form of testing starts by checking the series of input to make sure that they return the proper outputs. It may also check to make sure that incorrect information is handled properly as well. Next it goes to the development team. They test the modules to make sure that they work correctly when they are put together. This is called unit testing. The development team

The testing chapter will explain why applications must be tested, methods and tools used for testing and the testing

Software quality control (SQL), which is a set of activities, encourages ensuring the highest quality in software products. It contains activities relating to reviews such as requirement review, design review, code review and also activities relating to testing such as unit testing, integration testing, system testing and acceptance testing. Main purpose of SQL is to ensure that the developing software meet all the specifications. At this stage, our group had reviewed software requirements and making sure to achieve all by the time of software development sprint end. Other reviews such as design, codes are going to be well analyzed in later sprint and all the testing types are going to be executed in order to ensure that all the solutions are well tested. Software testing will be done during every development processes in order to assess features and quality of the software. Different
