Testing, Testing And User Acceptance Testing

The first milestone will be concept approval. During this phase, feasibility studies and basic system concepts have been approved by the management. The project is on course to proceed according to the detailed requirements. The next milestone is requirements review. During this stage, requirement specifications are ready, correct, and approved for input to the design. The next milestone will be preliminary design review here the architectural design meets all product requirements. Critical design review will then follow. During this phase, the detailed designs are approved and suitable for the development of test cases. The next milestone will be the test plan review, which involves reviewing the test plan to ensure product features are satisfactory. The next milestones will be tested readiness review, system test review, operational readiness review, and operational product

Testing is when you check for faults, take measures to check quality, look at reliability and look at the

A test schedule will determine when key test should be performed. This plan will outline the details the project will follow for testing. Also, it will include the strategies and process involved in testing the system with live data. This test plan will also include when to test. Testing should always be done throughout the system development until the system is complete. This will help detect problems early and can allow time for feedback on the development of the system. The test plan will also include who will do the testing. As a system analyst it is also the responsibility to assign testing duties for each stage of the testing process. In addition, the test plan should also include what will be tested (McGregory, n.d.). “Before the system is put into production, all programs must be checked, checked with test data, and checked to see if the modules work together with one another as planned” (Kendall & Kendall, 2011, p. 526).

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.

If they pass the testing then they are progressed to the production area where they are finally put into the production and here the final system is set up.

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

Evaluate testing approaches and make recommendations for improvements to system, system integration, acceptance, and operability level (performance and stress) testing.

This is the phase where all kinds of testing are performed. We have testers that test the code, functionality, validation of fields, data validation, frontend-backend connectivity etc. when we start this phase. A gives a brief demo to the customer. The product is not fully tested but he still does the demo.

Next Iteration: During the system testing if there are major changes from the client then such changes are included in the next Iteration.

The next stage will be including the testing and evaluation period. This step will ensure that the testing

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

Testing is vital to success of any system. Testing is done at different stages within the phase. System testing makes a logical assumption that if all phases of the system are correct, the goals will be achieved successfully. Inadequate testing at all leads to cause of errors that may come up after a long time when correction would be extremely difficult. Another objective of testing is its utility as a user –oriented vehicle before implementation. The testing of the system was done on both artificial and live data.

In software development, there are various types of methods that developers follow in order to produce valuable software. From the many types of methods that exist today, the industry standard that is mostly followed today is the software development lifecycle (SDLC). The SDLC is a process that software development companies utilize in order to design, develop and test software during production. Within the SDLC, there are different test models that developers can utilize based on their business and development requirements. Currently today, the most common models include the waterfall, iterative, spiral and V-model. Regardless of the model that a developer decides to utilize, all the phases will be the same, which would begin with the first step and that is the requirement gathering and analysis phase.
