Structural Testing And Component Integration Testing Essay

Unit testing is a type of testing that will test the code of the program. This will test the functions or methods within the program to ensure that they work as they should in compliance to the requirements specification. This type of testing is first to be conducted in the testing stages, right before the integration testing. The software developers will be the ones who will do the unit testing, this type of method is referred to as ‘White-Box’ testing. A benefit of having the actual developers doing this type of testing is that the unit testing can be done throughout the entire development process, for example, they can conduct the unit testing after they make any changes to a method/function or even after creating a new method. The allows

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

For static testing techniques, reviews are the most important techniques to understand the application requirements, design, plan, and analysis. The document reviews are included in such user requirements document, design document, test plan document, or user manual document.

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:

Fabricated test data is prepared and integrated into the program, it is run through the application and the results are compared to the results that are expected to be obtained. The test deck method depends a lot on the abilities of the auditor to anticipate and capture all deviations and exceptions. The auditor must be able to find and use different scenarios that may arise in order to detect errors. An auditor must be able to analyze the data appropriately and carefully so that any errors are not overlooked. Auditors can use another technique similar to the test deck method. The test deck method is used by not incorporating it with live data. However, integrated test facility method is used the same way except that it is incorporated with live data and is run through the client’s system along with normal transaction processing. The last technique used is called parallel simulation. With this technique the auditor uses audit software to reproduce a part of an application or the entire application to test data on. The data that is run on the client’s original application is used again and run on the reproduced program and the results are compared and any errors analyzed.

\label{s:test} There are many issues that were faced during testing of the module. Following are the issues faced, test strategy used and the solutions that were implemented to remove them. The testing in this thesis can be divided into three parts, which are:

3.1.6 Vulnerability testing: by conducting vulnerability tests allows the organization to see if the system can be penetrated and if there are any weak areas in the system. If vulnerabilities are found this allows the organization time to fix the problem.

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.

In the testing area the code is tested and if there’re are problems then they are re-developed.

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

When a test of a tool is conducted, this method begins by reviewing the tool documentation of the tool to be acquired. If there is no documentation, an analysis of the tool is conducted. This method is reviewed by both the vendor and the testing organization, but this process can be time-consuming.

One of the key success factors in factory witness testing is to have a clearly defined test protocol in the purchase specification. This ensures that each supplier is providing a common test program allowing a better comparison of each manufacturer’s value proposition. In addition it prevents substandard testing approaches from being submitted after award of the order. To achieve these goals the PI team will work with the project team to fully specify the testing that is desired at the manufacturer’s facility.
