Role Of Testing For Software Quality Assurance & Black Box Testing

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

There are two common strategies for integration testing. These strategies are top-down & bottom-up. The top-down approach tests the highest-level code first down to the lowest level codes. This show defects at the top level of the software earlier in the process. The bottom-up integrated testing method test from the sub-units to the main-units of the program.

multiple components. • integration Testing: It is a systematic technique for constructing the program structure while at the same time conducting tests to uncover errors associated with in the interface. It takes the unit

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

Penetration test is software testing on a system that looks for security hole or vulnerability. The main goal is to identify the high-risk vulnerabilities and fix it before attacker fined it.

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

4. Development and Testing – This step involves using the final system design to acquire or develop the system. Testing of units, integration, performance, system, and acceptance are done to ensure system functionality and the sponsor’s requirements and that all segments/structures, communications, applications, procedures, and documentation are in place, tested, and integrated. End users are implemented to verify and thoroughly test that the system functions as required.

White box testing approach is used to ensure the quality of the components in the web application. This is essentially done by the developers who have implemented the requirements and have knowledge of the functionality. In addition, during the iterative development the business analysts who have written the business use case are also involved in this white box testing when the component is fully implemented. This quality control process eventually leads to assurance of quality. The QA process also verifies all documents are available in the project repository. This includes the versioned project plan, weekly bug lists i.e. open and closed bugs, enhancement request that need to go through

Functional Testing is basically testing software based on its functional requirements. Meaning it makes sure that the SUT (System Under Test) or program physically works the way it is intended. Now that there is a basic understanding of what Functional Testing is by the definition provided above; How about going more In-depth on the topic.

This stage of the testing is important to the finished product, as it verifies whether the project meets the functional, technical and system requirements. The testing must be conducted in a similar environment in which resembles the production

A/B Testing: It is the most common testing type. It is a kind of split testing and it is defined as the process of splitting website into two pages and test them against each other (the original page and a variation page) in order to see which page produces more

Structural testing is often referred to as ‘white box’ or ‘glass box’ or ‘clear-box testing’ because in structural testing we are interested in what is happening ‘inside the system/application’.

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 design of software tests is mostly based on the testers’ expertise, while test automation tools are limited to execution of pre-planned tests only. Evaluation of test outputs is also associated with a considerable effort by human testers who often have imperfect knowledge of the requirements specification.
