Advantages And Disadvantages Of WBT

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

As the world became more and more dependent on technology with each passing day, software automatically became an important organ for development. Since software is needed almost everywhere today, its development is a highly intelligent and precise process, involving various steps. Known as software development life cycle, these steps include planning, analysis, design, development & implementation, testing and maintenance. These steps go on to create the perfect software for clients. ”

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.

The reason that qualitative methods are used so infrequently in software engineering lies in its foundations as a scientific and engineering discipline. An inherited technical interest in improving practice is associated with a preference for quantitative research approaches that lend themselves to measuring causal relationships for successful software process improvement. However, studying software engineering is a complex undertaking not just because of its technical aspects, but also “from the awkward intersection of machine and human capabilities, and from the central role of human behavior in software development” (Seaman 1999, p.557).

Once the product is developed, testing should be performed on the system against the product requirements. The objective of the testing is to find defects within the system and confirm whether the system operates as expected. Testers will use test scripts, which were designed in the previous development stage, to execute the test. If defects are identified, the developers should work to resolve them prior to the software being implemented.

In this strategy some test cases are generated as input conditions that fully execute all functional requirements for the program. This testing has been uses to find errors in the following categories:

The expected input and output values are defined, and test cases are written using JUnit and Selenium tools.

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 meets its required

Software testing is an important part of software development. In order to enhance the quality of the software, software testing has always been the crucial part in finding faults of a software.Software behaviour is always verified by a test oracle.The test oracle is a way to find the sucess and failure of a test. Test oracles provides a valid mechanisms to test the expected behaviour of any software against the input provided for the test in the software specification so that actual results can be verified.Test automation also requires automatic test oracles.

It uses first order, second order or higher order logic theorem. The main aim of this method is to detect the error into software execution code. This error could be analyzed in the software requirement process. All the high level requirements are consistent and satisfies the conformance of standard.

Abstract—At the end of 20th century software industry started booming. From then, not only it has never looked back, but it’s continuously growing at a very high rate. Customers always prefer quality software products and hence software quality is at the heart of any successful business that develops software. Software testing enables once to quantify the software quality and hence testing has become an integral and very important part of the software development life cycle. There’s this saying that “humans make mistakes all the time” which should enough to conclude that the software developed by humans needs to be tested of bugs and intended functionality to ensure a high quality product and hence Software Testing plays an important role

The validation improves the performance of testing by increasing the confidence in the quality issues of the software.

Also known as Glass box Testing. Internal software and code working should be known for this type of testing. Tests are based on coverage of code statements, branches, paths, conditions.

Sometimes software testing is compulsory because in the software there is some faults and errors. We can not avoid the faults and this error.
