Introduction Of Software Testing And Its Types

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

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

The test will execute and verify the test scripts, identify, fix and retest all high and medium severity defects per the entrance criteria, prioritize lower severity defects for future fixing via CR.

Software testing is any activity aimed at evaluating an attribute or capability of a program or system and determining that it meets its required results. [Hetzel88] Although crucial to software quality and widely deployed by programmers and testers, software testing still remains an art, due to limited understanding of the principles of software. The difficulty in software testing stems from the complexity of software: we can not completely test a program with moderate complexity. Testing is more than just debugging. The purpose of testing can be quality assurance, verification and

Manual testing is better than automated testing. All the above mentioned process models are widely used under manual testing, in which human beings perform this sort of testing. Automated testing is done by the computer which reduces the man power but not matter how fast a computer works it never thinks as human being ("Which is better," 2013). Even after a product is developed by using automation testing it cannot be completed without manual testing. A software test engineer must check the result of the automated test manually. Automated test stops even for simple unexpected pop-up dialogue which should be cleared by manual testing. Manual testing requires human judgement in which a human being executes the test cases in order to obtain the desired output. By using this one can find more bugs and fix them where automated testing does not find as many as manual testing. Layout, usability issues and trivial bugs can be identified by manual testing where automated testing cannot ("Which is better," 2013).

This chapter will show the process of testing and some of the test strategies that were used. System testing, acceptance testing and functional testing are all included.

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.

Software testing refers to the process of finding an error of ensuring that particular software meets its specification. The growing complexity of software division into various application demands highly skilled engineers with the appropriate mix of expertise. Testers need to do sampling such as generates a set of test cases to validate against the user

Software Testing is a process in which computer softwares are tested to see if they produce the results that they are expected to produce. It is a process of executing a program with the intention of finding software bugs. It provides us with information about the quality of the system/product/software we are testing. Testing can determine the correctness of the software under observation based on the system requirements but it cannot identify all the defects in the software. This is because testing is always done based on some criteria which include specifications, comparable products, previous versions of the same product, inferences about the expected product, user expectations, applicable laws, relevant standards, etc. Testing identifies software failures in order to discover and correct defects.

Before the QA phases and handling it to the QA team for testing,development team does a series of testing mentioned below which ensures quality and requirements are met.

5. TESTING – This phase verifies whether the system works and meets all of the business requirements defined in the analysis phase

Software testing is a typical procedure of testing in which we are comparing the actual outcome with the expected outcome. Testing of the software is being performed in order to check the correct functionality of the system or project. If the testing will not be performed properly then system may lead to catastrophic or improper results in that particular field. So it’s

Also known as table driven testing framework, Keyword-Driven Automation Framework focused on the development of the data tables and keywords for the test case. Each test script is viewed as a keyword prompted action and the test data directs the testing here. In a keyword-driven test, the functionality of the application-under-test is written in a table in the form of step-by-step instructions for each test where Data Table contains Action to be performed on GUI Objects and corresponding arguments. Each row represents one Test Step. In this method, the entire process is data-driven, including functionality.

Software testing is an important activity in software engineering, as it is used for examining the quality or capability of a software and conforms that it meets the desired output. There are several methods to do software testing, but testing a complex software efficiently is the process of investigating thoroughly, it is not like to follow a procedure or method merely. In complex software it is not possible to discover all the errors. In testing, this type of complex software always creates problem for tester and throws open questions like, “what would be the best strategy that we should follow?” Also, selecting a strategy is important decision as selecting right strategy will allow tester to work effectively and efficiently.
