Software Testing Fundamentals

Software testing method for testing software

This article is related to software testing in this article the fundamentals relate to testing are described. This articles present ideas of testing in simple language for those who are interested in career of software testing. For every software project we see, there is an inherent conflict of interest that occurs as testing begins.

The people who have built the software are now asked to test the software.  The main idea of testing is vested interest in demonstrating that the program is free of errors i.e. free from error, that it works according to customer requirement, and that it will be completed on schedule and within budget. Each of these interest mitigate against thorough testing.


Software testing Methods


Software testing is a major phase which takes place during software development process. Testing ensures quality of software product. These are different models used for testing. There are many readymade packages or software tools available for implementation of testing .In this article we are describing different methods for how to implement testing and their various types.

The goal of testing is to find out errors. A software engineer should develop or design software which should be flexible to test. The testing implemented software should be flexible to test. The testing implemented for the software should find out maximum errors in minimum efforts and time. There are certain definitions and concepts which are the basic concept in software testing. In this article we will discuss and elaborate each in lucid language.



Software testability is also said or is defined as “how easily we can test program in less time and efforts. The testing is easy and less effort so it can be find out errors



“This ability helps to easy operate “the better it works, the more efficiently it can test”. If a system it can be tested “.if system is designed and implemented with quality in mind, relatively few bugs will block the execution of tests, allowing tested “ .If a system is designed and implemented with quality in mind ,relatively few bugs will block the execution of tests ,allowing testing to progress without fits and starts.




    “What u can see u test” .when inputs are provided properly testing become easy and error free. Internal errors are automatically detected and reported .source code is easily accessible.



“The fewer changes fewer disruptions to testing “changes to software are infrequent, controlled when they do occur, and do not invalidate existing tests. The software recovers well from failures. Changes to the software are in and can be changed when they do occur, and do not invalidate existing test. The software recovers well from failures.



“the information we have smarter we will test. “the more information the architectural design and the dependencies between internal external, shared components are well understood .the technical documentation is instantly accessible .well organized specific detailed instruction are given and accurate information is given. Changes to design communication and testers play a vital role. This is easy for testing and under stable.



The better we can control software, the more the testing can be automated and optimized.”Software and hardware states and variables can be controlled directly by the test enginer.test can be conveniently specified, automated and reproduced.



The less there is to test, the more quickly we can test it “THE program should exhibit functional simplicity (e.g. feature set is the minimum necessary to meet requirement) structural simplicity. Code simplicity (e.g. coding standard is adopted for ease of inspection and maintenance).

A simple strategic approach needed for software testing. Testing and debugging are different approaches. But testing must be accommodated in any any testing strategy.  

Testing is conducted by developer are different activities, but debugging must be independent test group. Different testing strategies are appropriate at different time. To perform testing, a software team should conduct effective formal technical reviews .by doing this many errors will be eliminated before testing commences.


Software Testing Fundamentals


Testing begins at component level and works “outward “towards the integration often entire computer based system. A strategy for software testing must accommodate low level that are necessary to verify that a small source code segment has been correctly implemented as well as high level test that validate major system functions against customer requirements


 Different strategy we can use to for successful software testing are described below.

This strategy can help for testing for tester and help easily to perform test on software in less time and accuracy in less time and less effort.

1.      State objectives explicitly

The specific objective of testing should be in measurable terms. For example effectiveness, test coverage .MTTR mean time to failure ,the cost to find band fix errors defects remaining defect density and frequency of occurrences ,test work hour per regression


2.      Develop a testing plan that emphasizes “rapid cycle testing”

The feedback generated from these rapid cycle test can be used to control quality levels and corresponding test strategies.


 3. Develop a continuous improving approach for testing progress

The test strategy should be measured .the metrics collected during testing should be used as part of a statistical process control approach for software testing.


4. Conduct formal technical reviews as a filter prior to testing

Formal technical review can uncover inconsistencies, omissions, and outright errors in the testing approach.


5.      Build robust software that is designed to it self

Software should be designed in manner that uses ant bugging techniques. That is software should be capable of diagnosing certain classes or errors in addition the design should accommodate automated testing and regression testing.


6.  Specify product requirement in a quantifiable manner long before testing commences

Although the overbidding objective of testing is to find errors, a good testing strategy also accesses other quality characteristics such as portability, maintainability, sustainability. And usability. These should be specified in a way that is way that measurable so testing results are unambiguous.


7. Understand the user of the software and develop a profile for each user category.

Use cases  and UML diagram that  help to describe the interaction scenario for each class of user can reduce overall testing effort by focusing testing on actual use of software.
