Testing Basic Interview Questions

Back to Back Testing is a type of Software Testing in which two or more variants of a component are always tested with similar inputs and their corresponding outputs are compared and examine in case of any discrepancies that may exists in future. Back to Back Testing is a testing process in which events that are associated with it are defined and examined properly. This testing always involves cross-comparison of entire responses that are always obtained from functionally equivalent software components. In this testing whenever a difference is determined/observed it is measured and if essential a correction is applied too. Definition Somerville 1998 defined Back to Back Testing in his own way because he said this testing is always used when several/various versions of a system/application exist for testing. According to him in this testing all versions are tested with similar set of tests and then the results are always compared for some system/application problems...

System Testing Example  is very simple one because the name system itself gives the answer that in System Testing we have to test the complete system. In System Testing we test the both Functional as well as Non Functional parameters of Software Testing. Here I am showing you System Testing Example in a practical way and hope as a tester you did this Example every day in your company environment. Below is given the  Example of System Testing  and after seen the example definitely you do not have any issues left in your mind because example is completely relates to real world. System Testing Example – Step by Step Guide For example you are doing testing on a web application of a school and in this web application there are many modules like Teacher Module, Staff Module, Parent Module, Student Module, and Admin Module and so on. Now you have to do System Testing on a web application of a school, so your criteria for doing System Testing will be like that w...

            Alpha Testing                 Beta Testing  1. It is always performed by the developers at the software development site. 1. It is always performed by the customers at their own site. 2. Sometimes it is also performed by Independent Testing Team. 2. It is not performed by Independent Testing Team. 3. Alpha Testing is not open to the market and public 3. Beta Testing is always open to the market and public. 4. It is conducted for the software application and project. 4. It is usually conducted for software product. 5. Alpha testing is always performed in Virtual Environment. 5. Beta testing is performed in Real Time Environment. 6. It is always performed within the organization. 6. It is always performed outside the organization. 8. Alpha Testing is definitely performed and carried out at the developing organizations location with the involvement ...

Difference between QA and QC  is the heart of software testing. In software testing these two terms are majorly used in a product and project. Here I am writing the Distinction between QA (Quality Assurance) and QC (Quality Control) in tabular form so that everybody can learn it easily especially those who are new in field of Software Testing. Actually those who are new in testing field do not exactly know what is QA and QC that is the reason I am sharing with you the  Differences  in tabular form so that everybody can learn it easily whether they are new to testing field or even those who have some experienced on Testing field can also increase their knowledge by see the differences on QA and QC. Difference between QA and QC in Software Testing - Tabular Form          Quality Assurance           Quality Control 1. Quality Assurance helps us to build processes. 1. Quality ...

Developer and Tester  relation is like a relation between brother and sister like you know both brother and sister are necessary to a complete family, similarly Developer and Tester are also necessary to a complete successful project. Here I am showing you the Difference between  Developer and Tester  in a complete order so that you learn the importance of both these person. I am writing the Differences in the form of table so that all of us can learn it easily and vastly. Simple and Best Difference between Developer and Tester           Software Developer              Software Tester 1. A good developer is one who is technically sound. 1. Tester may or may not be technically sound, because we need both black box and white box testers and in black box testing programming knowledge is not necessarily must. 2. He is one who develops the ap...

Syntax Testing in Software Testing  means it is widely used software testing term. It is done in White Box Testing by using some tools or by manually depending on the nature of the project. As you know  Syntax Testing  is used in White Box Testing so it is obviously done by developers. Not in all the situations it can be done by developers, it can also be done by the testers if they are skilled testers mean white box testers. As developers are doing this testing Therefore the developers should be responsible for running a syntax check before releasing their code to QA team. In this testing,  we test the syntax of the programming languages. As syntax of the every programming languages is almost different so criteria for doing Syntax Testing is also different on these programming languages. Syntax Testing in Software Testing Example – php language Below is given the example of Syntax Testing which clears what is syntax testing? And what things we...

Why Testing is Needed  is asked by interviewer many times and on that time we just give the answer but not in proper way so interviewer get frustrated because they do not get the exact answer on  Why do we need Testing ? Here I am trying to give you the exact answer on Why Testing is Essential and simply you like the post and learn a lot from it. Why Software Testing is Necessary - Reasons Below is given some reasons which clearly show Why Software Testing is Necessary and what things we have to consider in testing. Testing is Essential because of the following reasons: 1. Testing is always needed for correctly understand the fault errors in software during its development phases. 2. It is necessary because it always ensures the users or customers satisfaction and reliability of the application. 3. It is needed in software development to increase the reliability and quality of the software. 4.  Testing is needed  to provide the variou...
