Severity:  How the bug impacts the application. How critical defect is and what is the impact of the defect on the whole system’s functionality. The severity is a parameter set by the tester while he opens a defect and is mainly in control of the tester. Priority:  It defines the priority in which the defects should be resolved. if there are multiple defects, the priority decides which defect has to be fixed and verified immediately versus which defect can be fixed a bit later. It is usually set by the lead Examples High Priority, Low Severity bug :-  If the company name is misspelled in the home page of the website,then the priority is high and severity is low to fix it. High Severity, Low Priority :-  Web page not found when user clicks on a link (user's does not visit that page generally) Low Priority, Low Severity :-  Any cosmetic or spelling issues which is within a paragraph or in the report High Priority, High Severity :-  An error which occurs on the basi

Load testing is a type of  performance testing .  It is a procedure which determines the performance of a system with different number of users. The load testing identifies ·          The maximum functioning capacity of an application with different users ·          Specifies whether the present infrastructure is sufficient to run the application ·          Determines the sustainability for different user loads ·          Number of concurrent users and scalability Load testing is type of non functional testing. It is mainly used for web-based applications. Why load testing is necessary?  ·          Load testing provides confidence in the system  performance  and reliability ·          It also helps to identify the bottlenecks under heavy stress conditions ·          It gives protection against poor performance with different number of users Some popular websites have experienced serious downtimes when there is heavy traffic. Some examples are: ·          an ai

  The experience based testing techniques involve the knowledge and experience of the testers and other stakeholders. They derive the test conditions by applying their knowledge in application and technologies. This  testing technique  is usually used when there is insufficient information and time in the project. The testing is done based on the skill and experience of the tester. It is also called as Ad-hoc  testing because proper specifications are not available to test the applications. Here the tester depends on the past experiences with same technologies. The tester as per his experience focuses on the important areas of the software like the areas mostly used by the customer or the areas most likely to be failed. Experience based techniques goes together with specification based and  structure or design based techniques . This technique is used for low risk system. This kind of testing is done even when there is no specifications or have inadequate specification list. Diff

  Decision table testing is one of the test design techniques for black box testing or specification based testing. The different possible input and output logical conditions are identified for testing. Software testing can be classified as white box testing and black box testing. The  test design techniques  are used for both  white box testing  and black box testing to  design the test conditions . Decision Table testing: Decision table deals with the combination of various inputs in order to produce the expected output. Basically it involves the conditions to the data while testing. For example: A customer feedback software is to be developed for a restaurant. After ordering food customers provide the rating based on two things firstly food serving time and taste of food. Whether the ordered food is served on time and whether it tastes good? The customers can choose between two different conditions and we could identify how many combinations we can make out of these two c

End to end testing is a major  type of testing  where entire software is tested from start to end.   All the functionalities within the software, their interfaces, external interfaces, interaction between the different servers & systems are tested in the environment similar to real time. End to end testing  confirms that the integrated components of the software function as expected. The entire application is tested in a real world environment like communicating with database, network, hardware and other applications. End to end testing methodology is used to test the performance of the application and whether the flow of an application is performing as designed. Generally end to end testing is phase of software testing which not only validates the software system but also checks the integration with  external interfaces . The purpose of software testing is to exercise a complete production like environment. Along with software system it also checks the batch or data processing
