- Mention some examples of Bug Severity and Bug Priority?
High Priority & High Severity: Submit button is not working on a login page and customers are unable to login to the application
Low Priority & High Severity: Crash in some functionality which is going to deliver after couple of releases
High Priority & Low Severity: Spelling mistake of a company name on the homepage
Low Priority & Low Severity: FAQ page takes a long time to load
- What is a Critical Bug?
A critical bug is a show stopper which means a large piece of functionality or major system component is completely broken and there is no workaround to move further.
For example, Due to a bug in one module, we cannot test the other modules because that blocker bug has blocked other modules. Bugs which affects the customers business are considered as critical.
- “Sign In” button is not working on Gmail App and Gmail users are blocked to login to their accounts.
- An error message pops up when a customer clicks on transfer money button in a Banking website.
- What is the difference between a Standalone application, Client-Server application and Web application?
Standalone applications follow one-tier architecture. Presentation, Business, and Database layer are in one system for a single user.
Client-server applications follow two-tier architecture. Presentation and Business layer are in a client system and Database layer on another server. It works majorly in Intranet.
Web server applications follow three-tier or n-tier architecture. The presentation layer is in a client system, a Business layer is in an application server and Database layer is in a Database server. It works both in Intranet and Internet.
- What is Bug Life Cycle?
Bug life cycle is also known as Defect life cycle. In Software Development process, the bug has a life cycle. The bug should go through the life cycle to be closed. Bug life cycle varies depends upon the tools (QC, JIRA etc.,) used and the process followed in the organization.
- What is Bug Leakage?
A bug which is actually missed by the testing team while testing and the build was released to the Production. If now that bug (which was missed by the testing team) was found by the end user or customer then we call it as Bug Leakage.
- What is Bug Release?
Releasing the software to the Production with the known bugs then we call it as Bug Release. These known bugs should be included in the release note.
- What is Defect Age?
Defect age can be defined as the time interval between date of defect detection and date of defect closure.
Defect Age = Date of defect closure – Date of defect detection
Assume, a tester found a bug and reported it on 1 Jan 2016 and it was successfully fixed on 5 Jan 2016. So the defect age is 5 days.
- What is Error Seeding?
Error seeding is a process of adding known errors intendedly in a program to identify the rate of error detection. It helps in the process of estimating the tester skills of finding bugs and also to know the ability of the application (how well the application is working when it has errors.
