What are the contents in an effective Bug report?
Project, Subject, Description, Summary, Detected By (Name of the Tester), Assigned To (Name of the Developer who is supposed to the Bug), Test Lead ( Name ), Detected in Version, Closed in Version, Date Detected, Expected Date of Closure, Actual Date of Closure, Priority (Medium, Low, High, Urgent), Severity (Ranges from 1 to 5), Status, Bug ID, Attachment, Test Case Failed (Test case that is failed for the Bug)
What is Bug Life Cycle?
Bug Life Cycle is nothing but the various phases a Bug undergoes after it is raised or reported.
New or Opened
Assigned
Fixed
Tested
Closed


What is Error guessing and Error seeding ?
Error Guessing is a test case design technique where the tester has to guess what faults might occur and to design the tests to represent them.
Error Seeding is the process of adding known faults intentionally in a program for the reason of monitoring the rate of detection & removal and also to estimate the number of faults remaining in the program.
What is the difference between Bug, Error and Defect?
Error : It is the Deviation from actual and the expected value.
Bug : It is found in the development environment before the product is shipped to the respective customer. Defect : It is found in the product itself after it is shipped to the respective customer.
What are SDLC and STLC ? Explain its different phases.
SDLC
Requirement phase
Designing phase (HLD, DLD (Program spec))
Coding
Testing
Release
Maintenance
STLC
System Study
Test planning
Writing Test case or scripts
Review the test case
Executing test case
Bug tracking
Report the defect
What is Ad-hoc testing?
Ad hoc testing is concern with the Application Testing without following any rules or test cases.
For Ad hoc testing one should have strong knowledge about the Application.
