Bug tracking is the process of identifying, reporting, prioritizing, and resolving software defects.

• Bugs are identified through testing or user feedback

• Bugs are reported in a bug tracking tool with details like steps to reproduce, severity, and priority

• Bugs are prioritized based on their impact and severity

• Bugs are assigned to developers for resolution

• Developers fix the bugs and mark them as resolved

• Testers verify the fix and mark the bug as closed or reopen if the issue pers...read more

STLC stands for Software Testing Life Cycle. It is a process followed to ensure quality in software development.

• STLC consists of several phases including requirement analysis, test planning, test case development, test execution, and test closure.

• Requirement analysis involves understanding the software requirements and identifying test scenarios.

• Test planning involves creating a test plan, test strategy, and test estimation.

• Test case development involves creating test cases b...read more

Regression testing is testing the entire system after making changes while retesting is testing the specific area where a defect was fixed.

• Regression testing ensures that changes made to the system do not have any unintended consequences on the existing functionality.

• Retesting is done to ensure that a defect has been fixed and does not reoccur.

• Regression testing is done after every major change in the system while retesting is done after every defect fix.

• Regression testing is...read more

Software testing is the process of evaluating a software application or system to find defects or errors.

• It involves executing the software with the intention of finding bugs or issues

• It ensures that the software meets the specified requirements and works as expected

• It can be done manually or with the help of automated tools

• It includes functional testing, performance testing, security testing, and more

• It is an important part of the software development life cycle

Functional testing is a type of testing that verifies if the software meets the specified requirements and performs its intended functions.

• It focuses on the external behavior of the software

• It is performed based on the functional specifications

• It involves black box testing techniques

• It ensures that the software is working as expected

• Examples include testing of login functionality, search functionality, etc.
