Defect Density is number of confirmed defects identified in software/module during a development period divided by the size of the software. It is calculated as defect count/size of the release, where size of release is total line of code in release.e.g. if module1 has 25 bugs, module2 has 15 bugs, and module3 has 50 bugs, …
Testing shows presence of defects – testing any software will uncover defects in it EarlyTesting is essential and will help to detect defect in the initial stage of development.Exhaustive testing is not possible – It is not possible to check each and every condition and criteria of application.Testing is context Dependent – Different domains are …

Software testing activities can be stopped based on following factors – How many Test case execution completed and bugs occurred fixed during the regression testing Based on the Testing deadline decided in test plan by project manager Mean Time between Failures (MTBF) rate if reduced and is within the acceptable rate.Code Coverage Ratio can be …

The meaning of verification is to confirm that the designed product delivers and satisfies all the functionalities expected to fulfill as expected by end user. In short it is to test whether the product build is right (functions as expected)?
The meaning of validation is to confirm if application or system designed is in compliance with the client’s requirements and its feature functions as desired and thereby meets goals and needs of end user. In short it is to verify the software build is right product.
The correct Answer is NO. All test cases need to be run, and making assumptions frequently leads to issues down the road, because as a Software quality tester it is your duty to cover all the scenarios for the application for test coverage. It may happen that in case some area of test uncovered may …
In some situations, reporting failures can be a delicate process. Perhaps a deve loper spent a lot of time on some code which does not exactly meet specifications. QA engineers need to be able to stand up for what they know is right.
Error Guessing – It is a test case design technique in which testers have to imagine the defects that might occur and write test cases to represent them.Error Seeding – It is the process of adding known bugs in a program for tracking the rate of detection & removal. It also helps to estimate the …
Software complexity – making developer difficult to understand requirement, or how to design the desiredoutput.Miscommunication between product team and customer in knowing the exact requirement.Programming errors during runtime or compile time of code base during integration process.Timeline pressure that limits unit testing of all possible scenarios on design codes or programs.Change in requirements by customer …
Defect triage is process of analyzing defect priority based on factors such as severity, risk, and time required to fix /resolve the defect. During defect triage meet, stack holders discuss and decide the priority of fixing the defects.
