Interview Questions.

Q1. What Is Defect In Software Testing?

A flaw in a aspect or machine that can reason the issue or device to fail to perform its required function, e.G. An incorrect assertion or records definition. A defect, if encountered at some point of execution, might also reason a failure of the thing or gadget.

Q2. What Is Defect Management Tool?

A device that helps the recording and status monitoring of defects and changes. They frequently have workflow-oriented centers to track and manipulate the allocation, correction and re-checking out of defects and provide reporting centers.

Q3. What Is Not Reproducible Defect?

If a Defect is some time instances best appearing then that Defect is not producible defect, we need to offer evidence (pictures or database dumps) for finding it.

Q4. What Is Defect Management?

The technique of spotting, investigating, taking movement and getting rid of defects. It involves recording defects, classifying them and identifying the impact.Some businesses use Manual Process (Excel workbook), and a few corporations use Tool based system for Defect Management.

Tools Examples:Bugzilla / Issue-Tracker / PR-Tracker/Jira / Quality Center and so on...(absolutely everyone)

Q5. Explain About Defect Life Cycle?

Defect Life Cycle

Different Flows of the Defect :

New > Opened > Closed

New > Opened > Closed

New > Opened > Fixed > Re-Opened > Fixed > Closed

New > Opened > Deferred

New > Opened > Rejected > Re-Opened > Fixed > Closed Etc...

Q6. Differentiate Error, Defect, And Failure?

Terminology vary from one phase to some other in Software Application Life Cycle

Software Application Life Cycle has 3 phases;

Development phase:in Development phase if builders locate any mismatch they call it as Error or mistake

Testing section:In Testing phase if Testers discover any mismatch they name it as Defect or Bug or Fault

Production section:In Production section if Customers or End Users discover any mismatch they name it as Failure

Q7. What Is Defect Masking?

An incidence wherein one defect prevents the detection of any other.

Q8. What Is Defect Density?

The variety of defects identified in a thing or gadget divided with the aid of the size of the issue or system (expressed in general measurement terms, e.G. Lines-of code, range of classes or characteristic factors).

Q9. Give A Sample Defect Report Template?

A Sample Defect Report Template:

Defect ID: Unique No or Name

Description: Summary of the illness

Feature: Module / Function / Service , in those module TE located the illness

Test Case Name: Corresponding failing test circumstance

Reproducible (Yes / No): Yes -> Every time illness appears throughout take a look at execution

            No -> Rarely disorder appears

            If Yes, attach check method:

            If No, attach snapshot & strong motives:

Status: New / Reopen

7) Severity: Seriousness of disorder w.R.T capability (high / medium / low)

Priority: Importance of the illness w.R.T customers (high / medium / low)

Reported worm: Name of Test Engineer

Reported on: Date of submission

Assign to: Name of the accountable character in improvement crew -> PM

Build Version ID: In which build, Test Engineer fount the defect

Suggested repair (Optional): Tester tries to supply thought to clear up this illness

Fixed with the aid of: PM or Team Lead

Resolved by way of: Developer name

Resolved on: Date of fixing By Developers

Resolution kind: test out in next web page

Approved by means of: Signature of Project Manager (PM)

Note: Defect Report Template can also range from one company to some other and one mission to any other

Q10. What Is Defect Based Test Design Technique?

A manner to derive and/or choose check instances centered at one or greater illness categories, with tests being evolved from what is thought about the unique disorder category.

Q11. What Is Defect Deduction Percentage (ddp)?

The range of defects determined by a check segment, divided by way of the number found through that check section and another me afterwards.

Q12. What Is The Defect Reporting Process?

Defect Reporting Process:

Defect  Reporting Process vary from one corporation to every other.

Small scale Company:Tester -> Developer

Medium scale Company:Tester -> Test Lead -> Development Lead -> Developer

Large scale Company:Tester -> Test Lead -> DTT -> Development Lead -> Developer

Q13. What Is Reproducible Defect?

If a Defect is performing on every occasion (in every execution) then that Defect is producible defect, we will provide steps for locating it.

Q14. What Is Defect Report?

A document reporting on any flaw in a aspect or machine that could motive the issue or device to fail to carry out its required function.

Q15. What Are The Different Types Of Status Of Defects?

Status of Defects

New: Tester offers new repute whilst Reporting (for the first time)

Open: Developer / Dev lead /DTT opens the Defect

Rejected: Developer / Dev lead /DTT rejects if the defect is invalid or disorder is replica.

Fixed: Developer presents constant reputation after solving the disorder

Deferred: Developer affords this fame due to time etc...

Closed: Tester offers closed reputation after appearing confirmation Testing

Re-open: Tester Re-opens the defect with valid motives and proofs
