Can you explain a bug life cycle?
Defect life cycle, also known as Bug Life cycle is the journey of a defect cycle, which a defect goes through during its lifetime. It varies from organization to organization and also from project to project as it is governed by the software testing process and also depends upon the tools used.
What is bug life cycle with example?
A Defect life cycle, also known as a Bug life cycle, is a cycle of a defect from which it goes through covering the different states in its entire life. This starts as soon as any new defect is found by a tester and comes to an end when a tester closes that defect assuring that it won’t get reproduced again.
What are the challenges in testing?
Manual and Automation Testing Challenges
- Software Testing has a lot of challenges both in a Manual as well as in Automation.
- This is not the case always.
- #1) Testing the complete application.
- #2) Misunderstanding of company processes.
- #3) Relationship with Developers.
- #4) Regression Testing.
- #5) Lack of Skilled Testers.
- #6) Testing always under Time Constraint.

The biggest software testing challenges
- Communication issues.
- Impossibility of complete testing.
- Lack of requirements documentation.
- Unstable environment.
What are the 3 types of test data?
Test data commonly include the following types
- Valid test data. It is necessary to verify whether the system functions are in compliance with the requirements, and the system processes and stores the data as intended.
- Invalid test data.
- Boundary test data.
- Wrong data.
- Absent data.
What is the defect liability period?
A defects liability period is a set period of time after a construction project has been completed during which a contractor has the right to return to the site to remedy defects. A typical defects liability period lasts for 12 months.
What are the categories of defects?
3 Types of defects every importer needs to know. Quality control professionals typically classify quality defects into three main categories: minor, major and critical. The nature and severity of a defect determines in which of the three categories it belongs.
Who gave the concept of defect?
Zero Defects, a term coined by Mr. Philip Crosby in his book “Absolutes of Quality Management” has emerged as a popular and highly-regarded concept in quality management – so much so that Six Sigma is adopting it as one of its major theories.
What is correct software process cycle?
plan , do , check,act is the correct form of software process cycle.
What is difference between bug and defect?
“A mistake in coding is called Error, error found by tester is called Defect, defect accepted by development team then it is called Bug, build does not meet the requirements then it Is Failure.” In other words Defect is the difference between expected and actual result in the context of testing.
What are the valid causes of defects?
Here are a few of the most common reasons defects in products happen.
- Poor design.
- Lack of testing.
- Lack of danger warnings.
- Poor installation instructions.
- Improper maintenance of the individual components.
- Assembly or construction error.
- Delivery damage.
What are the major challenges of test data management?
Major Test Data Management challenges faced by modern businesses
- Shortage of data for testing. Testing with real-time data is dangerous, and certainly against data privacy regulations.
- Vulnerability of test data. Most testing projects fail because of poor data quality.
- Safe storage of test data.
- Inaccuracy in performance.
What is defect in quality control?
A defect is a type of nonconformity. It occurs when a product fails to meet specified or intended use requirements. A defective is a unit of product which contains one or more defects. Failure to meet requirements for quality characteristics are usually described in terms of defects or defectives.
What is a defect log?
Defect logging, a process of finding defects in the application under test or product by testing or recording feedback from customers and making new versions of the product that fix the defects or the clients feedback.
What is STLC life cycle?
STLC stands for Software Testing Life Cycle. STLC is a sequence of different activities performed by the testing team to ensure the quality of the software or the product. As soon as the development phase is over, the testers are ready with test cases and start with execution.
How do you classify software defects?
Three common classifications of software bugs
- Functional defects. Functional defects are the errors identified in case the behavior of software is not compliant with the functional requirements.
- Performance defects.
- Usability defects.
- Compatibility defects.
- Security defects.
How do you identify defects?
Techniques to find defects can be divided into three categories:
- Static techniques: Testing that is done without physically executing a program or system.
- Dynamic techniques: Testing in which system components are physically executed to identify defects.
What is normal test data?
Normal data is test data that is typical (expected) and should be accepted by the system.
What are chemical defects?
A point defect can be an atom missing from a site in the crystal (a vacancy) or an impurity atom that occupies either a normal lattice site (a substitutional impurity) or a hole in the lattice between atoms (an interstitial impurity). A Frenkel defect is an ion that occupies an incorrect site in the lattice.
What are the 7 phases of STLC?
The steps within the STLC are six systematic approaches: requirement analysis, test planning, test case development, environment setup, test execution and test cycle closure.
What are three types of product defects?
Though there are numerous instances in which a defective product could injure a person, defects that give rise to supplier, seller, or manufacturer liability are categorized by three types of product defects: design defects, manufacturing defects, and marketing defects.
What is defect example?
The definition of a defect is an imperfection or lacking that causes the person or thing with the defect to fall short of perfection. An example of a defect is a genetic condition that causes weakness or death. An example of a defect is faulty wiring that results in a product not working. noun.
How do you define a defect?
A defect is a physical, functional, or aesthetic attribute of a product or service that exhibits that the product or service failed to meet one of the desired specifications.
When should we stop testing?
Many modern software applications are so complex and run in such an Interdependent environment, that complete testing can never be done. 2) Stop the Testing when the test cases have been completed with some prescribed pass percentage. 3) Stop the Testing when the testing budget comes to its end.
What is STLC and SDLC?
Software Development Life Cycle (SDLC) is a sequence of different activities performed during the software development process. Software Testing Life Cycle (STLC) is a sequence of different activities performed during the software testing process.
What are the steps in the bug cycle?
Defect/Bug Life Cycle in Software Testing
- New: When a new defect is logged and posted for the first time.
- Assigned: Once the bug is posted by the tester, the lead of the tester approves the bug and assigns the bug to the developer team.
- Open: The developer starts analyzing and works on the defect fix.
What is defect injection?
Defect injection — Deliberately inserted defects, inserted at any phase, and intended to determine the effectiveness of quality assurance, testing, or defect containment discipline. Also known as “defect seeding”.
What is meant by regression testing?
Definition: Regression testing refers to a type of software testing that is used to verify any modification or update in a software without affecting the overall working functionality of the said software. In case regression testing brings up critical issues, then in most cases, functionality testing is halted.
What is defect and types of defect?
Defects are defined as the deviation of the actual and expected result of system or software application. Defects can also be defined as any deviation or irregularity from the specifications mentioned in the product functional specification document. Defects are caused by the developer in development phase of software.
How do you ensure test coverage?
