What is Bug?
A bug is a problem or error in the software that causes it to behave in an unexpected or unintended way. It is often caused by a mistake or oversight during the software development process. Bugs can occur due to various reasons, such as incorrect logic, incorrect syntax, or unexpected user input. For example, a button on a web page that does not work when clicked can be considered a bug.
Defects in Software Testing
A defect is a deviation from the software requirements or specifications. It is a flaw in the software that causes it to fail to meet the functional or non-functional requirements. Defects can occur due to various reasons, such as incomplete or incorrect requirements, design flaws, or coding errors. For example, if a software application is designed to sort data in a specific order, but fails to do so, it can be considered a defect.
Bug Report in Software Testing
A bug report is a document that is created by testers or users to report a problem or issue in the software. The purpose of a bug report is to provide information about the problem so that it can be identified and resolved by the developers.
A well-written bug report provides clear and concise information about the problem, which makes it easier for the developers to understand and resolve the issue. While reporting the bug, your Bug Report should contain the following information
Defect_ID - Unique identification number for the defect.
Defect Description - Detailed description of the Defect including information about the module in which the defect was found.
Version - Version of the application in which the defect was found.
Steps - Detailed steps along with screenshots with which the developer can reproduce the defects.
Date Raised - Date when the defect is raised
Reference- where in you Provide reference to the documents like. requirements, design, architecture or maybe even screenshots of the error to help understand the defect
Detected By - Name/ID of the tester who raised the defect
Status - Status of the defect, more on this later
Fixed by - Name/ID of the developer who fixed it
Date Closed - Date when the defect is closed
Severity which describes the impact of the defect on the application
Priority is related to defect fixing urgency. Severity Priority could be High/Medium/Low based on the impact urgency at which the defect should be fixed respectively
What is Defect Management Process?
Defect management is the process of identifying, tracking, prioritizing, and resolving defects in software. It is a continuous process that begins with the identification of defects and continues until the defects are resolved. The defect management process involves the following steps:
Defect identification is the first step in the defect management process. Defects can be identified through various means, such as manual testing, automated testing, or user feedback. The identification of defects is important to ensure that they are captured early in the software development life cycle, which makes it easier to resolve them.
Once a defect is identified, it is important to log the defect in a defect tracking system. The defect tracking system helps to capture all the details related to the defect, such as the defect description, severity, priority, steps to reproduce, and the person who identified the defect. Defect logging is important to ensure that all defects are tracked and managed effectively.
Defect triage is the process of reviewing and prioritizing defects based on their severity and impact on the system. The severity of a defect is determined by its impact on the system, while the priority of a defect is determined by its urgency and importance. Defect triage is important to ensure that the most critical defects are addressed first.
Defect resolution is the process of fixing the defect. Once a defect is identified, logged, and triaged, it is assigned to a developer who is responsible for resolving the defect. The developer analyzes the defect and identifies the root cause, and then fixes the defect by modifying the code or system configuration. Once the defect is fixed, the developer tests the fix to ensure that it has resolved the issue.
Defect verification is the process of ensuring that the defect has been resolved successfully. The verification process involves retesting the system to ensure that the defect has been fixed and that the system is functioning as expected. Defect verification is important to ensure that the defect has been resolved completely.
Defect closure is the final step in the defect management process. Once the defect has been verified and resolved, it is closed in the defect tracking system. The defect closure process involves updating the defect status, closing the defect, and documenting the resolution. Defect closure is important to ensure that all defects are tracked and managed effectively.
Benefits of Defect Management:
Effective defect management provides several benefits, including:
Improved software quality: Defect management helps to ensure that all defects are identified, tracked, and resolved, which improves the overall quality of the software.
Reduced development time and cost: Defect management helps to identify defects early in the software development life cycle, which reduces the time and cost of fixing defects.
Increased customer satisfaction: Defect management helps to ensure that the software is delivered with the highest level of quality, which increases customer satisfaction.
Improved team productivity: Defect management helps to improve team productivity by providing a systematic approach to defect identification, tracking, and resolution.
Defect management is an essential aspect of software testing and plays a critical role in ensuring that software is delivered with the highest level of quality and functionality. The defect management process involves several steps, including defect identification, logging, triage, resolution,
