Today, weβll dive into the Defect Life Cycle. Can anyone tell me what they think defines a defect's life cycle?
Is it about how a defect moves from being found to being fixed?
Exactly! The defect life cycle consists of several stages: New, Open, Assigned, Fixed, Retest, and Closed. Think of an acronym like 'N-O-A-F-R-C' to remember these stages: New, Open, Assigned, Fixed, Retest, Closed. Can anyone explain what happens in the 'Retest' stage?
Isn't that when we check if the defect has been successfully fixed?
Yes! The Retest stage is vital for confirming the fix. Remember this cycle as it will aid your test management processes. It's crucial for understanding how to track and manage defects effectively.
Severity vs. Priority in Defect Reporting

Now letβs consider Severity and Priority. What do these terms mean to you?
Is Severity about how serious a defect is, and Priority is about how soon it needs fixing?
Correct! Severity relates to the impact of a defect, such as Critical or Minor, while Priority refers to the urgency of fixing it, like High or Low. Letβs think about a practical example: a crash is High Severity and High Priority, whereas a typo might be Low Severity but could still be High Priority if it affects a major launch. Can anyone think of an example where a low-severity defect might be high priority?
Maybe if itβs in a public-facing website on the launch day?
Exactly! Remember the phrase 'Severity is the Pain, Priority is the Gain' to help you differentiate these concepts. Understanding this distinction is key in prioritizing your testing efforts.
Test Plan Creation

Next, weβll look at Test Plan Creation. What elements do you think are important in a test plan?
Maybe the testing objectives and what features to test?
Yes! A solid test plan includes scope, objectives, resources, schedule, and risks. For instance, when outlining the scope, you might specify testing for login and checkout features. Letβs work on creating a test plan for a mobile app, focusing on key elements. Remember: Good planning leads to successful testing!
How do we identify the risks to include in the test plan?
Great question! You can identify risks by assessing potential issues that could affect testing outcomes, such as resource availability or complex features. A common acronym for risks is 'P-R-A-I-R' - People, Resources, Application complexity, Integration points, and Requirements clarity.
Hands-on with Test Case Templates & Bug Reporting

Finally, letβs get practical. Youβll create test cases and bug reports using templates. Why do you think templates are useful?
They help keep things consistent and organized.
Exactly! Templates provide a structure that aids clarity. Now, I want you to write two test cases using a standard format, including IDs, descriptions, steps, and expected results. This will help you practice effective documentation.
Can we also practice writing a bug report after this?
Yes, absolutely! Follow the standard structure for a bug report: ID, summary, steps to reproduce, actual versus expected results. Itβs essential for effective communication between testers and developers.
Simulating Testing Scenarios

In our last session of the week, weβll simulate a testing scenario where you'll log defects and update a test plan. How do you think this will help your testing skills?
It will make us more prepared for actual testing environments.
Exactly! Real-world simulations help bridge theory and practice. Start by executing three test cases, and log at least one defect you encounter. Remember to reflect on what changes to the test plan might be necessary based on your findings. What could be a crucial metric to track during this process?
The defect density might be important!
Right! Defect density helps quantify the defects found relative to the size of the test. Letβs ensure you all make notes on insights gained during this exercise.

Quick Overview
Standard
In Week 3, students delve into critical aspects of defect management, learning about the stages of the defect life cycle from identification to closure. The distinction between severity and priority in defect reporting is emphasized, alongside practical exercises like test plan creation and bug reporting. Hands-on activities reinforce theoretical knowledge with real-world application.
Detailed
Detailed Summary
In this section, learners explore the Defect Life Cycle, detailing its key stages: New, Open, Assigned, Fixed, Retest, and Closed. Understanding this life cycle is crucial, as it impacts how defects are handled throughout the testing process. For instance, a newly identified bug progresses through various stages, moving from evaluation to resolution.
Additionally, learners differentiate between Severity and Priority when reporting defects. Severity reflects the impact of a defect on the system, while priority indicates the urgency for fixing it. For example, a critical application failure may have high severity but low priority if it's isolated to an infrequently used feature.
Following the discussion on defects, students engage in Test Plan Creation. A test plan outlines the scope, objectives, resources required, risks, and deliverables, ensuring a systematic approach to testing. Practical exercises reinforce this knowledge by guiding students to create a test plan for a mobile app, as well as using templates for test cases and bug reports.
The week culminates in hands-on simulations where students execute test cases and log defects, facilitating a practical understanding of test management processes.

Chapter Content
The defect life cycle includes: New, Open, Assigned, Fixed, Retest, Closed.
Example: A bug (login failure) is marked βNew,β assigned to a developer, fixed, retested, and closed.
Detailed Explanation
The defect life cycle is a crucial part of quality assurance. Every defect (or bug) follows a defined path from discovery to resolution. It starts as 'New' when identified, indicating it's yet to be addressed. Once prioritized, it moves to 'Open,' meaning it is now on the team's radar. After assignment to a developer, it is worked on until it is 'Fixed.' Once fixed, it enters the 'Retest' phase where QA verifies the fix is successful. If the defect is resolved, it moves to 'Closed.' Understanding and managing this life cycle helps ensure that all bugs are systematically tracked and resolved.
Examples & Analogies
Think of the defect life cycle like a patient in a hospital. When a patient arrives with a health issue (New), they are triaged (Open), seen by a doctor (Assigned), treated (Fixed), and then checked during follow-up visits (Retest) to ensure they are fully healthy (Closed). Each step is critical for determining successful recovery, just as each step in the defect life cycle is essential for achieving software quality.
Severity vs. Priority in Defect Reporting

Chapter Content
β’ Severity: Impact of the defect (e.g., Critical, Minor).
β’ Priority: Urgency of fixing (e.g., High, Low).
Example: A crash (High Severity, High Priority) vs. a typo (Low Severity, Low Priority).
Detailed Explanation
In defect reporting, understanding the difference between severity and priority is crucial. Severity refers to how serious a defect is in terms of its impact on the application. For example, a defect that causes a system crash is considered 'high severity.' In contrast, priority indicates how soon the defect should be fixed; a high-priority defect needs immediate attention, while a low-priority defect can be addressed later. This distinction helps teams allocate resources effectively and address the most critical issues first.
Examples & Analogies
Imagine you find a small typo in a marketing email (low severity) and a broken payment gateway on a site (high severity). You might prioritize fixing the payment gateway quickly (high priority), as it directly impacts sales. The typo, while not ideal, can wait until later to be corrected because it doesnβt prevent the main functions of the email.

Chapter Content
A test plan includes scope, objectives, resources, schedule, and deliverables.
Example Test Plan Section:
Scope: Test login, registration, and checkout features.
Objectives: Ensure 100% functional coverage.
Resources: 2 QAs, TestRail, Chrome browser.
Detailed Explanation
A test plan is a document that outlines the strategy for testing software. It defines the scope, explaining what features will be tested, and the objectives, establishing what the testing aims to achieve. Additionally, it identifies the resources needed, such as personnel and tools, and details the schedule for when these tests will take place. Clear test plans help ensure that testing is structured and complete, allowing for effective management of QA processes.
Examples & Analogies
Think of a test plan like a blueprint for a building. Just as a blueprint includes dimensions, room assignments, and what materials to use, a test plan lays out the scope of testing, specifies objectives, outlines required resources, and schedules activities, ensuring that every aspect of the software is thoroughly tested before launch.

Chapter Content
Students use templates to write test cases and bug reports.
Detailed Explanation
Utilizing templates for test cases and bug reports standardizes the QA process, making it easier to create consistent and clear documentation. A test case template typically includes sections such as ID, Description, Steps, and Expected Result, which guide testers in writing comprehensive test scenarios. Similarly, a bug report template helps in documenting defects with clear fields for identification, steps to reproduce, and additional comments, aiding in effective communication between QA and development teams.
Examples & Analogies
Consider a recipe for baking a cake. Just like the recipe outlines the ingredients and steps needed for consistent results, test case templates provide a structured format for writing tests, ensuring that all necessary components are included, which, in turn, leads to reliable outcomes in quality assurance.

Detailed Explanation
Simulating testing scenarios allows students to apply their learning in a real-world context, practicing the entire process of executing tests, identifying bugs, and updating respective documentation like test plans. This hands-on practice fosters a deeper understanding of how testing operates in practice, highlighting the importance of attention to detail and communication throughout the QA process.
Examples & Analogies
Picture a rehearsal for a theater production. Actors go through their lines and blocking to find any issuesβjust like testers execute test cases to identify bugs. After rehearsals, they fine-tune their performances based on what they learned, similar to how QA updates test plans or documentation based on testing results. This cycle of practice, evaluation, and adjustment is key to ensuring a successful final performance or software release.
