NEW QUESTION # 323
If a developer is analyzing a failure to determine the cause, he is engaging in what type of activity?
Answer: C
NEW QUESTION # 324
Which one of the following statements correctly describes the term 'debugging'?
Answer: B
Explanation:
Debugging is the development activity that finds, analyses and fixes defects. Unlike testing, which aims to identify defects in the software, debugging is the process that developers use to locate and correct the errors found during testing. This involves diagnosing the root causes of these defects and making necessary code changes to resolve them. Debugging is a critical part of the development cycle and ensures that the software functions correctly after defects are fixed.
NEW QUESTION # 325
Scenario 2 "Big Drop":
The management of the company "The Big Drop" has instructed the Product Team to configure the discounts in the sales terminals so that frequent customers receive an additional discount on top of a bulk discount, based on the following table:
You must design test cases to represent all POSSIBLE and REAL business scenarios. Test cases should be generated using the input data provided in the table above.
How many POSSIBLE decision rules can be extracted from the table above?
Answer: D
Explanation:
This is a classic application of the Decision Table Testing technique.
We are combining two conditions:
Purchase Volume, which has3 equivalence classes:
1 to 100 units 0%
101 to 1000 units 5%
More than 1000 units 10%
Customer Type, which has2 categories:
Frequent Customer = YES 5% extra
Frequent Customer = NO 0%
This gives:
3 (bulk discount levels) - 2 (frequent customer options) = 6 unique decision rules Each combination of these input conditions defines a separate test scenario with its own outcome.
"Decision table testing is used to identify the different combinations of inputs and their associated outputs. Each unique combination of input values defines a rule."
NEW QUESTION # 326
Which of the following answers describes a reason for adopting experience-based testing techniques?
Answer: A
Explanation:
Experience-based testing techniques are adopted for several reasons, most importantly because they can identify defects that might be missed by more systematic approaches like black-box and white-box testing.
While systematic techniques follow predefined procedures and cover specific criteria, experience-based techniques leverage the tester's knowledge, intuition, and experience, which can be especially effective in uncovering subtle and complex issues.
Experience-based testing techniques include methods such as error guessing and exploratory testing. These methods rely on the tester's background and intuition to predict where defects might be located and how the system might fail. These techniques are particularly useful in situations where the requirements and specifications are incomplete or ambiguous, and where creative and ad-hoc approaches can provide significant value.
References:
* The official ISTQB CTFL syllabus emphasizes that experience-based techniques can find defects that more systematic techniques might miss, which makes them valuable complements to other testing methods.
NEW QUESTION # 327
Consider an estimation session where a six-member Agile team (Memb1, ... , Memb6) is performing a planning poker session to estimate a user story (in story points). Team members are using a set of cards with the following values: 1, 2, 3, 5, 8, 13, 21. Below is the outcome produced by the first round of estimation for this session:
Which of the following answers best describes how the estimation session should proceed?
Answer: D
Explanation:
In Agile estimation sessions, particularly during Planning Poker, the goal is to reach a consensus on the effort required for a user story. The process encourages discussion and collaboration among team members to understand the story's requirements and complexities fully. Here's a breakdown of the options and why D is the correct choice:
Option A:Calculating the arithmetic mean of all estimates.
* This method is straightforward but does not facilitate team discussion or consensus-building. It merely averages out the estimates without addressing the reasons behind the varying estimates. Thus, important insights and understanding of the task complexity might be missed.
Option B:Selecting the most frequent estimate value.
* While this approach acknowledges the majority's opinion, it ignores the minority views, which might highlight significant aspects of the story that need consideration. It doesn't ensure that all perspectives are considered and discussed.
Option C:Calculating the mean of the most optimistic and pessimistic estimates.
* This approach considers the extremes but again lacks the team discussion and consensus aspect. It also assumes that the extreme values alone can balance out the estimate, which might not always capture the true complexity or simplicity of the task.
Option D:Discussing the most pessimistic and optimistic estimates.
* This approach fosters team collaboration and understanding. Memb4 and Memb6 explain their reasoning for the highest and lowest estimates, respectively, which can reveal different perspectives on the task's complexity. This discussion helps the team align their understanding and often leads to a more accurate and agreed-upon estimate in subsequent rounds.
In conclusion, the main goal of Agile estimation techniques like Planning Poker is to encourage team communication and collaboration to ensure that all aspects of the user story are considered. Option D best aligns with this goal by promoting discussion and consensus.
