iSQI CTFL_Syll2018 Exam - Topic 6 Question 121 Discussion

Posted by Davida on Mar 07, 2026 at 10:56 AM

What type of test design technique is the most effective in testing screen-dialog flows?

Suggested Answer: A

Screen-dialog flows are sequences of screens and dialogs that represent the user interface and interaction of a system.Use case testing is a technique that uses use cases as a test basis to derive test cases1.A use case is a description of interactions between actors and a system to achieve a goal1. Use case testing is the most effective technique in testing screen-dialog flows, as it can capture the user requirements, scenarios, and expected outcomes of the system.Boundary value testing is a technique that uses boundary values as a test basis to derive test cases1.A boundary value is an input value or output value on the edge of an equivalence partition or at the smallest or largest value of a range1. Boundary value testing is not the most effective technique in testing screen-dialog flows, as it is more suitable for testing numerical inputs and outputs.Statement testing and coverage is a technique that uses statements in the source code as a test basis to measure the coverage achieved by a test suite1.A statement is a minimal executable unit of source code1. Statement testing and coverage is not the most effective technique in testing screen-dialog flows, as it is more suitable for testing the internal logic and structure of the code.State transition testing is a technique that uses state transition diagrams as a test basis to derive test cases1.A state transition diagram shows the states of a system and the transitions between them triggered by events or conditions1. State transition testing is not the most effective technique in testing screen-dialog flows, as it is more suitable for testing systems that have complex or dynamic behavior based on different states.

B is too limited for this type of testing.

A could work too, but it’s not as thorough as D.
WI

I agree, D makes sense for screen-dialog flows.

I think D is the best choice. It covers all possible states.

B is useful, but not for screen-dialog flows specifically.
AS

A could work too, but it’s more about scenarios.

I agree! State transition testing is crucial for flows.

Surprised that state transition is the top choice, I thought it was more niche!
HO

Use case testing gives a good overview, but not as detailed.
PE

Wait, isn't boundary value testing also important for user inputs?
AL
Alecia 6 months ago
Totally agree, it captures all the possible states!
MA
Marti 6 months ago
I think state transition testing is key for screen flows.
MI
Mi 6 months ago
Use case testing gives a broader view, though!
WI
Willard 6 months ago
Not sure about that, seems too specific for general flows.
LA
Lavonna 6 months ago
Wait, isn't boundary value testing also important?
MA
Margot 6 months ago
Totally agree, it captures all the user interactions!
SI
Simona 7 months ago
I think state transition testing is key for screen flows.
CH
Chun 7 months ago
I practiced a question similar to this, and I think statement testing is more about code coverage, not really about flows.
KA
Kaitlyn 7 months ago
I feel like boundary value testing is more about input limits rather than screen flows, so I’m leaning towards something else.
DO
Donte 7 months ago
I'm not entirely sure, but I remember use case testing being mentioned in relation to user interactions.
TE
Tegan 7 months ago
I think state transition testing might be the right choice since it focuses on how the system behaves with different inputs.
