Question No. 1

The following open incident report provided:

Date: 01.01.01

Description: When pressing the stop button the application status remain in "Attention" instead of "Ready'.

Severity: High

Life Cycle: Integration

Which of the following details are missing in the giving incident report?

I Identification or configuration of the application

II The name of the developer

III Recommendation of the developer

IV The actions and/or conditions that came before the pressing of the button

Show Answer Hide Answer
Correct Answer: B

In an incident report, essential details provide context and facilitate the investigation and resolution of the incident. The missing elements in the given incident report are:

I Identification or configuration of the application: This detail is crucial as it specifies which version or configuration of the application is affected, helping in reproducing the issue. IV The actions and/or conditions that came before pressing the button: Understanding the sequence of actions leading to the issue is vital for replicating and diagnosing the problem.

The name of the developer (II) and the recommendation of the developer (III) are not typically included in an incident report as they do not contribute to identifying or resolving the incident. The focus is on the incident's details, reproduction steps, and the system's state rather than on personnel or proposed solutions at this stage. Therefore, option B, which includes both I and IV, is the correct answer.


Question No. 3

Which of the following statements is TRUE'?

Show Answer Hide Answer
Correct Answer: D

Statement D is correct. According to the ISTQB CTFL syllabus, both black-box test techniques (which focus on testing without internal knowledge of the application) and experience-based test techniques (which rely on testers' experience and intuition) can be applied to both functional and non-functional testing. Functional testing is concerned with what the system does, whereas non-functional testing looks at how the system performs under certain conditions. These techniques are versatile and can be employed to address both these aspects.


Question No. 4

A mid-size software product development company has analyzed data related to defects detected in its product and found out that detects fixed in earlier builds are getting re-opened after a few months.

The company management now seeks your advice in order to reverse this trend and prevent re-opening of defects fixed earlier.

What would be your FIRST recommendation to the company?

Show Answer Hide Answer
Correct Answer: B

Regression testing is a type of testing that verifies that previously tested software still performs correctly after changes. Regression testing can help prevent re-opening of defects fixed earlier by ensuring that they do not cause any new failures or side effects. The first recommendation to the company is to verify existing regression test suite are adequate, and augment it, if required, in order to ensure that defects fixed earlier get re-tested in each subsequent build. This can help improve the coverage and effectiveness of regression testing and detect any regression defects as soon as possible. Automating existing test suites may also help reduce the time and effort required for regression testing, but this is not the first recommendation, as automation may not be feasible or cost-effective for all test cases. Analyzing the product modules containing maximum defects and getting them thoroughly tested and defects fixed as a one-time activity may also help reduce the defect density and improve the quality of those modules, but this is not the first recommendation, as it does not address the root cause of re-opening defects fixed earlier. Training or replacing the teams responsible for development and testing of the modules containing maximum number of defects may also help improve their skills or performance, but this is not the first recommendation, as it may not be necessary or appropriate for all teams.

Question No. 5

Which of the following is a typical potential risk of using test automation tools?

Show Answer Hide Answer
Correct Answer: D

One of the common risks associated with test automation tools is the underestimation of the effort required to maintain test scripts. Test scripts can become outdated or broken due to changes in the application, requiring significant effort to update and maintain them. This risk is highlighted in the ISTQB CTFL syllabus under the discussion of the benefits and risks of test automation.
