ISQI ISTQB Certified Tester Foundation Level (CTFL) v4.0 Sample Questions:

1. Consider an estimation session in which a six-member Agile team (Memb1..... Memb6) uses the planning poker technique to estimate a user story (in story points). The team members will use a set of cards with the following values: 1,2, 3,5, 8,13,21. Below is the outcome of the first round of estimation for this session:

Which of the following answers BEST describes how the estimation session should proceed?

A) The final estimate of the user story in story points is determined by calculating the average value between the most optimistic estimate of 21 story points (Memb4> and the most pessimistic estimate of 1 story point (Memb6)
B) Further estimation rounds should be performed until all team members will pick the card having the same value: this value will represent the final estimate of the user story in story points.
C) The final estimate of the user story in story points is determined by applying the three-point estimation technique with the following input values most optimistic estimate - 1, most likely estimate - 3, and most pessimistic estimate - 21
D) Memb6 and Memb4 which have produced the most pessimistic and the most optimistic estimates respectively, should explain the reasons of their choices to stimulate a discussion between all members before proceeding to another estimation round

2. Which of the following should you review using static testing?

A) Memory leak during execution
B) Interactive output from a debugger
C) Performance of a module under load
D) Test plan

3. Which of the following is an example of a test-first approach to development?

A) Tests are written first, then the code is written to satisfy the tests
B) Focus on delivering small, client-valued features through iterative cycles
C) Software development and IT operations are combined to enable faster delivery
D) Focus on monitoring software in production to fix issues after release quickly

4. Confirmation testing is performed after:

A) the execution of an automated regression test suite to confirm the absence of false positives in the test results
B) a defect is fixed and after other tests do not find any side-effect introduced in the software as a result of such fix
C) a failed test, and aims to run that test again to confirm that the same behavior still occurs and thus appears to be reproducible
D) a defect is fixed, and if such testing is successful then the regression tests that are relevant for such fix can be executed

5. Scenario "Happy Tomatoes"
An intelligent application for agricultural use incorporates temperature sensors located at different points of an enclosure. The sensors measure and record the temperature at regular intervals and extract the statistical values for these measurements. These values include the average daily temperature.
A new variety of tomatoes is currently being grown and the"World Organization for Happy Tomatoes"has established temperature ranges related to vegetative development.
When the system establishes that the average temperature is within a specific range, it emits a value that will be used to monitor and control the crop.

Using the equivalence partitioning technique, identify the set of input values that provides the HIGHEST coverage.

A) {8,10,25,40}
B) {7,10,21,40}
C) {7,10,25,40}
D) {7,10,25,29}
