ISQI ISTQB Certified Tester Advanced Level Test Analyst (CTAL-TA v4.0) Sample Questions:

1. The following minimized decision table shows the rules for rewarding members of a hotel's loyalty scheme who have booked a room, according to the type of room (luxury or not) and/or whether they have prepaid for breakfast (yes or no). The loyalty scheme has tiers Bronze, Silver and Gold. All combinations are feasible.

Using the checksum procedure, what do you notice about the structure of the minimized table?

A) The table may have been minimized correctly
B) There are additional rules that are not shown
C) There is rule overlap, in the sense that one combination is covered by > 1 rule, or additional rules are not shown
D) The decision table is incomplete, in the sense that at least one condition value is not represented in any of the rules

2. You are working on an Agile project to develop a web-based online dating service that will allow members of the service to enter their profile, meet people who would be a good match for them, arrange social events with those people and to block people with whom they do not want contact.
Functional correctness, usability, performance and security are all important but the major concern for the stakeholders is data protection. Two environments are available for testing: the regular one is similar to the development environment, the other is a pre-production environment which is configured to become the live system when operation begins, but has currently been loaded with a representative volume of artificial profiles.
The features for member profile entry have been delivered and tested. The current iteration will deliver profile matching, which will be done on-demand in response to a request from a member to see matching profiles in their browser. The tests for these user stories' acceptance criteria will be aimed primarily at functional correctness and will be scripted. Performance testing and security testing will be done by external specialists when the functionality is stable.
The other TAs in the team are on sick leave and only have time for one exploratory test session before the end of the iteration. What is the MOST appropriate test charter in these circumstances?

A) Explore the profile matching features With the regular environment To discover any functional issues that were not covered by the story acceptance criteria
B) Explore the profile matching features With the regular test environment To discover any usability issues and security vulnerabilities
C) Explore the profile matching features With the pre-production environment To discover any functional or performance issues
D) Explore the profile entry features With the regular test environment To discover any functional issues that might affect matching

3. A simple drinks machine is described in the following state transition diagram:

How many test cases will be needed for Chow's 1-switch coverage?

A) 28
B) 40
C) 23
D) 19

4. Your project is developing an application to generate quotes for motor insurance. The calculation requires a wide range of input data and a reliable model of it has been built in a spreadsheet. There will not be enough time to get adequate functional correctness coverage from the base choice or pairwise techniques, so you have decided to do some random testing based on a probability distribution of variable values that is weighted towards their business criticality.
Which limitation of random testing should you be MOST concerned about?

A) Missing defects that are rooted in the meaning of data semantics
B) Generating tests that will exercise the same conditions repeatedly
C) Dependency on an automated test oracle to establish test results
D) The tests will focus on validation rather than verification

5. You have been appointed to be a TA in the development of a road traffic control application, which will be installed at busy road junctions to control the operation of traffic signal lights according to sensors that detect traffic volume on the various approaches to the junction. The project is still in the early stages of test planning, but it is already clear that despite a tight schedule its safety-critical nature demands careful and thorough testing.
You have been asked to decide whether automated test design would deliver benefits. Which characteristic of automated test design is MOST important for the development of this system?

A) Testware generated by tools usually contains fewer mistakes than testware created manually
B) Testware can be generated in various output formats, e.g. for use by different tools
C) Less maintenance effort for the testware after the system has gone live
D) Creating the model will expose defects in the test basis early in the project
