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

Question 1

In which of the following circumstances is the transition from a high-level test case to a low-level test case MOST LIKELY to be deferred from test design to test implementation?

A. When product risk analysis has not been completed
B. When specific test data are needed for the test case
C. When the person who runs the test will not be its author
D. When the details required depend on the test execution schedule

Question 2

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

Question 3

You are 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. This safety-critical project is still in the early stages of test planning and the project schedule is tight.
The Test Manager has asked you if crowd testing should be included in the project's test strategy. You do NOT think it should. Which limitation of crowd testing MOST influences your view?

A. Ensuring comprehensive test documentation and managing a large number of findings can be challenging
B. Testing quality can vary significantly depending on the skills of individual testers
C. Coordinating with testers in various locations and time zones, with cultural differences and language barriers, can be challenging
D. Sharing software with external testers poses data security and confidentiality risks

Question 4

You have been assigned as Test Analyst on a project that will deliver quotes for motor insurance. The amount quoted depends upon the combined values of twelve variables, that are resolved by a set of business rules.
What should be your MAIN task during the test analysis activity?

A. Identify the tests that should be executed against the current version of the test
B. Identify additional tests based on lessons learned from earlier test execution activity
C. Use a test design technique to model the way in which the quote will be produced
D. Select or adapt existing test cases for use in subsequent regression testing

Question 5

You are working on a project to build a purchasing system. The main requirements for the system are that it shall:
* Allow users to enter details of items that they wish to have purchased and, from these details, create a purchase request.
* Take each purchase request through a workflow that will allow the requestor's line manager to approve the request, reject it or return it for clarification / modification.
* Forward approved requests to the Purchasing Department.
* Allow purchasers to find the best available supplier for each approved request and place the request on that supplier as a purchase order.
The solution is being developed according to the company's traditional V-model methodology. The requirements are clearly documented and include a business process model.
System testing has finished and the test manager has asked you, the senior TA, to identify any parts of the product that should be focused on during acceptance testing. The results of this may be used to adjust the acceptance test plan.
You are using defect cluster analysis, only counting defects with severity levels 1 to 3, ignoring low severity levels 4 and 5. Function point analysis was used for estimating, so you have used function points as the unit of size for the various functional areas of the product. No numeric estimates of expected defect quantities were made for them individually but, as a result of product risk analysis, these functional areas have been ranked according to the amount of product risk that was predicted in them, with risk ranking 1 being the highest and
5 the lowest; the thoroughness of the testing performed so far has been proportional to that. The results are presented in the table below.
