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

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

You are working on a project to replace an old sales and merchandising system with a new system that will be based on modern platforms. The old system Is still in production but is poorly documented and expensive to maintain. The new version will be developed using modern technology. The main requirements for the system are that it shall:
* Load sales data, sent electronically from the stores each evening, into a central database.
* Produce actual sales reports for the merchandisers, whose job is to manage stock levels in stores.
* Produce sales forecast reports based on a combination of sales history and forecasting parameters. The parameters will be entered by the merchandisers into a browser-based front end and the reports will be produced overnight. The users will be able to see the reports next day, on screen or in print, by requesting this through the browser.
Requirements 1 and 2 are satisfied by the existing system and will be rewritten with no significant changes.
Requirement 3 is new. The development will use your company's Agile SDLC, with 2-week iterations.
Technical skill levels in the team are high and the approach to automate test execution is aggressive. Each requirement will be specified with user stories, will be released only when complete, and will need more than one iteration. The main business benefit will come from requirement 3, which depends on the other two requirements, and the stakeholders are keen to get this into production as soon as possible.
Release planning has begun for requirement 3 and you need to know at a high level what the testing scope will be, to ensure that the correct resources will be available. Which functional test techniques will be MOST effective for this release?
a) Domain testing
b) Combinatorial testing
c) Random testing
d) CRUD testing
e) Scenario-based testing
f) Decision table testing
g) Exploratory testing

• A. a), b) and d)
• B. c), e) and f)
• C. b), c) and g)
• D. a), e) and f)

The test basis for your latest project contains the activity diagram that is shown below. The business architect has confirmed that this model has been reviewed and approved by the stakeholders.

Which of the following conclusions is correct?

• A. The diagram may contain a defect but this cannot be confirmed until test cases have been designed from it
• B. The diagram contains at least one defect because it contains an internal inconsistency
• C. The diagram may contain a defect but this cannot be confirmed until the results of the tests created from it are known
• D. The diagram is correct because it has been reviewed and approved by the stakeholders
