The previous release of an in-house invoicing application was live for 6 months before beingreplaced by a later release.
* Before it went live, €1,500 had been spent on defect prevention and a further €4,500 had been spent on writing and running tests; these tests found 80 defects and the average cost of dealing with these was €50 each.
* By the time that it was replaced, defect reports from live running showed that pre-release testing had found only 80% of the defects that were present; the average cost of dealing with the defects that went live was 12 times that of the internal failures.
Which statement is TRUE?

Test Analysts are doing test design for a change request to an insurance comparison system. The system provides car insurance quotations, using data input by the user.
The change request states:-
Drivers must be aged between 17 to 85 years inclusive to qualify for insurance comparison.
The following Test Conditions have been identified:
1 Driver's age is less than the minimum
2. Driver's age is within the valid range
3. Driver's age is more than the maximum
The Test Strategy states the test techniques to be used include Equivalence Partitioning and Boundary Value Analysis. Using the Test Conditions and techniques stated in the Test Strategy, the following Test Cases have been created.
As the Test Manager you are reviewing these Test Cases for traceability to the Test Conditions and to ensure that the change request will be adequately tested in accordance with the Test Strategy.

An old stock control system is being decommissioned and replaced with a new system that has been running successfully in the live environment for the last few months. The stakeholders would like to -
* retain historical information held in the database to comply with their data retention policy (which requires order information to be retained for 7 years)
* query the historical information by running pre-written SQL queries.
* all commands must be invoked by keyboard as one of the end users is unable to use a mouse The pre-written SQL queries will be designed, developed and tested by the developers who are decommissioning the system and writing the data migration routine.
As the system to be decommissioned is integrated to other systems that will remain operational, the stakeholders have requested that testing incorporates all systems that are part of the stock control suite.
The stakeholders and project manager have identified the following risks, in priority order -
* 1st - Data has not been successfully migrated to an archived data store, resulting in the inability to query past stock levels and re-order details.
* 2nd - Historical data for the last 7 years is unavailable, resulting in the failure to meet the data retention policy.
* 3rd - Failure of existing systems within the stock control suite, adversely affecting the operational running of the business The risks are to form the basis of the test objectives. Which three of the following test activities, work products and/or resources achieves the test objectives?
a. Use of the live database to test the data migration does not corrupt or lose data b. A test plan detailing the test approach for ST. SIT & OT test levels c. Accessibility testing of the pre-defined SQL queries d. Security and Penetration testing of the archived database e Performance testing of the data migration exercise to ensure it completes in the time specified by the stakeholders f. Functional testing of the pre-defined SQL queries g. Regression testing of the end to end process for maintaining specified stock levels.

The organisational Test Strategy contains the following objectives:
1. A Risk-based lest approach must be adopted for all projects
2. Functional regression testing should start as soon as functional testing is complete
3. Automated tests may be run before or in parallel with manual tests
The project Test Plan has allocated 6 weeks to complete all test execution, with functional testing taking 3 weeks to execute, performance and security testing 2 weeks each and regression testing 1 week.
Which of the following options places the test suites (TS1 to TS5) in the correct order for test execution?
