An application is subjected to a constant load for an extended period of time as part of a performance test While running this test, the response time of the application steadily slows down, which results in a requirement not being met This slowdown is caused by a memory leak where the application code does not properly release some of the dynamically allocated memory when it is no longer needed.

A company wants to reward each of its salespeople with an annual bonus that represents the sum of all the bonuses accumulated for every single sale made by that salesperson. The bonus for a single sale can take on the following four values: 3%, 5%, 7% and 10% (the percentage refers to the amount of the single sale). These values are determined on the basis of the type of customer (classified as "Basic" or "Premium") to which such sale was made, and on the amount of such sale classified into the following three groups G1, G2 and G3:
• [G1]: less than 300 euros
• [G2]: between 300 and 2000 euros
• [G3]: greater than 2000 euros

[iii]. The test team will not have an adequate requirements specification (since many requirements will still be missing) by the time test design and analysis activities should begin according to the test plan.
[IV]. Following a failure, the system is unable to continue to maintain its pre-failure operation and some data becomes corrupted.
Which of the following statements is TRUE?

The unscripted tests produced by the tester's experience during such session belong to which one of the following testing quadrants?
Which TWO of the following are benefits of continuous integration?
I. Allows earlier detection and easier root cause analysis of integration problems and conflicting changes.
II. Removes the need for manual test analysis, design and execution.
Hi. Removes the dependency on automated regression packs when integrating larger systems, or components.
iv. Gives the development team regular feedback on whether the code is working.
