A wine storage system uses a control device that measures the wine cell temperature T (measured in °C, rounded to the nearest degree) and alarms the user if it deviates from the optimal value of 12, according to the following rules:  if T = 12, the system says, “optimal temperature”  if T < 12, the system says, “temperature is too low!”  if T > 12, the system says, “temperature is too high!” You want to use the 3-point boundary value analysis (BVA) to verify the behavior of the control device. A test input is a temperature in °C provided by the device. What is the MINIMAL set of test inputs that achieves 100% of the desired coverage?

Which of the following statements describe a valid test objective?

Which of the following options shows an example of test activities that contribute to success?

You have been assigned as a tester to a team producing a new system incrementally. You have noticed that no changes have been made to the existing regression test cases for several iterations and no new regression defects were identified. Your manager is happy, but you are not. Which testing principle explains your skepticism?

You work in a team that develops a mobile application for food ordering. In the current iteration the team decided to implement the payment functionality. Which of the following activities is a part of test analysis?

Which of the following factors (i-v) have SIGNIFICANT influence on the test process? i. The SDLC ii. The number of defects detected in previous projects iii. The identified product risks iv. New regulatory requirements forcing formal white-box testing v. The test environment setup
