Percentage of work done in test environment preparation is a metric that measures how much of the required test environment setup has been completed. This metric is useful for monitoring the test progress because it indicates whether the test environment is ready for executing the planned test cases or not.

 Frequency 0, 1, 5, 6; Duration 0, 1, 30, 60, 61 is the correct test set of valid and invalid boundary values applying 2-value boundary value analysis1 . Boundary value analysis is a technique that tests the values at and near the boundaries of an input domain or output range1 . A 2-value boundary value analysis tests two values for each boundary: one valid value and one invalid value1 . For Frequency, the valid boundaries are 1 and 5, so the test set should include one valid value (1 or 5) and one invalid value (0 or 6) for each boundary. For Duration, the valid boundaries are 1 and 60, so the test set should include one valid value (1 or 60) and one invalid value (0 or 61) for each boundary. The other options are incorrect test sets of valid and invalid boundary values applying 2-value boundary value analysis. Option A only includes valid values for each boundary, but not invalid values. Option B includes invalid values that are not adjacent to the boundaries (59 seconds and 60 minutes 1 second). Option D includes more than two values for each boundary (0, 1, 2 for Frequency; 0, 1, 30 for Duration).

This is an example of a failure, which is an event in which a component or system does not perform a required function within specified limits. In this case, the calculator software failed to perform the addition function correctly and gave an incorrect result.
