A test case is a set of preconditions, inputs, actions, expected results and postconditions developed based on test conditions. A test condition is a statement about what to test in terms of measurable coverage criteria from analysis of the test basis. A test plan is a description of the test objectives to be achieved and the means and the schedule for achieving them. A test oracle is a source to determine expected results to compare with the actual result of the system under test.

The correct answer is A, as it includes the items that would be most useful to include in the defect report. A defect report is a document that describes and records any anomaly found during testing2. A defect report typically includes information such as:

• The expected results
• The actual results
• A description of the defect in order to reproduce, including screenshots and database dumps

These items are useful to include in the defect report, as they help the developers to understand and fix the defect2. Option B is incorrect, as it includes an item that would not be useful to include in the defect report. The urgency and priority to fix this is not useful to include in the defect report, as it is determined by the test manager or other stakeholders based on various factors such as severity, impact, risk, and business value2. Option C is incorrect, as it omits an item that would be useful to include in the defect report. The actual results are useful to include in the defect report, as they show what happened when the defect occurred2. Option D is incorrect, as it omits two items that would be useful to include in the defect report. The expected results and a description of the defect in order to reproduce are useful to include in the defect report, as they show what should have happened and how to replicate the defect2.

Having an independent test function in an organisation can improve defect finding during reviews and testing, because independent testers can provide a different perspective and have less bias than developers or other stakeholders. Independent testers can also focus on testing activities without being influenced by development pressures or deadlines12. The other options are not valid reasons for having an independent test function. Option B is more related to code reviews, which can be done by developers themselves or by peers. Option C is not beneficial, because communication between developers and testers is essential for effective testing and defect resolution. Option D is not directly related to the test function, but to the test management and reporting processes12.

2400, 1000, 2301 are test case inputs that each fall into a different equivalence partition1. Equivalence partitioning is a black box test design technique that divides the input domain of a system into partitions of equivalent data2. Each partition should contain data that is expected to be treated the same by the system2. Therefore, only one test case input from each partition is needed to test the system’s behaviour2. In this question, the input domain of the system is the time of travel, which can be divided into three partitions based on the fare rules:

• Peak-time tariff: This partition contains all the times between 0600 and 1000 (inclusive), which are subject to a higher fare.
• Off-peak tariff: This partition contains all the times between 1001 and 2259 (inclusive), which are subject to a lower fare.
• No service: This partition contains all the times between 2300 and 0559 (inclusive), which are not valid for travel.

Therefore, to test the system’s behaviour for each partition, we need to choose one test case input from each partition. Among the options given in this question, only D contains one test case input from each partition. 2400 belongs to the no service partition, 1000 belongs to the peak-time tariff partition, and 2301 belongs to the off-peak tariff partition. Therefore, D is the correct answer.
