To answer this question, you need to understand the concept of a test scenario.
Option A) The waiting process during test execution for multiple virtual users to arrive at a certain point - This option is incorrect. This describes the concept of synchronization, where virtual users are coordinated to arrive at a certain point in the test execution.
Option B) Playback the script in multi-user mode - This option is incorrect. Playback refers to the execution of a recorded script, but it does not specifically refer to a test scenario.
Option C) The events that occur during each testing session - This option is correct. A test scenario is defined as a sequence of events or actions that occur during a testing session. It outlines the steps and conditions required to execute a specific test case.
Option D) Recording a script - This option is incorrect. Recording a script is the process of capturing user actions on an application to create a test script, but it does not fully encompass the definition of a test scenario.
The correct answer is Option C. This option is correct because a test scenario is defined as the events that occur during each testing session.
