2. Which of the following is a type of testing that verifies the behavior of individual units of source code?

   1. Unit Testing
   2. Integration Testing
   3. System Testing
   4. Acceptance Testing

   Answer: A. Unit Testing

   Unit testing focuses on testing the smallest testable parts of an application, typically functions or methods, in isolation.

3. In Pytest, how can you run tests that are marked with a specific name?

   1. `pytest -m marker_name`
   2. `pytest --select marker_name`
   3. `pytest mark marker_name`
   4. `pytest run -m marker_name`
   Show answer

   Answer: A. `pytest -m marker_name`

   The `-m` flag in Pytest is used to select tests based on their assigned markers. This allows for categorizing and running specific groups of tests.

4. What is a 'test case'?

   1. A set of conditions or variables under which a tester will determine whether a system under test satisfies requirements or works correctly.
   2. A framework for executing tests.
   3. A collection of test suites.
   4. A tool for reporting test results.
   Show answer

   Answer: A. A set of conditions or variables under which a tester will determine whether a system under test satisfies requirements or works correctly.

   A test case is a detailed description of a series of actions, inputs, and expected outputs to verify a specific feature or functionality of the software.

5. In Pytest, what is the purpose of `pytest.mark.parametrize`?

   1. To run a single test function multiple times with different arguments.
   2. To mark a test as belonging to a certain category.
   3. To skip tests that meet certain criteria.
   4. To define test fixtures.
   Show answer

   Answer: A. To run a single test function multiple times with different arguments.
