To associate a function library to a test, you can use the "Test Settings" command.
Option A) Run Options - This option is incorrect because the "Run Options" command is used to configure the test execution settings, such as the test iteration count and the test execution order.
Option B) Test Settings - This option is correct because the "Test Settings" command allows you to configure various settings related to the test, including associating a function library.
Option C) View Options - This option is incorrect because the "View Options" command is used to configure the display settings within the testing tool, such as the font size and color scheme.
Option D) Function Definition Generator - This option is incorrect because the "Function Definition Generator" is not a command typically used to associate a function library to a test. It is more likely a tool or feature provided by some testing frameworks or IDEs to generate function definitions based on a specific input.
Therefore, the correct answer is B) Test Settings because it allows you to associate a function library to a test.
