Test of the _detectSymbols macro

This test uses the SASUnit framework. It initializes a test scenario and declares global macro variables `g_my_error`, `g_my_warning`, and `g_my_note`. These variables are then reset to `_NONE_`. The `_detectSymbols` macro is called with these variables as output parameters. The script then verifies, via assertions, that `g_my_error` has been set to 'ERROR', `g_my_warning` to 'WARNING', and `g_my_note` to 'NOTE', thus confirming the proper functioning of `_detectSymbols`. This code is compatible with SAS^© Viya^™ 4 as it uses standard SAS^© macro language features.

Data Analysis

Type : CREATION_INTERNE

No external data is used. The script works with global macro variables defined and manipulated directly within the code to simulate and verify the status of symbols (error, warning, note).

1 Code Block

Macro Declarations and Initializations Data

Explanation :
This block initializes the test scenario and declares the global macro variables `g_my_error`, `g_my_warning`, and `g_my_note`. These variables are then initialized to `_NONE_` before the call to the tested macro, to ensure a known starting state.

Test Case Execution

Explanation :
The test case is defined and the `_detectSymbols` macro is called. The previously declared global macro variables are passed by reference (`r_error_symbol`, `r_warning_symbol`, `r_note_symbol`), allowing `_detectSymbols` to modify their values according to its internal logic. `%endTestcall` marks the end of the tested code execution.

3	%endTestcall;

SASUnit Assertions

Explanation :
Three `%assertEquals` assertions are used to verify that the `_detectSymbols` macro has correctly updated the global macro variables. It is expected that `g_my_error` contains 'ERROR', `g_my_warning` contains 'WARNING', and `g_my_note` contains 'NOTE'. `%endTestcase` closes the individual test case.

SASUnit Scenario End

Explanation :
This block marks the end of the global test scenario defined by `%initScenario`. It is a standard closing command of the SASUnit framework.
