Unit test for the sas_set_index macro

This program performs unit tests to verify the correct functioning of the %sas^©_set_index macro. It tests the retrieval of index definitions on existing tables (sashelp.aarfm) and the absence of return on tables without indexes (sashelp.class), using assertions to validate the results.

Data Analysis

Type : SASHELP

Use of standard SASHELP demonstration tables (AARFM and CLASS) to ensure test portability.

1 Code Block

MACRO STATEMENT

Explanation :
Explicit declaration of the global macro variable 'indexx' used to capture test results.

Copied!

1	%global indexx;

2 Code Block

MACRO CALL

Explanation :
Nominal case test with index: Variable initialization, macro call on table 'sashelp.aarfm'. The assertion verifies that the composite index 'locale key' is correctly identified.

Copied!

1	%let indexx=
2	%sas_set_index(sashelp.aarfm, indexx);
3	%asserteq(locale key,&indexx.);
4

3 Code Block

MACRO CALL

Explanation :
Test case without index: Variable reinitialization, macro call on table 'sashelp.class'. The assertion verifies that no index is returned (empty value expected).

Copied!

1	%let indexx=
2	%sas_set_index(sashelp.class, indexx);
3	%asserteq(,&indexx.);
