Test of the %hassuffix macro

This SAS^© script is a set of unit tests for the %hassuffix macro. It evaluates different scenarios, including exact matches, partial suffix matches, non-matching cases, and handling of empty strings. The %asserteq macro is used to validate that the result of %hassuffix matches the expected value (1 for true, 0 for false).

Data Analysis

Type : CREATION_INTERNE

The data used are literal character strings passed directly as arguments to macro calls. No external or internal data (like SASHELP) is explicitly read or generated into datasets.

1 Code Block

Macro Call

Explanation :
Tests if the string 'abc' has 'abc' as a suffix. The expected result is 1 (true).

Copied!

1	%asserteq(1,%hassuffix(abc,abc));

2 Code Block

Macro Call

Explanation :
Tests if the string 'abc' has 'c' as a suffix. The expected result is 1 (true).

Copied!

1	%asserteq(1,%hassuffix(abc,c));

3 Code Block

Macro Call

Explanation :
Tests if the string 'abc' has 'a' as a suffix. The expected result is 0 (false).

Copied!

1	%asserteq(0,%hassuffix(abc,a));

4 Code Block

Macro Call

Explanation :
Tests the %hassuffix macro with empty arguments, which is generally interpreted as (empty string, empty string). The expected result is 1 (true).

Copied!

1	%asserteq(1,%hassuffix());

5 Code Block

Macro Call

Explanation :
Tests if an empty string has an empty string as a suffix. The expected result is 1 (true).

Copied!

1	%asserteq(1,%hassuffix(,));

6 Code Block

Macro Call

Explanation :
Tests if an empty string has 'a' as a suffix. The expected result is 0 (false).

Copied!

1	%asserteq(0,%hassuffix(,a));

7 Code Block

Macro Call

Explanation :
Tests if the string 'a' has an empty string as a suffix. The expected result is 1 (true).

Copied!

1	%asserteq(1,%hassuffix(a,));
