| -- OBJECTIVE: |
| -- Check that the subprograms defined in package Ada.Strings.Bounded are |
| -- available, and that they produce correct results, especially under |
| -- conditions where truncation of the result is required. Specifically, |
| -- check the subprograms Overwrite (function and procedure), Delete, |
| -- Function Trim (blanks), Trim (Set characters, function and procedure), |
| -- Head, Tail, and Replicate (characters and strings). |
| -- |
| -- TEST DESCRIPTION: |
| -- This test, in conjunction with tests CXA4006, CXA4007, and CXA4008, |
| -- will provide coverage of the most common usages of the functionality |
| -- found in the Ada.Strings.Bounded package. It deals in large part |
| -- with truncation effects and options. This test contains many small, |
| -- specific test cases, situations that are often difficult to generate |
| -- in large numbers in an application-based test. These cases represent |
| -- specific usage paradigms in-the-small. |
| -- |
| -- |
| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 10 Apr 95 SAIC Corrected errors in Procedure Overwrite subtests. |
| -- 01 Nov 95 SAIC Fixed bugs for ACVC 2.0.1. |
