ACATS 3.0 User's Guide
5.2.2 Macro Defs Customization
There
was no change to the macro.dfs file from ACATS 2.6 to ACATS 3.0. A version of macro.dfs that was tailored for ACATS 2.6 should be valid for ACATS 3.0 unless
some implementation characteristics have changed.
Tests in files with the extension
.tst contain
symbols that represent implementation dependent values. The symbols are
identifiers with a initial dollar sign ('$'). Each symbol must be replaced
with an appropriate textual value to make the tests compilable. This
process is sometime known as
macro substitution.
The Macrosub program distributed with the ACATS can
automatically perform the required substitutions. This program reads
the replacement values for the symbols from the file macro.dfs
and edits all the .tst tests in the suite to make the needed
changes. It writes the resulting, compilable programs into files with
the same name as the original but with the extension .adt. A
sample macro.dfs is included with the ACATS; it contains descriptions
of all the symbols used in the test suite.
Substitutions using
the Macrosub program may be made as follows:
1.
Edit the file macro.dfs using values appropriate for the implementation.
Symbols that use the value of MAX_IN_LEN are calculated automatically
and need not be entered.
2.
Create a file called tsttests.dat that includes all of the .tst
test file names, and their directory locations if necessary. A version
of this file (without directory information) is supplied.
3.
Compile and bind MacroSub.
4.
Run MacroSub.
The program will replace all symbols in the .tst
files with values from macro.dfs. Test files with the original
test name but the extension .adt will contain the processable
tests. The original .tst files will not be modified.
