OK the -e has helped. Now I am back with:

1/1 (100.00%) /usr/bin/python -tt test/sconstest-issue_1.py
scons returned 2

So back where I was with the SCons_Testing_Framework. I'll now delete my
fork of that.

So the question is how to get the test to have the tool available.  The
SCons_Protobuf project looks like:

.
├── __init__.py
├── protoc.py
├── README.rst
└── test
    ├── Image
    │   └── SConstruct
    └── sconstest-issue_1.py

and sconstest-issue_1.py is:

        import TestSCons
        from os.path import abspath, dirname, isfile
        test = TestSCons.TestSCons()
        test.file_fixture('../protoc.py')
        if not test.where_is('protoc'):
            test.skip_test('Required executable, protoc, not found,
        skipping test.')
        test.dir_fixture('Image')
        test.run()
        test.pass_test()

The '../protoc.py' is being found by the test framework, but is not
being made available to the SConstruct:

        environment = Environment(
            tools=['protoc'],
        )
        
        proto_files = environment.Protoc(
            [],
            Glob('build/protobuf/*.proto'),
            PROTOCPROTOPATH=['build/protobuf',],
            PROTOCPYTHONOUTDIR='build/protobuf', # set to None to not generate python
            PROTOCOUTDIR = 'build/protobuf', # defaults to same directory as .proto
            # PROTOCCPPOUTFLAGS = "dllexport_decl=PROTOCONFIG_EXPORT:", too
        )


Sorry to be a pain getting this working. All help gratefully accepted.
