SCONS: Run target always, not only if updated

Question

Based on SCONS run target I created a basic SCONS script to build and then run my unit tests:

test = env.Program(
    target='artifacts/unittest',
    source= sources + tests
)

Alias(
    'test',
    test,
    test[0].abspath
)

After I modified the code, this works great:

> scons test
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
g++ [...]
[Lots of compiler output]
unittest.exe
===============================================================================
All tests passed (22 assertions in 4 test cases)

If I run scons test now again without changing the code, it sees no need for building again, which is correct, but also doesn't run the tests again:

> scons test
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: `test' is up to date.
scons: done building targets.

But, obviously, I want the tests to be run even if they are not rebuilt:

> scons test
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
scons: `test' is up to date.
scons: done building targets.
unittest.exe
===============================================================================
All tests passed (22 assertions in 4 test cases)

Is what would be the easiest way wo get this result?

Answer 1

Fixed it now by Creating a PseudoBuilder using AddMethod to concat a Builder and a Command:

env.AddMethod(
    lambda env, target, source:
        [
            env.Program(
                target=target,
                source=source
            )[0],
            env.Command(
                target,
                source,
                '.\\$TARGET'
            )[0]
        ]
    ,
    'BuildAndRun'
)

env.Alias(
    'test',
    env.BuildAndRun(
        target='artifacts/unittest',
        source= sources + tests
    )
)

Works as expected so far:

> scons test
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
g++ [...]
[Lots of compiler output]
.\artifacts\unittest
===============================================================================
All tests passed (22 assertions in 4 test cases)
> scons test
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
.\artifacts\unittest
===============================================================================
All tests passed (22 assertions in 4 test cases)

Only drawback: the backslash in the command makes me windows-dependent.

Any Opinions?
