From: Johannes Schindelin <johannes.schindelin@gmx.de>

To test the Scalar command, create a test script in contrib/scalar/t
that is executed as `make -C contrib/scalar test`. Since Scalar has no
meaningful capabilities yet, the only test is rather simple. We will add
more tests in subsequent commits that introduce corresponding, new
functionality.

Note: This test script is intended to test `scalar` only lightly, even
after all of the functionality is implemented.

A more comprehensive functional (or: integration) test suite can be
found at https://github.com/microsoft/scalar; It is used in the workflow
https://github.com/microsoft/git/blob/HEAD/.github/workflows/scalar-functional-tests.yml
in Microsoft's Git fork. This test suite performs end-to-end tests with
a real remote repository, and is run as part of the regular CI and PR
builds in that fork.

Since those tests require some functionality supported only by
Microsoft's Git fork ("GVFS protocol"), there is no intention to port
that fuller test suite to `contrib/scalar/`.
