Fake Pinentries for Test Suites
|
|
|
|
|
===============================
|
|
|
|
|
|
|
|
|
|
If you're writing a test suite, it should use one of these pinentries
|
|
|
|
|
by setting the following line in $GNUPGHOME/gpg-agent.conf:
|
|
|
|
|
|
|
|
|
|
pinentry-program /path/to/fake-pinentry.ext
|
|
|
|
|
|
|
|
|
|
Note that different fake-pinentry programs have been supplied here in
|
|
|
|
|
different languages, with the intent of making them available to
|
|
|
|
|
developers who have different languages available.

|
|
|
|
|
reusable by any project. Feel free to copy them into your own
|
|
|
|
|
project's test suite.

Rationale
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
If you're implementing software that uses GnuPG, you probably want a
|
|
|
|
|
test suite that exercises your code, and you may have some that
|
|
|
|
|
involve secret key material locked with a passphrase. However, you
|
|
|
|
|
don't want to require your developers to manually enter a passphrase
|
|
|
|
|
while tests are run, and you probably also don't want to deal with
|
|
|
|
|
alternate codepaths/workflows like using gpg's loopback pinentry.
|
|
|
|
|
|
|
|
|
|
The solution for this is to use a fake pinentry in your test suite,
|
|
|
|
|
one that simply returns a pre-selected passphrase. In this case, all
|
|
|
|
|
the other code follows the same path as normal, but the user
|
|
|
|
|
interaction is bypassed because the fake-pinentry is used instead.
|
|
|
|
|
|
|
|
|
|
