You can fetch the whole workable repository from here[1]. One patch[2] to sbsigntools must also be applied so that we wil be able to sign an image with intermediate certificates. It is required here for testing. (snip) Test ==== - The added new pytest (test_signed_intca.py) passed locally. - Travis CI passed, except the new pytest added here due to a new feature in sbsigntools as mentioned above. (the latest vesion is still running though.) ===>8=== I guess that you are not using the latest source of sbsigntools. > If you replace as follows in test/run you get the extra skip messages: > > %s/--bd/-ra --bd/g > > > --- > > test/py/tests/test_efi_secboot/conftest.py | 134 ++++++++++++++++- > > test/py/tests/test_efi_secboot/defs.py | 8 +- > > test/py/tests/test_efi_secboot/openssl.cnf | 48 +++++++ > > .../test_efi_secboot/test_signed_intca.py | 135 ++++++++++++++++++ > > 4 files changed, 317 insertions(+), 8 deletions(-) > > create mode 100644 test/py/tests/test_efi_secboot/openssl.cnf > > create mode 100644 test/py/tests/test_efi_secboot/test_signed_intca.py > > > > diff --git a/test/py/tests/test_efi_secboot/conftest.py b/test/py/tests/test_efi_secboot/conftest.py > > index c6709700a876..20d0cbf3ab01 100644 > > --- a/test/py/tests/test_efi_secboot/conftest.py > > +++ b/test/py/tests/test_efi_secboot/conftest.py > > @@ -37,7 +37,7 @@ def efi_boot_env(request, u_boot_config): > > global HELLO_PATH > > > > image_path = u_boot_config.persistent_data_dir > > - image_path = image_path + '/' + EFI_SECBOOT_IMAGE_NAME > > + image_path = image_path + '/' + EFI_SECBOOT_IMAGE_NAME + '.img' > > I would prefer a separate constant for > EFI_SECBOOT_IMAGE_NAME + '_intca.img' > to ensure that conftest.py and test_signed_intca.py use the same value. 'separate constant to use the same value?' I don't get your point. Anyhow, *.py files don't use a image file name directly, but get it from a test fixture.
