This commit adds a relatively thorough test suite for
kdumpctl reset-crashkernel [--fadump=[on|off|nocma]] [--kernel=path_to_kernel] [--reboot]
as implemented in commit 140da74 ("rewrite reset_crashkernel to support
fadump and to used by RPM scriptlet").
grubby have a few options to support its own testing,
- --no-etc-grub-update, not update /etc/default/grub
- --bad-image-okay, don't check the validity of the image
- --env, specify custom grub2 environment block file to avoid modifying
the default /boot/grub2/grubenv
- --bls-directory, specify custom BootLoaderSpec config files to avoid
modifying the default /boot/loader/entries
So the grubby called by kdumpctl is mocked as
@grubby --grub2 --no-etc-grub-update --bad-image-okay --env=$SPEC_TEST_DIR/env_temp -b $SPEC_TEST_DIR/boot_load_entries "$@"
in the tests. To be able to call the actual grubby in the mock function [1],
ShellSpec provides the following command
$ shellspec --gen-bin @grubby
to generate spec/support/bins/@grubby which is used to call the actual grubby.
kdumpctl has implemented its own version of updating /etc/default/grub
in _update_kernel_cmdline_in_grub_etc_default. To avoiding writing to
/etc/default/grub, this function is mocked as outputting its name and
received arguments similar to python unitest's assert_called_with.
