Hi, in the case of your tests you already have an explicit dependency for -arm, this is the same but for riscv. So the change you'd need would only be like:
diff --git a/debian/tests/control b/debian/tests/control index 9ae95ea..f506ce8 100644 --- a/debian/tests/control +++ b/debian/tests/control @@ -1,2 +1,2 @@ Test-Command: make SNEK_NATIVE=/usr/bin/snek SNEK_ARM=/usr/share/snek/snek-arm SNEK_RISCV=/usr/share/snek/snek-riscv -C test check -Depends: @, qemu-system-arm, qemu-system-misc, gcc +Depends: @, qemu-system-arm, qemu-system-riscv, gcc
