Crosvm Integration Tests
These tests run a crosvm VM on the host to verify end to end behavior. They use a prebuilt guest kernel and rootfs, which is downloaded from google cloud storage.
Running with locally built kernel/rootfs
If the test needs to run offline, or you want to make changes to the kernel or
rootfs, you have to specify the environment variables
CROSVM_CARGO_TEST_KERNEL_BINARY and CROSVM_CARGO_TEST_ROOTFS_IMAGE to point
to the right files.
The use_local_build.sh script does this for you:
$ source guest_under_test/use_local_build.sh
Uploading prebuilts
Note: Only Googlers with access to the crosvm-testing cloud storage bin can upload prebuilts.
To upload the modified rootfs, you will have to uprev the PREBUILT_VERSION
variable in:
./guest_under_test/PREBUILT_VERSIONsrc/third_party/chromiumos-overlay/chromeos-base/crosvm/crosvm-9999.ebuild
Then run the upload script to build and upload the new prebuilts. Never try to modify an existing prebuilt as the new images may break tests in older versions.
