1# Crosvm End to End Tests 2 3These tests run a crosvm VM on the host to verify end to end behavior. They use a prebuilt guest 4kernel and rootfs, which is downloaded from google cloud storage. 5 6## Running with locally built kernel/rootfs 7 8If the test needs to run offline, or you want to make changes to the kernel or rootfs, you have to 9specify the environment variables `CROSVM_CARGO_TEST_KERNEL_BINARY` and 10`CROSVM_CARGO_TEST_ROOTFS_IMAGE` to point to the right files. 11 12The use_local_build.sh script does this for you: 13 14`$ source guest_under_test/use_local_build.sh` 15 16## Uploading prebuilts 17 18Note: Only Googlers with access to the crosvm-testing cloud storage bin can upload prebuilts. 19 20To upload the modified rootfs, you will have to uprev the `PREBUILT_VERSION` variable in: 21 22- `./guest_under_test/PREBUILT_VERSION` 23 24and [request a permission](http://go/crosvm/infra.md?cl=head#access-on-demand-to-upload-artifacts) 25to become a member of the `crosvm-policy-uploader` group. Then run the upload script to build and 26upload the new prebuilts. **Never** try to modify an existing prebuilt as the new images may break 27tests in older versions. 28
