# 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_VERSION`
|
||
|
|
- `src/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.
