Given a test 34 configuration, it will perform an end-to-end test of a Chrome OS update 35 payload. A test configuration can be given as command-line arguments (see 36 below) or instantiated inline as local varibles. 37 38 To invoke this test locally: 39 40 test_that <DUT-IPADDR> autoupdate_EndToEndTest --args="<ARGLIST>" 41 42 where ARGLIST is a whitespace separated list of the following key=value pairs. 43 Values pertaining to the test case include: 44 45 name=TAG name tag for the test (e.g. 'nmo', 'npo' or 'fsi') 46 update_type=full|delta type of update being applied, either 'full' or 'delta' 47 source_release=REL source image release version (e.g. 2672.0.0) 48 target_release=REL target image release version (e.g. 2673.0.0) 49 source_payload_uri=URI URI of the source full payload. None means don't 50 install a source image (assume it's preinstalled). 51 source_archive_uri=URI (optional) URI of where the artifacts for the source 52 image (e.g. stateful update) are located. If not 53 provided, the test will attempt using the same 54 location as source_payload_uri. This is required for 55 any test where the location of the full (source) 56 payload is separate from that of its build artifacts 57 (e.g. it is in gs://chromeos-releases/). 58 target_payload_uri=URI URI of the target payload 59 target_archive_uri=URI (optional) URI of where the artifacts for the target 60 image (e.g. stateful update) are located. If not 61 provided, the test will attempt using the test job's 62 repo ID (if present), otherwise default to the same 63 location as target_payload_uri. Normally, this is 64 only needed for local (non-AFE) runs where the 65 payload location is separate from that of the build 66 artifacts (e.g. it is in gs://chromeos-releases). 67 68 69 To run locally: 70 1. Find the Google Storage URIs of the images you want to use during the test. 71 You can choose payloads from this bucket: gs://chromeos-releases/ 72 73 Sample from gs://chromeos-releases: 74 gs://chromeos-releases/dev-channel/samus/9433.0.0/payloads/chromeos_9433.0 75 .0_samus_dev-channel_full_test.bin-1e2db02f3bd9d9ebe74dc81fc7038919 76 77 2. Choose the devserver you want to use. 78 This test uses a devserver to control the autoupdate. You can point to a 79 devserver on your workstation to aid debugging or you can choose to use a 80 devserver in the lab. 81 82 To start your own devserver, run this (outside the chroot): 83 src/platform/dev/devserver.py --port=8084 84 85 For a devserver running on your workstation use 127.0.0.1 as the hostname. 86 For a devserver running in the lab the port is usually 8082. 87 88 Add this line to src/third_party/autotest/files/shadow_config.ini in the [CROS] section: 89 dev_server = http://<hostname>:<port> 90 91 The devserver needs to be able to reach the DUT you choose in the next 92 section. Look up the dev_server_common.ini.erb (in repo chromeos_admin) for 93 dev_server & restricted_subnet fields to pick a devserver in the same 94 subnet with the testing DUT. 95 96 3. Choose the DUT you want to use for the test. 97 You can use a DUT on your desk connected to corp or you can lock a DUT 98 in the lab for use in the test. 99 100 4. Setup ssh correctly. 101 You will need to setup a number of ssh keys and then copy them to 102 your chroot so that you can ssh into a devserver from there. 103 104 Run ssh-keygen to generate your id_rsa and id_rsa.pub files into ~/.ssh/ 105 106 Download the testing_rsa ssh keys from here: 107 https://chromium.googlesource.com/chromiumos/chromite/+/master/ssh_keys 108 Save both to ~/.ssh 109 chmod 600 ~/.ssh/testing_rsa* (otherwise permissions are too loose and 110 will be ignored) 111 112 Add these lines to your ~/.ssh/config 113 Host *.cros 114 User root 115 IdentityFile /usr/local/google/home/<your ldap here>/.ssh/testing_rsa 116 117 You should now be able to ssh into DUTs in the lab without a password. 118 119 To ssh into lab devservers you need to download the devserver key from: 120 https://valentine.corp.google.com/#/show/1519247593151324 121 122 Save the file to ~/.ssh/devserver and run chmod 600 on it. 123 Then add these lines to your ~/.ssh/config 124 125 Host <devserver hostname> 126 User chromeos-test 127 IdentityFile %d/.ssh/devserver 128 UserKnownHostsFile /dev/null 129 StrictHostKeyChecking no 130 Protocol 2 131 PreferredAuthentications publickey 132 133 Check that you can now ssh into a lab devserver without a password. 134 135 Finally and most importantly, copy the ssh files to your chroot's .ssh 136 folder so you can ssh from there. 137 138 5. Make sure you have your gsutil permissions (your .boto file). 139 Your .boto file must be available inside the chroot. 140 cp ~/.boto chroot/home/<user>/ 141 142 Make sure the gsutil command is available outside the chroot (note: 143 the gsutil package in Ubuntu is not what you're looking for.) 144 145 6. Kick off the test with test_that from a chroot. e.g 146 test_that <IP OF DUT> autoupdate_EndToEndTest 147 --args="target_release=10906.0.0 148 source_payload_uri='gs://chromeos-releases/canary-channel/nami/10760.0 149 .0/payloads/chromeos_10760.0.0_nami_canary-channel_full_test 150 .bin-cee25d306d164f7514e26efb34f8f57d' 151 target_payload_uri='gs://chromeos-releases/canary-channel/nami/10906.0 152 .0/payloads/chromeos_10760.0.0-10906.0.0_nami_canary-channel_delta_test 153 .bin-98f9af8d919605fc3ee1391eaa79c7e6' 154 source_release=10760.0.0 update_type=delta" 155 156 7.
