-= Integration tests for eth protocol and blockpool
-
-This is a simple suite of tests to fire up a local test node with peers to test blockchain synchronisation and download.
-The scripts call ethereum (assumed to be compiled in go-ethereum root).
-
-To run a test:
-
- . run.sh 00 02
-
-Without arguments, all tests are run.
-
-Peers are launched with preloaded imported chains. In order to prevent them from synchronizing with each other they are set with `-dial=false` and `-maxpeer 1` options. They log into `/tmp/eth.test/nodes/XX` where XX is the last two digits of their port.
-
-Chains to import can be bootstrapped by letting nodes mine for some time. This is done with
-
- . bootstrap.sh
-
-Only the relative timing and forks matter so they should work if the bootstrap script is rerun.
-The reference blockchain of tests are soft links to these import chains and check at the end of a test run.
-
-Connecting to peers and exporting blockchain is scripted with JS files executed by the JSRE, see `tests/XX.sh`.
-
-Each test is set with a timeout. This may vary on different computers so adjust sensibly.
-If you kill a test before it completes, do not forget to kill all the background processes, since they will impact the result. Use:
-
- killall ethereum
