Testground Hacks & Tricks

Testground

Testground is an open source tool developer by Protocol Labs. It’s designed to write large scale test plans for decentralized software.

Run testground on your server

Setup testground on a server,
Run the daemon with testground daemon.

On your machine, tunnel the testground port:

ssh MYMACHINE -N -L "8043:localhost:8042"

Then change the testground configuration to talk to your server:

in file: ~/testground/.env.toml

[client]
endpoint = "http://localhost:8043"

Now you can talk to your server without wasting time with proxies and stuff.

You can access your dashboard at http://localhost:8043/.

Import testground plans with a name

I use a lot of testground test plans, for example:

• https://github.com/libp2p/test-plans
• https://github.com/ipfs/go-ipfs/tree/master/testplans
• https://github.com/testground/testground/tree/master/plans

Each of these have different use cases, and I ended up with a lot of different plans. Also you need sort of a fixed names for your plan when you run them through a composition (to be explained).

When you import a plan you can give them a name, for example:

testground plan import --from ./ --name libp2p

Now all the plans in this folder can be addressed with the name libp2p. I can run:

testground run single --plan libp2p/ping-interop/go-v0.11 --testcase=ping --builder=doc..

Same for other projects, note the testground prefix in the plan name:

testground run single --plan=testground/example-rust --testcase=tcp-connect --builder=d..

You can use the run single command from anywhere because testground is actually looking for symbolic links in the ~/testground folder hence the naming prefix working.
