> To verify the successful end-to-end outcome of the filecoin protocol and filecoin implementations, under a variety of real-world and simulated scenarios.

These are the topics we are currently centering our testing efforts on. Our testing efforts include fault induction, stress tests, and end-to-end testing.
* We are recreating the scenarios that lead to slashing, as they are not readily seen in mono-client testnets.
* Context: slashing is the negative economic consequence of penalising a miner that has breached protocol by deducing FIL and/or removing their power from the network.
* We are recreating the proving fault scenarios and triggering them in an accelerated fasion (by modifying the system configuration), so that we're able to verify that the sector state transitions properly through the different milestones (temporary faults, termination, etc.), and under chain fork conditions.
* Context: every 24 hours there are 36 windows where miners need to submit their proofs of sector liveness, correctness, and validity. Failure to do so will mark a sector as faulted, and will eventually terminate the sector, triggering slashing consequences for the miner.
* Newly bootstrapped clients, and paused-then-resumed clients, are able to latch on to the correct chain even in the presence of a large number of forks in the network, either in the present, or throughout history.
* Induce forks in the network, create network partitions, simulate chain halts, long-range forks, etc. Stage many kinds of convoluted chain shapes, and network partitions, and ensure that miners are always able to arrive to consensus when disruptions subside.
* Induce network-wide, or partition-wide arrests, and investigate what the resulting chain is after the system is allowed to recover.
* Context: catch-up/rush mining is a dedicated pathway in the mining logic that brings the chain up to speed with present time, in order to recover from network halts. Basically it entails producing backdated blocks in a hot loop. Imagine all miners recover in unison from a network-wide disruption; miners will produce blocks for their winning rounds, and will label losing rounds as _null rounds_. In the current implementation, there is no time for block propagation, so miners will produce solo-chains, and the assumption is that when all these chains hit the network, the _fork choice rule_ will pick the heaviest one. Unfortunately this process is brittle and unbalanced, as it favours the miner that held the highest power before the disruption commenced.

This repository consists of [test plans](https://docs.testground.ai/concepts-and-architecture/test-structure) built to be run on [Testground](https://github.com/testground/testground).
The source code for the various test cases can be found in the [`lotus-soup` directory](https://github.com/filecoin-project/oni/tree/master/lotus-soup).
## Running the test cases
If you are unfamiliar with Testground, we strongly suggest you read the Testground [Getting Started guide](https://docs.testground.ai/getting-started) in order to learn how to install Testground and how to use it.
You can find various [composition files](https://docs.testground.ai/running-test-plans#composition-runs) describing various test scenarios built as part of Project Oni at [`lotus-soup/_compositions` directory](https://github.com/filecoin-project/oni/tree/master/lotus-soup/_compositions).
We've designed the test cases so that you can run them via the `local:exec`, `local:docker` and the `cluster:k8s` runners. Note that Lotus miners are quite resource intensive, requiring gigabytes of memory. Hence you would have to run these test cases on a beafy machine (when using `local:docker` and `local:exec`), or on a Kubernetes cluster (when using `cluster:k8s`).
Here are the basics of how to run the baseline deals end-to-end test case:
### Running the baseline deals end-to-end test case
1. Compile and Install Testground from source code from the [`oni`](https://github.com/testground/testground/pull/1083) branch.
* See the [Getting Started](https://github.com/testground/testground#getting-started) section of the README for instructions.
*`deals-e2e` - Deals end-to-end test case. Clients pick a miner at random, start a deal, wait for it to be sealed, and try to retrieve from another random miner who offers back the data.
*`drand-halting` - Test case that instructs Drand with a sequence of halt/resume/wait events, while running deals between clients and miners at the same time.
*`deals-stress` - Deals stress test case. Clients pick a miner and send multiple deals (concurrently or serially) in order to test how many deals miners can handle.
*`paych-stress` - A test case exercising various payment channel stress tests.
### Compositions part of `lotus-soup`
*`baseline-docker-5-1.toml` - Runs a `baseline` test (deals e2e test) with a network of 5 clients and 1 miner targeting `local:docker`
*`baseline-k8s-10-3.toml` - Runs a `baseline` test (deals e2e test) with a network of 10 clients and 3 miner targeting `cluster:k8s`
*`baseline-k8s-3-1.toml` - Runs a `baseline` test (deals e2e test) with a network of 3 clients and 1 miner targeting `cluster:k8s`
*`baseline-k8s-3-2.toml` - Runs a `baseline` test (deals e2e test) with a network of 3 clients and 2 miner targeting `cluster:k8s`
*`baseline.toml` - Runs a `baseline` test (deals e2e test) with a network of 3 clients and 2 miner targeting `local:exec`
Our current test plan `lotus-soup` is building programatically the Lotus filecoin implementation and therefore requires all it's dependencies. The build process is slightly more complicated than a normal Go project, because we are binding a bit of Rust code. Lotus codebase is in Go, however its `proofs` and `crypto` libraries are in Rust (BLS signatures, SNARK verification, etc.).
Depending on the runner you want to use to run the test plan, these dependencies are included in the build process in a different way, which you should be aware of should you require to use the test plan with a newer version of Lotus:
The Rust libraries are included in the Filecoin FFI Git submodule, which is part of the `iptestground/oni-buildbase` image. If the FFI changes on Lotus, we have to rebuild this image with the `make build-images` command, where X is the next version (see [Docker images changelog](#docker-images-changelog)
The Rust libraries are included via the `extra` directory. Make sure that the test plan reference to Lotus in `go.mod` and the `extra` directory are pointing to the same commit of the FFI git submodule. You also need to compile the `extra/filecoin-ffi` libraries with `make`.
*`cluster:k8s`
The same process as for `local:docker`, however you need to make sure that the respective `iptestground/oni-buildbase` image is available as a public Docker image, so that the Kubernetes cluster can download it.
Additional to the Filecoin FFI Git submodules, we are also bundling `proof parameters` in the `iptestground/oni-runtime` image. If these change, you will need to rebuild that image with `make build-images` command, where X is the next version. These parameters are downloaded automatically for `local:exec` if they are not present.
