| # Antithesis Testing | ||
|
|
||
| This package supports testing with | ||
| [Antithesis](https://antithesis.com/docs/introduction/introduction.html), | ||
| a SaaS offering that enables deployment of distributed systems (such | ||
| as Avalanche) to a deterministic and simulated environment that | ||
| enables discovery and reproduction of anomalous behavior. | ||
|
|
||
| ## Package details | ||
|
|
||
| | Filename | Purpose | | ||
| |:-------------|:----------------------------------------------------------------------------------| | ||
| | compose.go | Enables generation of Docker Compose project files for antithesis testing. | | ||
| | avalanchego/ | Contains resources supporting antithesis testing of avalanchego's primary chains. | | ||
|
|
||
|
|
||
| ## Instrumentation | ||
|
|
||
| Software running in Antithesis's environment must be | ||
| [instrumented](https://antithesis.com/docs/instrumentation/overview.html) | ||
| to take full advantage of the supported traceability. Since the | ||
| Antithesis Go SDK only supports the amd64/x86_64 architecture as of this | ||
| writing, running of instrumented binaries on Macs (arm64) is not possible | ||
| without emulation (which would be very slow). To support test development | ||
| on Macs, a local build will not be instrumented. | ||
|
|
||
| ## Defining a new test setup | ||
|
|
||
| When defining a new test setup - whether in the avalanchego repo or | ||
| for a VM in another repo - following the example of an existing test | ||
| setup is suggested. The following table enumerates the files defining | ||
| a test setup: | ||
|
|
||
| | Filename | Purpose | | ||
| |:-------------------------------------------------------|:-------------------------------------------------------| | ||
| | scripts/build_antithesis_images.sh | Builds the test images to deploy to antithesis | | ||
| | scripts/build_antithesis_[test setup]_workload.sh | Builds the workload binary | | ||
| | scripts/tests.build_antithesis_images.sh | Validates the build of the test images | | ||
| | tests/antithesis/[test setup]/main.go | The entrypoint for the workload binary | | ||
| | tests/antithesis/[test setup]/Dockerfile.config | Defines how to build the config image | | ||
| | tests/antithesis/[test setup]/Dockerfile.node | Defines how to build the instrumented node image | | ||
| | tests/antithesis/[test setup]/Dockerfile.workload | Defines how to build the workload image | | ||
| | tests/antithesis/[test setup]/gencomposeconfig/main.go | Generates the compose configuration for the test setup | | ||
|
|
||
| In addition, github workflows are suggested to ensure | ||
| `scripts/tests.build_antithesis_images.sh` runs against PRs and | ||
| `scripts/build_antithesis_images.sh` runs against pushes. |
