Avalanche e2e test suites

  • Works with fixture-managed networks.
  • Compiles to a single binary with customizable configurations.

Running tests

go install -v github.com/onsi/ginkgo/v2/ginkgo@v2.0.0
ACK_GINKGO_RC=true ginkgo build ./tests/e2e
./tests/e2e/e2e.test --help

./tests/e2e/e2e.test \
--avalanchego-path=./build/avalanchego

See tests.e2e.sh for an example.

Filtering test execution with labels

In cases where a change can be verified against only a subset of tests, it is possible to filter the tests that will be executed by the declarative labels that have been applied to them. Available labels are defined as constants in describe.go with names of the form *Label. The following example runs only those tests that primarily target the X-Chain:

./tests/e2e/e2e.test \
  --avalanchego-path=./build/avalanchego \
  --ginkgo.label-filter=x

The ginkgo docs provide further detail on how to compose label queries.

Adding tests

Define any flags/configurations in e2e.go.

Create a new package to implement feature-specific tests, or add tests to an existing package. For example:

.
└── e2e
    ├── README.md
    ├── e2e.go
    ├── e2e_test.go
    └── x
        └── transfer.go
            └── virtuous.go

e2e.go defines common configuration for other test packages. x/transfer/virtuous.go defines X-Chain transfer tests, labeled with x, which can be selected by ./tests/e2e/e2e.test --ginkgo.label-filter "x".

Testing against a persistent network

By default, a new ephemeral test network will be started before each test run. When developing e2e tests, it may be helpful to create a persistent test network to test against. This can increase the speed of iteration by removing the requirement to start a new network for every invocation of the test under development.

To use a persistent network:

# From the root of the avalanchego repo

# Build the testnetctl binary
$ ./scripts/build_testnetctl.sh

# Start a new network
$ ./build/testnetctl start-network --avalanchego-path=/path/to/avalanchego
...
Started network 1000 @ /home/me/.testnetctl/networks/1000

Configure testnetctl to target this network by default with one of the following statements:
 - source /home/me/.testnetctl/networks/1000/network.env
 - export TESTNETCTL_NETWORK_DIR=/home/me/.testnetctl/networks/1000
 - export TESTNETCTL_NETWORK_DIR=/home/me/.testnetctl/networks/latest

# Start a new test run using the persistent network
ginkgo -v ./tests/e2e -- \
    --avalanchego-path=/path/to/avalanchego \
    --ginkgo.focus-file=[name of file containing test] \
    --use-persistent-network \
    --network-dir=/path/to/network

# It is also possible to set the AVALANCHEGO_PATH env var instead of supplying --avalanchego-path
# and to set TESTNETCTL_NETWORK_DIR instead of supplying --network-dir.

See the testnet fixture README for more details.

Skipping bootstrap checks

By default many tests will attempt to bootstrap a new node with the post-test network state. While this is a valuable activity to perform in CI, it can add considerable latency to test development. To disable these bootstrap checks during development, set the E2E_SKIP_BOOTSTRAP_CHECKS env var to a non-empty value:

E2E_SKIP_BOOTSTRAP_CHECKS=1 ginkgo -v ./tests/e2e ...

Functions

func AddEphemeralNode added in v1.10.10 

func AddEphemeralNode(network testnet.Network, flags testnet.FlagsMap) testnet.Node

Add an ephemeral node that is only intended to be used by a single test. Its ID and URI are not intended to be returned from the Network instance to minimize accessibility from other tests.

func CheckBootstrapIsPossible added in v1.10.11 

func CheckBootstrapIsPossible(network testnet.Network)

Verify that a new node can bootstrap into the network.

func ContextWithTimeout added in v1.10.10 

func ContextWithTimeout(duration time.Duration) context.Context

Helper simplifying use of a timed context by canceling the context on ginkgo teardown.

func DefaultContext added in v1.10.10 

func DefaultContext() context.Context

Helper simplifying use of a timed context configured with the default timeout.

func DescribeCChain added in v1.10.10 

func DescribeCChain(text string, args ...interface{}) bool

DescribeCChain annotates the tests for C-Chain.

func DescribePChain added in v1.7.17 

func DescribePChain(text string, args ...interface{}) bool
