End-to-end Tests

Structure

e2e Package

The e2e package defines an integration testing suite used for full end-to-end testing functionality. This package is decoupled from depending on the Osmosis codebase. It initializes the chains for testing via Docker files. As a result, the test suite may provide the desired Osmosis version to Docker containers during the initialization. This design allows for the opportunity of testing chain upgrades in the future by providing an older Osmosis version to the container, performing the chain upgrade, and running the latest test suite.

The file e2e_suite_test.go defines the testing suite and contains the core bootstrapping logic that creates a testing environment via Docker containers. A testing network is created dynamically with 2 test validators.

The file e2e_test.go contains the actual end-to-end integration tests that utilize the testing suite.

Currently, there is a single test in e2e_test.go to query the balances of a validator.

initialization Package

The initialization package introduces the logic necessary for initializing a chain by creating a genesis file and all required configuration files such as the app.toml. This package directly depends on the Osmosis codebase.

upgrade Package

The upgrade package starts chain initialization. In addition, there is a Dockerfile init-e2e.Dockerfile. When executed, its container produces all files necessary for starting up a new chain. These resulting files can be mounted on a volume and propagated to our production osmosis container to start the osmosisd service.

The decoupling between chain initialization and start-up allows to minimize the differences between our test suite and the production environment.

Running Locally

To build chain initialization image

Please refer to tests/e2e/initialization/README.md

To build the debug Osmosis image

    make docker-build-e2e-debug

### Environment variables

Some tests take a long time to run. Sometimes, we would like to disable them
locally or in CI. The following are the environment variables to disable
certain components of e2e testing.

- `OSMOSIS_E2E_SKIP_UPGRADE` - when true, skips the upgrade tests.
If OSMOSIS_E2E_SKIP_IBC is true, this must also be set to true because upgrade
tests require IBC logic.

- `OSMOSIS_E2E_SKIP_IBC` - when true, skips the IBC tests tests.

- `OSMOSIS_E2E_SKIP_STATE_SYNC` - when true, skips the state sync tests.

- `OSMOSIS_E2E_SKIP_CLEANUP` - when true, avoids cleaning up the e2e Docker
containers.

- `OSMOSIS_E2E_FORK_HEIGHT` - when the above "IS_FORK" env variable is set to true, this is the string
of the height in which the network should fork. This should match the ForkHeight set in constants.go

- `OSMOSIS_E2E_UPGRADE_VERSION` - string of what version will be upgraded to (for example, "v10")

#### VS Code Debug Configuration

This debug configuration helps to run e2e tests locally and skip the desired tests.
