Motivation
Tinybird local allows us to do integration testing of the SDK directly in CI without a tinybird account. This will be super helpful as we make more changes to the SDK. Moreover, providing some utilities to make it easier to start up tb local and deploying projects programmatically as part of tests can be useful for downstream projects.
This PR introduces an integration testing harness that automatically spins up tinybird-local, deploys a test project, and then runs tests against it. This is fully integrated into pytest, so no external commands need to be run first, only pytest.
The main new concepts are
TinybirdLocalContainerandTinybirdCli, which allow us to programmatically interact with the tb cli and tinybird local. There's also atests/integrationfolder which has fixtures that automatically start up tinybird local and deploy the test project to it.Changes
