Each Buildkite plan has test execution inclusions, which vary depending on the plan type and the number of users in your organization.
You can find the test execution details for a run at the bottom of the run page, and your organization's total usage in Settings.
The Usage page is available on every Buildkite plan and shows a breakdown of job minutes and test executions for your organization.
The test executions usage page graphs the total executions over the organization's billing periods. It includes a breakdown of usage by suite and a CSV download of usage over the period.
Your organization's usage is also accessible in the GraphQL API.
