Environments

Let’s say that we run tests on both Linux and Windows machines. Then some of our runs will be coming from Windows machines, and some from Linux:

Commits with runs in different environments Commits with runs in different environments

This information will be captured in Flakiness Reports: each report contains a description of an environment that executed tests.

Environment is a simple list of key-value pairs. These can be generic properties, such as OS name and version:

os_version: 22.04
os_name: ubuntu
os_arch: x86_64

But also custom properties:

endpoint: staging
db_provider: mysql

All official reporters support FK_ENV_* environment variables for defining custom properties — the prefix is stripped and the key is lowercased. See Configuring Environments for the full setup.
