Teflo is an orchestration software that controls the flow of a set of testing scenarios. It is a standalone tool written in Python that includes all aspects of the workflow. It allows users to provision machines, deploy software, execute tests against them and manage generated artifacts and report results.

Teflo Provides structure, readability, extensibility and flexibility by :

providing a YAML file to express a test workflow as a series of steps.
enabling integration of external tooling to execute the test workflow as defined by the steps.

Teflo can be used for an E2E (end to end) multi-product scenario. Teflo handles coordinating the E2E task workflow to drive the scenario execution.

What does an E2E workflow consist of?

At a high level teflo executes the following tasks when processing a scenario.

Provision system resources
Perform system configuration
Install products
Configure products
Install test frameworks
Configure test frameworks
Execute tests
Report results
Destroy system resources
Send Notifications

Teflo has following stages

Provision - Create resources to test against (physical resources, VMs etc)

Orchestrate - Configure the provisioned resources (e.g. install packages on them, run scripts, ansible playbooks etc)

Execute - Execute tests on the configured resources

Report - Send or collect logs from the tests run

Notification - Send email/gchat/slack notification during each stage of teflo run or at the end based on the set triggers

Cleanup - Cleanup all the deployed resources.

These stages can be run individually or together.

Teflo follows a plugable architechture, where users can add different pluggins to support external tools Below is a diagram that gives you a quick overview of the Teflo workflow
