Test Runner

The ioFog Test Runner provides a convenient way to run multiple smoke test suites on a deployed Edge Compute Network (ECN).

The suite by default does not run any non-smoke tests, i.e. tests that would invalidate or potentially break the ECN, therefore it can be used on staging a productions ECNs to verify correct deployment.

The following test suites are available:

• Controller REST API smoke tests
• Agent CLI smoke tests
• Basic microservice deployment integration tests

Note that some of additional test suites are automatically skipped as of this release of Test Runner.

Prerequisites

You must have iofogctl configured with its default namespace pointing to the ECN you want to test

Usage

Test suite	Description	Required configuration
Controller REST API smoke tests	Basic REST API tests on Controller instance	CONTROLLER CONTROLLER_EMAIL CONTROLLER_PASSWORD
Agent CLI smoke tests	Runs Agent tests by SSHing into the Agent nodes and interacting using Agent CLI	AGENTS
Basic microservice deployment integration tests	Sets up users and catalog entries, deploys and destroys microservices on each Agent	CONTROLLER CONTROLLER_EMAIL CONTROLLER_PASSWORD AGENTS

Example usage of the test runner with iofogctl configuration:

docker run --name test-runner \
        -v ~/.iofog/:/root/.iofog/ \
        iofog/test-runner:latest

Example usage of the test runner with endpoint configurations configuration:

docker run --name test-runner \
        -v ~/.ssh/my_iofog_agent_ssh_key:/root/.ssh/id_rsa \
        -e CONTROLLER="1.2.3.4:51121" \
        -e CONTROLLER_EMAIL="user@domain.com" \
        -e CONTROLLER_PASSWORD="#Bugs4Fun" \
        -e AGENT_USER="root" \
        -e AGENT_KEY="/root/.ssh/id_rsa" \
        iofog/test-runner:latest

Note that whenever AGENTS is specified, you need to mount appropriate ssh keys to /root/.ssh of the test-runner containers. The keys can be in any default SSH position: ~/.ssh/id_dsa, ~/.ssh/id_ecdsa, ~/.ssh/id_ed25519 and ~/.ssh/id_rsa.

Test Results

The output of this test-suite currently is a single XML File that is Junit-XML compliant. This can be used in development pipelines on most DevOps infrastructure to display test results in easy to consume factor.

This is used in Azure Pipelines to display each builds pass/fail for both entire test suites as well as for specific tests we may see multiple failures in, to help identify issues that may not be consistent.

The test output is file is TEST-RESULTS.xml and is stored in /root/test-results of the test-runner container.
