ansible/molecule

Features

• Idempotency Testing - Implements a specialized validator that executes automation multiple times to verify that no unintended changes occur after the initial run.
• Ansible Testing Frameworks - Provides a comprehensive framework for linting, validating, and testing Ansible roles and collections.
• State Validation - Runs full sequences of provisioning and verification to confirm playbooks achieve the intended system state.
• Driver-Based Provisioning - Implements modular drivers to provision and tear down ephemeral test targets like containers and virtual machines.
• Automated Testing Containers - Spins up ephemeral container instances as test hosts and destroys them after executing configuration playbooks.
• Infrastructure Idempotency Validators - Executes automation multiple times to ensure no unintended changes occur after the initial successful run.
• Infrastructure Idempotency Testing - Confirms that repeated applications of infrastructure code result in the same state without unexpected changes.
• Test Lifecycle Phases - Orchestrates the full test process through a sequence of distinct phases including convergence and destruction.
• Testing Lifecycle Management - Coordinates the complete testing process by mapping actions to provisioning and resource destruction phases.
• Outcome Verification - Executes verification tasks after automation to compare the actual system state against expected functional outcomes.
• Automated Infrastructure Testing - Validates Ansible roles and collections by executing them across containers, virtual machines, and cloud infrastructure.
• Ephemeral Testing Environments - Spins up and tears down isolated, short-lived container or VM instances to validate infrastructure code.
• Test Orchestration - Coordinates the lifecycle, dependencies, and execution order of infrastructure test environments.
• Test Image Templates - Builds custom container images using direct files or templates to define specific test environments.
• Dynamic Inventory Resolution - Resolves test hosts using static files or dynamic scripts to ensure production-parity environments.
• Ansible Playbooks - Provides native execution of Ansible playbooks to verify infrastructure state on provisioned test targets.
• Automation Inventory Management - Enables the use of external files and scripts to manage target machine groups for automation testing.
• Environment Verifications - Verifies that inventory configurations and dynamic sources are reachable and properly configured before test execution.
• Cross-Environment Test Harnesses - Executes test scenarios across diverse targets like Linux containers or network simulations to ensure consistent automation behavior.
• Test Sequence Control - Allows defining the custom order of testing phases to create tailored validation workflows.
• Parallel Test Execution - Runs multiple test environments and scenarios concurrently to reduce total validation time.
• Parallel Test Execution - Executes multiple test scenarios simultaneously to reduce the total duration of the infrastructure validation suite.
• Targeted Test Execution - Allows running a specific subset of test cases or full lifecycles for a named environment to isolate failures.
• Cross-Platform Test Execution - Verifies that automation code behaves consistently across different operating systems and cloud providers.
