Integration Tests

This directory contains instructions and test files on how to test the extension binary in an environment that looks like an Azure Linux Virtual Machine.

Requirements

• Install Docker Engine on Linux or Docker for Mac.
• Install Bats.

Testing Strategy

The integation tests use bats to run the scenarios as bash scripts.

To test the extension handler functionality, we simply:

• build a Docker image using test.Dockerfile
  • copy some files to make it look like a /var/lib/waagent dir
  • copy extension binary into the container
• remove the test container if it exists
• create a Docker container (name: test) from image
  • specify which handler subcommand will be invoked (e.g. fake-waagent install)
• push .settings file
  • do other things on the container that we need to craft the environment
• start the container
• collect the output from the command execution
• validate using the following:
  • check status code
  • validate output of the command
  • docker diff test to validate file changes in the container
  • copy files out of container and validate their contents

Running Tests

To run the integration tests, run the following commands from the repository root:

make binary
./integration-test/run.sh

If you are running on a linux host (a real linux host not WSL), you can use the command ./integration-test/run.sh --all to run all the tests.
