To run tests for the project using docker/build-push-action, follow these step-by-step instructions.

Step 1: Set Up Your Environment

To begin, ensure that you have Docker installed on your machine and that you can run Docker commands. You should also have Node.js and TypeScript installed if you are testing TypeScript code. Finally, ensure that your Go environment is set up correctly.

Step 2: Clone the Repository

Clone the repository containing the docker/build-push-action project:

git clone https://github.com/docker/build-push-action.git
cd build-push-action

Step 3: Build the Docker Images

Before running tests, it is necessary to build the required Docker images. You can leverage the Dockerfile in the project. Use the following command to build the image:

docker build -t test-image .

Step 4: Running TypeScript Tests

If you need to run TypeScript tests, ensure you have the TypeScript test framework installed. An example of a TypeScript testing framework is Jest. To install Jest, run:

npm install --save-dev jest ts-jest @types/jest

You can configure Jest by creating a jest.config.js file:

module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'node',
};

To run TypeScript tests, use the following command:

npx jest

Step 5: Running Go Tests

For Go tests, ensure you are working with the correct Go module. The command below ensures that the tests will be run under the github.com/docker/build-push-action/test/go module:

cd test/go
go test ./...

Do not use the -mod=vendor flag. The output of the build can be verified by running:

go build

Step 6: Running HCL Tests

If the project involves HCL, you may be using terraform for tests. To perform tests on HCL files, you can use terraform commands. Navigate to the directory with your HCL files and run:

terraform init
terraform validate

Step 7: Running All Tests in a CI Environment

You can create a GitHub Actions workflow to automate the testing process. Below is an example .github/workflows/test.yml file:

name: CI

on:
  push:
    branches:
      - main
  pull_request:
    branches:
      - main

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Build Docker Image
        run: |
          docker build -t test-image .

      - name: Run TypeScript Tests
        run: |
          npm install
          npx jest

      - name: Run Go Tests
        run: |
          cd test/go
          go test ./...
        
      - name: Run HCL Tests
        run: |
          cd path/to/your/hcl/files
          terraform init
          terraform validate

Ensure all paths are correctly specified according to your project’s directory structure.

Step 8: Clean Up Resources

After running the tests, it is generally good practice to clean up any Docker images or containers you created during the testing process. Remove the Docker image with the following command:

docker rmi test-image

Refer to the official documentation of the docker/build-push-action for any updates or further information on optimizing your testing process. It’s crucial to note that these tests may produce varying results based on the specific configurations within your project.
