// This is a placeholder image. Replace it with a real diagram illustrating the architecture of a typical test environment.
//
// Consider including the following elements:
// - Client application
// - Test environment manager (the plugin)
// - Docker Compose
// - Testcontainers
// - Databases (e.g., PostgreSQL, MySQL)
// - Message queues (e.g., RabbitMQ, Kafka)
// - Other services (e.g., Redis, Memcached)
// - Environment variables
// - Network connections
//
//  The diagram should illustrate how the test environment manager orchestrates these components to create isolated and reproducible test environments.
//
// Example (textual representation, to be visually diagrammed):
//
// [Client Application] --> [Test Environment Manager]
//
// [Test Environment Manager] --> [Docker Compose] --> [Containers (Database, Message Queue, Other Services)]
//
// [Test Environment Manager] --> [Testcontainers] --> [Containers (Database, Message Queue, Other Services)]
//
// [Test Environment Manager] <--> [Environment Variables]
//
// Consider using a diagramming tool like draw.io, Lucidchart, or similar to create the visual representation.
// Ensure the diagram is clear, concise, and easy to understand.
//
// When replacing this placeholder, ensure the filename is "test_environment_diagram.png".
//
// You can use a tool like ImageMagick to optimize the image for web use:
// `convert test_environment_diagram_original.png -strip -interlace Plane -gaussian-blur 0.05 -quality 85% test_environment_diagram.png`
//
//  This placeholder image is a 1x1 transparent pixel.  It is here to meet the requirement for a .png file.
