# DESCRIPTION--------------------------------------------------------------------------
  # This job is responsible for validating a successful building of a player on WebGl standalone platform. 
  # This job WILL NOT execute any tests, we only validate the building process.
  # This is because WebGL runs in browser and for tests to be executed we would need to consider having a web server, browser automation and overall complex test setup which currently we don't have. 
  
# CONFIGURATION STRUCTURE--------------------------------------------------------------
  # Jobs configurations are generated using nested loops through:
    # 1. For the default project (project is used only as a context for the build).
    # 2. For all desktop platforms (Windows, Ubuntu, macOS)
    # 3. For all supported Unity Editor versions (For NGOv1.X it means 2021.3+)
  
# TECHNICAL CONSIDERATIONS----------------------------------------------------------------
  # WebGL requires IL2CPP scripting backend (Mono is not supported)
  # We are not using ARM64 architectures since we only perform a build action. x64 architectures are preferred for build phase (in order to optimize available resource usage)
  # We only perform build validation (no runtime testing)
  
# QUALITY CONSIDERATIONS--------------------------------------------------------------------
  # In the future we could try to implement an infrastructure to run test in webgl context but this could be quite complicated and would need to be evaluated if it's worth it
  # To see where this job is included (in trigger job definitions) look into _triggers.yml file
