/**

|
|
* Test to verify that empty .env files are created for build packs that require them.
|
||
|
|
*
|
||
|
|
* This test verifies the fix for the issue where deploying a Docker image without
|
||
|
|
* environment variables would fail because Docker Compose expects a .env file
|
||
|
|
* when env_file: ['.env'] is specified in the compose file.
|
||
|
|
*
|
||
|
|
* The fix ensures that for 'dockerimage' and 'dockercompose' build packs,
|
||
|
|
* an empty .env file is created even when there are no environment variables defined.
