better phpunit setup for testing laravel sail/docker

I am working on a laravel 8 project. and i have to write lots of test. I am using vscode editor, and so been using caleb porzio 's better phpunit extension. extesion for vscode. i can't setup it for running written tests inside docker container although i am defining everything as it is said in the github.com documentation.

these are typical configurations/settings that laravel ships with. i have just added my own configurations. all those are working independently.

here is my settings.json file

  "better-phpunit.docker.enable": true,
  "better-phpunit.docker.command": "docker-compose exec laravel.test",
  "better-phpunit.docker.paths": {
    "/home/rex/rajesh/code/erworks/codalaya/src": "/var/www/html"
  },

here is the output of terminal when running better phpunit command.

> Executing task in folder Nuxt v2: docker-compose exec laravel.test /var/www/html/vendor/bin/phpunit /var/www/html/tests/Feature/CourseFeatureTest.php --filter '^.*::this_test_runs( .*)?$' --configuration /var/www/html/phpunit.xml <

The terminal process "/bin/bash '-c', 'docker-compose exec laravel.test /var/www/html/vendor/bin/phpunit /var/www/html/tests/Feature/CourseFeatureTest.php --filter '^.*::this_test_runs( .*)?$' --configuration /var/www/html/phpunit.xml'" terminated with exit code: 1.

Terminal will be reused by tasks, press any key to close it.
