General

• Bumping to PHP 8.0
• Bumping to Laravel 7.x

CI/CD

• Within Github Actions workflow, we moved the setting of job specific environment variables to be global for the whole workflow.
• Each Github Actions job can upload its own artifact on failure.
• Failing Github Actions jobs will upload files from the database/snapshots/ directory instead of tests/Browser/db-dump/.

Tests

• Created a DatabaseMigrations trait to help speed up tests.
• Addressed usage of deprecated faker methods.
• Modifications to tests and associated traits to conform to PhpUnit 9.5 & PHP 8.0.
• Overriding the assertContains method in Dusk tests to auto-populate a better a failure message if one isn't provided.

Database

• Modified database migrations so that table, column & index names are stored in variables.
• Replaced the spatie/db-dumper composer package with spatie/laravel-db-snapshots.
• Deleted the tests/Browser/db-dump/ directory. No longer needed while using the artisan snapshot command(s).

Misc.

• Custom artisan command argument and option names are stored & accessed from variables instead of hardcoding AND storing in a variable.
• Modified the App\User model and associated database factory to better reflect the associated database table schema.
• Updated benchmarking documentation.
• Fixed some typos.
