   public function testBasicTest() {
      $this->artisan('nova:create', [
         'name' => 'My New Admin panel'
      ])
      ->expectsQuestion('Please enter your API key', 'apiKeySecret')
      ->expectsOutput('Authenticating...')
      ->expectsQuestion('Please select a version', 'v1.0')
      ->expectsOutput('Installing...')
      ->expectsQuestion('Do you want to compile the assets?', 'yes')
      ->expectsOutput('Compiling assets...')
      ->assertExitCode(0);
   }
}

Explanation of Code

Here a new class named “ArtisanCommandTest” is created under test cases module. It includes a basic function testBasicTest which includes various functionalities of assertions.
The artisan command expectsQuestion includes two attributes. One with question and other with an apiKeySecret. Here, the artisan validates the apiKeySecret and verifies the input sent by user.
The same scenario applies for the question “Please select a version” where a user is expected to mention a specific version.
