Testing file upload using phpunit can be challenging. Below are two ways you can test file uploads in phpunit integration tests.

When you’re testing an API with file upload, API Payload and File Payload must be sent separately.

Using fake file:

public function testUpload()
{
    $fileData = [
        'attachment' => UploadedFile::fake()->create('fakefile.pdf', 100)
    ];    

    $data = [
        'first_name' => 'John',
        'last_name' => 'Doe',
    ];    

    $url = 'http://localhost/upload';    

    $this->call(
      'POST', 
      $url, $data, [], $fileData, 
      $this->transformHeadersToServerVars([
        'Authorization' => 'Bearer xxxx'
      ])
    );    

    $this->assertResponseOk();
}

Using Original/Real file:
Here UploadedFile function has 6th parameter called testing which needs to be set true.

public function testUpload()
{
    $filePath = storage_path('realfile.pdf'); 

    $fileData = [
        'attachment' => new UploadedFile($file, null, null, null, null, true); 
    ]; 

    $data = [
        'first_name' => 'John',
        'last_name' => 'Doe',
    ];    

    $url = 'http://localhost/upload';    

    $this->call(
      'POST', 
      $url, $data , [], $fileData, 
      $this->transformHeadersToServerVars([
        'Authorization' => 'Bearer xxxx'
      ])
    );    

    $this->assertResponseOk(); 
}
