Why when I run my phpunit test I get an empty response but the same route/user in Postman behaves as expected?

While writing my tests for API the route api/users should return a list of users. In Postman works as it should but in my phpunit test returns status 200 but an empty response hence assertJsonStructure() fails.

I have used the same user/password for Postman and for phpUnit. I added dd() trying to debug the response and get an empty body.

The test

/** @test */                                                                                                                                                  
         public function testUserCanListUsers()                                                                                                                        
         {

The expected output which I get on Postman

The factory()->make() method does not save a record in the database. Therefore, when you make your api call in your test, you don't have any users, hence the empty response.

factory()->create() is used to actually save the record. So, just change your factory()->make() to factory()->create() and you should get a user in your response.
