How do I make the stepper motor perform a complete revolution?

This code works continuously with intervals, I want it to one full turn and stop.
Obs(the relays no control the motor )

#include <AccelStepper.h>
// Define a stepper and the pins it will use
AccelStepper stepper(AccelStepper::DRIVER, 5, 2);
int pos = 50;
int teste;
//Porta ligada ao pino IN1 do modulo
int porta_rele1 = 7;
void setup()
{ 
  Serial.begin(9600);
  stepper.setEnablePin(8);
  stepper.setMaxSpeed(4000.0);//0
  stepper.setAcceleration(4000.0);//0
  stepper.setCurrentPosition(0); //zero
  pinMode(porta_rele1, OUTPUT);
}
void loop()
{
while (Serial.available()>0)
  teste = Serial.read () ; '-0';
  if (teste == 116)
    {  
            digitalWrite(porta_rele1, HIGH);  //Liga rele 1
       Serial.println(teste);
    digitalWrite(porta_rele1, LOW); //Desliga rele 1
if ((stepper.distanceToGo() != 0)) {
    stepper.run();
}
    if (stepper.distanceToGo() == 0)
      {
        delay(500);
        pos = -pos;
        stepper.moveTo(pos);
      }
    stepper.run();
   }
  }

How many steps per revolution? Do you think it would be a good idea to move that many steps instead of just 50 steps?

The usual way to make a stepper motor move one revolution is to tell it to move 200 steps (or however many there are in a revolution).

Please use the AutoFormat tool to indent your code consistently and make it easier to read.

You need something more like:

setup()
{
  stepper.setEnablePin(8);
  stepper.setMaxSpeed(4000.0);//0
  stepper.setAcceleration(4000.0);//0
}

loop()
{
  stepper.run();  // must call this all the time, so every time through loop.  Don't use delay()

  if (Serial.available()>0)   // use if, not while...
  {
    char teste = Serial.read () ;
    if (teste == 116)
      stepper.move (200) ;  // initiate relative move - AccelStepper library does the rest.
  }
}
