Show and hide div when clicking button

Navigation
0

I would like to click on the start test button, the counter div appears, and when I click next test, disappear the div id = 01 and only show id = 02 and so on, whenever I click on the next test it writes one text below the other.

Friend in the javascript part put this, if the button has already passed the old div, hide the old one ie testCounter - 1, tested and worked, follow the js fiddle link 

var testCounter = 0;
$(document).ready(function () {

    var sensorValor = '';
    var testEnabled = false;
    var roundedValue = 0;
    var contaBotao = 0;
    setInterval(function () {
      sensorValor = $('#counter').text();
    }, 100);

    $(".meubotao").click(function(e){

      var len = $('.testes div').length;

      //Se for a primeira vez ele é 0 então não entrará, mas na segunda vez 
       ele entra no if e pega a div anterior "testCounter-1"
      if (len > testCounter){
        if(contaBotao > 0){
            $('.testes div').eq(testCounter-1).hide();
        }
        contaBotao++;
        $('.testes div').eq(testCounter).show();
        testCounter++;
        if (len == testCounter){
          $('.meubotao').hide(); //ultima etapa ja chegou
        } else {
          $('.meubotao').html('Próxima Etapa');
          $('.meubotao').addClass('proxEtapa');
        }

      }
    });
      function showDivcontador(){
      document.getElementById("meubotao").style.display = 'block';
      }
});

I did not quite understand without code so I created this example based on the question. Any questions just use the comments, try to tailor your code with this my algorithm. 

var testeAtual = 0;
$('#btIniciarTeste').click(function(){
  if(this.value === 'Iniciar Teste'){
    this.value = 'Proximo Teste';
  }
  if(this.value === 'Finalizar'){
    window.location.reload();
  }
  
  
  $('.container-teste').find('div').hide();
  $($('.container-teste').find('div')[testeAtual]).show();
  
  if(!$('.container-teste').find('div')[testeAtual]){
    $('#btIniciarTeste').val('Finalizar');
  }
  
  
  
  testeAtual++;
});
.container-teste > div{
  display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><inputtype="button" value="Iniciar Teste" id="btIniciarTeste">
<div class="container-teste">
  <div>O que é JavaScript ? </div>
  <div>O que é PHP ?</div>
  <div>O que é Java ?</div>
</div>
