Using Ajax Request with PHPUnit and Laravel testing - php

Question

I am doing tests in Laravel with phpunit. I run a test that inserts that into a textbox and press a button. Then, theres an Ajax Post that sends the info to the server and returns the response. If I return a string has the following code, in the test I should get that string correct?
I have the following controller:
class MyController extends Controller{
public static function createNewComplaintStep_2(){
return "error";
}
}
The route:
Route::post('/createNewComplaint_Step2', 'MyController#createNewComplaintStep_2');
The view with form and ajax method:
<form id="formToSubmit" data-value="createNewComplaint_Step2" class="form-horizontal">
{!! csrf_field() !!}
<div class="form-group">
<label class="col-md-4 control-label">Customer:</label>
<div class="col-md-3">
<input class="form-control" name="customer_name" required>
</div>
</div>
<button type="submit" class="btn btn-success" name="subBTN"\>
</form>
(...)
<script>
$( '#formToSubmit' ).on( 'submit', function(e) {
var href = $(this).data('value');
e.preventDefault();
$.ajax({
type: "POST",
url: href,
data: $(this).serialize(),
success: function( msg ) {
$("#container-fluid").html(msg);
$('.se-pre-con').hide();
}
});
});
</script>
The phpunit test:
$this->visit('/createNew')
->type('NAME', 'customer_name')
->press('subBTN')
->see('error');
Is there something wrong? Because if I run the code, I get error
Failed asserting that the page contains the HTML [error]. Please check the content above
The content above is the view that is above. It seems that the ajax request is not working with phpunit.
Any suggestions??
thanks in advance!

You are working with jquery Ajax, which is a client side scripting language, basically executed in the browser at runtime it cannot be used by Laravel in tests.
Here your Ajax is not even execute so how can you get the string that's why this error is coming.
But you can try some extensions/drivers for laravel that can enable this feature.
Just check out Selenium:-
