Validation of the data itself entered in the field (character limit)

Question

Suppose I have a field that has a limit of 15 characters.

In my test i add 16 characters.

How do I validate that they were entered only 15 characters in the field?

browser.findElement(By.xpath("//input[@class='form-control ng-untouched ng-pristine ng-valid ui-inputtext ui-corner-all ui-state-default ui-widget']")).sendKeys("1236767676786983");

WebElement campoID = browser.findElement(By.xpath("//input[@class='form-control ng-untouched ng-pristine ng-valid ui-inputtext ui-corner-all ui-state-default ui-widget']"));

String texto = campoID.getText();
assertEquals("123676767678698", texto);

Hello,

Normally we use gettext() for most elements, but for "input" the text is kept in the page structure differently, it is under the attribute "value".

Then you should use the "getattribute" method by passing the "value" attribute to capture the input text.

Thus:

String texto = campoID.getAttribute("value");

To validate the amount of characters the best is to assert the amount of characters not in the text:

Thus remaining:

assertEquals(15, texto.length())

To be more readable you can add a message indicating the validation you are doing.

assertEquals("O tamanho do texto esperado é ", 15, texto.length())
//A resposta será: "O tamanho do texto esperado é (15) was (16)" 
//Caso o resultado seja falso.
