TypeError: Cannot read property 'getText' of undefined

Question

I'm stuck on that error: TypeError: Cannot read property 'getText' of undefined When I run my test in Protractor v.4.0.14 What I understand is that getText() is not able to get a text from table cell, because CSS selector is not picking it correctly or I'm using wrong method to retrieve text from the cell?!

My page object file's code:

var HomePage = function(){

    //methods
    this.clearForm = function(){
        element(by.css("#nameInput")).clear();
        element(by.css("#surnameInput")).clear();
        element(by.css("#emailInput")).clear();
        element(by.css("#phoneInput")).clear();
    };

    this.fillForm = function(name, surname, email, phone){
        element(by.css("#nameInput")).sendKeys(name);
        element(by.css("#surnameInput")).sendKeys(surname);
        element(by.css("#emailInput")).sendKeys(email);
        element(by.css("#phoneInput")).sendKeys(phone);
    };

    this.clickSave = function(){
        element(by.css("#saveBTN")).click();
    };

    this.clickSearch = function(){
        element(by.css("#searchBTN")).click();
    };

    this.getResult = function(row, column){
        element(by.css("#result > tr:nth-child("+row+") > td:nth-   child("+column+")"));
    };

    this.clickEdit = function(row){ 
        element(by.css("input.button-primary:nth-child("+row+")")).click();
    };

    this.clickRemove = function(row){
        element(by.css("input.button:nth-child("+row+")")).click();
    };

    this.clickDeleteLocalStorage = function(){
        element(by.css("#delAllBTN")).click();
    };

};
module.exports = new HomePage();

And here is spec file's code:

describe("Contact book", function(){

    var page = require('./page/home_page.js');

    //input data
    var name = 'Vladimir';
    var surname = 'Putin';
    var email = 'ilovekgb@ivan.ru';
    var phone = '+01 1234 567';

    beforeEach(function(){
        browser.ignoreSynchronization = true;
        browser.get("https://ddaawwiidd.github.io/contactbook/");
    });

    it("Should be able to save new contact", function(){
        page.fillForm(name, surname, email, phone);
        page.clickSave();
    });

    it("Should be able to search for saved contact", function(){
        page.clearForm();
        page.fillForm(name, surname, email, phone);
        page.clickSearch();
        var result = page.getResult(1,1).getText(); //that's the part causing the error
        expect(result).toContain('Vladimir');
    });

    it("Should be able to edit contact details", function(){
        page.fillForm(name, surname, email, phone);
        page.clickSearch();
        page.clickEdit(1);
        page.clearForm();
        page.fillForm('Barack', 'Obama', email, phone);
        page.clickSave();
    });

    it("Should be able to remove contact", function(){
        page.fillForm('Barack','','','');
        page.clickSearch();
        page.clickRemove(1);
    });

    it("Should be able to list all saved contacts", function(){
        page.clearForm();
        page.clickSearch();
    });

    xit("Should be able to delete localStorage", function(){
        page.clickDeleteLocalStorage(); 
        expect(page.getFirstRowResult().isDisplayed()).toBe(false);
    });


 });

This is screenshot of HTML:

And this is error message:

I'm 4 days fresh with Protractor, so it may be a stupid mistake.

Any other suggestions regarding code are welcome too.

Thank you.

Answer 1

In addition to @AdityaReddy's answer few points to stress on:

getText() returns a promise, you have resolve it to get the actual text. Basically most of the Protractor API methods return promises.You could also do something like this in your spec.js-

it("Should be able to search for saved contact", function(){
    page.clearForm();
    page.fillForm(name, surname, email, phone);
    page.clickSearch();

    page.getResult(1,1).getText().then(function (text) { 
    expect(text).toContain('Vladimir');
 }); 
 // or you could directly use expect which resolves the promise internally.

    expect(page.getResult(1,1).getText()).toContain('Vladimir');
});

Answer 2

Your getResult() doesnt return an elementFinder object, hence it throws undefined error

You need return the element back. Please check below

this.getResult = function(row, column){
        return element(by.css("#result > tr:nth-child("+row+") > td:nth-   child("+column+")"));
    };
