Autotests introduction - Codeception + PHP Basics

Autotests
introduction
By Artur Babyuk

Agenda
● What is good auto QA test
● Codeception
○ Settings - YAML
○ Test code
○ Test organisation
○ Good practices
● Selenium, BrowserStack, PhpBrowser
● Jenkins
● And fun

Autotest is
1. Necessary
2. Stable
3. Simple
4. ...

Codeception
http://codeception.com/
https://gitlab.dyninno.net/qa-automation/TravelFrontendSeleniumTestingSystem

How we can run needed tests?
1. By file name or folder -> ./codecept run tests/acceptance/asap
2. By groups -> ./codecept run -g request -g phones
P.S. in documentation we see -> php codecept run -> ./codecept run do the same
thing

How to run tests on iOS or other platforms?

Settings
tests/acceptance.suite.yml
In config section:
Default settings for all envs
So by default we are using:
WebDriver at BrowserStack
Windows 10 + Chrome

Custom env
Envs:
nojs: with PhpBrowser
Testing asap.com project
local_asap: WebDriver
Running at our Selenium

Env (environment)
Is used for:
1. Testing host - run tests for prod, stage, or dev
2. Testing platform - run tests for iOS, Windows, Linux; Chrome or Safari
3. Testing resolution - run tests for laptops, full hd or 4K monitors
4. Tests executor - local Selenium, Selenium Grid, BrowserStack or PhpBrowser
5. Tests misc - GIFs of errors, Allure reporting...

Running tests for needed env
./codecept run acceptance --env local_asap

Combining all
./codecept run acceptance --env local_asap -g request --debug
P.S. --debug option for seeing all steps and additional information, but this make
tests slower

Jenkins
Is tool that executes tests (do the job) for you and where you can find test outputs
http://192.168.3.85/view/ASAP
Login: manager
Pass: xxxxxxx701

Create Jenkins job
1. Создать Item
2. Copy from -> use most green job name
3. Configure job at “Настройки” -> “Сборка” -> Exec command
4. Edit command where line ./codecept run …

Job :(
cd /home/gitlab-runner/TravelFrontendSeleniumTestingSystem/
git pull
./codecept run acceptance --env local_asap -g disclaimers

So, we can execute tests, how to write them?

Methodology
● Get the data from test subject
● Compare actual data with expected

Test are written in PHP
So we will use some PHP

How can we get the test subject, if it is not
on current page???
1. Navigate to the page -> $I->amOnPage('/about');
2. Click -> $I->click('#nav a');
3. Fill forms -> $I->fillField('.user[email]','artur@babyuk.com');
4. Ask developers for help

What the heck just happened with $I-click()?
It is CSS selector, but there is many options
More info: https://blog.mozilla.org/webqa/2013/09/26/writing-reliable-locators-
for-selenium-and-webdriver-tests/

Comparing actual with expected
1. $I->see('Thank you'); $I->dontSee('Please enter email');
2. $I->seeElement('.success'); $I->dontSeeElement('.error');
3. $I->seeInCurrentUrl('/result-page'); $I->dontSeeInCurrentUrl('/oops');
4. Many other helper methods

But this is not so simple
There is problems - animation, network, designers and developers…
Some elements can lagg time to time or be not visible, but we need to autotest it
1. $I->wait(10);
2. $I->waitForElementVisible('.success', 10);
3. $I->waitForText('Success, we will contact you shortly', 30);
4. $I->waitForAllScriptsLoaded($I);
5. $I->scrollTo('footer');

Sometimes we need only to get data
1. $aLinkText = $I->grabMultiple('a');
2. $aLinks = $I->grabMultiple('a', 'href');
3. $url = $I->grabFromCurrentUrl();
4. $heading = $I->grabTextFrom('h1')

There is a lot of needed methods
http://codeception.com/docs/modules/WebDriver#Actions
You can also develop your common methods and put them here:
https://gitlab.dyninno.net/qa-
automation/TravelFrontendSeleniumTestingSystem/blob/master/tests/_support/
WebHelper.php

But tests are not so simple, how about
conditions?
https://clevertechie.com/php/5/php-if-else-statement

How about loops?
https://clevertechie.com/php/6/php-for-loop

How we can store expected results?
https://clevertechie.com/php/3/php-array

How we can loop an array?
https://clevertechie.com/php/8/php-foreach-loop

How about other useful functions?
1. count($elements);
2. strpos($airlineLogoHref, 'airlineNotFound') !== FALSE;
3. str_replace('-', ' ', $url);
4. preg_match('/[^A-Za-z0-9]/i', $onlyText);
5. empty($textOrArray);
6. date('m/d/Y', strtotime('+7 day'));
