WDIO Frontend framework

Requirements

• Node version 14 or higher

Tools

This test suite is built on top of WebDriverIO using the Cucumber framework.

The language used is Typescript.

Quick start

Choose one of the following options:

1. Clone the git repo

2. Follow authentication steps

3. Install the dependencies (npm install)

Now you are ready to write your own features and run the test with npm test:local

Authentication

After the node installation Ensure that your %USERPROFILE%\.npmrc contains the Personal access token (PAT) to access the private @qasxp packages:

1. Ask to be added to D3 user groups.
2. Go to https://alm.deltatre.it/tfs/D3Alm/QA%20Automation/_packaging?_a=connect&feed=qasxp and select Connect to feed-> npm, then in the main page under Project setup please choose Other and not Windows.
3. Follow the instructions for Setup credentials.

Common issues

If during npm install you are facing the issue

code ERESOLVE ERESOLVE unable to resolve dependency tree

please run

npm cache clear --force
npm install --legacy-peer-deps 

How to write a test

Tests are written in Gherkin syntax that means that you write down what's supposed to happen in a real language. All test files are located in ./src/features/* and have the file ending .feature. You will already find some test files in that directory. They should demonstrate, how tests could look like. Just create a new file and write your first test.

myFirstTest.feature

Feature:
    In order to keep my product stable
    As a developer or product manager
    I want to make sure that everything works as expected

Scenario: Check title of website after search
    Given I open the url "http://google.com"
    When I set "WebdriverIO" to the inputfield "modal.input"
    And I press "Enter"
    Then I expect that the title is "WebdriverIO - Google Search"

Scenario: Another test
    Given ...

This test opens the browser and navigates them to google.com to check if the title contains the search query after doing a search. As you can see, it is pretty simple and understandable for everyone.

How to create Page Object Model

This repository use Page Object Model (POM) approach, mixed with BDD style.

To write yours Models go in the folder src/pom and create a new .ts file declaring a class that will contains the identifiers.

export class Header {
    public logo = ".icon-logo";
}

Then you have to register your models as custom world inside src/custom-world/pageObjectWorld.ts

export default class PageObjectWorld extends World {
    public header: Header;
    //define here other page object models

    constructor(options: IWorldOptions) {
        super(options);
        this.header= new Header();
        //initialize here other page object models
    }
}

Have in mind that in the feature file you can refer to the page object model created, using the same name that you set as public property in the src/custom-world/pageObjectWorld.ts

#Good
When i click on "header.logo"

#Bad
When i click on "Header.logo"
When i click on "#logo-id"

How to run the test

To run your tests locally just call the WDIO runner:

$ npm test:local

How to generate report

To generate the report after a test runs just call

$ npm test:report

Inside the folder report you'll find cucumber.html file that you can open to see the results.

Configurations

Environment-specific configurations

You can setup multiple configs for specific environments. Let's say you want to have a different baseUrl for your local and STG tests. Use the wdio.conf.ts to set all general configs (like mochaOpts) that don't change. They act as default values. For each different environment you can create a new config with the following name scheme:

wdio.<ENVIRONMENT>.conf.ts

Now you can create a specific config for your pre-deploy tests:

wdio.STG.conf.ts

var config = require("./wdio.conf.ts").config;

config.baseUrl = "http://staging.example.com";

exports.config = config;

Your environment-specific config file will get merged into the default config file and overwrites the values you set. To run a test in a specific environment just add the desired configuration file as the first parameter:

$ npm run wdio wdio.STAGING.conf.ts

Running single feature

Sometimes it's useful to only execute a single feature file, to do so use the following command:

$ npx wdio wdio.conf.ts --spec ./src/features/select.feature

Using tags

If you want to run only specific tests you can mark your features with tags. These tags will be placed before each feature like so:

@Tag
Feature: ...

To run only the tests with specific tag(s) use the --cucumberOpts.tagExpression= parameter like so:

$ npx wdio wdio.conf.ts --cucumberOpts.tagExpression='@Tag or @AnotherTag'

For more tag options please see the Cucumber.js documentation

Pending test

If you have failing or unimplemented tests you can mark them as "Pending" so they will get skipped.

// skip whole feature file
@Pending
Feature: ...

// only skip a single scenario
@Pending
Scenario: ...

Adding new steps and snippets

The predefined snippets allow you to do a lot of common things but you might need extra snippets which are better aligned with your aims. To do so you will find all step definitions in ./src/steps. They are separated in given, when and then.

You define your snippet using regular expressions. This is pretty powerful as it allows you to create complex sentences with multiple options. Everything that's within "([^"]*)?" gets captured and appended to the callback. The last argument is always a callback function that you need to call when your step is done. You can access the browser and your WebdriverIO instance with browser.

To assert values this boilerplate project uses WebdriverIOs embedded assertion library called expect-webdriverio.

Comments

You can add additional descriptive comments in your feature files.

###
  This is a
  block comment
###
Feature: As a bystander
    I can watch bottles falling from a wall
    So that I can be mildly amused

# This is a single line comment
Scenario: check if username is present
    Given I login as "roboter" with password "test123"
    Then the username "roboter" should be present in the header
