### WebdriverIO-v8 boilerplate code with Mocha BDD

This repository contains a collection of sample webdriverIO (v8) projects and libraries that demonstrate how to use the tool and develop automation script using the Mochajs BDD framework. It uses the `chromedriver` NPM package that wraps the ChromeDriver for you. This service does not require a Selenium server, but uses ChromeDriver to communicate with the browser directly.

This boilerplate code support Typescript, also provides sample utilities to read data from MS-Excel, executes SQL statements to any database (RDBMS such as Oracle, TeraData, MySQL, Vertica) for end to end testing. It generate Allure, JSON, Junit/Xunit, Spec reporters as well. `Please note that at the time of writing (January 2023) the wdio reporting module of JSON, Junit/Xunit are not fully compatible with V8 hence it is disabled from this boilerplate code.`

💡 If you need the wdio-v7 boilerplate project, please take the code from v7 branch: click [here](https://github.com/amiya-pattnaik/webdriverIO-with-mochaBDD/tree/wdio-v7)

### Installation
This project is tested on **Node v18.0.0** and above.  While earlier versions of node may be compatible, but they have not been verified.

`Node.JS:` Install  from the site - https://nodejs.org/en/  take the LTS version based on your Operating system. Please make sure you install NodeJS globally.

`JDK:` It is optional, install JDK and make sure class path is set properly. JAVA is require to start `Selenium Server` on your local environment nothing else.

### Selenium Tests / Appium Tests

To run your test you must have Selenium / Appium server up and running to execute any webdriverIO tests, or it will fail fast with an error. To start selenium automatically it has been added as part of `services: ['selenium-standalone']` and `services: ['appium']` in the *.conf.ts.  That's all there is to it.!.

### Run Some Sample Tests

To execute the entire test suite on local development or cloud provider, you can use below

Option 1: Local Environment `npm run test-local`.

Option 2: You can also run in `SauceLabs` or  `BrowserStack` or `LambdaTest` using `npm run test-sauce` or `npm run test-browserstack` or `npm run test-browserstack`.

Option 3: Mobile Device. To execute tests on mobile device use : `npm run test-mobile`.

💡 Before running mobile tests, perform the requisite Appium setup. For hassle free `one click Appium setup on OSX` refer [appium-setup-made-easy-OSX](https://github.com/amiya-pattnaik/appium-setup-made-easy-OSX) or refer [Appium Docs](http://appium.io/getting-started.html?lang=en)

### Config Files

WebdriverIO uses configuration files to setup and execute tests in specific ways.  The configuration is fully customizable, and different functions can be invoked before, during and after each test or test suite.  Config files are found in the `the root directory of this boilerplate project.`and all ends with `*.conf.ts`.  These can be called via the the cli.

### SauceLabs / BrowserStack / LambdaTest Integration

`SauceLabs`, `BrowserStack` and `lambdatest` specific code has been added in the `wdio.sauce.conf.ts`, `wdio.browserstack.conf.ts` and `wdio.lambdatest.conf.ts` under the /test/config folder. You just need to provide your SauceLabs/BrowserStack/LambdaTest credentials in the config file. To run test on SauceLabs, execute command `npm run test-sauce` to run test on BrowserStack `npm run test-browserstack`, to run test on LambdaTest `npm run test-lambdatest`.

### Logs

Complete set of execution `logs` will be generated during the run time and can be found in the parent folder location /logs.

### Reporters

WebdriverIO uses several different types of test reporters to communicate pass/failure.

##### Allure

The Allure Reporter creates [Allure](https://docs.qameta.io/allure/) test reports which is an HTML generated website with all necessary information to debug your test results and take a look on error screenshots. Add allure to the reporters array in config file and define the output directory of the allure reports.  Please note, this has been added in wdio.shared.config.

To generate and view an Allure report inside your corp network or locally, run `npm run allure-report`. The Allure report is hosted on a `web server` and can be accessed through http://YourMachineIP:5050/ and also generated locally which can be found at `./allure-report/index.html`. A typical Allure report will look like this.

##### Junit/Xunit

A WebdriverIO reporter that creates Jenkins compatible XML based JUnit/Xunit reports. Add it to the reports array in the config file and define the directory where the .xml files should get stored. webdriverIO will create an xml file for each instance under test and the filename will contain the browser and OS. Please note, this has been added in wdio.shared.config.

To generate and view the Junit/Xunit report inside your corp network or locally, run `npm run xunit-report`.  The Junit/Xunit report is hosted on a `web server` and can be accessed through http://YourMachineIP:3000/ and also generated locally which can be found at `./xunit-report/xunit-report.html`. A typical Junit/Xunit report will look like this.

##### Dot

To use the dot reporter just add 'dot' to the reporters array in the config file. The dot reporter prints for each test spec a dot. If colors are enabled on your machine you will see three different colors for dots. Yellow dots mean that at least one browser has executed that spec. A green dot means all browser passed that spec and a red to means that at least one browser failed that spec. All config files have this turned on by default.

##### Spec

Test reporter, that prints detailed results to console.

### Develop automation scripts (for both desktop browser and mobile browser / app)

You can write test by using Mocha BDD framework. You can choose TypeScript / JavaScript based design pattern or ES6 based.

Refer complete [WebdriverIO v8 API](https://webdriver.io/docs/api) methods to write your automation tests.

#### Using Mocha JavaScript framework

Tests are written in the Mocha framework. More about Mocha can be found at  https://mochajs.org/

Sample tests are located in `*.specs.js` files in the `/test/specs/` directory. A typical test will look similar to this:
```
//example (pls refer to pageobject class and spec files)

//a test using async mode//

describe('Performing a search operation on Yahoo Page',  () =>  {
  it('Performing a search operation', async () =>  {
    await yahooPage.open();
    assert.equal(await browser.getTitle(), 'Yahoo Search - Web Search');
  });
});

```
### The Page Object Design Pattern

Within your web app's UI there are areas that your tests interact with. A Page Object simply models these as objects within the test code. This reduces the amount of duplicated code and means that if the UI changes, the fix need only be applied in one place. In other wards one of the challenges of writing test automation is keeping your [selectors] (classes, id's, or xpath's etc.) up to date with the latest version of your code.  The next challenge is to keep the code you write nice and [DRY] (Don't Repeat Yourself).  The page object pattern helps us accomplish this in one solution.  Instead of including our selectors in Spec file (in Mocha), we instead place them in a `<pagename>.ts` file where we can manage all these selectors and methods together. Your test file should only call the test methods.

You can also place reusable functions or logic inside of these pages and call them from your step files. The page object serves as a layer of abstraction between tests and code.  When A test fails, it fails on a individual step.  That step may call a selector that is no longer valid, but that selector may be used by many other steps.  By having a single source of truth of what the selector is supposed to be, fixing one selector on the page object could repair a number of failing tests that were affected by the same selector.

An object called `Page` will be created with the prototype model or by ES6 class pattern.  This ensures that every instance of a page object is exported as a stateless construct. Any any changes to that state are handled in the browser, rather than on the server.

It is preferable to separate page objects into individual files that end with `.page.ts`.  These will require the basic `page.ts` prototype construct / abstract class and create new objects for each individual page.

For more information on the implementation of `Page Object Design Pattern`, refer to the `/test/pageobjects` directory. A typical page class using ES6 syntax will look similar to this:

💡 If you want to use ES5 syntax, refer to the sample.page.js under util-examples.

```
import Page from './page';
class LoginPage extends Page {

/**
    * define elements
    */

get usernameInput()   { return $('//*[@name="username"]'); }
    get passwordInput()   { return $('//*[@name="password"]'); }
    get loginButton()     { return $('//button[contains(., "Login")]'); }

/**
     * define or overwrite page methods
     */
    async open() {
        await super.open('login')       //this will append `login` to the baseUrl to form complete URL
        //browser.pause(3000);
    }
    /**
     * your page specific methods
     */

async waitForloginPageToLoad() {
      if(!(await this.headerImage.isDisplayed())){
        await this.headerImage.waitForDisplayed(10000);
      }
    }

async login(username, password) {
      //this.waitForloginPageToLoad();
      await this.usernameInput.setValue(username);
      await this.passwordInput.setValue(password);
      await this.loginButton.click();
    }
}

export default new LoginPage()

```
### Additional Utilities (out of scope of this framework)

### Working with DataBase

A relational database is, simply, a database that stores related information across multiple tables and allows you to query information in more than one table at the same time. Your application under test displays data from these database. So when you are actually performing automation testing it is very likely that you need to verify the data between actual (which you got it from browser) Vs expected (which you will get it from the database by executing SQL statements on database). This can be done by below statements in your code.
```
//example of connection to Oracle DataBase

var  db   = require('node-any-jdbc');

cogfig = {
  libpath: './config/drivers/oracle/ojdbc7.jar',
  drivername: 'oracle.jdbc.driver.OracleDriver',
  url:  'jdbc:oracle:thin:QA/password123@//abc-test.corp.int:1527/stage1',
  // uri: 'jdbc:oracle:thin://abc-test.corp.int:1527/stage1',
  // user: 'QA',
  // password: 'password123',
};

//example of sample select query to fetch the result set

var sql = 'SELECT * FROM emp_info where emp_id = "1001"';
db.execute(cogfig, sql, function(results){
  console.log(results);
});

For trouble shooting and more information, please visit `node-any-jdbc` module which can be [found here](https://www.npmjs.com/package/node-any-jdbc)

Note: `node-any-jdbc` is NOT packaged under this project. If you need, you can install it and start using it right away. You can also find sample examples under /util-examples/database-example.js

```

### Working with MS-Excel

You can user MS-Excel and store your test data, expected data in an excel sheet. Tou can keeep any number of excel sheets you want and use below common methods to puull data from youe sheet to be use as part of testing.  Please note it only support .xlsx file format. For more information refer to the `common-utilities.js` and `util-examples`

```
//example of pulling data from MS-Excel

var  utl  = require('../utilities/common-utilities.js');
utl.excel_getTableRow(__dirname+'/sample.xlsx', 'info', 'emp_id', '101', function(results){
  // returns only one row based on the condition
  //console.log(results);
  //console.log(results.emp_id);
});

utl.excel_getTableRows(__dirname+'/sample.xlsx', 'address', function(results){
  // returns all rows of the specified sheet
  //console.log(results[1]);
  //then do what ever validation you to do withe results
});

utl.excel_getAllSheetData(__dirname+'/sample.xlsx', function(results){
  // returns all sheets data of a excel file
  //console.log(results);
  //then do what ever validation you to do withe results
});
```

### Common utilities

Refer to the common Javascript functions that provides clean, performant methods for manipulating objects, collections, MS-Excel utilities, DataBase utilities etc. Few sample code can be found in ./util-examples/

Use [Underscore.js](http://underscorejs.org/) already bundled inside the framework which provides over 100 functions that support both your favorite workaday functional helpers: map, filter, invoke — as well as more specialized goodies: function binding, javascript templating, creating quick indexes, deep equality testing, and so on.

## History

Industry is moving towards Node.js / JavaScript, Angularjs, Full-Stack world. WebdriverIO, a JavaScript binding wrapper for Selenium Webdriver, was originated by Camilo Tapia's initial Selenium project called WebdriverJS, which was the first Webdriver project on NPM. In 2014, the project was renamed WebdriverIO later on. This repository is a pre-configured version of webdriverIO meant to jump-start the process of writing new test automation or adding test automation to existing node.js applications.
