2. Sign up to BrowserStack

To execute the cross browser testing, with BrowserStack and sign in.

Once you are in, you will be directed to the dashboard page. Each user will be impute a unique User Name and Access Key. We will be using them in our tests to connect to the BrowserStack server.

3. Configuration

To configure the BrowserStack accession key, set theuser and keyvalue in thewdio.config.jsfile. Also set inbrowserstackLocal: trueto route the connections from your local computer to the BrowserStack cloud.

exports.config = {user: process.env.BROWSERSTACK_USERNAME, Key: process.env.BROWSERSTACK_ACCESS_KEY, services: [['browserstack ', {browserstackLocal: true}]],}

Writing and executing tests in BrowserStack with WebdriverIO

Let ’ s indite a bare test to fulfill them in BrowserStack. In the examination, we are navigating tohttps: //bstackdemo.com/and passing in the certification, and validating the success message.

describe (`` First Test '', async () = & gt; {it (`` Execute the tests in different browser '', async () = & gt; {await browser.url ('https: //bstackdemo.com '); // bestow the first product to drag const firstProduct = await browser. $ (`` //div [@ id= ' 1 '] //div [@ class='shelf-item__buy-btn '] [normalize-space () ='Add to haul '] ''); await firstProduct.click (); // chatter on the check button const checkOutButton = await browser. $ (`` //div [@ class='buy-btn '] ''); await checkOutButton.click (); await expect (browser) .toHaveUrlContaining ('checkout '); // pass the username value const username = await browser. $ (`` # username ''); await username.click (); await browser. $ ('// * [@ id= '' username ''] /div [2] ') .click (); // pass the watchword value const password = await browser. $ (`` # password ''); await password.click (); await browser. $ ('// * [@ id= '' password ''] /div [2] ') .click (); // click on the login button await browser. $ (' # login-btn ') .click (); // fill the first name const firstName = await browser. $ (' # firstNameInput '); await firstName.setValue (`` Test ''); // occupy the terminal name const lastName = await browser. $ (' # lastNameInput '); look lastName.setValue (`` User ''); // fill the address const address = await browser. $ (' # addressLine1Input '); await address.setValue (`` 12, ABC apartment ''); // fill the province const province = await browser. $ (' # provinceInput '); await province.setValue (`` TN ''); // occupy the postal code const postalCode = await browser. $ (' # postCodeInput '); look postalCode.setValue (`` 123456 ''); // clicking on the sumbit button await browser. $ (' # checkout-shipping-continue ') .click (); const confirmationMessage = $ (' # confirmation-message ') await expect (confirmationMessage) .toHaveText ('Your Order has been successfully placed. ');});});

To run the examination case, surpass the below command.

npm run wdio

Once you run the exam cases, WebdriverIO will interact with the BrowserStack cloud and will execute the tests. After the test run, you can see the result in the BrowserStack splasher.

Running WebDriverIO Tests in Different Browsers

To run the tests in different browser, you have to in thewdio.config.jsfile. It is possible to run the tests in different browser constellation with BrowserStack. Under capabilities, surpass the browser configuration as an array. We can also define the different browser versions that we indent to run in the capabilities by passing the version name.

capabilities: [{browserName: `` chrome '', acceptInsecureCerts: true,}, {browserName: `` firefox '', acceptInsecureCerts: true,}, {browserName: `` safari '', acceptInsecureCerts: true,},],

Once you run the test in different browsers, you can view the results in the BrowserStack dashboard. Below is the sample test report attached.

WebdriverIO also gives us the description of running the tests in the depot.
