WebDriverIO – Get Alert Text
getAlertText():- getAlertText() command is used to get the available text present on Alert Box/Dialogue Box or on user prompt. If there is no Alert Box/Dialogue Box or user prompt, it returns an error.
Usage: – browser.getAlertText()
Pre-requisite: Have ‘Visual Studio Code’ IDE installed in your machine (Click here to install if not installed in your machine)
Here is the small Exercise to understand getAlertText Command by clicking on ClickToGetAlert button which generates an AlertBox and storing text present on that alert in a variable and printing it, using getAlertText command of WebDriverIO.
Using getAlertText() Command
First, I will demonstrate the exercise where we will open URL in browser window, then click on ClickToGetAlert Button which generates an Alert Box on Screen and then storing text available on Alert Box and print it using getAlertText command, followed by practically demonstrating the WebDriverIO Automation code for achieving it.
Exercise:-
1) Navigate to http://omayo.blogspot.com/ 
2) Clicking on ClickToGetAlert Button on Omayo.blogspot.com Web Application.
3) Storing Available Text “Hello” in a variable and printing it.
Practical Demonstration:
Following are the Steps to Perform above Exercise (i.e. To click on ClickToGetAlert Button which generates an Alert Box on Screen and then storing text available on Alert Box and print it using getAlertText() command) using WebDriverIO Automation code in ‘Visual Studio Code’ IDE:
Pre-requisite: Download the Project from here (Click here to Download) and Unzip it.
1) Open Visual Studio Code on your system.
2) Click on File and Select Open Folder. Select the project folder on which your workspace is present.
3) Expand ‘test’ from the Explorer, right click on the displayed ‘specs’ and select ‘New File’ option as shown below:
4) Give any name of the newly created file say “getAlertText_test.js” and copy the below given code into the newly created file as shown below and save the file:
The following is the WebDriverIO sample code to click on ClickToGetAlert Button to generate Alert Box on Screen and printing the text present on it on ‘Omayo.blogspot.com’ Web application.
You can understand this code, by reading the comments provided in the below code:
Copy the code from here:-
describe('This Example show usage of getAlertText() command in webdriverio', () => {
it('should display Text of Alert Box', ()=> {
browser.url('http://omayo.blogspot.com');
$('#alert1').click(); //Click on ClickToGetAlert Button
let AlertText = browser.getAlertText(); //Storing the text present on Alert/Dialogue Box
console.log(AlertText);
browser.pause(3000);
});
});
5) Click on ‘wdio.conf.js’ to open in the IDE, and make sure the Test file name is updated properly in this file as shown below and save it:
6) Click on Terminal and Open New Terminal. 
7) By Default, Powershell Terminal will open, change it to git bash as shown below:
8) Open Another Terminal in the same way we did in the step 6 and run below command in terminal
.\node_modules\.bin\wdio .\wdio.conf.js
Observe that the ‘getAlertText _test.js’ will get executed successfully, the firefox Browser will launch, and open URL given in code and respective action will be taken by WebDriverIO Automation code.
And also, the result will be displayed as ‘Passed’ in the terminal as shown below:
This is how, we can take help of getAlertText() Command of WebDriverIO to store text present on Alert Box which appears on screen. Likewise, I will explain other commands to perform different operations on Web Pages using WebDriverIO in the upcoming Articles .
