Is it actually feasible to automate and interact with web elements in a NW.js exe app? I have created a JavaScript script to open and test it

A test case for nw.js can be found in the official NW.js documentation. The original test case is written in Python, but I attempted to recreate it in JavaScript. However, I encountered an error that made it difficult to interact with elements in the nw.exe application, which is similar to a browser.


    const {Builder, By} = require('selenium-webdriver');
    
    let driver = new Builder()
      .forBrowser('chrome')
      .build();

    try {
      await driver.get('src/views/index.html');

      // Attempting to find and interact with the input box element
      await driver.findElement(By.id("input")).sendKeys("San Francisco");
    } finally {
      await driver.sleep(1000);
      await driver.quit();
    }

When running the script above, I encountered the following error:


    SessionNotCreatedError: session not created: Chrome failed to start: exited normally.
    ...
    Error details here...
    ...

Any help would be greatly appreciated!

Answer №1

Include the nwapp parameter in the chrome.Options while specifying the path to the NW.js binary file. Ensure that the chromedriver binary is located in the same directory as well. Additionally, I have created a corresponding package.json and index.html.

In this scenario, assuming test.js, index.html, and package.json exist within the same directory:

/path/to/nw-test/index.html
/path/to/nw-test/package.json
/path/to/nw-test/test.py

test.js

const {Builder, By} = require('selenium-webdriver');

const chrome = require('selenium-webdriver/chrome');

options.addArguments([
    "nwapp=/path/to/nw/project"
]);

options.setChromeBinaryPath('/path/to/nw.exe');

async function openNwExe(){

    let driver = new Builder()

    .forBrowser('chrome')  

    .setChromeOptions(options)

    .build();

    try{

        await driver.findElement(By.id("input")).sendKeys("San Francisco");              

    }    

    finally{

        await driver.sleep(3000);

        await driver.quit();

      }

}

openNwExe(); //function call
