Introduction to Splinter - Awaiting Input in Javascript

Splinter is a testing tool for web applications that allows you to automate browser actions in Python or Javascript. It uses the underlying automation libraries such as Selenium and WebDriver, but provides a more user-friendly and intuitive API for testing.

One of the key features of Splinter is the ability to wait for user inputs before proceeding with the next action. This is essential for applications that have dynamic elements or require user interaction to proceed. In this tutorial, we will explore how to use Splinter to wait for user inputs in Javascript.

Installation

Splinter can be installed using NPM (Node Package Manager). Open your terminal and run the following command:

npm install splinter

Next, you will need to install a webdriver. Splinter supports several webdrivers including Chrome, Firefox, and PhantomJS. For this tutorial, we will use the Chrome webdriver. You can install it using the following command:

npm install chromedriver

Usage

Once you have installed Splinter and the required webdriver, you can start using it in your Javascript code. Here's an example of how to use Splinter to wait for user inputs:

const { Builder } = require('splinter');

(async () => {
  const browser = await new Builder()
    .forBrowser('chrome')
    .build();

  await browser.get('https://example.com');

  const inputField = await browser.waitFor('#input-field');

  await inputField.sendKeys('Hello World!');

  await browser.quit();
})();

In the example above, we first create a new instance of the Builder class and specify the webdriver to use (in this case, Chrome). We then navigate to a webpage and wait for an input field with the ID #input-field to load. Once the input field is available, we simulate user input by sending the string 'Hello World!'. Finally, we close the browser.

Conclusion

Splinter is an excellent tool for automating web application testing, and its ability to wait for user inputs makes it even more powerful. With its easy-to-use API and support for multiple webdrivers, Splinter is a great choice for both novice and expert developers.
