Adjust the duration of the script timeout in Selenium for JavaScript programming

Adjust the duration of the script timeout in Selenium for JavaScript programming

Currently, I am developing a function in JavaScript within the Selenium WebDriver framework to scroll on a website for a specific duration. The issue I am facing is that the default script timeout is approximately 15 seconds before it raises a ScriptTimeoutError. While there is ample information available on how to adjust this timeout in languages like Java with Selenium, documentation for the JS library is severely lacking.

To demonstrate the error, the test code below will trigger a ScriptTimeoutError after around 25 seconds:

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

async function example() {
  let driver = await new Builder().forBrowser("chrome").build();

  await driver.get("https://google.com");

  await driver.executeScript(`
  
  await new Promise((resolve) => setTimeout(resolve, 30000));
  
  `);
  console.log("DONE!");
}

example();

Below is the stack trace showing the ScriptTimeoutError:

After dedicating numerous hours to research, I stumbled upon the solution by pure chance. Within the WebDriver, there exists a function called manage(), which grants access to various useful functions for controlling the selenium server. Among these is setTimeout(), which accepts an object defining different timeouts for the webdriver (script, pageLoad, implicit). To set the timeout, an await statement must be used within an async function.

await driver.manage().setTimeouts({ script: 60000 });

The setTimeout function expects a JavaScript object to define timeouts:

 {
     implicit: time-in-milliseconds,
     pageLoad: time-in-milliseconds,
     script: time-in-milliseconds
}

Other handy functions available in the manage class:

Final Solution:

let webdriver = require("selenium-webdriver");

async function example() {
  // create driver
  let driver = await new webdriver.Builder().forBrowser("chrome").build();

  //   This function sets the script timeout to 60 seconds 
  //   Other timeouts can also be set using this function with an object:
  //   {
  //       implicit: TimeInMS,
  //       pageLoad: TimeInMS,
  //       script: TimeInMS
  //    }
  await driver.manage().setTimeouts({ script: 60000 });

  // This function retrieves the different timeouts for the selenium server
  //   { implicit: 0, pageLoad: 300000, script: 35000 }
  const timeouts = await driver.manage();
  console.log(timeouts);

  // Go to website
  await driver.get("https://bing.com");

  // Driver executes a script for 35 seconds
  await driver.executeScript(`
  
    await new Promise((resolve) => setTimeout(resolve, 35000));
  
  `);

  console.log("DONE!");
}

Answer №2

Consider running your script asynchronously by using driver.executeAsyncScript(). This way, you can ensure that it waits for the promise to be resolved before continuing. Additionally, if you have a short timeout threshold, you can set the script timeout using

driver.manage().timeouts().setScriptTimeout()

.

Keep in mind that setScriptTimeout() will specifically impact async scripts.
