Test Timeouts​

If you receive a timeout, it could come from the testing framework you are using, or from WebDriver. For example, if you use WebDriverIO with Mocha, there is a default timeout of 10 seconds.

Test Framework Timeouts​

Test framework timeouts can be resolved by increasing the timeout option specific to your test framework.

Here are some examples for WebDriverIO, which supports various testing frameworks:

WebDriverIO with Mocha Example:
// wdio.conf.js
exports.config = {
  framework: 'mocha',
  mochaOpts: {
    timeout: 90000
  },
  ...
}

WebDriver Timeouts​

WebDriver timeouts can be increased via the timeouts capability.

The following WebDriver timeout defaults are used:

capabilities = {
  ...
  timeouts: {
    script: 90000,
    pageLoad: 300000
  }
}

Additional information on WebDriver timeouts can be found here.

Can't Capture Snapshot with cropTo​

When using the Snapshot command, if you can't crop the target element with cropTo and the element isn't scrollable, you can use the scrollAndStitchScreenshot option. For example:

await browser.execute('/*@visual.snapshot*/', 'Home', { scrollAndStitchScreenshot: true });

Limitations​

If the target element is scrollable, the cropTo option may not capture a complete screenshot.
