Refreshing the Page After Executing a JavaScript Command

Overview

In certain testing scenarios, you may need to execute a JavaScript command directly in the browser's console to set up a specific state, such as mocking data using sessionStorage. After executing the command, a page refresh is often required for the application to recognize and apply the changes. This guide outlines the recommended method for achieving this within a test case.

How It Works

To reliably execute a script and then refresh the page, use a Navigate action. This method is more explicit and reliable than a standard page initialization action for this purpose.

  1. Store the Command (Optional): For better management, you can use a Set Variable action to store your JavaScript command as a string. For example: sessionStorage.setItem('alightTestingInstructions', '{ "mocks": { "mockAll": false, "mockResources": [ { "resource": "balancehistory", "scenario": "singlePlan" }]}}');
  2. Execute the Script: Add an action to execute the JavaScript command in the browser's console.
  3. Add a Navigate Action: Immediately following the script execution, add a Navigate action to your test.
  4. Set the Navigation URL: In the URL input field for the Navigate action, enter the JavaScript snippet: location.href.

Using location.href as the navigation destination instructs the browser to reload its current URL. This forces a full refresh, ensuring that any changes made by the console command are applied as the page re-initializes.

Limitations

This method effectively triggers a page refresh, but test execution can still be affected by the application's performance. If the page gets stuck in a loading state after the refresh, it may indicate an intermittent issue with the application under test rather than a flaw in the test logic. It is recommended to investigate such performance issues with your development team.
