Troubleshooting Page.title() Issues in Playwright for Your electron-vue Project

When working on automated testing in an electron-vue project, developers often run into specific issues that can hinder their test results. One common problem is when the Page.title() method returns an empty string, leaving you puzzled about the state of your application. In this guide, we will explore why this is happening and how to resolve it effectively.

The Problem: Empty Title Returned by Page.title()

In the context of an electron-vue application, retrieving the page title with Playwright may sometimes yield unexpected results. In this particular case, the developer ran the following code:

However, instead of getting the expected title "Splash," the console returned an empty string. This is a common predicament when the page hasn't fully loaded before the title is fetched.

Understanding the Solution

To resolve the empty title issue, we need to ensure that the page is fully loaded before we attempt to retrieve the title. Playwright provides a method called waitForLoadState() which can be utilized to wait for the page to load completely. Here's how you can implement this fix.

Steps to Fix:

Insert waitForLoadState():
Before retrieving the page title, we need to wait for the page to load completely. This can be accomplished by adding a single line to your test code.

Revised Code:
Here’s how the code looks after incorporating the solution:

Explanation of the Code

await electronApp.firstWindow();: This line gets the first window of your Electron app.

await page.waitForLoadState();: This crucial line waits for the page to completely load before any further actions are taken. It ensures all resources are finished loading, including any scripts that may set the page title.

Retrieving the Title: After ensuring the page has loaded, we can safely call await page.title() to capture the updated title.

Conclusion

Incorporating Playwright into your electron-vue project should enhance your testing capabilities, but issues like an empty title can arise if the application has not fully loaded. By adding await page.waitForLoadState(); to your test, you can easily resolve this issue and improve the reliability of your tests.

Make sure you implement this simple fix in your testing routines, and you should see a marked improvement in your results.

Happy testing!
