It took me a while to figure out how to get Selenium IDE to click a link, wait for the new tab's page-load to settle down, and validate the URL of the new page, but I did it.

Overall, I'm pretty satisfied with Selenium IDE. If you have business processes that involve visiting a web site and clicking around a bunch to "make sure everything looks good," it's a nifty tool for pretending to be yourself, only sped up really really fast.

Steps

The one and only test present in this Selenium IDE project runs through 8 steps:

Open the Katie Kodes page on Ko-Fi
- Command: open
- Target: katiekodes (on top of a test base URL of https://ko-fi.com/)
Click the Katie Kodes blog link
- Command: click
- Modify new window configuration -> New Window Configuration Enabled: checked, Window Name: blog_new_tab, Timeout: 2000, click "Confirm"
- Target: xpath=(//a[@target="_blank" and contains(@href, "katiekodes.com")])[1]
Close the original Ko-Fi tab
- Command: close
Make sure we are viewing the new blog tab
- Command: select window
- Target: handle=${blog_new_tab}
Wait for something bloggey to be on the screen
- Command: wait for element present
- Target: xpath=(//a[contains(@href, "ko-fi.com")])[1]
- Value: 30000
- (Technically, this isn't required for this example, but the situation I was dealing with opened a new tab and then handed off cookies through about 4 different URLs before settling down on one, so I decided to validate that things were "all done" by looking for a weird, distinctive HTML element I knew only existed in the final, settled page.)
Save the blog URL to a variable
- Command: execute script
- Target: return document.URL;
- Value: theurl
Assert that the blog URL is correct
- Command: assert
- Target: theurl
- Value: https://katiekodes.com/
Close the web browser
- Command: close

Code

To try it yourself, save this code as Selenium Demo.side on your computer and open it as a project with the Selenium IDE browser plugin, then click the "Validate the new-tab URL" test and click "Run current test."
