ScriptVsNewWindow

Test cases for script injection when opening a new window and navigating to a URL (incl. POST navigation).

Expected Behavior

Common for all cases

The project loads an embedded web page with buttons and links. When any of them are clicked a new window should appear containing a WebView2 instance that:

1. Has scripts added (via a call to CoreWebView2.AddScriptToExecuteOnDocumentCreatedAsync).
2. This can be verified using the automatically opened DevTools window that should show the "script injected - before setting NewWindow" line in the console.

Script injection is expected to work with any value of the rel attribute of the <a> and <form> elements used to open the new window. I.e., it must not be required to set rel="noopener".

Case 1: Open Window From Javascript

The new window should display the DuckDuckGo search page.

Case 2: Open Window From Javascript without navigation

The new window should display a button (Open Tab1) and the text "This content is generated purely by javascript"

Case 3: Open Window From Target="_blank" (GET)

The new window should display the DuckDuckGo search page.

Case 4: Start open window test with POST navigation

The main window should display the Lite version of the DDG search page with a search box containing "test" and a Search button. The new window should display the search result page with actual results and the text box at the top should contain "test".

Actual Behavior

Case 1 and Case 2 are OK.

Case 3 and Case 4: the line "script injected - before setting NewWindow" is not shown, which means that script injection is not working.

Requirements

This project requires:

1. .NET6 SDK
2. WebView2 canary version. To test you need to install Edge Canary.
