How to use HTML elements from CEF

[lkitrossky]

Hi! I am building unit tests in CEF. Suppose, CEF browser opens some web page. Now I want to run some unit tests that will use HTML of the page. I succeeded to do it this way:

Code: Select all

class MyTestHandler : public TestHandler{
/*some lines*/
void OnLoadEnd(CefRefPtr<CefBrowser> browser,
                 CefRefPtr<CefFrame> frame,
                 int httpStatusCode) override {
             browser->GetMainFrame()->ExecuteJavaScript("document.getElementById('id').value = 'myvalue';", CefString(), 0);

My question is, may I reach and use HTML elements without JavaScript, some straight path to DOM from browser? I found something like

Code: Select all

browser->GetMainFrame()->VisitDOM...
CefRefPtr<CefDOMNode> docNode = document->GetDocument();


but cannot understand how to reach DOM object from browser or frame in OnLoadEnd or another. Thanks, LK

No, JavaScript is the way to go. You can also simulate mouse/keyboard input using the CefBrowserHost::Send*Event methods. Or use ChromeDriver: https://bitbucket.org/chromiumembedded/ ... eDriver.md

Thanks, but ExecuteJavaScript has no return value and we cannot know, if JavaScript code succeeded. Say, I need to click OK on some dialog box. How I to know that the dialog really closed? At least I need some way to enumerate DOM elements and check, if the dialog disappeared from the list. How can I do it?
Maybe can Chrome Driver you mentioned do the work? But it is a totally different direction needs Java, while I need unit tests from inside C++. Great thanks, Levi

ChromeDriver provides much of the functionality that you're looking for and can be used from different languages (Java, Python, Ruby, etc). If you want to do everything in C++ then you will need to write the test harness yourself. For more information on creating JavaScript/C++ bindings see https://bitbucket.org/chromiumembedded/ ... gration.md.

1. Can I use IPC to send message from renderer to browser that call browser->GetMainFrame()->ExecuteJavaScript succeeded nd DOM changed?
2. Suppose we use ChromeDriver: https://bitbucket.org/chromiumembedded/ ... eDriver.md. The reference you provided seems promising. Is there is a sample like you pointed to:

Code: Select all

WebElement searchBox = driver.findElement(By.name("q"));
       searchBox.sendKeys("ChromeDriver");

but in Python instead of Java?
Great thanks, Levi
