chromeOptions is not the name of a known capability or extension capability

[rochacbruno]

I download and installed geckodriver

wget https://github.com/mozilla/geckodriver/releases/{latest}linux64.tar.gz
tar -xvzf geckodriver*
chmod +x geckodriver
geckodriver
(running on port 4444)

Used this code:

extern crate tokio;
extern crate futures;
extern crate fantoccini;

fn main() {
    use fantoccini::{Client, Locator};
    use futures::future::Future;
    let c = Client::new("http://localhost:4444");
   
    // let's set up the sequence of steps we want the browser to take
    tokio::run(
        c
            .map_err(|e| {
                unimplemented!("failed to connect to WebDriver: {:?}", e)
            })
            .and_then(|c| {
                // first, go to the Wikipedia page for Foobar
                c.goto("https://en.wikipedia.org/wiki/Foobar")
            })
            .and_then(|mut c| c.current_url().map(move |url| (c, url)))
            .and_then(|(mut c, url)| {
                assert_eq!(url.as_ref(), "https://en.wikipedia.org/wiki/Foobar");
                // click "Foo (disambiguation)"
                c.find(Locator::Css(".mw-disambig"))
            })
            .and_then(|e| e.click())
            .and_then(|mut c| {
                // click "Foo Lake"
                c.find(Locator::LinkText("Foo Lake"))
            })
            .and_then(|e| e.click())
            .and_then(|mut c| c.current_url())
            .and_then(|url| {
                assert_eq!(url.as_ref(), "https://en.wikipedia.org/wiki/Foo_Lake");
                Ok(())
            })
            .map_err(|e| {
                panic!("a WebDriver command failed: {:?}", e);
            })
    );
}

Same problem on nightly

[rochacbruno]

There is a different error when using WebKitWebDriver -p 4444

Ah, good catch! This is because WebDriver apparently now serializes legacy new session parameters incorrect (see b030fc3). I'd worked around that by setting this capability, but it's Google Chrome specific, and I'd left off the vendor prefix (fixed in 65081eb). I think this should now be fixed in the about-to-be-published 0.11.3!

[rochacbruno]

Thanks!

I used

[dependencies.fantoccini]
git = "https://github.com/jonhoo/fantoccini"
rev = "52cf5b1f763a5f19d3735bafd378fede9d193a07"

And now it works with geckodriver

ut using WebKitWebDriver -p 4444 it still fails with

thread 'thread 'tokio-runtime-worker-2tokio-runtime-worker-3' panicked at '' panicked at 'not yet implemented: failed to connect to WebDriver: SessionNotCreated(WebDriverError { error: SessionNotCreated, message: "Failed to match capabilities", stack: "", delete_session: false })called `Option::unwrap()` on a `None` value', ', src/main.rslibcore/option.rs::14355::1721

@jonhoo I'll give a talk on saturday about testing strategies and Iam going to show Factoccini demo!

Thanks

[jonhoo]

That's truly bizarre. As far as I can tell, we're hitting this line in WebKitWebDriver, but I don't see why the matched capabilities list would be empty. Can you try chromedriver instead?

[rochacbruno]

@jonhoo chromedriver works fine! thanks

Filed it as #37 :)
