Mozilla's Gecko Marionette client in golang

What is Marionette

"Marionette is an automation driver for Mozilla's Gecko engine. It can remotely control either the UI, or the internal JavaScript of a Gecko platform, such as Firefox. It can control both the chrome (i.e. menus and functions) or the content (the webpage loaded inside the browsing context), giving a high level of control and ability to replicate user actions. In addition to performing actions on the browser, Marionette can also read the properties and attributes of the DOM.

If this sounds similar to Selenium/WebDriver then you're correct! Marionette shares much of the same ethos and API as Selenium/WebDriver, with additional commands to interact with Gecko's chrome interface. Its goal is to replicate what Selenium does for web content: to enable the tester to have the ability to send commands to remotely control a user agent."

Examples

Incomplete list. Check the tests for more examples.

Instantiate the client

client := NewClient()
// this are the default marionette values for hostname, and port 
client.Connect("", 0)
// let marionette generate the Session ID with it's default Capabilities
client.NewSession("", nil) 
	

Navigate to page

client.Navigate("http://www.google.com/")

Change Contexts

client.SetContext(Context(CHROME))
// or
client.SetContext(Context(CONTENT))
	

Find Element

element, err := client.FindElement(By(ID), "html-element-id-attribute")
if err != nil {
	// handle your errors
}

// else
println(element.Id())
println(element.Enabled())
println(element.Selected())
println(element.Displayed())
println(element.TagName())
println(element.Text())
println(element.Attribute("id"))
println(element.Property("id"))
println(element.CssValue("text-decoration"))
	
// width, height, x and y
rect, err := element.Rect()
if err != nil {
    // handle your errors
}

fmt.Printf("%#v", rect)
	
// size
w, h, err := element.Size()
if err != nil {
	// handle your errors
}

fmt.Printf("width: %f, height: %f", w, h)

//location
x, y, err := element.Location()
if err != nil {
    // handle your errors
}

fmt.Printf("x: %v, y: %v", x, y)

Find Elements

collection, err := element.FindElements(By(TAG_NAME), "li")
if err != nil {
	// handle your errors
}

// else
for var e := range collection {
	println(e.Id())
   	println(e.Enabled())
   	println(e.Selected())
   	println(e.Displayed())
   	println(e.TagName())
   	println(e.Text())
   	println(e.Attribute("id"))
   	println(e.CssValue("text-decoration"))
   	e.Click()
}

Execute JS Script

script := "function mySum(a, b) { return a + b; }; return mySum(arguments[0], arguments[1]);"
args := []int{1, 3} // arguments to be passed to the function
timeout := 1000     // milliseconds
sandbox := false    // new Sandbox
r, err := client.ExecuteScript(script, args, timeout, sandbox)
if err == nil {
    println(r.Value) // 4 
}

Wait(), Until() Expected condition is true.

client.Navigate("http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_get")

timeout := time.Duration(10) * time.Second
condition := ElementIsPresent(By(ID), "stackH")
ok, webElement, err := Wait(client).For(timeout).Until(condition)

if !ok {
	log.Printf("%#v", err)
	// do your error stuff
	return
}

// cool, we've the element, let's click on it!
webElement.Click()
