Can't get Jint when no script tag is included #28
Description
I am trying to get Jint engine from the javascript service. However, when there is no script tag with a body, GetJint method returns null. I can get Jint engine after adding a script dynamically or including a script tag with body at start. It can be tested with following method.
[TestMethod]
public async Task JintTest()
{
var cfg = Configuration.Default.WithJavaScript().WithDefaultLoader();
var svc = cfg.Services.OfType<ScriptingService>().FirstOrDefault(x => x.Engine.Type == "text/javascript");
var htmlEmpty = "<!doctype html><script type=\"text/javascript\"></script>";
var htmlNonEmpty = "<!doctype html><script type=\"text/javascript\">a=5</script>";
var document = await BrowsingContext.New(cfg).OpenAsync(m => m.Content(htmlNonEmpty));
Assert.IsNotNull(svc.Engine.GetJint(document), "Can't get Jint when the script tag is not empty");
document = await BrowsingContext.New(cfg).OpenAsync(m => m.Content(htmlEmpty));
Assert.IsNotNull(svc.Engine.GetJint(document), "Can't get Jint when the script tag is empty"); // Currently error is here
var script = document.CreateElement("script");
script.SetAttribute("type","text/javascript");
script.TextContent = "a=5";
document.Head.AppendChild(script);
Assert.IsNotNull(svc.Engine.GetJint(document), "Can't get Jint even after dynamically adding the script");
}
