WaitAliasChild does indeed always return immediately.
Your statement "Property Exists will return immediately" is, however, incorrect (At least in my case)
It will ONLY return immediately if the element is visible.
If it's invisible, it will wait for the default timeout
WRT the enclosing of an if statement - yeah, in production code, I would indeed do that. For the sample code, however, I KNEW whether it would return true or false, I just did it that way to keep the sample code shorter
Using TC v15.55.53.7, here's a small example based on the website https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_style_visibility
It returns immediately
Isn't that a web app? My AUT is Java, so does not seem like a representative test
RefreshMappingInfo() makes it worse. It causes the waitAliasChild() to wait as well.
Here is proof that the issue is nothing to do with a quirk of the AUT.
Example Java App:
package com.example;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class App extends JPanel implements ActionListener {
private static JFrame childFrame;
private static boolean secondFrameVisible = false;
public App() {
childFrame = new JFrame("Child Window");
childFrame.setName("Child Frame");
JLabel childLabel = new JLabel("This is a child frame");
childLabel.setPreferredSize(new Dimension(400, 400));
childFrame.getContentPane().add(childLabel);
childFrame.pack();
toggleSecondFrameVisibility();
JButton toggleButton = new JButton("Toggle visibility");
toggleButton.setActionCommand("vis");
toggleButton.addActionListener(this);
add(toggleButton);
}
private static void createAndShowGUI() {
JFrame frame = new JFrame("FrameDemo");
frame.setName("Main Frame");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(new App());
frame.pack();
frame.setVisible(true);
}
@Override
public void actionPerformed(ActionEvent e) {
toggleSecondFrameVisibility();
}
private static void toggleSecondFrameVisibility(){
secondFrameVisible = !secondFrameVisible;
childFrame.setVisible(secondFrameVisible);
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
}It looks like this - a main window ("FrameDemo") with a child window ("Child Window").
When you click the "Toggle Visibility" button in the main window, the Child Window is set to invisible.
Then create a Javascript project in TestComplete, add the following code to script Unit1:
function debugme(){
Aliases.javaw.WaitAliasChild("Child_Frame").Exists; // <-- set breakpoint here
Aliases.javaw.WaitAliasChild("Child_Frame").Exists; // <-- set breakpoint here
Aliases.javaw.WaitAliasChild("Child_Frame").Exists; // <-- set breakpoint here
Aliases.javaw.WaitAliasChild("Child_Frame").Exists; // <-- set breakpoint here
}
I'm not able to reproduce your issue. If I run the following code against a new project,
function main()
{
Log.Message("Start");
var mf = Aliases.java.WaitAliasChild("Main_Frame")
if (mf.Exists) {
Log.Message(mf.Exists);
Log.Message(mf.Visible);
}
var cf = Aliases.java.WaitAliasChild("Child_Frame");
if (cf.Exists) {
Log.Message(cf.Exists);
Log.Message(cf.Visible);
}
Log.Message("Finish");
}the following output is shown,
Main window visible and Child window visibleMain window visible and Child window invisibleNotice the time differences, it's not waiting X number of seconds.
What version of TC are you using?
By the way, your instructions were perfect. Thanks!
TC version is 15.65.12.6 x64
Looking at your screenshots, I guess what you are showing is the "Time Diff" column? Showing that there is no wait?
function debugme(){
Log.Message("Start");
var cf = Aliases.javaw.WaitAliasChild("Child_Frame");
Log.Message("Checking exists");
let w = cf.Exists
Log.Message("Finish");
}As you can see, when it's not visible, it waits 10 seconds
