About identifying QT dialogs

Post by theselby » Thu Sep 27, 2018 1:26 pm

Hello,

I've run into weird scenarios trying to figure out how to automate a QT app.
On my developer machine it works to automate the app. However, when I use the app on another computer, it doesn't work anymore.

Are there any best practices regarding QT that I should take care of, in order to make it always-work ?

Hi,

Could you please post exact error message you are getting? Also, please post a Ranorex snapshot (NOT screenshot!) of the problematic element, ideally, taken on both machines, so we can see the difference. And don't forget to post the xpath, which works on one system, but fails on another. Thanks.

Its pretty similar on the other machine, only the IDs are different
Also I manually changed the paths to be a little more specific, as in the following:
"/form[@title='JasminCam' and @processname='JCam-main' and @appname='JasminCam']/text[@name='mPasswordTxt']"

In code I do something like this:

Code: Select all

Stopwatch sw = new Stopwatch();
                
                Boolean found = false;
                sw.Start();

                while (!found)
                {
                    // here i try validating the existance of the app
                    found = Ranorex.Validate.Exists(@"/form[@title='JasminCam' and @processname='JCam-main' and @appname='JasminCam']", 
                        "Check for dialog existance... 'JasminCam'", false);

                    if (sw.Elapsed.TotalSeconds > 10)
                        break;
                }


                Boolean did = false;

                if (!did)
                {
                    MyTestProject.JasminCamV4 jsm = MyTestProject.JasminCamV4.Instance;
                    e.Result = false;
                    jsm.Login.SelfInfo.WaitForExists(new Ranorex.Duration(30 * 1000));

                    try
                    {
                        if (jsm.Login != null && jsm.Login.MPasswordTxt != null)
                        {
                            jsm.Login.MPasswordTxt.EnsureVisible();
                            jsm.Login.MPasswordTxt.TextValue = site.Password;
                            e.Result = true;
                            did = true;
                        }
                    }
                    catch (Exception ex)
                    {
                        e.Result = ex.Message;
                    }
                }

                // try the other file
                if (!did)
                {
                    MyTestProject.JasminCam_Win7 jsm = MyTestProject.JasminCam_Win7.Instance;
                    e.Result = false;
                    jsm.Login.SelfInfo.WaitForExists(new Ranorex.Duration(30 * 1000));

                    try
                    {
                        if (jsm.Login != null && jsm.Login.MPasswordTxt != null)
                        {
                            jsm.Login.MPasswordTxt.EnsureVisible();
                            jsm.Login.MPasswordTxt.TextValue = site.Password;
                            e.Result = true;
                            did = true;
                        }
                    }
                    catch (Exception ex)
                    {
                        e.Result = ex.Message;
                    }
                }

There are no errors reported. However, it behaves like its not finding the QT app/dialog and/or element.

Hi,

Please post the snapshot from both machines. If the ids are different on both machines, then you need to make the xpaths resistent to these changes. Unfortunately, without seeing, at very least, Ranorex snapshot (from both systems), there is no way anyone here can suggest better xpaths. Thanks.

Attached files to this reply.

Later Edit:
I added some debug logs on the runtime machine:

No element found for path '/form[@name='Login' and @processname='JCam-main']' within 10s.

No element found for path '/form[@name='Login' and @processname='JCam-main']/text[@name='mPasswordTxt']' within 5s.

No element found for path '/form[@title='JasminCam' and @processname='JCam-main' and @appname='JasminCam']/text[@name='mPasswordTxt']' within 5s.

Hi,

The first problem I see is, that you are using different versions of Ranorex on both machines! You must use the same Ranorex version everywhere, otherwise, the results could be different:
RanorexVersion.png
RanorexVersion.png (18.22 KiB) Viewed 57 times
As you can see, newer version of Ranorex (installed on Win7 machine) shows significantly more details about QT elements. There is a note in 8.2.1 release notes, that there is added support for QT tooltips. But it may be that they generally improved QT support?

Additionally, because you are using different versions of Windows, you will most probably have to optimize the xpaths on both systems. There is no way around. You see, things could look and behave differently on various systems. So if using the same Ranorex version on all systems does not fix your problem, you will have to find common xpaths, which will work on all systems.

BTW, make sure there is installed the same version of tested app on all systems and that there are installed the same versions of QT libs, .net and VC++ redistributable libs. Using the same versions of everything is essential for successful automation!

Hey there,

Thanks for all the assistance.
Meanwhile I also discovered myself that I did something wrong when deploying the app:
1. i didn't had all vc++ redistributables installed
2. as of the runtimes... i only copied the DLL files, but forgot to also copy the subfolders

Doing the 2 points above, made it work. Many thanks
