Clearing Cache

[Amardeep]

HI,

I am currently writing a test case to open the browser and select a database in the application. When I run the test first time it put the vale in the textboxes and then select the database.

But runnig the test second time the value selected in previous run is there and my test fails. Is there a way where the test is run every time from the start irrespective what has been run previously. I guess there should be some way to cleanup the test which is ran previosly. 

Thanks
Amar

Quick search looks like you can clear temp files, cookies, and history using the ArtOfTest framework.  Place in your before/cleanup section.

Hope that helps!

Thanks,

I tried to use it in TestCleanup but I am getting error:  "object reference not set to an instance of an object"


        [TestCleanup()]
        public void MyTestCleanup()
        {

            //
            // Place any additional cleanup here
            //

            #region WebAii CleanUp
          
            // Shuts down WebAii manager and closes all browsers currently running
            // after each test. This call is ignored if recycleBrowser is set
            Initialize();
            ActiveBrowser.ClearCache(ArtOfTest.WebAii.Core.BrowserCacheType.Cookies);
            ActiveBrowser.ClearCache(ArtOfTest.WebAii.Core.BrowserCacheType.History);
            ActiveBrowser.ClearCache(ArtOfTest.WebAii.Core.BrowserCacheType.TempFilesCache);
            this.CleanUp();

            #endregion
        }

Hi Amardeep,

Thank you for contacting us.

The code you are using is absolutely correct and it should clear all these types of cache.

Where do you receive the exception (what row)? Please send us the entire trace log so we can investigate further.

Hope to hear from you soo.

Hi,

The error is coming on the second row of the TestCleasnUp class :
  ActiveBrowser.ClearCache(ArtOfTest.WebAii.Core.BrowserCacheType.Cookies);

Sorry i don't have the trace file yet.

Thanks
Amar

It appears you are trying to delete cookies , I vaguely remember running into this problem, I think I was successful with CookiesManager.DeleteCookie(url) method . I hope this helps!

Hi All,

I found this code on the net and it works fine:

//Temporary Internet Files

System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 8")

//Cookies()

System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 2")

//History()

System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 1")

//Form(Data)

System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 16")

//Passwords

System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 32")

//Delete(All)

System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 255")

//Delete All – Also delete files and settings stored by add-ons

System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 4351")
