titleAS - Failure to get dump

On iOS 9 and up (full control mode), at some scenarios, SeeTest may fail to perform actions( i.e open object-spy ) on a page that contains a very large number of elements,

In order to resolve this issue you can use one of the following methods:

  • Node-based dump (recommendrecommended).

  • Set Dump parametersdump parameters.

  • Dump by UIElements only.
  • Dump by grid sampling.

Node-based dump

This ability should be configured per application using its bundle identifier.


  1. Open the "" found here.
  2. Add the line: 


     <bundle identifier>=ios.non-instrumented.dump.node-based.bundle

    For example, application with bundle identifier 'com.experitest.eribank' will add the line:



  3. Restart SeeTest.

  4. Deleting the line from the "" file will use the default dump on the application. 


By default, the Safari application bundle identifier is found at the "" file.


If the Node-based dump method did not work you can use this method to define a specific dump parameters to limit the element's numbers.


  • Depth - Define the depth of the element hierarchy tree.

  • Total - Define the total amount of elements in the dump.

  • Children - For each element (node) what are the max nodes successors node's successors (children).

To use this method you will need to add to the file the property: ios.non-instrumented.dump.parameters= <depth>,<total>,<children> for example:



You can use this property in run-time (for specific tests) by using the command: setProperty() with the property ios.non-instrumented.dump.parameters for example:


client.setProperty("ios.non-instrumented.dump.parameters", "20,1000,50");

Improvements in the non-instrumented dump

From STA 10.3 the 'Class' property has changed and now is more informative. 

To go back to the older dump - add to the file the property: 'xcelement.type.include=false'

Dump by UIElements only :

Create dump by collecting native UI elements. This can help to avoid crashes in case of large web dump.

to use this method, add to file the following property:

ios.dump.uielements.only_<bundleId>=<fetch.web.anchor=true/false> - for a specific application.

ios.dump.uielements.only.params=<fetch.web.anchor=true/false> - for all applications.

fetch.web.anchor: when set to true, we collect few extra non UIElements to be able to identify web elements.

Dump by grid sampling :

Create dump by sampling grid of points, SamplesX refers to how many samples on X-Axis when a device is in portrait orientation when in Landscape the samples on each axis will switch.

We recommend try first default value which is 5,12,5,true,false and if it does not create the expected dump only then try other values.

to use this method add to the following property:


optional parameters:
Hybrid: combines the grid sampling and the traditional dump method, which can improve performance.
FrontMostAppFocused: ignore results from elements that belong to another pids, such widgets, _UIRemoteView elements, and other apps.
