Out of memory during repository generation

[LeonP]

I am working with large data tables and was building a repository column by column (each column is a large data table).

I was already limiting the repository to only 3 columns, but still got this out of memory exception.
For earlier trials I let Ranorex decide which repository elements to include while capturing a manual test, but this resulted in items that I needed to reference in user code missing from the repository.

Can this be fixed?

Thanks,

Leon

How you you add items to the repository? Using the "Add to Repository (incl. children)" context menu entry?
How many elements are you trying to add and how many items are in your repository already?

BTW you don't need to have every element in the repository. For example, if you want to iterate through all cells of a table, it's much easier to only add the table element to the repository and then use the "Columns" and "Rows" properties of the table element to iterate through columns/rows and their cells.

A similar approach is creating a repository element that corresponds to all rows and then use the RepoItemInfo.CreateAdapters method to get all the corresponding elements at once.

Alex,

Thanks for the suggestions.

Yes, I was using the "Add to Repository (incl. children)" context menu entry, but only for the part of the UI which displays several tables. I am comparing/trialing a few test tools and the fact that Ranorex reads in both the visible and non-visible part of the table caught me by surprise. The tables I need to access are all ComponentOne elements with MSAA enabled.

Ranorex recognizes the tables as "ContainerDeltaGrid" which does not have "Rows" or "Column" properties.

I must admit I do not have the level of sophistication at this point to try RepoItemInfo.CreateAdapters.

I would appreciate if you could point me to more detailed information to solve this problem. I am impressed with the capabilities of Ranorex, but since ComponentOne grid access is the main part of the UIs I need to test, QTP from HP is the winner.

I would appreciate if you could point me to more detailed information to solve this problem.

First I need to know what you are trying to do with the tables. For example, you want to iterate all cells, you want to interact with only one single cell, ...

And a Ranorex snapshot of the application would be a nice help, too. Just attach the Ranorex snapshot to your post or send it directly to support_at_ranorex.com if you don't want to make it available in the forum. See the following section in the Ranorex User Guide on how to create Ranorex snapshots:

Alex,

I can not sent a snapshot for proprietary reasons, but I think the info below will help.

The screen looks like a simple spreadsheet table with 8 columns and 250 rows of decimal numbers. 40 rows are visible in the user interface.

I learned to drag and drop individual rows from the element browser into the repository.
This is sufficient to capture a manual test where individual cells are selected and subsequently, values in pop-up windows are verified.

The type of test I need to implement goes as follows:
1. read the content of a specific cell or cells in the table
2. based on the value read and some information external to the table, determine the row and column number of the next cell to read
3. read and verify the value in the cell at this calculated address (in row,col format)

Outside information can change, resulting in different rows/cells needing to be examined.

I am used to having indexes available over the visible range.
The fixed names (e.g. CellRow_57_Column_1) are not helpfull.

I included part of the repository.cs file that was generated by Ranorex.
The dataGrid refered to in the repository is a C1FlexGrid from ComponentOne.


Thanks,
Leon

Hi Leon,
I would suggest you watch the Ranorex screen casts for RanoreXpath 1 & 2 at http://www.ranorex.com/support/screencasts.html

This will instruct you on how to craft custom XPaths to find the other cells, rows, columns etc... based on the information you determine from your inputs. These screen casts are very useful and (like they did for me) can help open your eyes to more of the power that Ranorex gives us.

Hi,

the code of your test you need to implement may look something like this:

// get the cell after the current cell
Cell following_cell = repo.<yourDataGrid>.current_cell.GetPath().ToString() 
	+ "/following-sibling::cell";

// extract the row and the column out of the previously found cell
int row = /*<string function to get the row out of the cell following_cell>*/;
int col = /*<string function to get the column out of the cell following_cell>*/;

// get the cell which is referenced in previously found cell,
// either building a RanoreXPath 
Cell referenced_cell = repo.<yourDatagrid>.GetPath().ToString() 
	+ "/row[@accessiblename='Row "
	+ row.ToString() + "]/cell[@accessiblename='Row " 
	+ row.ToString()  + " Column " + col.ToString() + "]'";
// or accessing the tables structure
Cell referenced cell = repo.<yourDataGrid>.Rows[row].Cells[col];

To learn more about the RanoreXPath have a look at following links:

Thanks!

To address my initial problem of running out of memory, I was able to use the xpath in the element browser to select a subset of the container elements and only move those to the repository. (each of the three containers I need in the repository represents >2K objects).

The code snippets are useful. Because I am working with a third party UI component (ComponentOne) I can only use the text string editing version, not the indexing.

Thanks to all for your suggestions.
