[Export-TC] Bad Request Error when exporting a lot of testcases from a search result

• Affected versions: 9.x, 10.x, 11.x, 12.x

Description

When exporting testcases from Search window,on clicking the export, one can get a bad request error as a result.

Steps to reproduce

0. Prepare a large number of "fake test cases" (so that their IDs are "large")

1. Navigate to the Test Case workspace

2. Click on magnifying glass to start a Search

3. Select pagination to 1000 (lower right corner)

4. Click on Export (upper right corner)

• In the browser, one should get now a "Bad request" error.
• In the SquashTM logs one should get the kind of messages diplayed in bad-request-logs.txt

Rationale

The URL is build concatenating the various IDs of the items in the search result , c.f.

Hence at some point, with "large IDs" and lots of test cases, one reaches some limit (it may be the URL max length and/or query parameter size)

How to validate the fix

Below are some thought. This might change with the actual implementation.

• One should still get the report when this worked (with a small number of selected TCs)
• The url (of the API call) to get the report should not display any list of IDS.
