Even in v8.3.0, this problem still persists. I do not understand why Katalon team leaves this fundamental/primitive BUG unfixed ---

Hi @kazurayam, We tried to reproduce the issue on both Windows 10 and MacOS 12.0.1. But the results are all the same: Renaming has no issue and the test case name is trimmed. Could you please record and send us the video of the error and the error log? Nam Nguyen. ---

I believe you haven’t tested a case where you have **subfolders** under the `Test Case`. Katalon Studio can not manages _subfolders_ under the `Test Cases` folder properly. Please follow the steps I described at > [@Script code vanished when a test case is renamed](http://forum.katalon.com/t/v8-3-0beta-script-code-vanished-when-test-case-is-renamed/63016): > > Katalon Studio v8.3.0.beta macOS Monterey 12.2.1 I created a GitHub project where you can see the bug reproduced. step1 I created a script [Test Case/sub/TC1](https://github.com/kazurayam/CodeVanishedWhenTestCaseRenamed/blob/step1/Scripts/sub/TC1/Script1646221324643.groovy), this had no problem step2 I moved the script to [Test Cases/sub/subsub/TC1](https://github.com/kazurayam/CodeVanishedWhenTestCaseRenamed/blob/step2/Scripts/sub/subsub/TC1/Script1646221324643.groovy), this had no problem step3 I renamed the script to [Test Cases/sub/subsub/Main](https://github.com/kazurayam/CodeVanishedWhenTestCaseRenamed/blob/step3/Scripts/sub/subsub/Main/Script1646222028338.groovy) step4 I renamed the script to Test Cases/sub/subsub/Test, Test Cases/sub/subsub/TestTest, Test Cases/sub/subsub/testesttest ---- and found that the script code has vanished.

A Katalon Studio project contains 2 folder corresponding to a single Test case: - `/Test Cases/sub/subsub/TC1.tc` - `/Scripts/sub/subsub/TC1/Scriptxxxxxxxxxx.groovy` Theoretically these 2 folders should be always in sync. But I found the `Script` folder goes out of sync when I rename/move a Test Case. I believe, KS has a bug here. ---

I just experienced this… and i’m sure now it explains why sometimes I felt like I was losing test scripts but wasn’t sure why. so I created about 10 test scripts and moved them to a different folder…tried to rename a few… after few hours when i came back, the codes were deleted…just left with empty test cases. i was able to retrieve some of them by going to Git and commit and checking the differences… before had code, after was null. This is a critical issue and not something that should be in production system. Why is this issue not resolved? It’s been reported so many times. ---

I found a way to reproduce this problem, which has been left open over 4 years! See > [@Katalon Studio erased a Test Case code when it was moved, and then renamed](http://forum.katalon.com/t/katalon-studio-erased-a-test-case-code-when-it-is-moved-and-renamed/84169/): > > This post follows my previous post: I believe that I have found out a procedure how to reproduce the incident (Test Case code is erased by Katalon Studio). So I would explain it here. I used 2 machine environments. The issue was reproduced on both. MacOS12.6 + Katalon Studio 8.3.0 Windows 10 + Katalon Studio Standard Editon 8.4.1 I did: Create a new Katalon Project Create a new Test Case at Test Cases/sub/subsub/TC1.

v10.3.2 still has a bug around moving/renaming a test case. See [http://forum.katalon.com/t/test-case-loses-its-code-when-moved-over-another-test-case-with-the-same-name/183734](http://forum.katalon.com/t/test-case-loses-its-code-when-moved-over-another-test-case-with-the-same-name/183734) ---
