Thanks for the reply, I added Project \> Settings \> Library Management external jars. As soon as I add the external jar to Import, the testcase cannot be run at all. When I press the Run button, the testcase is saved, but it doesn’t run and it doesn’t give any errors. ---

Hello, I added the Library Management external jar, which I blurted out in the screenshot. In the testcase import I called the code inside the external jar. The test case does not run when I press the test case run button. The test case works when the same test case is in the test suite. ![librarymanagement](https://europe1.discourse-cdn.com/katalon/original/3X/9/6/965bad21d11b275d458cbeea9cffbdeffeb7b5dc.png) ---
