I have installed latest Visual studio 2022 and added CodedUI component while installing and then I tried to run my codedUI tests from command line with MStest.exe but I was facing the error 'File extension specified '.dll' is not a valid test extension. I was able to run the same tests using Visual studio 2017 command line .Can some one let me know why VS 2022 is not able to identify the extension. PFA for additional reference.

The warning that is printing is trying to lead you down the right path. mstest is obsolete. You need to switch to the vstest runner instead. Adjust your command line to use the newer tool. I suspect your problem will go away.
As for mstest it can generate this error in a variety of cases so there is potentially a pathing problem. If it doesn't find all the binaries it expects it can generate the error. This includes the test adapter and test framework assemblies. Given that you're running Jenkins I'd probably start by verifying the test path it is trying to run against. Another cause is misconfigured or missing toolset so I'd make sure you installed CodedUI as well. CodedUI is deprecated so it is possible that something is missing from the VS2022 release that Jenkins needs.
Hi ,
Currently that path might be pointing to jenkins folder which was created manually but we are not running from jenkins either in this case, and as per the document we have installed the CodedUI component from the visual studio installer and I hope that will be adding all the references of test framework libraries as vs 2017 will do. Even we tried switching to vstest runner but that shows a different error message
Error:
MSTestAdapter failed to discover tests in class 'IMAGINE.TestFramework.TestLibrary.Classification.clsClassification' of assembly 'C:\work\Jenkins\workspace\RL_NITFUnchipExtractshpMetadata_x64\TestDesign\TestSuite\NITFUnchipExtractshpMetadataTest.dll'. Reason Could not load file or assembly 'Microsoft.VisualStudio.QualityTools.CodedUITestFramework, Version=15.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified..
No test is available in C:\work\Jenkins\workspace\RL_NITFUnchipExtractshpMetadata_x64\TestDesign\TestSuite\NITFUnchipExtractshpMetadataTest.dll. Make sure that installed test discoverers & executors, platform & framework version settings are appropriate and try again. Additionally, path to test adapters can be specified using /TestAdapterPath command. Example /TestAdapterPath:<pathToCustomAdapters>.
A while back MSTest switched to requiring that you explicitly reference the Test Framework and Test Adapter packages. If you don't then it cannot find the tests. Make sure you've done that.
The version of the CodedUITest assembly is v15. That would be incorrect for VS 2022. The version for VS 2022 is v17.0.0.0 so it appears you have an outdated dependency that is targeting the older test assemblies. Alternatively you should be able to configure the test project to generate binding redirects automatically by adding the following to the test project.
<AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
<GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
