VSTS Build - Coded UI Tests Could not be found during Build's Test Execution

Question

I have a Coded UI test program that runs without any error on local Visual Studio (2017). Only one test method is in the program. One feature it has is saving file in Azure Storage container. During build's Test Runs process, Build message says it cannot find any tests. Hoping for any feedback to see if I am making any error in build definition.

The build message says:

No test is available in D:\a\3\s\FullSite1\bin\Debug\FullSite1.dll D:\a\3\s\FullSite1\bin\Debug\Microsoft.Azure.KeyVault.Core.dll D:\a\3\s\FullSite1\bin\Debug\Microsoft.Data.Edm.dll D:\a\3\s\FullSite1\bin\Debug\Microsoft.Data.OData.dll D:\a\3\s\FullSite1\bin\Debug\Microsoft.Data.Services.Client.dll D:\a\3\s\FullSite1\bin\Debug\Microsoft.WindowsAzure.Storage.dll D:\a\3\s\FullSite1\bin\Debug\Newtonsoft.Json.dll D:\a\3\s\packages\Microsoft.Azure.KeyVault.Core.1.0.0\lib\net40\Microsoft.Azure.KeyVault.Core.dll D:\a\3\s\packages\Microsoft.Azure.KeyVault.Core.1.0.0\lib\portable-net45+wp8+wpa81+win\Microsoft.Azure.KeyVault.Core.dll D:\a\3\s\packages\Newtonsoft.Json.10.0.2\lib\net20\Newtonsoft.Json.dll D:\a\3\s\packages\Newtonsoft.Json.10.0.2\lib\net35\Newtonsoft.Json.dll D:\a\3\s\packages\Newtonsoft.Json.10.0.2\lib\net40\Newtonsoft.Json.dll D:\a\3\s\packages\Newtonsoft.Json.10.0.2\lib\net45\Newtonsoft.Json.dll D:\a\3\s\packages\Newtonsoft.Json.10.0.2\lib\netstandard1.0\Newtonsoft.Json.dll D:\a\3\s\packages\Newtonsoft.Json.10.0.2\lib\netstandard1.3\Newtonsoft.Json.dll D:\a\3\s\packages\Newtonsoft.Json.10.0.2\lib\portable-net40+sl5+win8+wpa81+wp8\Newtonsoft.Json.dll D:\a\3\s\packages\Newtonsoft.Json.10.0.2\lib\portable-net45+win8+wpa81+wp8\Newtonsoft.Json.dll D:\a\3\s\packages\WindowsAzure.Storage.9.1.1\lib\net45\Microsoft.WindowsAzure.Storage.dll D:\a\3\s\packages\WindowsAzure.Storage.9.1.1\lib\netstandard1.0\Microsoft.WindowsAzure.Storage.dll D:\a\3\s\packages\WindowsAzure.Storage.9.1.1\lib\netstandard1.3\Microsoft.WindowsAzure.Storage.dll D:\a\3\s\packages\WindowsAzure.Storage.9.1.1\lib\win8\Microsoft.WindowsAzure.Storage.dll D:\a\3\s\packages\WindowsAzure.Storage.9.1.1\lib\wp8\Microsoft.WindowsAzure.Storage.dll D:\a\3\s\packages\WindowsAzure.Storage.9.1.1\lib\wpa\Microsoft.WindowsAzure.Storage.dll. Make sure that test discoverer & executors are registered and platform & framework version settings are appropriate and try again.

I am using the following in the build definition:

What's the name of your test project? Is it a general Coded UI test project? — starian chen-MSFT
Can you provide the screenshot of Build pipeline & Coded UI task to check the pipeline & configuration — Shalem
Thanks for the feedback. I have found the issue. It was a second CodedUITest.cs file and was missing [CodedUITest] - that was the reason VSTS couldn't find any test method. — Sohel

After comparing the code with another test I found the reason was because CodedUITest.cs file was missing [CodedUITest] after the namespace. I have added it and VSTS now can find the test method.
