I am running an Xcode test command in the terminal. Here is the command

xcodebuild test -project $project_dir/Application.xcodeproj -scheme Application -sdk iphoneos -destination id=$UDID >> $LOGFILE_PATH

But my test case has failed with the error "Failed to install or launch the test runner. (Underlying error: Xcode encountered an error. Could not connect to the device)"

Attached is the screenshot for error log.Screenshot for error log

Also, please let us know if you tried detaching and reattaching the device, etc. – auspicious99 Apr 24 '20 at 07:04
@auspicious99 I have tested the device connectivity after the xcodebuild test command using "instruments -s devices" command , the device is shown as connected – Yogesh Solanki Apr 24 '20 at 07:13
