What is the current behavior?

I am getting the following when calling Get-CoverTSql. Where is the debug output?

Exception calling "Cover" with "1" argument(s): "Unable to start the trace - errors are recorded in the debug output"
At C:\Users\hoffman\Documents\Apps\SQLCOver.0.4.1\SQLCover.ps1:19 char:2

+     ~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : SqlCoverException

Also tried using Get-CoverExe and is got an error message from OSQL.EXE indicating that I didn't set up the arg list correctly. The relevant line is commented out below.

Error: No user selected. Try with -U or -E switches

What is the expected behavior?
Not receiving an error message

Which versions of SQL Server and which OS are affected by this issue? Did this work in previous versions of our procedures?

Hi,

For the debug output run this:

$coverage = new-object SQLCover.CodeCoverage ($connectionString, $databaseName, $null, $true)
$coverage.Cover($query)

so for your script run:

# file: test.ps1 
$ErrorActionPreference = "Stop"  

cd c:\Users\hoffman\Documents\Apps\SQLcover

# https://the.agilesql.club/2016/04/sqlcover-code-coverage-for-sql-server-t-sql/
$coverPath='C:\Users\hoffman\Documents\Apps\SQLCOver.0.4.1'
$coverDLL="$coverPath\SQLCover.dll"
$coverPS1="$coverPath\SQLCover.ps1"
# osql and osqlArgs used for Get-CoverExe
$osql='C:\Program Files (x86)\Microsoft SQL Server\140\Tools\Binn\OSQL.EXE'
$server='GTR_DEV16'
$database='GTR'
$SQLuser='gtr_write'
$SQLpass='removed'  # 
$query="EXEC tSQLt.Run 'zut_clinvar_sub_curation.Test_update_sub_date'"
$connectionString = "Persist Security Info=False;User ID=$SQLuser;Password=$SQLpass;Initial Catalog=$database;Server=$server"
$osqlArgs="-S $server -d $database -U $SQLuser -P $SQLpass -i test.sql"
. $coverPS1
#$result = Get-CoverTSql "${coverDLL}" "${connectionString}" "${database}" "${query}"
#$result = Get-CoverExe "${coverDLL}"
$coverage = new-object SQLCover.CodeCoverage ($connectionString, $database, $null, $true)
$result = $coverage.Cover($query)

Can you tell me the error?

Thank you for your response. I had another error which I reported and have since deleted because it was an unrelated internal problem. Disregard whatever email was generated as a result. I apologize for the inconvenience.

Hi,

no problem - can you clarify what error you get now?

There is also a newer release 0.5.0 which has a number of big fixes, probably worth testing with:

https://github.com/GoEddie/SQLCover/releases/tag/0.5.0

[ncbidoug]

I am having permission issues and working with our DBA. Thanks for letting me know about the new version.

[ncbidoug]

I got the original error again with 0.4.1 and 0.5.0

$coverage = new-object SQLCover.CodeCoverage ($connectionString, $database, $null, $true)
$result = $coverage.Cover($query)
Export-OpenXml $result "testout.xml"

Adding a second argument, 0, didn't help.

@ncbidoug I would try the SQLCoverCore project using dotnet core 3.1. You can also use the debugger in visual studio code to track down your issue. I think correcting your powershell script would take more time than using the easier dll.

Example using dotnet core:

cd src/SQLCover/SqlCoverCore
mkdir -p TestCoverageOpenXml
dotnet run -- -c Get-CoverTSql -e Export-OpenXml -k "Server=localhost;Database=master;User ID=sa;Password=JdMsKZPBBA8kVFXVrj8d" -d DatabaseWithTests -q "tSQLt.runAll" -o TestCoverageOpenXml

you can also call the new dll directly, (not to be confused w/ the one targeting .net461

cd src/SQLCover/SqlCoverCore
dotnet build
.\bin\Debug\netcoreapp3.1\SQLCoverCore.exe -c Get-CoverTSql -e Export-OpenXml -k "Server=localhost;Database=master;User ID=sa;Password=JdMsKZPBBA8kVFXVrj8d" -d DatabaseWithTests -q "tSQLt.runAll" -o TestCoverageOpenXml
# or 
dotnet run .\bin\Debug\netcoreapp3.1\SQLCoverCore.dll -- -c Get-CoverTSql -e Export-OpenXml -k "Server=localhost;Database=master;User ID=sa;Password=JdMsKZPBBA8kVFXVrj8d" -d DatabaseWithTests -q "tSQLt.runAll" -o TestCoverageOpenXml
