function Convert-DataToTeamcityTest {
    <#
    .SYNOPSIS
    Convert input dataset into TeamCity test service messages.
     
    .PARAMETER InputData
    Input data set.
 
    .PARAMETER ColumnTestName
    Column indicates the name of the test.
     
    .PARAMETER ColumnsToReportAsTests
    List of columns that will be reported as TeamCity tests (each column will be mapped to one category).
    For example, if $ColumnsToReportsAsTests = @('average','median') and you have tests 'x', 'y', there will be
    tests average.x, average.y, median.x, median.y
 
    .PARAMETER TestSuiteName
    Name of test suite that will be reported to TeamCity.
 
    .PARAMETER TestNames
    When parameter is specified, then only test names specified in this list are taken into consideration.
    Names contained in the ColumnTestName will be filtered into
    Otherwise (when parameter is not specified) there is no filter.
 
    .PARAMETER IgnoreTestNames
    List of test names to ignore in TeamCity. (Only used if $TestNames parameter is not specified.)
 
    .PARAMETER ColumnTestFailure
    Name of dataset column containing information about test errors (decimal number).
    If greater than FailureThreshold, the test will be marked as failed.
 
    .PARAMETER FailureThreshold
    Threshold for $ColumnTestFailure parameter, above which test will be marked as failed.
 
    .EXAMPLE
    Convert-DataToTeamcityTest -InputData $InputData -ColumnTestName 'Name' -ColumnsToReportAsTests 'Average'
