.Synopsis
|
||
Format the coverage data for a file
|
||
.Description
|
||
Show the lines which were hit or not in a specific file. Line numbers are included in the output.
|
||
If a line was hit during a test run a '+' will follow the line number, if a line was missed, a '-'
|
||
will follow the line number. If a line is not hittable, it will not show '+' or '-'.
|
||
|
||
You can map file locations with the -oldBase and -newBase parameters (see example below), so you can
|
||
view coverage on a system with a different file layout. It is obvious to note that if files are different
|
||
between the systems, the results will be misleading
|
||
.EXAMPLE
|
||
PS> $coverage = Get-CodeCoverage -CoverageXmlFile .\opencover.xml
|
||
PS> Format-FileCoverage -FileCoverageData $coverage.FileCoverage -filter "CredSSP.cs"
