Install ReportPortal.Extensions.SourceBack nuget package into tests project and see in report where exactly test was failed.

How it works

This package embedds your tests source code into pdb file. When test fails, SourceBack package tracks exceptions stacktrace and inserts corresponding piece of code. This works even if you build and execute tests on different machines.

Requirements

You should compile test project with portable or embedded debug type option. This is already set for the most of projects by default. To change it: right click on the project in Solution Explorer window and then Properties > Build > Advanced > Debugging Information.

Configuration

Configuration parameters are optional. Example for default ReportPortal.config.json file

{
  "Extensions": {
    "SourceBack": {
        "OffsetUp": 4,
        "OffsetDown": 2
      }
   }
}

And alternative is via environment variables like ReportPortal_Extensions_SourceBack_OffsetUp. Read more about it.

List of configuration parameters

Name	Description
ReportPortalExtensionsSourceBackOffsetUp	How many lines of code above to capture. Default: 4.
ReportPortalExtensionsSourceBackOffsetDown	How many lines of code below to capture. Default: 2.
ReportPortalExtensionsSourceBack_OpenWith	Program where to open highlighted line of code. Currently only Visual Studio Code is supported. Default: vscode.

Troubleshooting

Incorrect highlighed line in report

Sometimes this extension doesn't highlight the line of code properly if project is built with Code Optimization enabled. Usually this option is disabled in Debug configuration (Right click on the project Properties > Build > Disable Optimize code).

Internal Tracing

If something doesn't work as you expect, please set environment variable ReportPortal_TraceLevel=Verbose to turn on internal report portal tracing. See verbosed messages in ReportPortal.*.log files.
