# Troubleshooting
|
|
|
|
## Msbuild Integration
|
|
|
|
1) Generate verbose log
|
|
```
|
|
dotnet test test\coverlet.core.tests\coverlet.core.tests.csproj -c debug /p:CollectCoverage=true /p:CoverletOutputFormat=opencover /p:Include=[coverlet.*]* -verbosity:diagnostic -bl:msbuild.binlog -noconsolelogger
|
|
```
|
|
|
|
2) Download http://msbuildlog.com/
|
|
3) Open `msbuild.binlog` generated and search for '[coverlet]' logs
|
|
|
|
|
|
|
|
## Coverlet Global Tool
|
|
|
|
```
|
|
coverlet "C:\git\coverlet\test\coverlet.core.tests\bin\Debug\netcoreapp2.0\coverlet.core.tests.dll" --target "dotnet" --targetargs "test C:\git\coverlet\test\coverlet.core.tests --no-build" --verbosity detailed
|
|
```
|
|

## Use local build
|
|
|
|
Sometimes is useful test local updated source to fix issue.
|
|
You can "load" your local build using simple switch:
|
|
|
|
* build repo
|
|
|
|
```
|
|
D:\git\coverlet (fixjsonserializerbug -> origin)
|
|
λ dotnet build

|

|
|
* Go to repro project and run
|
|
```
|
|
D:\git\Cake.Codecov\Source\Cake.Codecov.Tests (develop -> origin)
|
|
λ dotnet test /p:CollectCoverage=true /p:Exclude="[xunit.*]*" /p:CoverletToolsPath=D:\git\coverlet\src\coverlet.msbuild.tasks\bin\Debug\netstandard2.0\
|
|
Test run for D:\git\Cake.Codecov\Source\Cake.Codecov.Tests\bin\Debug\netcoreapp2.0\Cake.Codecov.Tests.dll(.NETCoreApp,Version=v2.0)
|
|
...
|
|
```
|
|
|
|
In this way you can add `Debug.Launch()` inside coverlet source and debug. |
