# Code Coverage
Wasabi Wallet is built using dotnet core. Given there is no cross-platform Profiling API like the one available on Windows, we use AltCover package for instrumenting the assemblies and recording the execution coverage.
So, first of all we need to install the package in the WalletWasabi.Tests project as follow:
dotnet add WalletWasabi.Tests/WalletWasabi.Tests.csproj package AltCover
dotnet test /p:AltCover=true /p:AltCoverLcovReport=lcov.info
As a result we get a
lcov.info file containing the covered lines.
In order to be able to see what lines
are covered we need to install a
vscode extension called Coverage Gutters.
