Display test coverage generated by lcov or xml in Visual Studio Code

[josecelano]

Hi @WarmBeer @da2ce7, There is a Visual Studio Code extension to show the line coverage.

Extension: https://marketplace.visualstudio.com/items?itemName=ryanluker.vscode-coverage-gutters

Install

1. Install llvm-cov: https://github.com/taiki-e/cargo-llvm-cov
2. Install the VSCode extension: https://marketplace.visualstudio.com/items?itemName=ryanluker.vscode-coverage-gutters

Run

cargo llvm-cov --lcov --output-path=./coverage/lcov.info

That command will generate a lcov file. The extension automatically looks for files with that extension.

On the navigation bar, you will see a new option:

You can change the extension settings to show always the line coverage:

You can easily see what lines are not covered yet.
