Code Coverage Generator

How is this not a part of the CLI? Maybe it is, but I sure couldn’t find it…

Description

Deno is really nice in that it allows for users to generate code coverage data directly from tests. However, this data is not very human readable. But wait! they have a built-in tool (deno coverage) that will generate a report. Unfortunately, I find this report hard to read, so we’ve made a new one.

Usage

First, you will need to install the script with

deno install -A --no-check -n code-coverage https://deno.land/x/code_coverage/cli.ts

From there in any project you should be able to run

code-coverage

This looks for an lcov.info file in the directory the command is being run in. You can change the file name with

code-coverage --file coverage.lcov
