brew install lcovDeno Subprocess
Deno is capable of spawning a subprocess and supports url imports. As a result,
a code coverage report can be generated via the command line. There is no need
to install any dependencies, just open a command line where you would normally
run deno test and use the following code.
deno run --allow-run --allow-read --allow-write https://deno.land/x/simple_coverage@v1.0.2/coverage.tsor
deno run --allow-all https://deno.land/x/simple_coverage@v1.0.2/coverage.tsAdditionally pass open as an argument to open the coverage report
deno run --allow-all https://deno.land/x/simple_coverage@v1.0.2/coverage.ts openBash
Alternativly you can acheive the same results by using the provided Bash script. First copy the contents of coverage.sh to a project or this script can also added to a project via a command line
curl -sL https://deno.land/x/simple_coverage@v1.0.2/coverage.sh -o coverage.shafter adding the script to a project a test coverage report can generated with
sh coverage.sh
