nyc-config-typescript

Handy default configuration for instrumenting your TypeScript-backed
project with test coverage using nyc.

First install the dependencies:

``
npm i -D nyc source-map-support ts-node @istanbuljs/nyc-config-typescript
`

Your tsconfig.json must be configured to produce source maps, either inline or as sibling files.

.nycrc

And write a .nycrc that looks like this:

`js
{
"extends": "@istanbuljs/nyc-config-typescript",
// OPTIONAL if you want coverage reported on every file, including those that aren't tested:
"all": true
}
`

This package specifies the cache, exclude, and extension options for you - only override those if you absolutely must.
If you are going to modify include or exclude and you have specified a separate outDir in tsconfig.json, make sure that it remains included so that source mapping is possible.

Running Tests

$3

In test/mocha.opts:

`
--require ts-node/register #replace with ts-node/register/transpile-only if you have custom types
--require source-map-support/register
--recursive

`

Now setup the test scripts in your package.json like so (with the equivalent for your test runner):

`json
{
"test": "tsc && nyc mocha"
}
`

$3


In package.json:

`json
{
"test": "tsc && nyc --require ts-node/register jasmine"
}
``
