# Building and Testing serverless-s3-cleaner

## Prerequisite Software

To build and test serverless-s3-cleaner, you need to download and install the following applications:

* [Node.js](https://nodejs.org), a javascript runtime environment.
* [Visual Studio Code](https://code.visualstudio.com) for editing and debugging code. Any other editor would work too.

## Building

To compile the code, do the following:

1. Run `npm install` in the repo root
2. Run `npm run build`. This runs a linter on the source code (via ESLint), then builds the plugin.

## Running and debugging unit tests

For unit testing, [Jasmine](https://jasmine.github.io) is used; tests are written in TypeScript.

To run tests once, use `npm test`.

To generate a coverage report, use `npm run test:ci`. When done, open `./coverage/index.html` with a browser to view the report.

To debug tests:

1. Open _serverless-s3-cleaner.code-workspace_ with Visual Studio Code
2. Focus the test you're debugging, as described in [Jasmine documentation](https://jasmine.github.io/2.1/focused_specs.html) and set breakpoints where necessary.
3. Switch to VSCode's Debug tab and select the _Debug Tests (workspace)_ configuration and run it.
