# Lab + TypeScript = 😍

> Take the [`@hapi/lab`](https://github.com/hapijs/lab) you know and love and add a sprinkling of built-in TypeScript support and out comes `ts-lab`, an opinionated spin on vanilla lab.

See [@hapi/lab](https://hapi.dev/family/lab/) on the official Hapi developer site for more information on Lab itself.

## Differences

`ts-lab` is not a fork of [`@hapi/lab`](https://github.com/hapijs/lab) but instead wraps it. At the time of writing, the justification for this decision isn't entirely clear but here we are. This repo exposes a binary `ts-lab` that forwards arguments to the `lab` binary exposed by [`@hapi/lab`](https://github.com/hapijs/lab) with the addition of arguments to add TypeScript support. The module also exposes an API that wraps [`@hapi/lab`'s API](https://hapi.dev/family/lab/?v=21.0.0#usage). The differences are outlined below:

1. Out-of-the-box support for tests authored in TypeScript.
2. Exposes an instance of [`@hapi/code`](https://github.com/hapijs/code)'s assertion library as the top-level `expect` export.
3. Changes the optional `flags` arguments passed into test functions such that:
   1. It no longer exports a mutable `.onCleanup` property.
   2. Exports a `.disposeOf(disposable: { dispose(): void }): void` function. This can be used to register multiple disposables for disposal during the test's clean-up phase.

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.
