The Testcontainers module for K6.


### Using k6 extensions

This module takes advantage of [k6x](https://github.com/szkiba/k6x) to dynamically build a `k6` binary with all the [k6 extensions](https://k6.io/docs/extensions/get-started/explore/) required by the test script.

#### SetEnvVar

`SetEnvVar` sets an [environment variable](https://k6.io/docs/using-k6/environment-variables/) for the test script using the '--env' command-line flag in the k6 command in the container.
