# Test include > Source: [https://github.com/juju/juju/tree/main/tests/includes](https://github.com/juju/juju/tree/main/tests/includes) In Juju, test **includes** are special `bash` util functions designed to help in creating effective integration test suites for `juju`. This document gives the complete list (STILL UNDER CONSTRUCTION) along with quick descriptions. | | | | |---------------|-----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `check` | | Various check functions that help to analyse the output of cli commands and define if test passed or not. Most commonly used: `check_contains`, `check`, `check_gt`. | | `cleanup` | | Functions that clean up after test is complete. | | `colors` | | Colorize the output if the terminal supports doing this. | | `date` | | Add date to test output. | | `expect-that` | | The ability to work with interactive commands with expect tool. | | `juju` | | Functions that allow to operate with juju bootstrap, models, controllers. E.g., `ensure`, `bootstrap`, … | | | `destroy-model` | Takes a model name and destroys the model. | | | `ensure` | Ensures that there is a bootstrapped controller with model ``. | | `random` | | Generated random string. | | `run` | | Run a command and immediately terminate the script when any error occurs. | | `storage` | | Functions which help to test the storages. | | `verbose` | | Define the level of verbosity. There are three levels of verbosity. Both 1 and 2 will fail on any error – the difference is that 2 will also turn on `juju debug` statements, though not shell debug statements. |
