# Structure
# Tests

The Unit-Tests do not follow exactly the file structure of Powerlevel9k itself.
## Automated Tests

## Basic Tests
The Unit-Tests do not follow exactly the file structure of Powerlevel9k itself,
but we try to reflect the structure as much as possible. All tests are located
under `test/`. Segment specific tests under `test/segments/` (one file per

Basic Tests belong in `test/powerlevel9k.spec` if they test basic functionality of
Powerlevel9k itself. Basic functions from the `functions` directory have their
Tests in separate files under `test/functions`.
### Installation

## Segment Tests
In order to execute the tests you need to install `shunit2`, which is a
submodule. To install the submodule, you can execute
`git submodule init && git submodule update`.

These Tests tend to be more complex in setup than the basic tests. To avoid ending
up in a huge single file, there is one file per segment in `test/segments`.
### Executing tests

# Manual Testing
The tests are shell scripts on their own. So you can execute them right away.
To execute all tests you could just execute `./test/suite.spec`.

### General Test Structure

The tests usually have a `setUp()` function which is executed before every
test function. Speaking of, test functions must be prefixed with `test`. In
the tests, you can do [different Assertions](
It is always a good idea to mock the program you want to test (just have a
look at other tests), so that the testrunner does not have to have all
programs installed.

### Travis

We use [Travis]( for Continuous Integration. This
service executes our tests after every push. For now, we need to tell travis
where to find the tests, which is what happens in the `.travis.yml` file.

## Manual Testing

If unit tests are not sufficient (e.g. you have an issue with your prompt that
occurs only in a specific ZSH framework) then you can use either Docker or
or our Vagrant.

## Docker
### Docker

This is the easiest to use _if_ you have Docker already installed and running.

**Note:** Not all frameworks work with all versions of ZSH (or the underlying OS).

## Vagrant
### Vagrant

Currently there are two test VMs. `test-vm` is an Ubuntu machine with several
pre-installed ZSH frameworks. And there is `test-bsd-vm` which is a FreeBSD!
