This patch makes the tests (including the test driver) run entirely inside Vagrant, which avoids calling the very slow `vagrant` driver many times for running the tests. On my machine, `./test` runs in 22 seconds, down from hundreds of seconds prior to this patch. This also has the nice side effect of matching how the Travis CI tests were run, so there's no need for a separate `test_travis` anymore.

Testing
|
|
=======
|
|
|
|
Dotbot testing code uses [Vagrant] to run all tests inside a virtual machine to
|
|
have tests be completely isolated from the host machine.
|
|
|
|
Installing the Test environnement
|
|
---------------------------------
|
|
|
|
### Debian-based distributions
|
|
|
|
- Install the test requirements
|
|
|
|
```bash
|
|
sudo apt install vagrant virtualbox
|
|
```
|
|
|
|
- Install Dotbot dependencies
|
|
|
|
```bash
|
|
git submodule update --init --recursive
|
|
```
|
|
|
|
### macOS
|
|
|
|
- Install the test requirements
|
|
- [VirtualBox]
|
|
- [Vagrant]
|
|
|
|
- Install Dotbot dependencies
|
|
|
|
```bash
|
|
git submodule update --init --recursive
|
|
```
|
|
|
|
Running the Tests
|
|
-----------------
|
|
|
|
Before running the tests, you must SSH into the VM. Start it with `vagrant up`
|
|
and SSH in with `vagrant ssh`. All following commands must be run inside the
|
|
VM.
|
|
|
|
First, you must install a version of Python to test against, using `pyenv
|
|
install -s {version}`. You can choose any version you like, e.g. `3.8.1`. It
|
|
isn't particularly important to test against all supported versions of Python
|
|
in the VM, because they will be tested by CI. Once you've installed a specific
|
|
version of Python, activate it with `pyenv global {version}`.
|
|
|
|
The VM mounts the Dotbot directory in `/dotbot` as read-only (you can make
|
|
edits on your host machine). You can run the test suite by `cd /dotbot/test`
|
|
and then running `./test`. Selected tests can be run by passing paths to the
|
|
tests as arguments, e.g. `./test tests/create.bash tests/defaults.bash`.
|
|
|
|
To debug tests, you can prepend the line `DEBUG=true` as the first line to any
|
|
individual test (a `.bash` file inside `test/tests`). This will enable printing
|
|
stdout/stderr.
|
|
|
|
When finished with testing, it is good to shut down the virtual machine by
|
|
running `vagrant halt`.
