This software release is used to run integration test of slapos softwares.
The approach is to use setuptools' integrated test runner, `python setup.py test`, to run tests.
The approach is to use python unittest runner to run tests.
The `python` used in this command will be a `zc.recipe.egg` interpreter with
all eggs pre-installed by this software release.

## Environment variables
The `environment-script` set all variabels except `SLAPOS_TEST_DEBUG` and `SLAPOS_TEST_VERBOSE` for you, but for reference, here is the list of variables which control the test runner:
The `environment-script` set all variables except `SLAPOS_TEST_DEBUG`, `SLAPOS_TEST_VERBOSE`, `SLAPOS_TEST_SKIP_SOFTWARE_CHECK` and `SLAPOS_TEST_SKIP_SOFTWARE_REBUILD` for you, but for reference, here is the list of variables which control the test runner:
| Variable | Description |
| --- | --- |
| `SLAPOS_TEST_VERBOSE` | If set to 1, debugging output will be printed on console. This also adjust the log level of python process running tests. When running on test nodes, this is not set, so keep this difference in mind if test rely on python logger |
| `SLAPOS_TEST_DEBUG` | If set to 1, `slapos node instance` and `slapos node software` will run with `--buildout-debug` flag, which will invoke python debugger on error. |
| `SLAPOS_TEST_SKIP_SOFTWARE_CHECK` | If set to 1, software checks will not be performed. This can be used to speed up running tests locally, as checking software is an expensive operation. |
| `SLAPOS_TEST_SKIP_SOFTWARE_REBUILD` | If set to 1, software will not be rebuilt before running the test. The default is to use `slapos node software --all`, which unconditionally rebuild all softwares and to use `slapos node software`, which installs the software only if it's not yet available when the environment variable is set to 1. |
| `SLAPOS_TEST_IPV6` | ipv6 used by this instance. Usually you want to use a global address here to be able to connect to this instance. |
| `SLAPOS_TEST_IPV4` | ipv4 used by this instance. |
| `SLAPOS_TEST_WORKING_DIR` | Path to use as a working directory to hold the standalone SlapOS. |
| `SLAPOS_TEST_SHARED_PART_LIST` | A `:` separated of paths to look for already installed shared parts. The SlapOS used in the test will not write in these, but will use a dedicated directory in `$SLAPOS_TEST_WORKING_DIR` |
| `SLAPOS_TEST_VERBOSE` | If set to 1, debugging output will be printed on console. This also adjust the log level of python process running tests. When running on test nodes, this is not set, so keep this difference in mind if test rely on python logger |
| `SLAPOS_TEST_DEBUG` | If set to 1, `slapos node instance` and `slapos node software` will run with `--buildout-debug` flag, which will invoke python debugger on error. |
## Frequently Asked Questions
### Where to find docs about the testing framework ?
Please refere to the docstrings from `slapos.testing` module, from `slapos.core` package.

### Can I run slapos commands to debug ?
The standalone slapos is created in `$SLAPOS_TEST_WORKING_DIR`. In this directory you will have a `bin/slapos` that you can run to start or stop services.
It's fine to use this command during development, but to programatically interract with the environment within the test, the recommended approach is to use supervisor XML-RPC API.

### How to use a development version of `slapos.cookbook` ?
......@@ -83,3 +86,7 @@ At the end of the test, a snapshot of the slapos instances is created. Sometimes
Most of the time, problems are because on test nodes paths are very long. One advanced technique to reproduce the problem in your development environment is to set `SLAPOS_TEST_WORKING_DIR` environment variable to a path with the same length as the ones on test nodes.
One way to make instances uses a slightly shorter path is to define `__partition_reference__` class attribute, so that the instances uses this as prefix instead of the class name.
### Can I run only specific test ?
Yes, please refer to python unittest documentation. For example, you can use `python_for_test -m unittest -v test_module.TestClass.test_function` to run only test function.
