#### Running Tests Locally
|
||||
|
||||
To run tests, you'll need to install [bats 0.4.0](https://github.com/sstephenson/bats).
|
||||
To run tests, you need to prepare the docker image to test which must be tagged `jwilder/nginx-proxy:test`:
|
||||
|
||||
docker build -t jwilder/nginx-proxy:test . # build the Debian variant image
|
||||
|
||||
and call the [test/pytest.sh](test/pytest.sh) script.
|
||||
|
||||
Then build the Alpine variant of the image:
|
||||
|
||||
docker build -f Dockerfile.alpine -t jwilder/nginx-proxy:test . # build the Alpline variant image
|
||||
|
||||
and call the [test/pytest.sh](test/pytest.sh) script again.
|
||||
|
||||
|
||||
If your system has the `make` command, you can automate those tasks by calling:
|
||||
|
||||
make test
|
||||
|
||||
|
||||
You can learn more about how the test suite works and how to write new tests in the [test/README.md](test/README.md) file.

Test suite
|
||||
==========
|
||||
|
||||
This test suite is implemented on top of the [Bats](https://github.com/sstephenson/bats/blob/master/README.md) test framework.
|
||||
|
||||
It is intended to verify the correct behavior of the Docker image `jwilder/nginx-proxy:bats`.
|
||||
|
||||
Running the test suite
|
||||
----------------------
|
||||
|
||||
Make sure you have Bats installed, then run:
|
||||
|
||||
docker build -t jwilder/nginx-proxy:bats .
|
||||
bats test/
|
||||
Nginx proxy test suite
|
||||
======================
|
||||
|
||||
Install requirements
|
||||
--------------------
|
||||
|
||||
You need [python 2.7](https://www.python.org/) and [pip](https://pip.pypa.io/en/stable/installing/) installed. Then run the commands:
|
||||
|
||||
requirements/build.sh
|
||||
pip install -r requirements/python-requirements.txt
|
||||
|
||||
If you can't install those requirements on your computer, you can alternatively use the _pytest.sh_ script which will run the tests from a Docker container which has those requirements.
|
||||
|
||||
|
||||
Prepare the nginx-proxy test image
|
||||
----------------------------------
|
||||
|
||||
docker build -t jwilder/nginx-proxy:test ..
|
||||
|
||||
or if you want to test the alpine flavor:
|
||||
|
||||
docker build -t jwilder/nginx-proxy:test -f Dockerfile.alpine ..
|
||||
|
||||
make sure to tag that test image exactly `jwilder/nginx-proxy:test` or the test suite won't work.
|
||||
|
||||
|
||||
Run the test suite
|
||||
------------------
|
||||
|
||||
pytest
|
||||
|
||||
need more verbosity ?
|
||||
|
||||
pytest -s
|
||||
|
||||
|
||||
Run one single test module
|
||||
--------------------------
|
||||
|
||||
pytest test_nominal.py
|
||||
|
||||
|
||||
Write a test module
|
||||
-------------------
|
||||
|
||||
This test suite uses [pytest](http://doc.pytest.org/en/latest/). The [conftest.py](conftest.py) file will be automatically loaded by pytest and will provide you with two useful pytest [fixtures](http://doc.pytest.org/en/latest/fixture.html#fixture):
|
||||
|
||||
- docker_compose
|
||||
- nginxproxy
|
||||
|
||||
|
||||
### docker_compose fixture
|
||||
|
||||
When using the `docker_compose` fixture in a test, pytest will try to find a yml file named after your test module filename. For instance, if your test module is `test_example.py`, then the `docker_compose` fixture will try to load a `test_example.yml` [docker compose file](https://docs.docker.com/compose/compose-file/).
|
||||
|
||||
Once the docker compose file found, the fixture will remove all containers, run `docker-compose up`, and finally your test will be executed.
|
||||
|
||||
The fixture will run the _docker-compose_ command with the `-f` option to load the given compose file. So you can test your docker compose file syntax by running it yourself with:
|
||||
|
||||
docker-compose -f test_example.yml up -d
|
||||
|
||||
In the case you are running pytest from within a docker container, the `docker_compose` fixture will make sure the container running pytest is attached to all docker networks. That way, your test will be able to reach any of them.
|
||||
|
||||
In your tests, you can use the `docker_compose` variable to query and command the docker daemon as it provides you with a [client from the docker python module](https://docker-py.readthedocs.io/en/2.0.2/client.html#client-reference).
|
||||
|
||||
Also this fixture alters the way the python interpreter resolves domain names to IP addresses in the following ways:
|
||||
|
||||
Any domain name containing the substring `nginx-proxy` will resolve to the IP address of the container that was created from the `jwilder/nginx-proxy:test` image. So all the following domain names will resolve to the nginx-proxy container in tests:
|
||||
- `nginx-proxy`
|
||||
- `nginx-proxy.com`
|
||||
- `www.nginx-proxy.com`
|
||||
- `www.nginx-proxy.test`
|
||||
- `www.nginx-proxy`
|
||||
- `whatever.nginx-proxyooooooo`
|
||||
- ...
|
||||
|
||||
Any domain name ending with `XXX.container.docker` will resolve to the IP address of the XXX container.
|
||||
- `web1.container.docker` will resolve to the IP address of the `web1` container
|
||||
- `f00.web1.container.docker` will resolve to the IP address of the `web1` container
|
||||
- `anything.whatever.web2.container.docker` will resolve to the IP address of the `web2` container
|
||||
|
||||
Otherwise, domain names are resoved as usual using your system DNS resolver.
|
||||
|
||||
|
||||
### nginxproxy fixture
|
||||
|
||||
The `nginxproxy` fixture will provide you with a replacement for the python [requests](https://pypi.python.org/pypi/requests/) module. This replacement will just repeat up to 30 times a requests if it receives the HTTP error 404 or 502. This error occurs when you try to send queries to nginx-proxy too early after the container creation.
|
||||
|
||||
Also this requests replacement is preconfigured to use the Certificate Authority root certificate [certs/ca-root.crt](certs/) to validate https connections.
|
||||
|
||||
Furthermore, the nginxproxy methods accept an additional keyword parameter: `ipv6` which forces requests made against containers to use the containers IPv6 address when set to `True`. If IPv6 is not supported by the system or docker, that particular test will be skipped.
|
||||
|
||||
def test_forwards_to_web1_ipv6(docker_compose, nginxproxy):
|
||||
r = nginxproxy.get("http://web1.nginx-proxy.tld/port", ipv6=True)
|
||||
assert r.status_code == 200
|
||||
assert r.text == "answer from port 81\n"
|
||||
|
||||
|
||||
|
||||
### The web docker image
|
||||
|
||||
When you ran the `requirements/build.sh` script earlier, you built a [`web`](requirements/README.md) docker image which is convenient for running a small web server in a container. This image can produce containers that listens on multiple ports at the same time.
|
||||
|
||||
|
||||
### Testing TLS
|
||||
|
||||
If you need to create server certificates, use the [`certs/create_server_certificate.sh`](certs/) script. Pytest will be able to validate any certificate issued from this script.

# information on failure to help debugging. They return 1 on failure

This is an optional requirement which is usefull if you cannot (or don't want to) install pytest and its requirements on your computer. In this case, you can use the `nginx-proxy-tester` docker image to run the test suite from a Docker container.

To use this image, it is mandatory to run the container using the `test.sh` shell script. The script will build the image and run a container from it with the appropriate volumes and settings.

Nginx proxy test suite
|
||||
======================
|
||||
|
||||
Install requirements
|
||||
--------------------
|
||||
|
||||
You need [python 2.7](https://www.python.org/) and [pip](https://pip.pypa.io/en/stable/installing/) installed. Then run the commands:
|
||||
|
||||
requirements/build.sh
|
||||
pip install -r requirements/python-requirements.txt
|
||||
|
||||
If you can't install those requirements on your computer, you can alternatively use the _test.sh_ script which will run the tests from a Docker container which has those requirements.
|
||||
|
||||
|
||||
Prepare the nginx-proxy test image
|
||||
----------------------------------
|
||||
|
||||
docker build -t jwilder/nginx-proxy:test ..
|
||||
|
||||
or if you want to test the alpine flavor:
|
||||
|
||||
docker build -t jwilder/nginx-proxy:test -f Dockerfile.alpine ..
|
||||
|
||||
make sure to tag that test image exactly `jwilder/nginx-proxy:test` or the test suite won't work.
|
||||
|
||||
|
||||
Run the test suite
|
||||
------------------
|
||||
|
||||
pytest
|
||||
|
||||
need more verbosity ?
|
||||
|
||||
pytest -s
|
||||
|
||||
|
||||
Run one single test module
|
||||
--------------------------
|
||||
|
||||
pytest test_nominal.py
|
||||
|
||||
|
||||
Write a test module
|
||||
-------------------
|
||||
|
||||
This test suite uses [pytest](http://doc.pytest.org/en/latest/). The [conftest.py](conftest.py) file will be automatically loaded by pytest and will provide you with two useful pytest [fixtures](http://doc.pytest.org/en/latest/fixture.html#fixture):
|
||||
|
||||
- docker_compose
|
||||
- nginxproxy
|
||||
|
||||
|
||||
### docker_compose fixture
|
||||
|
||||
When using the `docker_compose` fixture in a test, pytest will try to find a yml file named after your test module filename. For instance, if your test module is `test_example.py`, then the `docker_compose` fixture will try to load a `test_example.yml` [docker compose file](https://docs.docker.com/compose/compose-file/).
|
||||
|
||||
Once the docker compose file found, the fixture will remove all containers, run `docker-compose up`, and finally your test will be executed.
|
||||
|
||||
The fixture will run the _docker-compose_ command with the `-f` option to load the given compose file. So you can test your docker compose file syntax by running it yourself with:
|
||||
|
||||
docker-compose -f test_example.yml up -d
|
||||
|
||||
In the case you are running pytest from within a docker container, the `docker_compose` fixture will make sure the container running pytest is attached to all docker networks. That way, your test will be able to reach any of them.
|
||||
|
||||
In your tests, you can use the `docker_compose` variable to query and command the docker daemon as it provides you with a [client from the docker python module](https://docker-py.readthedocs.io/en/2.0.2/client.html#client-reference).
|
||||
|
||||
Also this fixture alters the way the python interpreter resolves domain names to IP addresses in the following ways:
|
||||
|
||||
Any domain name containing the substring `nginx-proxy` will resolve to the IP address of the container that was created from the `jwilder/nginx-proxy:test` image. So all the following domain names will resolve to the nginx-proxy container in tests:
|
||||
- `nginx-proxy`
|
||||
- `nginx-proxy.com`
|
||||
- `www.nginx-proxy.com`
|
||||
- `www.nginx-proxy.test`
|
||||
- `www.nginx-proxy`
|
||||
- `whatever.nginx-proxyooooooo`
|
||||
- ...
|
||||
|
||||
Any domain name ending with `XXX.container.docker` will resolve to the IP address of the XXX container.
|
||||
- `web1.container.docker` will resolve to the IP address of the `web1` container
|
||||
- `f00.web1.container.docker` will resolve to the IP address of the `web1` container
|
||||
- `anything.whatever.web2.container.docker` will resolve to the IP address of the `web2` container
|
||||
|
||||
Otherwise, domain names are resoved as usual using your system DNS resolver.
|
||||
|
||||
|
||||
### nginxproxy fixture
|
||||
|
||||
The `nginxproxy` fixture will provide you with a replacement for the python [requests](https://pypi.python.org/pypi/requests/) module. This replacement will just repeat up to 30 times a requests if it receives the HTTP error 404 or 502. This error occurs when you try to send queries to nginx-proxy too early after the container creation.
|
||||
|
||||
Also this requests replacement is preconfigured to use the Certificate Authority root certificate [certs/ca-root.crt](certs/) to validate https connections.
|
||||
|
||||
Furthermore, the nginxproxy methods accept an additional keyword parameter: `ipv6` which forces requests made against containers to use the containers IPv6 address when set to `True`. If IPv6 is not supported by the system or docker, that particular test will be skipped.
|
||||
|
||||
def test_forwards_to_web1_ipv6(docker_compose, nginxproxy):
|
||||
r = nginxproxy.get("http://web1.nginx-proxy.tld/port", ipv6=True)
|
||||
assert r.status_code == 200
|
||||
assert r.text == "answer from port 81\n"
|
||||
|
||||
|
||||
|
||||
### The web docker image
|
||||
|
||||
When you ran the `requirements/build.sh` script earlier, you built a [`web`](requirements/README.md) docker image which is convenient for running a small web server in a container. This image can produce containers that listens on multiple ports at the same time.
|
||||
|
||||
|
||||
### Testing TLS
|
||||
|
||||
If you need to create server certificates, use the [`certs/create_server_certificate.sh`](certs/) script. Pytest will be able to validate any certificate issued from this script.
