ltdps/e2e repository overview

⁠edx-e2e-tests

End-to-end tests for edX applications.

⁠Overview

UI-level tests for edX applications:

• pages: PageObjects for interacting with pages under test.
• e2e_test: Bokchoy tests for the Learning Management System (LMS) and Studio.

⁠Installation

You will also need a deployed installation of edX lms and studio to run the tests against. See edx/configuration <http://github.com/edx/configuration>_ for instructions on provisioning an edX instance. For additional information on how to setup your development environment, see Developer Onboarding <https://openedx.atlassian.net/wiki/pages/viewpage.action?spaceKey=ENG&title=Developer+Onboarding#DeveloperOnboarding-Step4:Getreadytodevelop>_

⁠Devstack

If you are running against devstack you are in luck! E2E test functionality is built-in and you can run it using the make e2e-tests make command from the devstack directory.

⁠Using Docker

1. Clone the repo:

.. code:: bash

git clone https://github.com/edx/edx-e2e-tests

2. Share your directory:

Make sure your edx-e2e-tests directory is shared in Docker settings or the next step will fail

1. Build up:

.. code:: bash

docker-compose up --build

4. Open a new terminal window and work inside the container:

.. code:: bash

docker exec -it edxe2etests /bin/bash

5. Set the environment variables:

You will need to configure the target environment that you want to run tests against. There is an example file that has all of the environment variables that need to be exported. Copy local_env.sh.sample to a new file and update the variables as necessary. Once done, source the file to get all of the variables into your environment.

1. Run lms and studio tests, as given below in 'How to run LMS and Studio tests' section

2. In OSX at least (not sure about other host systems) you can VNC in with the following (the password is 'secret'):

.. code:: bash

open vnc://localhost:35900

⁠Creating a test course on stage

By default, the tests in this repo run against our staging server. If you plan to keep this as the target environment, you must create your own course on stage (this requires an account with staff access). Using your own course will prevent collisions with other developers and ensure that your test results are accurate.

To create the course:

1. Log into studio.edx.org with staff credentials

2. Create a new course. To ensure that your course is unique, use your github username as the Course Number. Make sure you select Organization and Course Run as well. The Course Name won't matter here, as it will be overwritten to "E2E Test Course" by the next step. These values will be set as environment variables when actually running the tests. For more on this, see How to run LMS and Studio tests

3. Go to the course import page and upload the course.tar.gz file found in the upload_files directory of this repo. This tarball will generate a fairly simple test course that includes all of the advanced modules necessary for the e2e tests.

⁠Configuration

1. Before running the commands change your working directory to edx-e2e-tests. Note that the 'e2e' python virtual environment will automatically be activated.

.. code:: bash

cd edx-e2e-tests/

2. Update the base python requirements in case they have changed since you created the environment:

.. code:: bash

pip install -r requirements/base.txt

3. OPTIONAL: Cloning the edx-platform repo into a mounted directory in a docker environment can take a long time (several minutes). An alternative is to navigate to the lib directory back on your host system and clone the edx-platform repo there before proceeding.

1. Install the page objects for the application from the edx platform repo. This will clone the entire repo into lib/edx-platform so that it can use the page objects and helper methods from common/test/acceptance. We also install capa and xmodule into the virtual environment from common/lib.

.. code:: bash

paver install_pages

⁠How to run LMS and Studio tests

Before running tests, please ensure that following environment variables are set.

.. code:: bash

==> BASIC_AUTH_USER
==> BASIC_AUTH_PASSWORD
==> USER_LOGIN_EMAIL
==> USER_LOGIN_PASSWORD
==> COURSE_RUN
==> COURSE_DISPLAY_NAME
==> COURSE_NUMBER
==> COURSE_ORG

To run all the tests:

.. code:: bash

paver e2e_test --exclude=whitelabel

The commands also accept nose-style specifiers for test case or module:

To run all the tests in the file:

.. code:: bash

paver e2e_test lms/test_dashboard.py

To run all the tests in a particular class:

.. code:: bash

paver e2e_test lms/test_dashboard.py:DashboardTest

To run a single test:

.. code:: bash

paver e2e_test lms/test_dashboard.py:DashboardTest.test_resume_course

To update page objects installed from external repos:

.. code:: bash

paver install_pages

⁠How to run Whitelabel tests

1. Create a virtual environment for installation/executing tests.

2. Change your working directory to edx-e2e-tests.

.. code:: bash

cd edx-e2e-tests/

3. Install the requirements

.. code:: bash

pip install -r requirements/base.txt

4. Install the page objects for the application from the edx platform repo. This will clone the entire repo into lib/edx-platform so that it can use the page objects and helper methods from common/test/acceptance. We also install capa and xmodule into the virtual environment from common/lib.

.. code:: bash

paver install_pages

5. Set these Environment variables

.. code:: bash

==> TEST_ENV (Only required if tests are not running on stage, e.g. for sandbox just assign value `sandbox')
==> TARGET_DNS (Only required if tests are not running on stage, just provide DNS e.g. just provide "helio" for "https://mitxpro-helio.sandbox.edx.org")
==> ORG (Only valid values for now are "MITxPRO" and "HarvardMedGlobalAcademy", if not provided the tests wil run against MITxPRO by default)
==> BASIC_AUTH_USER
==> BASIC_AUTH_PASSWORD
==> GLOBAL_PASSWORD
==> OAUTH_CLIENT_ID (Only required for stage or sandbox is not using the default id)
==> OAUTH_CLIENT_SECRET (Only required for stage or sandbox is not using the default secret)
==> COURSE_RUN (Optional, use only if you are using a value other than default)
==> COURSE_DISPLAY_NAME (Optional, use only if you are using a value other than default)
==> COURSE_NUMBER (Optional, use only if you are using a value other than default)
==> COURSE_ORG (Optional, use only if you are using a value other than specified in ORG var)

To run all the tests in the file:

.. code:: bash

paver e2e_wl_test

To run all the tests in the file:

.. code:: bash

paver e2e_wl_test test_otto_enrollment.py

To run all the tests in a particular class:

.. code:: bash

paver e2e_wl_test test_misc.py:TestMisc

To run a single test:

.. code:: bash

paver e2e_wl_test test_misc.py:TestMisc.test_logos

⁠Where and How to add new tests

Change your working directory to regression/tests. Add your tests to the below mentioned directories based on the relevancy of the tests.

1. `lms`: tests for the LMS pages
2. `studio`: tests for the studio pages
3. `whitelabel`: tests for microsites
4. `helpers`: helper methods for the tests
5. `common`: tests required for common components of lms and studio

NOTE: Please make a pull request from the master branch before writing and adding new tests.

⁠How to change target environment?

Studio and LMS urls for stage are https://studio.stage.edx.org and https://courses.stage.edx.org respectively. We don't need to do anything extra to run tests on stage. By default, all tests run on stage.

If we want to change this behaviour then we would need to set environment variables to point to our desired environment. To be specific, we would need to set

1. For studio, STUDIO_BASE_URL which defaults to studio.stage.edx.org and

2. For LMS, LMS_BASE_URL which defaults to courses.stage.edx.org.

Lets say we want to run tests on a sandbox which has studio and LMS urls as https://studio.sandbox.edx.org and https://lms.sandbox.edx.org respectively. To let repo know, set environment variables as

.. code:: bash

export STUDIO_BASE_URL=studio.sandbox.edx.org
export LMS_BASE_URL=lms.sandbox.edx.org

Depending on the target environment you may also need to change LMS_PROTOCOL and STUDIO_PROTOCOL to http or https.

To run tests back on stage, unset the above set environment variables.

.. code:: bash

unset STUDIO_BASE_URL
unset LMS_BASE_URL
