edx-proctoring 3.4.0

Proctoring subsystem for Open edX

This is the exam proctoring subsystem for the Open edX platform.

Overview

Proctored exams are exams with time limits that learners complete while online proctoring software monitors their computers and behavior for activity that might be evidence of cheating. This Python library provides the proctoring implementation used by Open edX.

Documentation

Configuration

In order to use edx-proctoring, you must obtain an account (and secret configuration - see below) with SoftwareSecure, which provides the proctoring review services that edx-proctoring integrates with.

You will need to turn on the ENABLE_SPECIAL_EXAMS in lms.env.json and cms.env.json FEATURES dictionary:

"FEATURES": {
    :
    "ENABLE_SPECIAL_EXAMS": true,
    :
}

Also in your lms.env.json and cms.env.json file please add the following:

"PROCTORING_SETTINGS": {
    "LINK_URLS": {
        "contact_us": "{add link here}",
        "faq": "{add link here}",
        "online_proctoring_rules": "{add link here}",
        "tech_requirements": "{add link here}"
    }
},

In your lms.auth.json file, please add the following secure information:

"PROCTORING_BACKENDS": {
    "software_secure": {
        "crypto_key": "{add SoftwareSecure crypto key here}",
        "exam_register_endpoint": "{add endpoint to SoftwareSecure}",
        "exam_sponsor": "{add SoftwareSecure sponsor}",
        "organization": "{add SoftwareSecure organization}",
        "secret_key": "{add SoftwareSecure secret key}",
        "secret_key_id": "{add SoftwareSecure secret key id}",
        "software_download_url": "{add SoftwareSecure download url}"
    },
    'DEFAULT': 'software_secure'
},

You will need to restart services after these configuration changes for them to take effect.

Email Templates

edx-proctoring provides generic base email templates that are rendered and sent to learners based on changes to the status of a proctored exam attempt. They have been designed such that you may leverage Django template inheritance to customize their content to the proctoring backend. Because proctoring backend plugins are installed in edx-platform, you must create an overriding template in the edx-platform repository. The template path should be emails/proctoring/{backend}/{template_name}. Note that your template can either completely override the base template in edx-proctoring, or it can extend the base template in order to leverage the existing content of the blocks within the base template, particularly if you only need to change a portion of the template.

Debugging

To debug with PDB, run pytest with the -n0 flag. This restricts the number of processes in a way that is compatible with pytest

pytest -n0 [file-path]

  • use the dropdown menu component on the Instructor Dashboard Proctored Exam Attempt panel for proctored exam attempts in the error state, providing the following options:

    • Resume, which transitions the exam attempt into the ready_to_resume state.

    • Reset, which behaves the same as the previous reset functionality, originally exposed via the [x] link.
