Security Model

Details of the Platform credentials, including its profile if a request has been made for a copy.

Sample Content

This tab is available when the Test Tool is opened by a ContentItemSelectionRequest, ContentItemUpdateRequest or LtiDeepLinkingRequest message. It allows pre-defined content-items to be selected for return to the Platform, or for a bespoke item to be created.

Service

A drop-down menu of the services supported by the Test Tool; any not made available by the Tool Consumer will not be fully populated with details. Select a service to send requests to the Platform. Click the View last service request button to view the last request sent and the response received.

Options

Open the Options form (see below). Use the drop-down menu to access the Sign in window (see below).

Save

Click the button to save all changes to the current session, or use the drop-down menu:

Reload without saving

Used to refresh the system, clearing any changes made since the last save.

Save again

Used to update the system when the Save button is disabled.

Start new session

This will clear the system and reset all values to their defaults.

Display optional features?

Select to show any feature which is flagged as optional; e.g., those parameters which are neither required nor recommended.

Display unofficial extensions?

Select to show features which have been published but are not part of the 1EdTech specification.

Enable unpublished LTI features?

This option enables features which are still under development by 1EdTech and subject to change.

Enable experimental features?

These are extensions which are not expected to become part of the LTI specification at this time.

Disable prompt to display service request messages?

When selected, the prompt to display the message after it has completed will not appear.

Automatically display service request messages?

When selected, the service message will automatically be displayed when it has completed.

Apply some leniency to LTI conformance checks?

Accept messages which are not fully compliant with the LTI specification.

Disable third party cookie check?

Avoid check for third party cookies being blocked so opening a tool is never forced into a new window. (Note that if cookies are being blocked it is likely that this option will always revert to its default value of making the check.)

This tab summarises the message received which opened the system.

Summary

This section identifies the message URL, LTI version, message type, security profile used and whether the signature was verified. If the Platform provided a return URL, links are also displayed which allow this link to be followed with all combinations of return message and log entry.

Services Available

A list of services supported by the Test Tool Consumer is displayed with those made available in the message received from the Tool Consumer marked with a tick; all others are marked with a cross. All available services can be accessed directly by clicking on their name.

Initiate Login

For an LTI 1.3 message, this section shows the original initiate login request and the authentication request sent in response.

Message Parameters/Raw POST Parameters

This section lists the POST parameters received from the Platform.

JWT

When LTI parameters are passed as claims in a JWT, this section lists the headers and payload of the JWT.

Message Parameters (derived from JWT)

This section is displayed a JWT has been passed by the Platform and represents the LTI parameters which are equivalent to the claims received.

Message Claims (derived from message parameters)

This section lists the LTI claims which are equivalent to the message parameters. Each claim is listed in its fully expanded form which may differ from how it appears in the JWT section.

Message JWT (derived from message parameters)

This section displays the JWT which is equivalent to the LTI message parameters listed in the Message Parameters section.

This tab displays the credentials and security profile used for connections with the Platform. These values are used when sending service requests to the Platform. Changing them allows invalid requests to be tested. For LTI 1.3 connections, the tab also displays the configuration details for the tool; the public keyset URL or public key should be shared with the platform. The details shared by the platform should be configured on this tab as well.

If a profile has been obtained from the platform it will be also be displayed on this tab.

This tab is displayed for ContentItemSelectionRequest, ContentItemUpdateRequest or LtiDeepLinkingRequest messages. You can use it to select sample content-item(s) to be returned to the Platform, or to create a bespoke item. Messages to be returned with the items can also be added.

This menu lists all the services supported by the Test Tool. Selecting a service from the menu will display the settings relevant to its use, including the endpoint(s). The settings page can be used to send requests to the Platform; use the View last service request button to inspect the last request made and response received. When using LTI 1.3, the OAuth 2 Access Token service should be used first to obtain an access token for the required service scopes.

This system uses sessions to manage your activity; these sessions last for at least 2 hours. However, when a new session is started some endpoints may change and so any existing integrations you are testing may require updating. Signing into the system using a Google ID allows you to have a static set of endpoints to avoid this issue. It also provides the following options:

• backup the current configuration to local file;
• restore a previously backed-up configuration from a local file;
• automatically save your session to the server
• automatically log into the system and restore the last saved session
• manage a set of LTI 1.3 platform configurations (see below)

The only data shared by this process is your email address and your ID number as supplied by Google.

To aid the re-use of an LTI 1.3 platform, it is possible to save a configuration and have it associated with your Google ID. By default each Google ID can have up to 5 saved platform configurations (use the Feedback option on the Help to enquire about increasing this limit if it is not sufficient for your needs).

To save a configuration, just enter its details into the fields on the Security Profile page and click on the Save button in the header of the Platform Details section. If a platform with the same Platform ID, Client ID and Deployment ID is already defined, its details will be updated with the new values. If the deployment ID is left empty, an incoming message from the specified platform ID and client ID will be accepted with any deployment ID.

The Registered platforms button opens a list of all the existing configurations which have been saved; full details can be displayed by clicking on the plus sign at the start of the row. Initially a configuration is given a name of Unnamed; click on the name to change it. A configuration can be made available for use by other users by turning on its Public setting. Click on the download icon in the Action column to copy the configuration settings to the Security Profile page. (A configuration can also be copied by selecting its name from the drop-down list on the Registered platforms button.) Click on the delete button to remove the configuration.
