Creating your Turnitin API key

Before installing this plugin firstly make sure you are logged in as an Administrator and that you are using Moodle 3.5 or higher.

To install, all you need to do is copy all the files into the plagiarism/turnitinsim directory on your Moodle installation. You should then go to "Site Administration" > "Notifications" and follow the on screen instructions.

Plagiarism plugins also need to be enabled before this plugin can be used. This should happen as part of the install process but if it doesn't then you can do this by going to "Site Administration" > "Advanced Features" and ticking the "Enable plagiarism plugins" checkbox before saving.

To configure the plugin go to "Site administration" > "Plugins" > "Plagiarism" > "Turnitin Integrity plagiarism plugin" and enter your API key and API URL.

Other options can also be set, such as which Moodle modules to enable the plugin for or logging. Logging can be useful in scenarios where there is a problem with your installation. Default settings for the plugin can also be enabled so that you don't have to configure every individual assignment each time.

This plugin contains a full suite of PHPUnit tests which can be run against your Moodle installation.

Provided your environment is already configured to run PHPUnit tests, then run the following command from the Moodle root directory:

vendor/bin/phpunit --testsuite plagiarism_turnitinsim_testsuite

Provided your environment is already configured to run Behat tests, you can download and install our behat tests from their repository by running the following command from the plugin root directory:

Then run the following command from the Moodle root directory:
