The ONYX Testsuite facilitates the presentation of complex examination scenarios. Exams can be used in the context of the learning platform OPAL by integrating ONYX tests into courses. The course element Test also comes with a special exam mode.

More detailed information can be found on the OPAL help pages for the exam mode.

Configure exam mode


Exam browser

An exam browser allows the implementation of closed examination scenarios. When using the exam browser, the participant has only access to approved applications and functions. In the simplest case, the participant can only serve the exam application. Other browser pages, functions or system functions are not accessible.

For ONYX exams performed as part of the learning platform OPAL, the use of the open source system Safe Exam Browser (SEB) for closed examination scenarios by ETH Zurich is recommended. The exam browser SEB provides comprehensive security, and a special ID ensures that the exam can only be carried out in the SEB environment.

For more information, refer to the Guide to using the Safe Exam Browser (SEB).

Exam Mode

The exam mode allows authenticated users to monitor the examination.


For all participants who qualify to take the exam, the exam mode shows the current exam state:

  • The participant is not present.
  • The participant is waiting for the exam to start.
  • The participant is processing the exam.
  • The participant has restarted the exam.
  • The participant has completed the exam.
  • The participant has aborted the exam.

Using the exam mode, the supervisor has the opportunity to actively intervene in the examination process, which enables them to start or finish the exam for one or more participants. Exams can be configured in such a way so that they can only be started with the supervisor's manual approval. It is also possible to finish the exam for all participants at once.

More detailed information can be found on the OPAL help pages for the exam mode.

User identification during the exam

For reliable identification, the participant's name is permanently displayed on the screen during the exam. This extension affects in particular the examination execution in the Safe Examination Browser (SEB), with the participant's name from the learning platform now being permanently visible.

Client backup

The assessment function also ensures a client backup. In the event of a system error on the client, the examiner may allow to continue the exam on another computer and extend the processing time if necessary. Once approved, the participant can continue the exam on another device.

Progress is saved with every change so that a complete recovery can be guaranteed.

Server backup

Exam data is stored on the server in real time and regularly backed up to the learning platform. If the learning platform fails for technical reasons, the exam can still be completed using ONYX.

When the availability of the learning platform is restored, the data will be automatically saved. If there should be any problems with the transmission of the results, the answers can also be downloaded by the examinee and manually provided to the examiner.

Export PDF file

Exam content can be printed as a PDF file and used as a hardcopy test in an emergency situation.

The PDF document will be printed in A4 format following the ISO 216 standard.

For more information, refer to the help page Export test as PDF.

Backing up learner responses

Once the exam has been completed, the ONYX Player provides a document containing all the answers given by the learners. This summary lists all questions and answers by the learners in HTML format. The document also contains a checksum, which can be calculated using the HTML document (MD5 hash). The checksum serves as proof that the data has not been modified after the checksum was generated. An open-source-based validation tool will be provided for the exam within the learning platform (OPAL campus). The summary is also available in PDF format.
