Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

6.7 Expector

Course subject(s) 6. Testing

Learn about the Expector tool, developed at the TU Delft, which helps us organize testing of our spreadheets.

At the TU Delft, testing of spreadsheets is but one of many testing related research activities. At TEDxDelft 2015 (a local TED conference), one of our Professors, Andy Zaidman, spoke about the importance of properly testing your software. In the area of software testing we also teach several courses in our Bachelor and Master programmes.

Sorry but there don't seem to be any downloads..
