A Test Subject is a human, animal or robotic individual used by Aperture Science in their computer-aided Enrichment Center. Test Subjects are always represented as genderless black stick figures, nicknamed "Bendy.".
- Test Subjects are part of Aperture Science's 'Portal' project, for which they test the Aperture Science Handheld Portal Device in puzzles in the Enrichment Center's Test Chambers. However, Military Androids, also used as Test Subjects before being commercialized, appear not to use the ASHPD.
- While most of the time Test Subjects are human individuals, Aperture has been known to use animals (such as chickens), as well as robots (such as ATLAS, P-Body and the Military Androids).
- Before performing the proper ASHPD test, applying Test Subjects are to fill the Enrichment Center Test Subject Application Process, a 50-question computer-managed questionnaire.
- Test Subjects are also required to answer essay questions, like Essay Question 1-A: "Why should Aperture Science accept you as a research volunteer and would anyone file a police report if you went missing?"
- While common scientific / medical research made on humans is never directly dangerous, the ASHPD tests can be very dangerous, and can often result in the death of an unwary Test Subject. The hazards met include vaporization caused by High Energy Pellets, death by bullets from Sentry Turrets, falling in toxic liquid, being burned alive (by falling in an Emergency Intelligence Incinerator, or, in the case of Chell, by being purposefully killed by GLaDOS), being hurt by falling objects such as Weighted Storage Cubes, and being crushed by pistons (only in maintenance areas, if the Test Subject escapes).
- Human Test Subjects are fitted with Advanced Knee Replacement to slow down their falls, primarily to protect expensive testing equipment rather than the Test Subjects.
- According to GLaDOS, Aperture Science's annual bring-your-daughter-to-work day "is the perfect time to have [one's daughter] tested", suggesting Test Subjects are (at least partially) chosen among daughters of Aperture employees. Other popular Aperture Science Test Subject gathering methods include paying homeless people insignificant wages, forcing employees to participate in tests, picking up orphans from orphanages or transferring psychiatric patients from Aperture-branded mental institutions.
- ASHPD tests allowed Aperture Science to discover that Test Subjects, when confronted with science, may exhibit any or all of the following personality flaws: cowardice, impaired motor skills, poor judgement, fear of heights, weights, depths, bullets, and fire.
- According to Wheatley in Portal 2, the Enrichment Center has held over 10,000 test subjects.
- Other subjects' Relaxation Center Chambers and a small description about the subject such as their age, body type, gender, and height can be seen in the Aperture Science Extended Relaxation Center. However, it seems most of these test subjects have "expired" according to the label.

As of the events of Portal 2, both Wheatley and GLaDOS imply that Chell is the last surviving Test Subject of the 10,000 residents that were stored there before the enrichment center was locked down. Shortly before GLaDOS' murder at the hands of Chell, a robotic replacement program was being developed to render Chell and any human-based test subjects as unnecessary and irrelevant. However, during the co-op campaign, ATLAS and P-body discover a room full of humans in suspended animation, apparently giving the facility even more subjects to test. Later, in Art Therapy co-op course, GLaDOS admits that all the humans had died during her failed attempts at turning them into "killing machines".
- In the Portal series, the playable characters are always Test Subjects.
- The track "Subject Name Here" in the Portal soundtrack is a reference to the GLaDOS' quote, "Unbelievable ! You, [Subject Name Here], must be the pride of [Subject Hometown Here]." said at the completion of Test Chamber 06.
