''Test Of Humanity'' is a ''VideoGame/{{Portal 2}}'' fanfic written by Baronobeefdip.

In the fic, a bored GLaDOS decides to see if she can implant a core's mind into a human body and how long they can survive. After a brief moment of sifting through cores that won't work for her experiments (for various reasons), she decides to bring back Wheatley from space and implant his robotic "brain" into that of a human test subject.

What follows next is Wheatley learning to adapt to human life, his reunion with Chell, and his developing feelings towards her. However, GLaDOS has her own sinister plans in mind.

A [[http://www.fanfiction.net/s/7046503/1/Test_Of_Humanity_2 sequel]] is also in the works, but is on hiatus due to the author having writer's block and dealing with RealLife stress at the moment.

Tropes associated with this fic:

* {{Adorkable}}: Wheatley in his human body. He's tall, wears glasses, is rather clumsy, tends to ramble, and is rather chubby. Yet, he's also compassionate and friendly towards others. It's one of the reasons Chell [[spoiler: starts to fall in love with him.]]
* AirVentPassageway: Well, more like "Incinerator Exhaust-Pipe Escape". Subverted in that [[spoiler:Wheatley's too fat to fit all the way through.]]
* AuthorAppeal: Baronobeefdip is a fan of weight-gain fics. Guess what [[FetishFuel happens to Wheatley]] throughout the story (and on into the sequel)?
* BalloonBelly: Happens to Wheatley twice. First when he gorges himself on the food in Chell's fridge, and second when [=GLaDOS=] tricks him into eating 30 cakes. Subverted in that he doesn't instantly lose the extra weight.
** In the sequel, it's stated that he's actually gotten even ''fatter'' since then.
* BerserkButton: As usual, don't call Wheatley a "moron". Also, don't ever compare him to HAL or [=GLaDOS=]--and hurting Chell is a very, ''very'' bad idea. [[spoiler: GLaDOS]] finds this out the hard way.
* BewareTheNiceOnes: Wheatley is usually a friendly if dim-witted GentleGiant cyborg. But, push his BerserkButton too many times and he won't hesitate to (literally) throw his weight around.
* BigEater: Wheatley's got a rather large appetite. At one point in the fic, he ate 30 cakes before passing out.
** And in the sequel, it's stated that Chell's roommates can't figure out what to cook for dinner because Wheatley ate nearly everything.
* ChekhovsGun: Wheatley's weight gain at first seems insignificant; [[spoiler: it's what ultimately causes him to defeat GLaDOS, due to him getting stuck in a pipe and causing an explosion.]]
* CyberCyclops: Subverted with Wheatley. He is technically a cyborg (Due to being a robotic brain controling a human body), but he has two eyes. He is, however, blind in one eye after [[spoiler:being caught in an explosion.]]
* DisneyDeath: [[spoiler: Wheatley]]
* FatAndProud: While he doesn't outright say it, Wheatley seems to be quite content with his weight.
* HowDareYouDieOnMe: [[spoiler: Chell to Wheatley, after [=GLaDOS=]'s exhaust pipe explodes with him in it. "GET UP! D-DON'T DIE ON ME, YOU MORON!"]]
* [[{{FanBoy}} Fan Girl]]: [=GLaDOS=] is a HAL fan girl. [[SarcasmMode Who would have guessed it?]]
* FatBastard: Averted with Wheatley. (He can be rude, but never ''intentionally'' so.)
* FatIdiot: Wheatley (though he was dim-witted ''before'' putting on weight).
* GentleGiant: Wheatley is stated to tower over people in his human body and becomes rather overweight by the end of the fic. Yet, he's shown to be rather peaceful in nature.
** Chell even refers to him as a "gentle giant" in the sequel, thinking of how he's large enough to harm anyone who crosses him, yet he won't even hurt a fly (literally--he just watches it buzz around for a while).
* HoistByHisOwnPetard: GLaDOS really shouldn't have fattened Wheatley up like that, or tortured him and Chell.
* HugeGuyTinyGirl: Chell is an average-sized human being, whereas Wheatley is a rather large cyborg.
* NakedFirstImpression: After showering for the first time, Wheatley walks out of the bathroom dripping wet and nude to ask Chell for clean clothes...in front of her roommates.
* NotSoDifferent: [=GLaDOS=] uses this to torture Wheatley by showing how he's similar to herself and HAL. It works (but only for a while).
* PaperThinDisguise: When Atlas and P-Body venture into town [[spoiler: to capture Chell]], they disguise themselves with a [[ConspicuousTrenchcoat trenchcoat and fedora]] they found in the trash. And ''it works.''
* TheReasonYouSuckSpeech: [=GLaDOS=]'s speech to Wheatley about how Chell would never love a "machine living a lie" (and the NotSoDifferent aspects mentioned above).
* ShutUpHannibal: Wheatley literally tells [=GLaDOS=] to shut up [[spoiler: and punches her in the eye]].
* StoutStrength: Wheatley punches GLaDOS [[spoiler: hard enough to break her eye (and shatters his arm in the process)]].
* TakeThat: [[WordOfGod Baronobeefdip]] has stated that one of the reasons why she made Wheatley overweight in her fic is because she was tired of everyone portraying [[FanNickname Human!Wheatley]] as a Creator/StephenMerchant clone, believing that the fandom cared more about making Wheatley "a sex symbol" rather than loving him for his clumsy yet well-meaning personality.
