There are a LOT more than you'd think. Wiki refers to the most common, the less common and then those which were in development but never made it to market:

Those you will be familiar with are (available from most sources):
Testosterone caproate (component of Omnadren and Triormon Depositum)
Testosterone cypionate (Depo-Testosterone, numerous others)
Testosterone decanoate (component of Sustanon 250)
Testosterone enanthate (Delatestryl, numerous others) (component of Testoviron Depot)
Testosterone isobutyrate (Agovirin-Depot, Perandren M, Testocryst, Virex-Cryst; component of Femandren M/Folivirin)
Testosterone isocaproate (component of Omnadren, Sustanon 100, and Sustanon 250)
Testosterone phenylpropionate (component of Omnadren, Sustanon 100, and Sustanon 250)
Testosterone propionate (Testoviron, numerous others) (component of Omnadren, Sustanon 100, Sustanon 250, and Testoviron Depot)
Testosterone undecanoate (Aveed, Andriol, Nebido, Jatenzo, numerous others)

The less common (more likely to be seen in medical and veterinary use). Some marketed but not successful:
Testosterone acetate (Aceto-Sterandryl, Aceto-Testoviron, Amolisin, Androtest A, Deposteron, Farmatest, Perandrone A)
Testosterone cyclohexylpropionate (Andromar, Femolone, Telipex Retard; component of Trioestrine Retard)
Testosterone enantate benzilic acid hydrazone (component of Climacteron)
Testosterone furoate (Furotest)
Testosterone hexahydrobenzoate (Sterandryl Retard; component of Trinestril AP)
Testosterone hexahydrobenzylcarbonate (Lontanyl)
Testosterone hexyloxyphenylpropionate (Andradurin)
Testosterone ketolaurate (Androdurin; component of Testosid-Depot and Klimanosid R-Depot)
Testosterone nicotinate (Bolfortan, Linobol)
Testosterone phenylacetate (Perandren, Androject)
Testosterone phosphate (Telipex Aquosum)
Testosterone undecylenate (component of Durasteron and Triolandren)
Testosterone valerate (component of Deposterona and Triolandren)[3]

Those you almost certainly never heard of (never went to market:
estosterone buciclate (20 Aet-1, CDB-1781) – a very long-acting testosterone ester that was under development but ultimately did not reach the market[4][5]
Polytestosterone phloretin phosphate
Testosterone 17β-(1-((5-(aminosulfonyl)-2-pyridinyl)carbonyl)-L-proline) (EC586)[6][7]
Testosterone acetate butyrate
Testosterone acetate propionate
Testosterone benzoate
Testosterone butyrate
Testosterone diacetate
Testosterone dipropionate
Testosterone formate
Testosterone isovalerate
Testosterone palmitate
Testosterone phenylbutyrate
Testosterone stearate
Testosterone succinate
Testosterone sulfate

And that's not even the full list lol.

The reason why many never 'made it' is the more well known did the job they were created for (medically usually) better. I believe the full list is over 100 (close to 120).
