The word(s) "test" appears 29 time(s) in 28 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Nay! do you say that Ibrahim and Ismail and Isaac and Yaqoub and the tribes were Jews or Christians? Say: Are you better knowing or Allah? And who is more unjust than he who conceals a testimony that he has from Allah? And Allah is not at all heedless of what you do.

(2) But he who fears an inclination to a wrong course or an act of disobedience on the part of the testator, and effects an agreement between the parties, there is no blame on him. Surely Allah is Forgiving, Merciful.

(3) O you who believe! when you deal with each other in contracting a debt for a fixed time, then write it down; and let a scribe write it down between you with fairness; and the scribe should not refuse to write as Allah has taught him, so he should write; and let him who owes the debt dictate, and he should be careful of (his duty to) Allah, his Lord, and not diminish anything from it; but if he who owes the debt is unsound in understanding, or weak, or (if) he is not able to dictate himself, let his guardian dictate with fairness; and call in to witness from among your men two witnesses; but if there are not two men, then one man and two women from among those whom you choose to be witnesses, so that if one of the two errs, the second of the two may remind the other; and the witnesses should not refuse when they are summoned; and be not averse to writing it (whether it is) small or large, with the time of its falling due; this is more equitable in the sight of Allah and assures greater accuracy in testimony, and the nearest (way) that you may not entertain doubts (afterwards), except when it is ready merchandise which you give and take among yourselves from hand to hand, then there is no blame on you in not writing it down; and have witnesses when you barter with one another, and let no harm be done to the scribe or to the witness; and if you do (it) then surely it will be a transgression in you, and be careful of (your duty) to Allah, Allah teaches you, and Allah knows all things.

(4) And if you are upon a journey and you do not find a scribe, then (there may be) a security taken into possession; but if one of you trusts another, then he who is trusted should deliver his trust, and let him be careful (of his duty to) Allah, his Lord; and do not conceal testimony, and whoever conceals it, his heart is surely sinful; and Allah knows what you do.

(5) Say: O Allah, Master of the Kingdom! Thou givest the kingdom to whomsoever Thou pleasest and takest away the kingdom from whomsoever Thou pleasest, and Thou exaltest whom Thou pleasest and abasest whom Thou pleasest in Thine hand is the good; surety, Thou hast power over all things.

(6) Then after sorrow He sent down security upon you, a calm coming upon a party of you, and (there was) another party whom their own souls had rendered anxious; they entertained about Allah thoughts of ignorance quite unjustly, saying: We have no hand in the affair. Say: Surely the affair is wholly (in the hands) of Allah. They conceal within their souls what they would not reveal to you. They say: Had we any hand in the affair, we would not have been slain here. Say: Had you remained in your houses, those for whom slaughter was ordained would certainly have gone forth to the places where they would be slain, and that Allah might test what was in your breasts and that He might purge what was in your hearts; and Allah knows what is in the breasts.

(7) And test the orphans until they attain puberty; then if you find in them maturity of intellect, make over to them their property, and do not consume it extravagantly and hastily, lest they attain to full age; and whoever is rich, let him abstain altogether, and whoever is poor, let him eat reasonably; then when you make over to them their property, call witnesses in their presence; and Allah is enough as a Reckoner.

(8) O you who believe! call to witness between you when death draws nigh to one of you, at the time of making the will, two just persons from among you, or two others from among others than you, if you are travelling in the land and the calamity of death befalls you; the two (witnesses) you should detain after the prayer; then if you doubt (them), they shall both swear by Allah, (saying): We will not take for it a price, though there be a relative, and we will not hide the testimony of Allah for then certainly we should be among the sinners.

(9) Then if it becomes known that they both have been guilty of a sin, two others shall stand up in their place from among those who have a claim against them, the two nearest in kin; so they two should swear by Allah: Certainly our testimony is truer than the testimony of those two, and we have not exceeded the limit, for then most surely we should be of the unjust.

(10) This is more proper in order that they should give testimony truly or fear that other oaths be given after their oaths; and be careful of (your duty to) Allah, and hear; and Allah does not guide the transgressing people.
