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

(11) Say: What thing is the weightiest in testimony? Say: Allah is witness between you and me; and this Quran has been revealed to me that with it I may warn you and whomsoever it reaches. Do you really bear witness that there are other gods with Allah? Say: I do not bear witness. Say: He is only one Allah, and surely I am clear of that which you set up (with Him).

(12) Then are they sent back to Allah, their Master, the True one; now surely His is the judgment and He is swiftest in taking account.

(13) Then when he saw the sun rising, he said: Is this my Lord? Is this the greatest? So when it set, he said: O my people! surely I am clear of what you set up (with Allah).

(14) Truly in the hereafter they are the greatest losers.

(15) Say: Shall We inform you of the greatest losers in (their) deeds?

(16) He said: They are here on my track and I hastened on to Thee, my Lord, that Thou mightest be pleased.

(17) And they desired a war on him, but We made them the greatest losers.

(18) They will not hear its faintest sound, and they shall abide in that which their souls long for.

(19) And it shall avert the chastisement from her if she testify four times, bearing Allah to witness that he is most surely one of the liars;

(20) These are they who shall have an evil punishment, and in the hereafter they shall be the greatest losers.
