You misunderstood the sentence. I didn't say God's name was "testy." I said (and the scripture says) God called himself "I am who I am." Read Genesis again.
Hope this helps:
God appeared to Moses in the
burning bush and told him to go to Egypt to lead the Israelites out of slavery. In response, Moses said to God, “Suppose I go to the Israelites and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ Then what shall I tell them?” (

God said to Moses, “I AM WHO I AM. This is what you are to say to the Israelites: ‘I AM has sent me to you’” (
Exodus 3:14).
God gets a little testy when people are disobedient, as in the Garden of Eden when Adam and Eve broke the only law he ever gave them about not eating fruit from the Tree of the Knowledge of Good and Evil, and he ran them off to go anywhere but perfection with Adam having a future of hard work to make a living off the earth, and Eve being frightened of snakebites.

The devil was quick to respond that if God hadn't pampered Job so with wealth, a big, happy family, lots of livestock, and thousands of heads of livestock, Job would curse him if God took all his comforts away. Jeepers, the Democrats sound just like Satan, with Job being President Trump.
Anyway to prove his point, God turned over Job's welfare to
the Democrats , I mean, Satan, and told him to take all he wanted away, but he couldn't take away Job's life.
The rest of the story is here,
There was a man in the land of Uz, whose name was Job; and that man was perfect and upright, and one that feared God, and eschewed evil. And there were born unto him seven sons and three daughters. His substance also was seven thousand sheep, and three thousand camels, and five hundred yoke of...

and Job, good man that he was proved God was right through many hardships, loss of everything and everyone in his family, and his troubles start
here and go through chapter 42:
Bible Gateway passage: Job 1 - King James Version
Read it, and you tell me if God is testy, not just with men, but also with his adversary, Satan.
