Programming is like getting a crush.
When you couldn't turn her on, you never figure out why.
Even if you did it, you still cannot believe why it could succeed all in a sudden.

The first time you did a unit test
is when you asked if she is okay
for a date; step by step,
In order not to break.
First, ask if she is free; Then, if she really need to eat,
she said OK there.

But, finally she didn't turn up
Integration test failed.
She was such a bitch.
