How should I use the infix fun <T> T.should(matcher: (T) -> Unit) ? What's its purpose ?
I use it like this :

person.should {
    it.firstName shouldBe "John"
    it.lastName shouldBe "Doe"
}

But that should seems redondant to me.

shouldBe checks for equality, should accepts a matcher. So you can write things like:
aNumber shouldBe lessThan 4

https://github.com/kotlintest/kotlintest/blob/master/doc/matchers.md here are the matchers. I believe most, if not all, of them can be separated, so if you see str.shouldHaveLineCount(count) then you can write str should haveLineCount(count) as well

That's correct.

We usually have extensions and infix functions for every matcher
