not exists

[Daniel Sobral]

I'm looking for something like !xs.exists(p). I have code like this:

valuesA1B1 must not haveKeys("a2", "a3", "b2")

And then I found that if any of these keys are not present, then this is condition is true. I need to assert that *none* of these keys are present. Suggestions?

You can go:

forall(values) { v => Seq("a1", "a2", "a3") must not contain(v) }

Well, I suppose I can, but the failure message will be confusing.

You can go:

 Seq(1, 2, 3) must not(containAnyOf(Seq(1, 4)))

But the failure message will say:

List(1, 2, 3) contains at least one of '1, 4' 

 

Which is not super precise, I need the improve that.

Hi Daniel,

With the latest SNAPSHOT the message is:

x List(1, 2, 3) contains '1'

Cheers,

Eric.

It's better, but it doesn't work with keys. I'd have to transform the input to extract just the keys, which would obscure what is being checked.

 Hi Daniel,

In the latest 1.15-SNAPSHOT now the behaviour is more intuitive:

 Map(1 -> "1", 2 -> "2", 3 -> "3") must not haveKeys(1, 2)

> Map(1 -> 1, 2 -> 2, 3 -> 3) has the keys '1, 2'

Cheers,

Eric.

Well, but Map(1 -> "1", 3 -> "3") must not haveKeys(1, 2) succeeds, which is what I find non-intuitive. And, regardless of whether that's intuitive or not (honestly, I think this is the kind of situation that's too ambiguous to be sure), I still don't have anything that will do what I _need_ doing. :-)

Daniel, did you try it on the latest SNAPSHOT?

Because I get a failure:

x Map(1 -> 1, 3 -> 3) has the key '1'

Mmmmm. I thought I did, but it turns out the snapshot was not replaced due to Windows preventing the file from being removed because IntelliJ had it opened. Yes, it works exactly as I'd like it to now!
