itemIndexOf, itemLastIndexOf matchers

[jeromedecoster]

Hello,

I don't know if it's possible with the actual base Matchers, but it could be usefull to have something like this :

itemIndexOf, itemLastIndexOf

// I don't know if it's the best implementation :
assertThat(["a", "b", "c"], itemIndexOf("b", equalTo(0))) // FALSE
assertThat(["a", "b", "c"], itemIndexOf("b", lessThanOrEqualTo(1))) // TRUE
assertThat(["a", "b", "c"], itemIndexOf("e", equalTo(-1))) // TRUE

Usefull to :

• test position an item in an array ("b" at [1])
• test a position of 2 items in an array ("a" before "b")

Thanks !

I like this, and it is not possible with the existing matchers. Names will probably be indexOf() and lastIndexOf() to be similar to the Array/String methods of the same names.

assertThat(["a", "b", "c"], indexOf("b", equalTo(1)));
assertThat(["a", "b", "c"], indexOf("b", lessThanOrEqualTo(1)));
assertThat(["a", "b", "c"], indexOf("e", -1));
assertThat(["a", "b", "b"], lastIndexOf("b", greaterThanOrEqualTo(2)));

Hey cool :)

If i'm not wrong, it miss a Matcher with 2 parameters ?

something like "CompareMatcher" or "CombinedMatcher" (I don't know if it's the best implementation) :
public class CompareMatcher implements Matcher
{
public function CompareMatcher(obj1:Object, obj2:Object)

What do you think ?
