Collection assertions

Arrays and Iterables

The following assertions work for Array and Iterable

theIntArray shouldContain 2
theIntArray shouldNotContain 10

theIntArray shouldContainSome arrayOf(1, 10, 15, 2)
theIntArray shouldContainNone arrayOf(5, 10, 11)

arrayOf(1, 2, 3) shouldBeEqualTo arrayOf(1, 2, 3)
arrayOf(4, 5, 6) shouldNotBeEqualTo arrayOf(7, 8, 9)

theIntArray.shouldBeEmpty()
theIntArray.shouldNotBeEmpty()

2 shouldBeIn arrayOf(1, 2, 3)
2 shouldNotBeIn arrayOf(4, 5, 6)

listOf(10, 15, 20) shouldContainAll listOf(10, 15, 20)
listOf(10, 15, 20) shouldNotContainAny listOf(5, 7)

listOf(1, 2, 3) shouldContainSame listOf(3, 1, 2)

In case of Array or Iterable contain Chars or CharSequences and do not care about the characters case you can use the following assertions:

listOf('abc', 'cda', 'FGT') shouldContainAllIgnoringCase listOf('AbC', 'cDa', 'fgT')
listOf('abc', 'cda', 'FGT') shouldNotContainAnyIgnoringCase listOf('ab', 'CD')

listOf('abc', 'cda', 'FGT') shouldContainSomeIgnoringCase arrayOf('AbC', 'cD', 'fg')

Maps

theMap shouldHaveKey "Name"
theMap shouldNotHaveKey "Age"

theMap shouldHaveValue "Peter"
theMap shouldNotHaveValue "Max"

theMap shouldContain ("Name" to "Peter")
theMap shouldNotContain ("Age" to 10)

theMap.shouldBeEmpty()
theMap.shouldNotBeEmpty()
