Iterate List of Object in Kotlin TestCase - unit-testing

Question

I'm using Unit Test using Kotlin and unable to iterate List of Objects in my Test Case, Kindly check my below Coding,
#Test
#WithMockOAuth(siteId = "5698965", subPermissions = [SubPermission.GETD])
fun `get fee zero`() {
val body = """
{
"newMessage": {
"call": true,
"callMessatgeCount": 3,
"discounted": 2,
"NewFees": 4.99,
"Id" : "extra SIM Business"
}
}
""".trimIndent()
this.server.expect(requestTo("${integrationClientProperties.url}/main/0767777777/register/"))
.andRespond(withSuccess(body, MediaType.APPLICATION_JSON_UTF8))
assertThat(service.getValues("0767777777"))
.hasSize(3)
.first()
.hasFieldOrPropertyWithValue("callMessatgeCount", 3)
.hasFieldOrPropertyWithValue("NewFees", BigDecimal.ZERO)
this.server.verify()
}
Above i can able to check hasFieldOrPropertyWithValue for the first() element, As hasSize(3) i need to check all the 3 values which is List of Objects in the same TestCase method.
List of objects as Below
ListValue:[
{
"newMessage": {
"call": true,
"callMessatgeCount": 3,
"discounted": 2,
"NewFees": 4.99,
"Id" : "extra SIM Business"
},
{
"newMessage": {
"call": true,
"callMessatgeCount": 3,
"discounted": 2,
"NewFees": 0,
"Id" : "extra SIM Business"
},
{
"newMessage": {
"call": true,
"callMessatgeCount": 3,
"discounted": 2,
"NewFees": 4.99,
"Id" : "extra SIM Business"
}
]
Note: I tried element(index) to check the list of objects using multiple test cases.
Updated
Library" org.assertj.core.api.Assertions and supports java8

Assuming you are using AssertJ from the method names and that you have a Java-8-supporting version (i.e. 3.5+), you can find the allSatisfy method:
Verifies that all the elements satisfy given requirements expressed as a Consumer.
This is useful to perform a group of assertions on elements.
From the docs, something like the following should work
assertThat(service.getValues("0767777777"))
.hasSize(3)
.allMatch { assertThat(it)
.hasFieldOrPropertyWithValue("callMessatgeCount", 3)
.hasFieldOrPropertyWithValue("NewFees", BigDecimal.ZERO)
}
You could look into Kotlin-specific libraries as well (especially if you need to compile to JVM 6).
