How is it possible to test this class?

data class BreakdownEntry(val category: Category, val childList: List<BreakdownEntry>, val amount: Double, val currencyCode: String, var percent: String = "")

If, for example, it was used as Serializable then I would take the given class as a basis and put some data for variables on it, and then check if the data that I recorded is correct.

here, when I try to create an object, I need to go along with all these parameters to the object at once, brr.

    Well, you can check that the fields of the objects do not match, each time creating with different parameters:

     @Test @Throws(Exception::class) fun testModelClass() { val category1 = Category().setGuid("category1").save() val category2 = Category().setGuid("category2").save() val breakdownEntry1 = BreakdownEntry(category1, emptyList(), 0.0, "", "") val breakdownEntry2 = BreakdownEntry(category2, emptyList(), 0.0, "", "") assertFalse(breakdownEntry1 == breakdownEntry2) assertFalse(breakdownEntry1.hashCode() == breakdownEntry2.hashCode()) }

    Also, if you wish, you can simply set some parameter to the percent parameter, then compare it with the initial object.
