I have a project I'm trying to unit test.
The tests run fine. The following code is a dummy test for brevity:
enum class QueryFilterOperator(val operator: String) {
EQUAL("="),
GREATER_THAN(">"),
LOWER_THAN("<"),
GREATER_THAN_OR_EQUAL(">="),
LOWER_THAN_OR_EQUAL("<=");
}
class QueryFilterOperatorTest : StringSpec({
"a query filter operator" {
assertEquals("=", EQUAL.operator)
}
})
But when trying to debug it using IntelliJ tooling, the compilation fails on some kapt generated code:
package com.wizy.data.contracts;
import java.lang.System;
@kotlin.Metadata(mv = {1, 1, 16}, bv = {1, 0, 3}, k = 1, d1 = {"\u0000\u0012\n\u0002\u0018\u0002\n\u0002\u0010\u0010\n\u0000\n\u0002\u0010\u000e\n\u0002\b\t\b\u0086\u0001\u0018\u00002\b\u0012\u0004\u0012\u00020\u00000\u0001B\u000f\b\u0002\u0012\u0006\u0010\u0002\u001a\u00020\u0003\u00a2\u0006\u0002\u0010\u0004R\u0011\u0010\u0002\u001a\u00020\u0003\u00a2\u0006\b\n\u0000\u001a\u0004\b\u0005\u0010\u0006j\u0002\b\u0007j\u0002\b\bj\u0002\b\tj\u0002\b\nj\u0002\b\u000b\u00a8\u0006\f"}, d2 = {"Lcom/wizy/data/contracts/QueryFilterOperator;", "", "operator", "", "(Ljava/lang/String;ILjava/lang/String;)V", "getOperator", "()Ljava/lang/String;", "EQUAL", "GREATER_THAN", "LOWER_THAN", "GREATER_THAN_OR_EQUAL", "LOWER_THAN_OR_EQUAL", "data-contracts"})
public enum QueryFilterOperator {
/*public static final*/ EQUAL /* = new EQUAL(null) */,
/*public static final*/ GREATER_THAN /* = new GREATER_THAN(null) */,
/*public static final*/ LOWER_THAN /* = new LOWER_THAN(null) */,
/*public static final*/ GREATER_THAN_OR_EQUAL /* = new GREATER_THAN_OR_EQUAL(null) */,
/*public static final*/ LOWER_THAN_OR_EQUAL /* = new LOWER_THAN_OR_EQUAL(null) */;
@org.jetbrains.annotations.NotNull()
private final java.lang.String operator = null;
@org.jetbrains.annotations.NotNull()
public final java.lang.String getOperator() {
return null;
}
QueryFilterOperator(java.lang.String operator) {
}
}
In this code, we can see that the enum constructors are not set correctly.
If I remove the constructor and try again (using an admittedly even dummier test), I can debug as intended.
enum class QueryFilterOperator {
EQUAL,
GREATER_THAN,
LOWER_THAN,
GREATER_THAN_OR_EQUAL,
LOWER_THAN_OR_EQUAL;
}
class QueryFilterOperatorTest : StringSpec({
"a query filter operator" {
assertNotEquals(EQUAL, GREATER_THAN)
}
})
Why is kapt behaving this way ? Why does it complain only when debugging? Why does it even generate this obviously incorrect java code?
Here is the kapt configuration in the POM:
