KON-118 Allow Nullable Expression Inside Assert Method

[igorwojda]

Allow nullable expressions inside assert and assertNot methods

The it.primaryConstructor is nullable:

Before

@Test
    fun `value class has parameter named 'value' 2`() {
        KoScope.fromProjectFiles()
            .classes()
            .withValueModifier()
            .assert { it.primaryConstructor?.hasParameterNamed("value") ?: false }  // <- HERE
    }

After

@Test
    fun `value class has parameter named 'value' 2`() {
        KoScope.fromProjectFiles()
            .classes()
            .withValueModifier()
            .assert { it.primaryConstructor?.hasParameterNamed("value") }  // <- HERE 
    }
