Expected Behavior

Not detecting Unused Import

Observed Behavior

It is better to fix this code, but if you delete the import according to lint, a build error will occur.

                import com.foo.psi.Sealed
                import com.foo.psi.Sealed.SubClass

                fun main() {
                    listOf<Sealed>()
                    Sealed.SubClass()
                    SubClass()
                }

We can check this by adding this test.

    @Test
    fun `only redundant sealed sub class imports should be removed`() {
        assertThat(
            NoUnusedImportsRule().lint(
                """
                import com.foo.psi.Sealed
                import com.foo.psi.Sealed.SubClass

                fun main() {
                    listOf<Sealed>()
                    Sealed.SubClass()
                    SubClass()
                }
                """.trimIndent()
