Add file `DeepNested.java` into `utbot-sample/src/main/java/org/utbot/examples/inner/` with the following content:\r\n\r\n```Java\r\npackage org.utbot.examples.inner;\r\n\r\npublic class DeepNested {\r\n    public class Nested1 {\r\n        public class Nested2 {\r\n            public int f() {\r\n                return 0;\r\n            }\r\n        }\r\n    }\r\n}\r\n```\r\n\r\n2. Add file `DeepNestedTest.kt` into `utbot-summary-tests/src/test/kotlin/examples/inner/` with the following content:\r\n\r\n```Kotlin\r\npackage examples.inner\r\n\r\nimport examples.SummaryTestCaseGeneratorTest\r\nimport org.junit.jupiter.api.Test\r\nimport org.utbot.examples.DoNotCalculate\r\nimport org.utbot.examples.inner.DeepNested\r\nimport org.utbot.framework.plugin.api.MockStrategyApi\r\n\r\nclass DeepNestedTest : SummaryTestCaseGeneratorTest(\r\n    DeepNested::class,\r\n) {\r\n    @Test\r\n    fun testF() {\r\n        val summary1 = \"Test returns from: return 0;\"\r\n\r\n        val method = DeepNested.Nested1.Nested2::f\r\n        val mockStrategy = MockStrategyApi.NO_MOCKS\r\n        val coverage = DoNotCalculate\r\n\r\n        val summaryKeys = listOf(\r\n            summary1\r\n        )\r\n\r\n        summaryCheck(method, mockStrategy, coverage, summaryKeys)\r\n    }\r\n}\r\n```\r\n\r\n**Expected behavior**\r\n\r\nTest passes, as corresponding summaries are generated for tests for `A.B.C.f()`\r\n\r\n**Actual behavior**\r\n\r\nTest fails because no summaries are generated.\r\n\r\n**Visual proofs (screenshots, logs, images)**\r\n\r\nTest fails with assertion message\r\n\r\n```\r\nThe following comments were produced by the UTBot, but were not found in the list of comments passed in the check() method:\r\n\r\n-------------------------------------------------------------\r\n\r\nnull-------------------------------------------------------------\r\n\r\n\r\nThe following comments were passed in the check() method, but were not found in the list of comments produced by the UTBot:\r\n\r\n-------------------------------------------------------------\r\n\r\nTest returns from: return 0;\r\n-------------------------------------------------------------\r\n```\r\n\r\n\r\n\r\n**Environment**\r\n\r\nNothing specific.\r\n\r\n**Additional context**\r\n\r\nFor me it seems that problem is in `org.utbot.summary.ast.SourceCodeParser#traverseInnerClassDeclarations` and the fact that it doesn't make any recursive calls.\r\n","author":{"url":"https://github.com/volivan239","@type":"Person","name":"volivan239"},"datePublished":"2022-08-11T10:24:32.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/710/UTBotJava/issues/710"}
