Run the 'UTBotJava' project in IntelliJ Idea 2022.1.4\r\n2. Install one of the latest from main branch\r\n3. Open test generation dialog for utbot-sample/src/main/java/org/utbot/examples/stream/BaseStreamExample.java\r\n4. Select returningStreamExample method\r\n5. click Generate Tests\r\n6. check generated tests\r\n\r\n**Expected behavior**\r\n\r\nNeed to compare expected and actual results for Streams in tests.\r\n\r\n**Actual behavior**\r\n\r\nThere are actual and expected Objects generated containing Streams. But they are not compared.\r\n\r\n**Visual proofs (screenshots, logs, images)**\r\n\r\n~~~java\r\npackage org.utbot.examples.stream;\r\n\r\nimport org.junit.jupiter.api.Test;\r\nimport org.junit.jupiter.api.DisplayName;\r\n\r\nimport java.util.ArrayList;\r\nimport java.util.List;\r\n\r\nimport static org.utbot.runtime.utils.UtUtils.createInstance;\r\n\r\npublic class BaseStreamExampleTest {\r\n    ///region Test suites for executable org.utbot.examples.stream.BaseStreamExample.returningStreamExample\r\n\r\n    ///region SYMBOLIC EXECUTION ENGINE: SUCCESSFUL EXECUTIONS for method returningStreamExample(java.util.List)\r\n\r\n    /**\r\n     * @utbot.classUnderTest {@link BaseStreamExample}\r\n     * @utbot.methodUnderTest {@link BaseStreamExample#returningStreamExample(List)}\r\n     * @utbot.executesCondition {@code (list.isEmpty()): True}\r\n     * @utbot.invokes {@code {@link List#stream()}}\r\n     * @utbot.returnsFrom {@code return list.stream();}\r\n     */\r\n    @Test\r\n    @DisplayName(\"returningStreamExample: list.isEmpty() : True -\u003e return list.stream()\")\r\n    public void testReturningStreamExample_ListIsEmpty() throws Exception {\r\n        BaseStreamExample baseStreamExample = new BaseStreamExample();\r\n        ArrayList list = new ArrayList();\r\n\r\n        Object actual = baseStreamExample.returningStreamExample(list);\r\n\r\n        Object expected = createInstance(\"java.util.stream.ReferencePipeline$Head\");\r\n    }\r\n\r\n    /**\r\n     * @utbot.classUnderTest {@link BaseStreamExample}\r\n     * @utbot.methodUnderTest {@link BaseStreamExample#returningStreamExample(List)}\r\n     * @utbot.executesCondition {@code (list.isEmpty()): False}\r\n     * @utbot.invokes {@code {@link List#stream()}}\r\n     * @utbot.returnsFrom {@code return list.stream();}\r\n     */\r\n    @Test\r\n    @DisplayName(\"returningStreamExample: list.isEmpty() : False -\u003e return list.stream()\")\r\n    public void testReturningStreamExample_NotListIsEmpty() throws Exception {\r\n        BaseStreamExample baseStreamExample = new BaseStreamExample();\r\n        ArrayList list = new ArrayList();\r\n        list.add(null);\r\n        list.add(null);\r\n        list.add(null);\r\n        list.add(null);\r\n        list.add(null);\r\n        list.add(null);\r\n        list.add(null);\r\n        list.add(null);\r\n        list.add(null);\r\n        list.add(null);\r\n\r\n        Object actual = baseStreamExample.returningStreamExample(list);\r\n\r\n        Object expected = createInstance(\"java.util.stream.ReferencePipeline$Head\");\r\n    }\r\n    ///endregion\r\n\r\n    ///endregion\r\n}\r\n~~~\r\n\r\n**Environment**\r\n\r\nWindows 10 Pro\r\nGradle\r\nJDK 11\r\n\r\n**Additional context**\r\n\r\nProbably related to #1034\r\n\r\nSame for DoubleStreamExample.returningStreamExample","author":{"url":"https://github.com/alisevych","@type":"Person","name":"alisevych"},"datePublished":"2022-09-30T15:02:31.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/1046/UTBotJava/issues/1046"}
