Run a project in IntelliJ Idea 2022.1.3  - 2022.2.2\r\n2. Install [RC plugin build](https://github.com/UnitTestBot/UTBotJava/actions/runs/3217740096) \r\n3. Set Fuzzing to 100% (in File -\u003e Settings -\u003e Tools -\u003e  UnitTestBot)\r\n4. Generate tests with UnitTestBot for utbot-sample/src/main/java/org/utbot/examples/mock/MockRandomExamples.java\r\nfor useSecureRandom() - check Mock everything outside class. \r\n\r\n**Expected behavior**\r\n\r\nThere should be only valid tests generated.\r\n\r\n*Possible solutions*\r\n\r\nFuzzer can use mock Random(?)\r\nGenerated tests should be double-checks that they return same results(?)\r\nother solution(?)\r\n\r\n**Actual behavior**\r\n\r\nFuzzing is generating a test for Random without mocks. It asserts the value returned by Random and fails.\r\n\r\n**Visual proofs**\r\n\r\nThe following test is generated by Fuzzer:\r\n\r\n```java\r\n    ///region FUZZER: SUCCESSFUL EXECUTIONS for method useSecureRandom()\r\n\r\n    @Test\r\n    @DisplayName(\"useSecureRandom: arg_0 = MockRandomExamples() -\u003e return 1\")\r\n    public void testUseSecureRandomReturnsOne() {\r\n        MockRandomExamples mockRandomExamples = new MockRandomExamples();\r\n\r\n        int actual = mockRandomExamples.useSecureRandom();\r\n\r\n        assertEquals(1, actual);\r\n    }\r\n    ///endregion\r\n\r\n```\r\n\r\n**Environment**\r\n\r\nWindows 10 Pro\r\nIntelliJ IDEA 2022.2.2\r\n\r\n**Additional context**\r\n\r\n_Originally posted by @alisevych in https://github.com/UnitTestBot/UTBotJava/issues/1102#issuecomment-1269804477_\r\n      ","author":{"url":"https://github.com/alisevych","@type":"Person","name":"alisevych"},"datePublished":"2022-10-11T13:02:51.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/1135/UTBotJava/issues/1135"}
