• Clone or reuse UTBot project (https://github.com/UnitTestBot/UTBotJava.git)
• Open the project in the IDE
• Install the downloaded plugin

Go through manual scenarios

	Pre-condition	Condition	Class under test	Output
1	No UtUtils class	Generate a test class, that does not need utility methods	IntExamples.java	No UtUtils class is produced.
2	No UtUtils class	Generate a test class, that (a) needs a utility method, (b) does not use mocking	QueueUsages.java	Regular UtUtils class (without mocking support) is produced.
3	Regular UtUtils class (without mocking support) exists	Generate a test class, that (a) needs a utility method, (b) uses mocking	CommonMocksExample.java	UtUtils class with mocking support is produced.
4	UtUtils class with mocking support exists	Generate a test class, that (a) needs a utility method, (b) does not use mocking	QueueUsages.java	UtUtils class with mocking support from the previous generation stays the same.
5	UtUtils class with mocking support exists	Generate another test class, that (a) needs a utility method, (b) does not use mocking + create and choose another Test sources root: utbot-sample/src/test/java2	QueueUsages.java	No additional UtUtils class is generated in utbot-sample/src/test/java2. UtUtils class with mocking support from the previous generation stays the same.
6	No UtUtils class (delete previously generated test classes and UtUtils classes)	Generate a test class, that (a) does not need utility methods (b) uses mocking	MockRandomExamples.java and choose the method randomAsParameter() for test generation	No UtUtils class is produced.

IDEA interaction checks

• Gradle / Maven / IntelliJ
• in new test sources root
• in test sources root in other module
