Context

We have created a spring boot jdk project. We are using log4j library to record logs. While generating test case for the class , exception is being raised .

It is a gradle project .

Steps to Reproduce

Please break down here below all the needed steps to reproduce the issue. [If possible, please upload an example of the project you are generating tests for.]

  1. Create a spring boot , java gradle project
  2. Create a controller class . Also add looging using log4j library.
  3. Build the project
  4. Execute below command
    $EVOSUITE -class com.poc.controller.RecipeController -projectCP build/classes/java/main

EvoSuite Arguments

$EVOSUITE -class com.poc.controller.RecipeController -projectCP build/classes/java/main

Current Result

$EVOSUITE -class com.poc.controller.RecipeController -projectCP build/classes/java/main

Expected result

Should be able to resolve third party dependencies and generate test scenario.

You need to tell EvoSuite where to find all the dependencies -- EvoSuite assumes that all dependences are already on the classpath. This means that either you need to provide a full classpath (including all jar dependencies) to the -projectCP option, or use $EVOSUITE -setup to tell it where to find the dependencies (or use the Maven plugin to automatically). According to your example command line, you are only passing in the classpath of the application classes, not its dependencies.
