ERROR TestSuiteGenerator - Full stack: java.lang.IllegalArgumentException: null

[pablovalle]

Context

Hi, I am trying to generate Junit test cases to test an application done in Java, using Springboot and Hybernate. I am using maven to run evosuite because i want to integrate it in my Continuous Integration system (using Jenkins).

Steps to Reproduce

I have build the pom.xml as it appears here: [https://www.evosuite.org/documentation/maven-plugin/]()

EvoSuite Arguments

I am triyng the following command: mvn compile evosuite:generate

Current Result

The result i get is the following one:

[INFO] === CTG run results === [INFO] Removed test suites: 0 [INFO] New test suites: 0 [INFO] Missing classes: [INFO] com.mufit.pum.web.UserRegistrationController [INFO] com.mufit.pum.config.SecurityConfig [INFO] com.mufit.pum.PumGameApplication [INFO] com.mufit.pum.config.LocaleConfig [INFO] com.mufit.pum.util.PasswordGenerator [INFO] com.mufit.pum.web.dto.UserRegistrationDto [INFO] com.mufit.pum.service.UserServiceImplementation [INFO] com.mufit.pum.web.MainController [INFO] com.mufit.pum.service.UserSecurityService [INFO] WARN: failed to generate tests for 9 classes out of 9 [INFO] Stopping spawn process manager [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 01:53 min [INFO] Finished at: 2020-12-16T14:06:42+01:00 [INFO] ------------------------------------------------------------------------

The log file says this:

[MASTER] 14:05:30.559 [pool-2-thread-1] ERROR TestSuiteGenerator - Problem for com.mufit.pum.config.SecurityConfig. Full stack: java.lang.IllegalArgumentException: null at org.evosuite.shaded.org.objectweb.asm.ClassReader.(ClassReader.java:160) at org.evosuite.shaded.org.objectweb.asm.ClassReader.(ClassReader.java:143) at org.evosuite.shaded.org.objectweb.asm.ClassReader.(ClassReader.java:418) at org.evosuite.setup.InheritanceTreeGenerator.analyzeClassStream(InheritanceTreeGenerator.java:238) at org.evosuite.setup.InheritanceTreeGenerator.createFromClassPath(InheritanceTreeGenerator.java:101) at org.evosuite.setup.DependencyAnalysis.initInheritanceTree(DependencyAnalysis.java:77) at org.evosuite.setup.DependencyAnalysis.analyzeClass(DependencyAnalysis.java:131) at org.evosuite.TestSuiteGenerator.initializeTargetClass(TestSuiteGenerator.java:110) at org.evosuite.TestSuiteGenerator.generateTestSuite(TestSuiteGenerator.java:130) at org.evosuite.rmi.service.ClientNodeImpl$1.run(ClientNodeImpl.java:145) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748)

Expected result

The expected result will be the Junit Test-cases build but i have no one.

Additional info

I am using this: mvn --version Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f) Maven home: C:\apache-maven-3.6.3\bin..

Many Thanks! Pablo.

Hi @pablovalle,

Any chance you can try the latest version of EvoSuite? As the latest version has not been uploaded to the mvnrepository yet, you should first execute the following steps:

git clone https://github.com/EvoSuite/evosuite.git
cd evosuite
mvn install -DskipTests=true

and only then modify the following line in your project's pom.xml file from

<evosuiteVersion>1.0.6</evosuiteVersion>

to

<evosuiteVersion>1.1.1-SNAPSHOT</evosuiteVersion>

You can then re-execute the mvn compile evosuite:generate command.

-- Best, Jose

Hi @jose,

First of all thank you for your attention.

After having followed your indications I have been able to execute the mvn compile evosuit:generate command, and the proccess starts well but it gets blocked when the first job starts. It says that it will finish in 10 minutes (555 seconds) but it doesn't finish. I have left it and it says that the job has not finished in time... Ihave tried more than once getting the same output.

Here you have what it says:

Hi @jose,

Trying to understand where does evosuite block, we have found the following problem:

"Could not run phased build action using Gradle distribution 'https://services.gradle.org/distributions/gradle-6.3-bin.zip'.\r\nCould not create an instance of type org.gradle.invocation.DefaultGradle.\r\nCould not configure services using GradleScopeCompileServices.configure().\r\nclass jdk.internal.loader.ClassLoaders$PlatformClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$PlatformClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')",

This problem is in evosuite folder so we don't know why could happen this.

Many thanks, Pablo.

I'm afraid I can't understand that message. Isn't your project a maven-based project?

Any chance you can try to generate tests for a single class using EvoSuite's command line rather than EvoSuite's mvn plugin? I.e., in your project's directory run the following commands:

# Download project's deps
mvn dependency:go-offline -Dmaven.repo.local=deps

# Run EvoSuite on `com.mufit.pum.web.UserRegistrationController`
java -jar ___path_to_evosuite_repo_dir__\master\target\evosuite-master-1.1.1-SNAPSHOT.jar -class com.mufit.pum.web.UserRegistrationController -projectCP target\classes:deps

[pablovalle]

Okey, i will do it one by one this way it works.

Thank you!

[qfzjava]

bro, I got the same problem with u, I have saw the answer up there. but i don't know how to run the command:

Download project's deps

mvn dependency:go-offline -Dmaven.repo.local=deps

Run EvoSuite on com.mufit.pum.web.UserRegistrationController

java -jar _path_to_evosuite_repo_dir\master\target\evosuite-master-1.1.1-SNAPSHOT.jar -class com.mufit.pum.web.UserRegistrationController -projectCP target\classes:deps

can u teach me how to run the command... thank u!!!!!

[qfzjava]

this is my error:

[pablovalle]

Hi,

Just run the command: java -jar "path to evosuite dir repo"\master\target\evosuite-master-1.1.1-SNAPSHOT.jar -class "class you want to generate tests" -projectCP target\classes:deps
