Hey,

I want to introduce click-tests to my swing-application and it seems AssertJ is the way to go ^^.

After testing and long investigations I still cant't get rid of one error and I'm very unsure it's a java-bug, a version-thing or related to the structure of the legacy-code.
I would be very happy if someone could point me in the right correction :):

When I run the testcase with in @onsetup:

ApplicationLauncher withArgs = application(MainClass.class).withArgs("args");
withArgs.start();

the test stops with

org.assertj.swing.dependency.fest_reflect.exception.ReflectionError: Unable to invoke method 'main' with arguments [['abc']]

Class-structure is:

DefaultWindow (gets created - then the error occurs) - extends
AbstractDefaultWindow extends 
AbstractWindow extends JFrame, 
implements IStatusMessageListener, ActionListener, ChangeListener, Observer

As it's a legacy-project - I inserted

assertj-core-3.17.2.jar
assertj-swing-junit-3.9.2.jar

by hand. Can this cause such a error?
I also tried to build my own all-containing-dependency-jar with

<dependencies>
<dependency>
  <groupId>org.assertj</groupId>
  <artifactId>assertj-swing-junit</artifactId>
  <version>3.9.2</version>
</dependency>
</dependencies>
  
  
<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>    
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

but it didn't help.

Would be very glad if someone could help me :)

Kind Regards

Hi @hansthesis2020

AssertJ Swing 3.17.0 is the way to go with AssertJ Core 3.17.x. But I think it doesn't change the behavior.

  • Which Java version are you using to run the tests?
  • Which Java version was the application compiled with?
  • What method signature does the main method in the MainClass have?

Best regards

THanks for the input - I double-checked java/compiler-versions, commented out some line of code and now I'm getting further :).
I will write again when I get solution and report it
