在 Eclipse 上测试时如何传递-D System 属性？

Run -> Run configurations, select project, second tab: “Arguments”. Top box is for your program, bottom box is for VM arguments, e.g. -Dkey=value.

You can add command line arguments to your run configuration. Just edit the run configuration and add -Dmyprop=value (or whatever) to the VM Arguments Box.

You can use java System.properties, for using them from eclipse you could:

1. Add -Dlabel="label_value" in the VM arguments of the test Run Configuration like this:

2. Then run the test:

   import org.junit.Test;
   import static org.junit.Assert.assertEquals;
   
   
   public class Main {
   @Test
   public void test(){
   System.out.println(System.getProperty("label"));
   assertEquals("label_value", System.getProperty("label"));
   }
   }
   

3. Finally it should pass the test and output this in the console:

   label_value
   

Yes this is the way:

Right click on your program, select run -> run configuration then on vm argument

-Denv=EnvironmentName -Dcucumber.options="--tags @ifThereisAnyTag"

Then you can apply and close.

This will work for junit. for TestNG use following command

-ea -Dmykey="value" -Dmykey2="value2"
