How to pass the -D System properties while testing on Eclipse?

Question

I am developing on Eclipse on Windows and Code gets deployed on Unix. I am fetching the system property values using System.getProperty("key") ... How do I pass this in Eclipse so that I do not have to modify the code and it works on Eclipse for debugging?

Any suggestions?

Answer 1

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

where is this if you are trying to run an android application? – Horowitz

why do I have to use 'D' as prefix? – Roush

If you're as thick as me -- -D arguments go in the bottom box for VM arguments, not in the top box for your program's args. /sigh – Burnight

The top box is for the String[] args passed to the main method. – Whin

Is there any way to set this to happen by default, so you don't have to manually enter this repeatedly for many tests? – Bithynia

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

Answer 3

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.

If you meant "Program Arguments box" when you said "command-line args box" under Arguments tab - Does not Work! Has to be entered in "VM Arguments Box" as mentioned by Bombe above. – Altercation

Answer 4

This will work for junit. for TestNG use following command

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

Answer 5

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.
