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?

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? – user678392 Sep 28 '13 at 23:17
why do I have to use 'D' as prefix? – Manticore Oct 06 '14 at 10:25

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 – ruffin Nov 20 '14 at 18:52

The top box is for the `String[] args` passed to the `main` method. – jaco0646 Sep 23 '15 at 21:42

Is there any way to set this to happen by default, so you don't have to manually enter this repeatedly for many tests? – Stewart Mar 28 '16 at 22:24

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

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

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"));
    }
}

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

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. – Devang Kamdar May 14 '09 at 09:42

This will work for junit. for TestNG use following command

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

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.
