eclipse.launcher returns NULL when running JUnit plug-in tests [message #985997]

Hi,

I am writing a plug-in that needs to retrieve the value of environment variable 'eclipse.launcher' set by Eclipse (so that I can create one more Eclipse). This works completely fine while I am testing the plug-in myself and eclipse.launcher is set to the correct value.

I have created a JUnit plug-in test so that I can automate some of the testing I need to do for my plug-in. However, in this plug-in tests, eclipse.launcher is not set (i.e., returns NULL), which completely crushes my remaining execution (and also testing).

Is there a configuration and/or workaround I can use for this?

Thank you, best regards,

I assume that JUnit plug-in tests don't use the launcher, which would be why the variable is not set in that context.
Possible workaround: explicitly pass this variable into your test launch?

For more qualified answers regarding JUnit plug-in tests you might want to ask in the PDE forum at http://www.eclipse.org/forums/index.php/f/14/

Hi Stephan, I tried using the environment variables (in run configurations) tab to do this, however it did not work. I also tried to set the environment variable 'eclipse.launcher' using a @BeforeClass method. However, as far as I can see, the product (the second Eclipse with my plug-in running on it), is created and run way earlier than @BeforeClass method is executed. Since my plug-in tries to read 'eclipse.launcher', it still reads null and cannot spawn the headless (third) Eclipse.

Is there any other way that I can pass the variable and make sure that it is set before the second (i.e., testing Eclipse with my plug-in) is created?

Thank you,

Launching JUnit plug-in tests is implemented in the PDE component, that's why I suggested that forum for more qualified answered.
