You cannot do this I'm afraid - in general you cannot set a variable in one
recipe that will be read by another. See:
https://wiki.yoctoproject.org/wiki/Technical_FAQ#How_do_I_change_how_my_recipe_is_built_depending_on_what_image_I.27m_building.3F
The only real way to do what you're looking for is to have two different
recipes (where the name is actually different, not just the version). e.g. you
could have myapp_git.bb and myapp-test_git.bb. You could use a common
inc file and "require" that from both .bb files in order to keep the common
parts in one place. Then you can specify the corresponding package name
in each image recipe.
Cheers,
Paul
