Custom Frontend Extra Path Environment

To define extra path environment variables that can be accessed globally by all tests in a frontend create a file in the root of the snap called extra_path_environment. All paths in the file are relative to the root of your snap and will be correctly made absolute before passing them to your tests.

Example:

# This library we are installing in a weird location
LD_LIBRARY_PATH += path to library
# Additionally we need to define this very important path
SOME_PATH += /very/important/location

Note

This mechanism is designed to define PATH variables specifically to address issues in packaging. Do not use this for general purpose environment variable setting.

Warning

All variables paths point to the root of your snap at runtime, regardless if you prefix them with a / or not.
