The unit tests in \tool_uploaduser\cli_test fail if a plugin has created a custom checkbox profile field with default 0. (This is slightly similar to MDL-77611 but a completely different issue.)

This appears to be caused by \profile_field_base::edit_field_set_default() which incorrectly checks if default data is available by using empty(), which misses defaults of 0 and the empty string.

To reproduce, unzip the attached file local_fortest.zip into the local directory of Moodle, initialise phpunit and run tool_uploaduser_testsuite. (I hope timhunt doesn't mind me nicking his code from MDL-77611 )

The tests will fail with errors like this:

moodle_exception : error/CLI script finished with error code 1
