* This file contains tests for operations on flash chip.
*
* Two flash chip test variants are used:
*
* 1) Mock chip state backed by `g_chip_state`.
* Example of test: erase_chip_test_success.
*
* 2) Mock chip operations backed by `dummyflasher` emulation.
* Dummyflasher controls chip state and emulates read/write/unlock/erase.
* `g_chip_state` is NOT used for this type of tests.
* Example of test: erase_chip_with_dummyflasher_test_success.
