* tests: assert pathname and flags when calling open()Daniel Campello2022-04-061-0/+15
| | | | | | | | | | | | | | | | | | | With this change the wrappers for mock and friends are able to take an optional io_mock_fallback_open_state struct to assert expected pathnames and flags whenever an open operation is called.

* tests: Add wrap for libusb_init and use it in dediprog testAnastasia Klimchuk2021-10-181-0/+1
| | | | | | | | | | | | | | | | | | | | Missing wrap for libusb_init has been discovered while working on the test for raiden_debug_spi. Both dediprog (existing test) and raiden_debug_spi (new test, see later in this chain) are using libusb_init, so it definitely needs to be wrapped and added to io_mock. Why tests worked before, without the wrap: my understanding is that real libusb_init was called for dediprog test? Given that tests definitely should not call any real libusb functions, wrap is needed.

* tests: Move current_io to io_mock.c be visible across testsAnastasia Klimchuk2021-10-181-0/+2
| | | | | | | | | | | | | | | | | | tests.c is growing and needs to be split, specifically all libusb wraps need to be extracted into their own file. See later in the chain a lot more wraps are added for libusb functions. To be able to split it, current_io needs to be moved one level up, to be visible across tests. This allows having multiple files with wraps, and all the wraps can use current_io.

* tests: Add tests to read from chipAnastasia Klimchuk2021-10-011-0/+3
| | | | | | | | | | | | | | | | | | | | Two tests cover the code which performs do_read operation. First one works with fake chip and dummy programmer. Fake chip has all operations defined, and a buffer to emulate chip memory. Second one uses the chip which is closer to the real one, because read/write/unlock/erase operations are real. The tests takes the advantage of dummyflasher's capability of emulating a W25Q128.V chip.

* tests: Mock file i/o for linux_mtd and linux_spi testsAnastasia Klimchuk2021-08-301-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds an init-shutdown test for linux_mtd. Since linux_mtd is using file i/o operations, those are added to the framework and mocked. Another driver linux_spi which is also using file i/o, got an upgrade in this patch, and it is now reading max buffer size from sysfs (using mocked file i/o). A good side-effect is that linux_mtd is the first test for opaque masters, which is great to have in preparation for a change like CB:56103 but for opaque masters.
