| ## FIDL definitions used in unit testing |
| |
| The FIDL workflow is tested at multiple levels. `fidl_coded_types.cc` contains hand-written |
| coding tables for the message types, and their corresponding C structure definitions are found in |
| `fidl_structs.h`. Most tests in encoding/decoding exercise these manual coding table definitions. |
| Though not one-to-one generated, `messages.test.fidl` contains a general outline of the FIDL |
| definitions under test, for reference. |
| |
| On the other hand, certain FIDL constructs are used in the higher layers, but are not supported |
| by the C bindings right now, e.g. tables. `fidlc` is able to generate the coding tables for FIDL |
| tables, but cannot generate their binding APIs. In order to unit test the table code paths, we will |
| generate and check in their LLCPP bindings `extra_messages.h` from `extra_messages.test.fidl`. |
