(* * * * test.sml * * * *
|
||||||
|
*
|
||||||
|
* Small testing framework especially made for the Compiler course at Aarhus
|
||||||
|
* University.
|
||||||
|
*
|
||||||
|
* Should work on must systems where the compiler itself works. The VM should
|
||||||
|
* work, so should macOS and Arch Linux. TODO investigate.
|
||||||
|
*
|
||||||
|
* * Instructions * *
|
||||||
|
*
|
||||||
|
* 0. Copy this file into the compiler source directory.
|
||||||
|
* 1. Add any test files to the test directory.
|
||||||
|
* 2. Compile the compiler using `make sa ia` or similar.
|
||||||
|
* 3. Load the test framework with `use "test.sml";` in the interactive prompt.
|
||||||
|
* 4. Run tests with `Testing.perform_all_tests();` in the interactive prompt.
|
||||||
|
*
|
||||||
|
* Alternatively to `Testing.perform_all_tests: unit -> unit`, one can use
|
||||||
|
* `Testing.perform_tests: string -> unit`, which will only run tests with the
|
||||||
|
* given prefix.
|
||||||
|
*
|
||||||
|
* * Test types * *
|
||||||
|
*
|
||||||
|
* Must be located in the source directory of the relevant assignment. There
|
||||||
|
* must be a subdirectory with the name of `tests`, with the relevant files.
|
||||||
|
* The framework supports a large variety of test types:
|
||||||
|
*
|
||||||
|
* - *Basic Tiger tests*: Anything of the format `test_*.tig`. First line must
|
||||||
|
* indicate what the expected output is:
|
||||||
|
*
|
||||||
|
* * `/* output: x */` will indicate that the status code returned by the
|
||||||
|
* Tiger program must be `x`. These values must be in the range [0, 255]!
|
||||||
|
* * `/* print: |x| */` will indicate that the program must return errno 0,
|
||||||
|
* and must print the string `x`. `x` must not contain `|`, newlines, or
|
||||||
|
* certain other characters.
|
||||||
|
* * `/* nothing */` will indicate that the program must compile and run.
|
||||||
|
*
|
||||||
|
* - *Counterexample tests*: Sometimes you might want to test that something
|
||||||
|
* is caught by the compiler. Of the format `test_x_*.tig`. Useful for
|
||||||
|
* Lexing, Parsing and Semant stages.
|
||||||
|
*
|
||||||
|
* - *AST comparison tests*: When you want to ensure that precedence is parsed
|
||||||
|
* correctly, by comparing the AST of two distinct programs. Require twin
|
||||||
|
* files, one `test_*_implicit.tig`, another `test_*_explicit.tig`, obviously
|
||||||
|
* with the same `*`.
|
||||||
|
*
|
||||||
|
* - *LLVM tests*: For testing whether the LLVM-to-X86 backend works. Filenames
|
||||||
|
* must be of the format `test_llvm_*.sml`. These are SML files that are
|
||||||
|
* loaded by the test framework, and can perform whatever computations. Must
|
||||||
|
* use the `Testing.llvm_block_test: ll.block -> unit` function once and only
|
||||||
|
* once during the execution. This will register the block and compile it
|
||||||
|
* using the backend.
|
||||||
|
*
|
||||||
|
* The framework ignores any file not matching any of the above requirements.
|
||||||
|
* NOTE: All files must start with `test_`.
|
||||||
|
*
|
||||||
|
* Any slow tests can be renamed to `test_z_*`, and it'll be sorted last in the
|
||||||
|
* list.
|
||||||
|
*
|
||||||
|
* Please note that tests without any specified status codes are assumed to
|
||||||
|
* exit with a status of `0`.
|
||||||
|
*
|
||||||
|
* * Advanced usage * *
|
||||||
|
*
|
||||||
|
* TODO: Error numbers
|
||||||
|
*
|
||||||
|
* * Bugs * *
|
||||||
|
*
|
||||||
|
* Hard to escape SML once the testing has begun, as sigINT failes to trigger.
