Sep 17 00:00:00 2001 From: gusthoff Date: Fri, 19 Jun 2026 19:32:15 +0200 Subject: [PATCH 11/32] Python: add edge-case unit tests for chop.py MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds test_chop.py in the package test directory covering manual_chop and cheapo_gnatchop edge cases not present in the existing frontend/sphinx/tests/test_chop.py. manual_chop additions: .ads and .adb Ada extensions, empty input, input with no !filename lines at all, garbage before the first valid file marker, single filename with no content, fake extensions not matched. cheapo_gnatchop additions: dotted package body names (Foo.Bar → foo-bar.adb), dotted procedure names, triple-dotted names, spec-only files (.ads), empty input, only-garbage input, garbage before the first declaration, body-before-spec ordering. Does not cover real_gnatchop (requires the Ada toolchain; already tested in sphinx/tests/test_chop.py).

Key fix in _make_block(): changed `buttons = buttons or ["no"]` to `buttons = ["no"] if buttons is None else buttons` so that passing `buttons=[]` explicitly is preserved (an empty list is falsy, causing the `or` form to silently substitute `["no"]`). Added compile_it and run_it parameters to _make_block() to allow tests to reach the BUTTONS check without triggering the compile path that requires a project file.

together they cap realistic coverage well below 90%. Add exclude_lines for "if __name__ == '__main__':" so the CLI entry-point blocks in check_code_block, check_projects, and extract_projects (approximately 80 lines total) are excluded from the measurement; those blocks are tested via the --help smoke tests rather than unit tests.

The existing tests always relied on the isolated_toolchain_path fixture, which pre-populated TOOLCHAIN_PATH before set_toolchain() was called, keeping the guard permanently false. The new test uses monkeypatch.delitem to remove "root" from TOOLCHAIN_PATH within the isolated fixture scope; set_toolchain() then triggers init_toolchain_info() at line 13, repopulating the dict from the real .ini file. The assertion checks that "root" is present again after the call.

Returns False (no error), covering the compile_it path in analyze_file() including prepare_project_block_dir() and to_json_file(). - test_analyze_file_run_button: same setup with a run_button attribute; covers the run_it branch (compile_it=True, run_it=True). - test_analyze_file_prove_button: SPARK Ada body with a prove_button attribute; write_project_file() uses spark_mode=True, covering the prove_it branch including the SPARK project-file path. All three tests require the Ada toolchain (gnatchop must be in PATH) and use the work_dir fixture so each test starts in a fresh temporary directory. Also removes line-number annotations from pre-existing section-header comments (line numbers are fragile and describe location rather than behaviour).
