test_executor.c

Comprehensive test suite for the executor module.

Tests: exec_utils, command_search, redirections, heredoc, logical operators, pipeline, subshell, block, background, simple command execution (builtins + externals).

Uses functional stubs from test_stubs.c for dependencies.

static void test_builtin_temp_assignments(void)

A VAR=val builtin assignment is visible to the builtin and restored afterwards.

Drives HOME=/tmp cd: cd with no arguments changes to $HOME, so a successful chdir to /tmp proves the builtin saw the temporary HOME, and HOME reverting to its prior value proves exec_builtin restored it. The process cwd is saved and restored since cd runs in-process.

static void test_pipeline_with_heredoc(void)

static void test_sequence_mixed(void)

static int run_shell(const char *input, int which_fd, char *out, size_t outsz)

Run ./42sh, feed input on stdin, capture one fd, return exit code.

which_fd selects the captured stream (1 = stdout, 2 = stderr); the other stream is sent to /dev/null.

Parameters:

• input – Command text written to the shell’s stdin.

• which_fd – 1 to capture stdout, 2 to capture stderr.

• out – Buffer receiving the captured output (NUL-terminated).

• outsz – Size of out.

Returns:

The shell’s exit code, or -1 on failure.

static void test_b1_exit_stops_sequence(void)

B1: a ; list must stop at exit; nothing after it runs.

static void test_b1_exit_stops_or_chain(void)

B1: an || branch must not run once exit has stopped the shell.

static void test_b2_assignment_reaches_pipeline(void)

B2: FOO=val env | cat must show FOO in the piped command’s env.

static void test_b4_not_executable_is_126(void)

B4: a non-executable file invoked by path exits 126 (permission).

static void test_b4_missing_path_is_127(void)

B4: a genuinely missing path still exits 127 (not found).
