Types

struct TestCtx

Accumulates test pass/fail counts; each failing assertion prints a diagnostic to stderr.

Fields

current: String

failed: i32

passed: i32

Methods

fn assert_eq_i32(self: &mut TestCtx, actual: i32, expected: i32) -> void

Asserts actual == expected, widening to i64 and delegating to assert_eq_i64.

fn assert_eq_i64(self: &mut TestCtx, actual: i64, expected: i64) -> void

Asserts actual == expected; the failure diagnostic includes both values.

fn assert_eq_str(self: &mut TestCtx, actual: &[u8], expected: &[u8]) -> void

Asserts actual and expected are byte-for-byte equal.

fn assert_false(self: &mut TestCtx, cond: bool) -> void

Asserts cond is false; a failure is recorded and execution continues (no abort).

fn assert_true(self: &mut TestCtx, cond: bool) -> void

Asserts cond is true; a failure is recorded and execution continues (no abort).

fn begin(self: &mut TestCtx, name: &[u8]) -> void

Starts a named test case; name is included in failure messages until the next begin.

fn fail(self: &mut TestCtx, reason: &[u8]) -> void

Records an unconditional failure with reason in the diagnostic.

fn new() -> TestCtx

Creates a TestCtx with zero counts and no current test name.

fn summary(self: &TestCtx) -> i32

Prints a pass/fail summary to stderr; returns exit code 0 on success, 1 on any failure.
