Built-in Reporter Capture Harness

A small runnable harness that executes example scenarios using built-in console and JSON reporters while exercising output capture toggles and limits. Include two sample scenarios: one writes to stdout and the other writes to stderr so captured output is easy to verify.

Capabilities

Dual reporting by default

• Running the harness with default settings emits human-friendly console output and writes a JSON report to the provided path via built-in reporters from the dependency. @test

Captured stdout and stderr

• When capture is enabled, stdout/stderr produced by the sample scenarios is hidden from the console but available in captured output that accompanies the JSON report. @test

Passthrough mode

• When capture is disabled, stdout/stderr from the sample scenarios is shown directly in the console and is not stored in captured output. @test

Capture limit enforcement

• When a byte limit is provided for capture, the recorded stdout/stderr is truncated without exceeding that size and indicates truncation in the saved output. @test
