     - Helps debug test failures without manually capturing output
     - Enabled by default; use `--no-output-on-failure` or `BASHUNIT_SHOW_OUTPUT_ON_FAILURE=false` to disable
     - New CLI options: `--show-output`, `--no-output-on-failure`
+- Add `--no-progress` flag to suppress real-time progress display (Issue #503)
+    - Hides per-test output, file headers, hook messages, and spinner during execution
+    - Shows only the final test summary
+    - Useful for CI/CD pipelines or log-restricted environments
+    - Can also be set via `BASHUNIT_NO_PROGRESS=true` environment variable

+### No Progress
+
+> `bashunit test --no-progress`
+
+Suppress real-time progress display during test execution, showing only the final summary.
+
+When enabled, bashunit hides:
+- Per-test output (pass/fail messages or dots)
+- File headers ("Running tests/...")
+- Hook completion messages
+- Spinner during parallel execution
+
+The final summary with test counts and results is still displayed.
+
+This is useful for:
+- CI/CD pipelines where streaming output causes issues
+- Log-restricted environments
+- Reducing output noise when only the final result matters
