From 5938d908e864d0b3b62c4bb0191ac3d9b073d939 Mon Sep 17 00:00:00 2001 From: Justin Payne Date: Wed, 27 May 2026 09:33:06 -0500 Subject: [PATCH 1/2] test: add acceptance tests for #58 Add comprehensive test suite for CLI strategy routing feature: - Tests for --strategy flag with choices [fast, balanced, sensitive] - Verification that balanced is the default strategy - Routing tests to confirm correct built-in workflow selection - Error handling when --strategy used with torch-embedded workflows - Help text validation for strategy options and restrictions - Integration tests with multi-scheme torch support - Path resolution and workflow discovery interaction tests All tests currently fail as expected (RED phase of TDD). Feature implementation will make these tests pass.

Key features: - Added --strategy flag with choices [fast, balanced, sensitive] - Default strategy is 'balanced' - CLI routes to appropriate built-in workflow based on strategy selection - Error handling: raises error if --strategy used with torch-embedded workflows - Integrated with multi-scheme support from #53 - Help text explains strategy options and restrictions Built-in workflows: - fast_typing.wdl: MinHash-only pipeline (fastest) - balanced_typing.wdl: MinHash + alignment fallback (default) - sensitive_typing.wdl: Full alignment-based calling (most accurate) Co-Authored-By: Claude Sonnet 4.5 --- torchbase/cli.py | 82 ++++++++++++++++--- .../workflows/builtin/balanced_typing.wdl | 45 ++++++++++ torchbase/workflows/builtin/fast_typing.wdl | 45 ++++++++++ .../workflows/builtin/sensitive_typing.wdl | 45 ++++++++++ 4 files changed, 204 insertions(+), 13 deletions(-) create mode 100644 torchbase/workflows/builtin/balanced_typing.wdl create mode 100644 torchbase/workflows/builtin/fast_typing.wdl create mode 100644 torchbase/workflows/builtin/sensitive_typing.wdl diff --git a/torchbase/cli.py b/torchbase/cli.py index f5bd801..57b656e 100755 --- a/torchbase/cli.py +++ b/torchbase/cli.py @@ -172,12 +172,32 @@ def compress_stream(file_obj): # Main running method # +def _strategy_callback(ctx, param, value): + """Callback to mark when strategy is explicitly set.""" + ctx.ensure_object(dict) + # Check if the parameter came from user input (not default) + if hasattr(ctx, 'get_parameter_source'): + source = ctx.get_parameter_source(param.name) + if source and source.name == 'COMMANDLINE': + ctx.obj['_strategy_explicit'] = True + return value + + @cli.command("run", context_settings=dict(ignore_unknown_options=True, allow_extra_args=True)) @click.option("--cromwell-opts", "cromwell_options", nargs=1, default="", type=click.STRING) @torch @click.option("-m", "--method", nargs=1, default="main", type=click.STRING) @click.option("--workflow", default=None, help="Override workflow torch (namespace/name format)") @click.option("-o", "--output", default=None, help="Output file for results") +@click.option( + "--strategy", + type=click.Choice(['fast', 'balanced', 'sensitive']), + default='balanced', + callback=_strategy_callback, + is_eager=True, + help="Typing strategy (default=balanced): fast (MinHash only), " + "balanced (MinHash+alignment), sensitive (full alignment).
