Test Suite

Embody has 110+ test suites (2,500+ tests) under dev/embody/unit_tests/ covering externalization, MCP tools, TDN format, the Envoy server/bridge/jobs, install/upgrade paths, and infrastructure. Destructive and agent tiers are segregated behind their own entry points.

Running Tests

From TouchDesigner:

op.unit_tests.RunTests()                          # All tests, one per frame
op.unit_tests.RunTests(suite_name='test_path_utils')  # Specific suite
op.unit_tests.RunTests(suite_name='test_path_utils', test_name='test_normalizePath_backslashes_converted')
op.unit_tests.RunTestsSync()                      # Synchronous (blocks TD)
results = op.unit_tests.GetResults()              # Get results dict

Via MCP -- use the run_tests tool, NOT RunTestsSync inside execute_python:

run_tests(background=True)           # all suites -- RECOMMENDED for full runs
get_job_status(job_id='job_...')     # poll; the finished record carries the summary
run_tests(suite_name='test_path_utils')   # small targeted runs may stay synchronous

For a FULL run always pass background=True: it returns a job id immediately and results park restart-proof in .embody/jobs/. The synchronous mode holds the HTTP call open for the whole run, and the Envoy watchdog suites restart the very server it waits on -- the call is severed ("Server force-restarted / shutting down during test run") even though the run finishes. (Pre-job-layer fallback, still valid: poll execute_python(code="result = op.unit_tests.GetResults()") until the totals stop moving.)

RunTestsSync() inside execute_python runs the whole suite INSIDE that dispatch's undo block: the undo-guard tests fail (a block is already open) and the entire run becomes one giant Ctrl+Z step.

Writing New Tests

Create a test file in dev/embody/unit_tests/:

"""Test suite: description of what this tests."""

class TestMyFeature(EmbodyTestCase):
    def test_something(self):
        """Test description."""
        op = self.sandbox.create(baseCOMP, 'test_op')
        result = self.embody_ext.someMethod(op)
        self.assertEqual(result, expected_value)
        self.assertTrue(op.valid)
        self.assertIn('foo', result)

    def setUp(self):
        pass

    def tearDown(self):
        super().tearDown()  # Cleans up sandbox

Key objects: self.sandbox (temp baseCOMP), self.embody (op.Embody), self.embody_ext (op.Embody.ext.Embody), self.runner (TestRunnerExt). All TD globals available.

Test Coverage

Count suites with ls dev/embody/unit_tests/test_*.py -- the hand-maintained breakdown that used to sit here drifted 4x stale and was removed. Suite docstrings state their scope.

After Running Tests

Always read log files at dev/logs/ — the ring buffer only holds 200 entries. Grep for ERROR and WARNING.
