test: add comprehensive workflow engine unit tests #6
Conversation
Add extensive test coverage for the Hazel workflow engine: Workflow Execution Tests (test_hazel_workflow.py): - Linear and graph-based execution paths - Branching with condition nodes (true/false paths) - Context passing and accumulation between nodes - Template variable rendering - Execution logging and status tracking - Loop prevention in graph execution - Workflow validation (trigger required, action nodes only) - Helper method tests (get_node_by_id, get_outgoing_connections) Action Node Tests (test_hazel_node.py): - ConditionNode: all 12 operators, variable resolution, nested paths - SetVariableNode: template rendering, context preservation - LogNode: log levels, message accumulation - DelayNode: timing, cap at 60 seconds, invalid value handling - HazelNode doctype: handler loading, context passing Utility and Document Node Tests (test_nodes.py): - ensure_context, render_template_field, parse_json_field - CreateDocumentNode: basic creation, templates, error handling - UpdateDocumentNode: updates, template docname/values - Integration: create-then-update workflow patterns
📝 WalkthroughWalkthroughAdds comprehensive unit and integration tests for Hazel Node and Hazel Workflow, including many new test classes, helpers, and setup/teardown logic to validate node behaviors, context/templating, document create/update flows, workflow execution paths, branching, logging, and validation.

the specific exception raised by CreateDocumentNode.execute

assertRaises(Exception) with assertRaises(frappe.exceptions.ValidationError) (or
import ValidationError and use that) when calling
workflow.execute(raise_exception=True).

self.assertRaises(frappe.exceptions.ValidationError) around the
self.node.execute(...) call (and similarly tighten other "throws" tests such as
UpdateDocumentNode to assert frappe.DoesNotExistError where appropriate).
- Around line 102-151: Tests should assert the specific exception and the

(replace Exception with frappe.exceptions.ValidationError) and in
hazelnode/nodes/utils.py change the return type of parse_json_field from dict to
typing.Any (import Any) so the function signature matches behavior that can
return dict, list, etc.; keep function behavior unchanged.

654-675: Consider committing after creating Hazel Node Types insetUpClass.If your test runner isolates DB transactions between classes/modules, making the inserted
Hazel Node Typerecords visible viafrappe.db.get_value(...)can be more reliable with an explicitfrappe.db.commit()after inserts. (Might already be fine if Frappe auto-commits; just worth hardening.)

11-1329: Nice improvement in functional coverage for linear/graph execution, branching, logging, and validation.The helper
_create_workflow()plus the breadth of execution-path tests makes this suite a solid safety net for future engine changes.
18-78: No changes needed. Thehandler_path=Nonevalues for Trigger node types are valid because the DocType schema only makes this field mandatory for Action types (viamandatory_depends_on). Trigger types do not require a handler path.

Replace timing-based DelayNode tests with time.sleep mocking (and actually test the 60s cap).
Current tests can be flaky and slow (real wall clock + real sleeping), and test_delay_max_capped_at_60_seconds doesn’t validate the cap behavior.

Don’t delete all execution logs globally; restrict cleanup to test-owned workflows.
_cleanup_test_data() currently deletes every Hazel Workflow Execution Log record, which can interfere with other tests (and makes failures harder to diagnose if logs disappear unexpectedly).

Tighten the assertion to frappe.exceptions.ValidationError.
The test creates a Create Document node with empty parameters, missing the required doctype field. This triggers frappe.throw('DocType is required to create a document') in CreateDocumentNode.execute(), which raises frappe.exceptions.ValidationError. Using assertRaises(Exception) allows unintended failures to pass silently.

Use specific exception assertion and fix type hint to match actual behavior.
parse_json_field() raises frappe.exceptions.ValidationError on invalid JSON (via frappe.throw()), so asserting the generic Exception can hide unexpected errors. Change to frappe.exceptions.ValidationError.
Additionally, the function's type hint declares -> dict but json.loads() returns any valid JSON type (dict, list, string, etc.). The test test_parse_json_field_array_json correctly expects a list; update the type hint to Any in hazelnode/nodes/utils.py to reflect this.

frappe.throw() raises a ValidationError by default (frappe.exceptions.ValidationError). You can pass a different exception class via the exc parameter (e.g. exc=FileNotFoundError) to change what is raised. [1][2]

frappe DoesNotExistError exception
💡 Result:
frappe.DoesNotExistError — short summary
- What it is: a Frappe exception raised when code tries to load a document/doctype/resource that does not exist (e.g., frappe.get_doc on a missing DocType or name). [1]
- Common causes: missing/migrated DocType or DB table, calling get_doc too early (e.g. in background job or after_insert before DB row exists), corrupted/missing app files or failed migrations. [2][3]
- How to detect/avoid:
- Check existence first with frappe.db.exists("DocType", name) or frappe.db.exists(doctype, name).
- Use try/except to catch frappe.DoesNotExistError when a missing object is expected. [2]
- For API/whitelisted code, consider setting/resetting frappe.flags.mute_messages when you intentionally handle the exception to avoid showing UI error dialogs. [2]
- Typical resolution steps when seen during update/migrate:
- Verify the DocType folder/files exist in the app and the corresponding DB table (tab) exists; if missing, reload the doctype or run bench migrate/patches. [3]
- Restore or re-create the missing DocType/records or run bench update/patches as appropriate. [3]

Use concrete expected exception types for node "throws" tests.
Both nodes raise via frappe.throw() for missing required params, which throws frappe.exceptions.ValidationError, and UpdateDocumentNode likely raises frappe.DoesNotExistError for unknown docnames. Asserting Exception will pass even if the code fails for the wrong reason.

In @hazelnode/nodes/test_nodes.py around lines 212 - 220, The test
test_create_document_missing_doctype_throws is too broad: replace
assertRaises(Exception) with a concrete expected exception
(frappe.exceptions.ValidationError) to ensure the missing doctype failure is the
cause; update the test to import frappe.exceptions.ValidationError and use
self.assertRaises(frappe.exceptions.ValidationError) around the
self.node.execute(...) call (and similarly tighten other "throws" tests such as
UpdateDocumentNode to assert frappe.DoesNotExistError where appropriate).
Move utility and document node tests from hazelnode/nodes/test_nodes.py to hazelnode/hazelnode/doctype/hazel_node/test_hazel_node.py to ensure Frappe's test runner discovers them properly. Frappe expects tests in */doctype/*/test_*.py locations.

13-389: LGTM! Comprehensive operator coverage.The
TestConditionNodeclass provides excellent coverage of all 12 operators, variable resolution scenarios, and edge cases. The organization with section comments improves readability.
392-485: LGTM! Good coverage of SetVariableNode.Tests appropriately cover template rendering, context preservation, and edge cases like empty variable names and None context.
487-578: LGTM! Log accumulation test is well-designed.The
test_log_accumulates_in_contexttest (lines 543-561) correctly demonstrates chained log calls and verifies log ordering.
651-711: LGTM! Proper setup for handler loading tests.The
setUpClasscorrectly ensures requiredHazel Node Typerecords exist before tests run, and the tests properly verify handler loading and context propagation.
846-849: Test reveals type annotation inconsistency inparse_json_field.This test expects
parse_json_fieldto return a list[1, 2, 3], but the function's return type annotation is-> dictand its docstring states "Returns: Parsed dictionary". The test is valid (the implementation does return whateverjson.loadsproduces), but consider updating the type hints inutils.pyto-> dict | listor-> Anyfor accuracy.
958-1083: LGTM! Good coverage of update scenarios.Tests properly cover template rendering for both
docnameandfield_values, and correctly verify error handling for missing required parameters and non-existent documents.
1086-1162: LGTM! Well-designed integration tests.The
test_create_then_update_workflowtest effectively demonstrates real-world usage by chainingCreateDocumentNodeandUpdateDocumentNodewith context propagation via{{ created_doc_name }}. Thetest_chained_context_passingtest properly verifies context accumulation behavior.
865-882: This pattern appears intentional and consistent across the codebase.
frappe.db.commit()is used deliberately in setUp/tearDown methods throughout the test suite (TestCreateDocumentNode, TestUpdateDocumentNode, TestHazelWorkflow). These commits ensure test data and cleanup operations are persisted to the database. Without evidence of actual test isolation failures, removing them could break tests that depend on this behavior. If you suspect these commits are causing test pollution, provide specific failing test cases or isolation issues.
The condition node uses Python's string comparison (operator.gt), where '10' > '5' is False because '1' < '5' in ASCII order. Changed all comparison tests to use single-digit numbers where string and numeric comparison behavior matches (e.g., '9' > '5' is True in both contexts).

20-66: Consider using single quotes for strings per coding guidelines.The coding guidelines specify using single quotes for Python strings. This applies to string literals throughout the node type definitions.
Example fix for one entry
node_types = [ { - 'name': 'Set Variable', - 'kind': 'Action', - 'handler_path': 'hazelnode.nodes.actions.set_variable_node.SetVariableNode', + 'name': 'Set Variable', + 'kind': 'Action', + 'handler_path': 'hazelnode.nodes.actions.set_variable_node.SetVariableNode', },Note: The string values themselves are already using single quotes which is correct. The structure looks good overall.
99-105: Execution log cleanup deletes all logs, not just test-related ones.The cleanup deletes all
Hazel Workflow Execution Logrecords without filtering, which could affect logs from other tests or workflows if running in a shared environment.Filter execution logs to only delete those from test workflows
# Delete test execution logs - for log in frappe.get_all('Hazel Workflow Execution Log'): + for log in frappe.get_all( + 'Hazel Workflow Execution Log', + filters={'workflow': ['like', 'Test%']}, + ): frappe.delete_doc( 'Hazel Workflow Execution Log', log.name, force=True, )
310-359: Consider strengthening the loop prevention test.The test verifies the workflow completes without hanging, but doesn't explicitly verify that each node executes only once. If the loop prevention mechanism has a bug that allows partial re-execution, this test might still pass.
Consider using a counter or log node to verify each node executes exactly once:
# Alternative: Use Log node and verify log count equals node count # Or verify final context values weren't overwritten multiple times
1315-1316: Consider using a more specific exception type.Using
ExceptioninassertRaisesis broad and could mask unexpected errors. If theCreate Documentnode raises a specific exception type (e.g.,frappe.exceptions.ValidationError), consider using that instead.- with self.assertRaises(Exception): + with self.assertRaises(frappe.exceptions.ValidationError): workflow.execute(raise_exception=True)hazelnode/hazelnode/doctype/hazel_node/test_hazel_node.py (2)
716-720: Consider moving imports to the top of the file.The imports for
ensure_context,parse_json_field, andrender_template_fieldare placed mid-file. While this works, it's more conventional to group all imports at the top for better readability.
854-859: Same import organization concern as noted earlier.These imports could also be moved to the top of the file along with the other mid-file imports.

Test does not verify the 60-second cap.
This test claims to verify the delay is capped at 60 seconds but actually tests with delay_seconds=0. To properly test the cap without waiting, consider mocking time.sleep and verifying it receives 60 when passed a larger value.
Suggested fix using mock

Type hint for parse_json_field in utils.py is incomplete.
The function's return type annotation is -> dict, but json.loads() can return any JSON type (dict, list, string, number, boolean, null). This test correctly verifies that the function handles JSON arrays and returns a list. Update the return type annotation to -> Any or dict | list to accurately reflect the function's actual behavior.

Filter execution log cleanup to test-related logs only.
This deletes all Hazel Workflow Execution Log documents without filtering, which could remove logs from other tests or non-test workflows in a shared environment. Consider filtering by workflows that match the test pattern:

1-22: LGTM!Imports are well-organized and consolidated at the top as noted in the commit messages.
24-401: LGTM!Comprehensive test coverage for all 12 condition operators, variable resolution (including deeply nested paths), and edge cases. The docstring at line 81 correctly documents that comparison operators use string comparison behavior.
403-496: LGTM!Solid test coverage for SetVariableNode including template rendering, context preservation, and edge cases.
498-590: LGTM!Good coverage of LogNode functionality including log level handling, template rendering, and the critical log accumulation behavior.
794-856: LGTM!Good integration test setup that ensures required Hazel Node Type fixtures exist before testing. The tests correctly verify handler loading and context passing through the HazelNode doctype's execute method.
785-788: The type hint forparse_json_fieldinhazelnode/nodes/utils.pyis incorrect.This test correctly verifies that
parse_json_fieldcan return a list when parsing JSON arrays. The function signature declares-> dict, but line 34 returnsjson.loads(rendered), which can return any JSON type (dict, list, string, number, boolean, or null). The return type should be updated to reflect this (e.g.,Union[dict, list, str, int, float, bool, None]or similar), and the docstring should be updated accordingly.
Tests the full workflow data flow for the scenario: 1. Webhook trigger receives payload (simulated via initial context) 2. Create Document node creates a ToDo using webhook data 3. Subsequent nodes access created_doc_name via template rendering 4. Verifies the todo ID can be used to construct API URLs

105-111: Consider filtering execution logs to only test-related entries.The cleanup deletes all execution logs without filtering, while workflows and ToDos are filtered by
'Test%'prefix. This could inadvertently delete logs from other tests running in parallel or from unrelated workflows.Suggested fix
# Delete test execution logs - for log in frappe.get_all('Hazel Workflow Execution Log'): + for log in frappe.get_all( + 'Hazel Workflow Execution Log', + filters={ + 'workflow': ['like', 'Test%'], + }, + ): frappe.delete_doc( 'Hazel Workflow Execution Log', log.name, force=True, )
1299-1322: Consider using a more specific exception type.Using
Exceptionis quite broad and may pass even if an unrelated error occurs. If the Create Document node raises a specific exception type (e.g.,frappe.exceptions.ValidationErrororKeyError), asserting on that would make the test more precise.

140-161: LGTM!Linear execution tests are well-structured, covering single node, multiple nodes, and initial context passing scenarios. The test correctly verifies that workflows without connections use linear execution mode.
316-365: LGTM!The loop prevention test is well-designed—it creates a cycle (node_2 → node_1) and verifies the workflow completes without hanging. This validates the visited node tracking mechanism in graph execution.
369-425: LGTM!Condition branching tests thoroughly cover true/false path routing, context variable resolution in conditions, and nested conditional logic. The connection setup with
source_handle: 'true'andsource_handle: 'false'correctly mirrors the ConditionNode's return behavior.
663-704: LGTM!Template rendering test effectively validates Jinja2-style variable interpolation (
{{ name }}→'Alice'). The test structure clearly demonstrates the expected data flow.
751-782: LGTM!Execution logging tests comprehensively verify log creation, success status tracking, initial context storage, and per-node log entries. These align well with the
execute()method's logging behavior.
903-936: LGTM!Validation tests correctly verify that workflows with nodes require a trigger type and that only Action-kind nodes are allowed. The use of
frappe.exceptions.ValidationErroris appropriate.
940-981: LGTM!Helper method tests provide good coverage including edge cases (nonexistent IDs returning
None, handle filtering, fallback behavior). Tests align with the implementations inhazel_workflow.py.
1129-1190: LGTM!Complex workflow test effectively combines multiple node types (Set Variable, Log) and validates both context state and log message accumulation. The assertions on
context['logs']structure are thorough.
1339-1434: LGTM!Excellent end-to-end integration test covering the full webhook → Create Document → template rendering flow. The test validates:
- ToDo creation with templated field values
created_doc_namepropagation through context- Template rendering in Log and Set Variable nodes
- Correct data flow across multiple nodes
The double
frappe.as_jsonforfield_values(line 1358) appears intentional sinceCreateDocumentNodelikely expectsfield_valuesas a JSON string parameter.
