Vanessa Automation Scenario Policy

Trigger: creating or modifying a .feature file. When triggered, apply the vanessa-authoring skill (framework/skills/tool-usage/vanessa/vanessa-authoring/SKILL.md).

Purpose of Testing Layers (MUST - fundamental)

A scenario (Vanessa) test exists to verify client behavior through the UI, imitating user actions. The division of "what we test with which test" is canonical in tdd-policy (section "Purpose of layers"); here are only Vanessa specifics.

• Verified behavior goes ONLY through the UI. The scenario opens the form and imitates the user with real UI steps (window opened, in the field named ... I enter, I click the ... button, I see the element, element ... is available). It is FORBIDDEN to replace the user action path with a server call (ПроверитьЗаполнение(), ЗаписатьОбъект(), direct call of a common module) - such a "scenario" is a unit test in Vanessa clothing and misses form-layer defects.
• Server-side BSL in Vanessa is allowed ONLY for data preparation/cleanup (fixtures, setup, teardown - see the two-session split below), NOT as a replacement for the checked user scenario. Boundary: code "prepares the stage" - server-side is allowed; code "checks behavior" - only through the UI.
• Why this rule exists. Bypassing the UI with a server call leaves all client logic (handlers, visibility/accessibility, navigation, form structure) without coverage - it is not checked by either such a "scenario" or a unit test, and the defect surfaces only for the user at runtime.

MUST

• The scenario is based on the task specification or an existing business case - no fictional cases.
• One scenario = one observable behavior.
• Before adding a new step, look for an existing one in the Vanessa library and the project scenarios.
• The first scenario for a new case is a short smoke test.
• The scenario is executed under a specific business user, not under admin/AgentAI - the only exception is if the function being checked is available exclusively to an administrator; the user is determined from the task description, and if it is missing, ask a human.
• Two-session split: infrastructure data preparation (creating objects, VAExtension steps, BSL fixtures) is done under the technical user (AgentAI); the business flow (behavior verification) is done under a specific business user. Switch via And I close TestClient + a new Given I connect TestClient. You cannot assign technical roles to the business user just to pass infrastructure steps.
• Task tag is mandatory. Every .feature file MUST contain the tag @task-<ID> (for example @task-103) at the Feature: level.
• Source comment. The file header (before the tags) MUST contain the comment: # Task: <ID> - <title>.
• Do not guess the logic - read the code (delegate to Explorer / code-navigation). A discrepancy between code and test is a discovered mismatch; record it as a result.
• Do not guess the interface - names and titles of elements, fields, buttons, tabs, availability and state of elements are taken from the real rendered interface, examined through Vanessa/TestClient or through the fallback via va-visual-check, not from guesses based on code or memory. Remember the difference between identifiers: the steps "contains strings" / "go to line" expect the title (Title), while "remember the field value" expects the name (name) - the exact value is learned by inspecting the form, not guessed. A discrepancy between the scenario and the real UI is a discovered mismatch; record it as a result.
• Manual fill-in before the scenario. A new document scenario is written AFTER filling the form manually through Vanessa/TestClient with verification of the form composition at every step (the field value affects visibility/requiredness of other fields); the key header fields and required tabular sections (>= several rows) are filled; the document hint/reference data have been studied; scrollbars hiding fields have been taken into account. If needed by the test meaning, the document is saved and posted, pop-up errors at the bottom of the screen are analyzed and the filling corrected. Fill-in scenarios are reusable "building blocks" (@exportscenarios), and one document can have several. Details - vanessa-authoring.
