TestMetaData

Documentation: Test Metadata Wrappers Module

---

1. Purpose

This module provides thin managed wrappers around low-level ISO.* data entities (LabratoryDetails, CustomerDetails, TestEngineerDetails) to support database import operations within the DataPRO system. It exposes simplified, namespaced access to metadata entities used during test configuration and reporting, including CRUD-like operations (e.g., DeleteAll) and instance management (e.g., singleton list for engineers). The module exists to decouple the import pipeline from direct dependencies on the ISO layer, enabling testability and future flexibility in metadata handling.

---

2. Public Interface

LabratoryDetails

• public string Name { get; set; }
  Gets or sets the laboratory name by delegating to the underlying _lab.Name field.

LabratoryDetailsList

• public static void DeleteAll()
  Invokes ISO.LabratoryDetails.DeleteLabratoryDetails() to remove all laboratory detail records from persistent storage.

CustomerDetails

• public string Name { get; set; }
  Gets or sets the customer name by delegating to _customerDetails.Name.

CustomerDetailsList

• public static void DeleteAll()
  Invokes ISO.CustomerDetails.DeleteCustomerDetails() to delete all customer detail records.

TestEngineerDetails

• public TestEngineerDetails()
  Default constructor initializes _testEngineerDetails to a new ISO.TestEngineerDetails instance with Name set to "(none)".
• public TestEngineerDetails(ISO.TestEngineerDetails testEngineerDetails)
  Copy constructor: initializes _testEngineerDetails by constructing a new ISO.TestEngineerDetails from the provided instance.
• public string Name { get; set; }
  Gets or sets the engineer’s name via _testEngineerDetails.Name.

TestEngineerDetailsList

• public static TestEngineerDetailsList TestEngineerList { get; }
  Static singleton accessor for the single TestEngineerDetailsList instance.
• public void ReloadAll()
  Thread-safely repopulates the internal _testEngineers dictionary by calling GetAllTestEngineers() and caching entries keyed by Name.
• public static void DeleteAll()
  Clears the in-memory _testEngineers dictionary and invokes ISO.TestEngineerDetails.DeleteAllTestEngineerDetails() to purge persisted records.
• private TestEngineerDetails[] GetAllTestEngineers()
  Returns an array of TestEngineerDetails objects: first a sentinel "(none)" entry (via default constructor), then one entry per record returned by ISO.TestEngineerDetails.GetAllTestEngineerDetails().

Note

: GetAllTestEngineers() is private, but used internally by ReloadAll() and implicitly by the PopulateEngineers() method.

---

3. Invariants

• Name is the only mutable property exposed via the public interface for all three detail classes (LabratoryDetails, CustomerDetails, TestEngineerDetails).
• TestEngineerDetailsList is a singleton — only one instance exists (_testEngineerList), accessed via TestEngineerList.
• Thread safety for ReloadAll() is enforced via lock (_testEngineerLock) around PopulateEngineers().
• "(none)" sentinel entry is always the first element in the list returned by GetAllTestEngineers().
• Duplicate names are prevented in _testEngineers dictionary: PopulateEngineers() only adds an entry if !_testEngineers.ContainsKey(t.Name).
• _testEngineers is nullified on DeleteAll(), forcing a full reload on next access.

---

4. Dependencies

Dependencies of this module:

• ISO.LabratoryDetails (type with static methods DeleteLabratoryDetails())
• ISO.CustomerDetails (type with static method DeleteCustomerDetails())
• ISO.TestEngineerDetails (type with static methods GetAllTestEngineerDetails(), DeleteAllTestEngineerDetails(), and constructors)
• System.Collections.Generic.Dictionary<string, TestEngineerDetails> (used in TestEngineerDetailsList)

Dependencies on this module:

• Not explicitly stated in source, but given the naming and structure, this module is likely consumed by:
  • DatabaseImport pipeline components (e.g., importers that populate or validate test metadata).
  • UI or service layers that require test metadata (e.g., selecting engineer or lab for a test run).

---

5. Gotchas

• Typo in class names: All classes use Labratory (misspelled) instead of Laboratory. This is preserved from the underlying ISO layer and must be maintained for compatibility.
• TestEngineerDetails is not thread-safe for concurrent mutation — while ReloadAll() is synchronized, direct access to _testEngineerDetails.Name (via Name property) is not guarded.
• _testEngineerDetails field in TestEngineerDetails is not readonly, unlike the others — implying potential reassignment (though not observed in current code).
• GetAllTestEngineers() silently ignores duplicate names — only the first occurrence is retained in _testEngineers.
• No validation on Name values — empty strings or duplicates are allowed at the wrapper level (though duplicates are deduped in TestEngineerDetailsList).
• CustomerDetailsList and LabratoryDetailsList have no instance members beyond DeleteAll() — they are effectively static namespaces.
• TestEngineerDetailsList caches in-memory state — changes made directly to ISO.* entities outside this module may not be reflected until ReloadAll() is called.

None identified beyond those above.
