add IsTypeOf() of enumerations regression tests

[jens-maus]

Regression tests for OpenCCU/OpenCCU#2950, fixed by OpenCCU/ReGaHss#8.

Background

IsTypeOf() reported an enumeration to be of the type of its elements, e.g. dom.GetObject(ID_DEVICES).IsTypeOf(OT_DEVICE) returned true, as the enumeration types share the type bits of their elements (OT_DEVICES = otDevice | otEnum | otObject contains OT_DEVICE = otDevice | otObject). The internal type checks then accessed the enumeration as an element, e.g. a delayed State() on ID_DATAPOINTS crashed ReGaHss (SIGSEGV) once executed by the scheduler.

Tests (test/13-fixed-bugs.js, IsTypeOf() of enumerations tests)

• the root enumerations ID_DEVICES, ID_CHANNELS, ID_DATAPOINTS, ID_USERS, ID_RULES and ID_INTERFACES are not of the type of their elements, but of their own enumeration type, OT_ENUM and OT_OBJECT (false true true true),
• their elements (gateway channel, its device, ID_PRESENT, the first user and interface) are still of their type and not of the enumeration types (true false false true),
• a delayed State(1, 300) on ID_DATAPOINTS and ID_CHANNELS returns true, the scheduler logs execution of scheduler only allowed on DP, CHANNEL or PROGRAM and ReGaHss keeps running.

The tests require ReGaHss R1.00.0388.0259 (requireRegaVersion()), so they are skipped with older ReGaHss versions.

Local verification

Run natively with REGA_BIN (x86_64, npx mocha test/13-fixed-bugs.js, npx xo clean for this file), with the version requirement temporarily lowered:

• ReGaHss built from OpenCCU/ReGaHss main including Bump yargs-parser from 20.2.1 to 20.2.3 #8: the three new tests pass,
• ReGaHss without Bump yargs-parser from 20.2.1 to 20.2.3 #8 (R1.00.0388.0258): the enumeration test fails (true true true true) and ReGaHss crashes (SIGSEGV) in the delayed State() test.

(The DST test fails locally in both runs, as the local environment runs in UTC.)

Summary by CodeRabbit

• Tests
  • Added coverage for type checks on enumerations and their elements.
  • Added checks for delayed state calls on enumerations, including scheduler rejection handling and continued system responsiveness.

Adds version-gated tests for enumeration type checks and delayed State() calls on datapoint and channel enumerations.

Changes

Enumeration regression tests

Layer / File(s)	Summary
Enumeration type checks test/13-fixed-bugs.js	Adds assertions for the types of root enumerations and their elements.
Delayed State calls test/13-fixed-bugs.js	Checks that delayed calls on datapoint and channel enumerations return true, produce the expected scheduler rejection, and leave ReGa responsive.

Merge Risk: 🔵 Low · up to e3b29

This change only adds regression tests. The delayed State test may not catch a crash from the datapoint callback, which weakens its regression protection but does not affect runtime behavior.

- Line 922: Update the test flow around the `waitForRega` matcher to also await
the rejection from the scheduled `ID_DATAPOINTS` callback before the final
`rega.exec()` liveness check. Match the datapoint rejection’s expected ID and
message for the target version, while retaining the channel rejection check.
