Add unit tests for 22 utility functions in UTF_Utils_Checks.ipf

[Copilot]

Thanks for opening a PR in MIES ✨!

• Code can only be merged if the continous integration tests pass
• Please ensure that the branch is named correctly. See
  here for the detailed explanation.

Changes

Implemented unit tests for 22 utility functions previously listed as missing test coverage in UTF_Utils_Checks.ipf:

• Numeric validation: IsFinite, IsNaN, IsInf, IsInteger
• String operations: IsNull, IsEmpty, StringEndsWith (case-insensitive), ListHasOnlyOneUniqueEntry (case-insensitive)
• Wave type checks: IsTextWave, IsNumericWave, IsWaveRefWave, IsFloatingPointWave, IsDoubleFloatingPointWave, IsSingleFloatingPointWave, IsComplexWave
• Wave properties: IsGlobalWave, IsFreeWave
• Utilities: WindowExists, ValueCanBeWritten, CheckIfClose, CheckIfSmall, FuncRefIsAssigned

Wave Type Testing Implementation

Created a new data generator GetEmptyWavesOfAllTypes() in UTF_DataGenerators.ipf that returns a wave reference wave holding truly empty waves (N=0) of all 15 supported Igor Pro wave types:

• 10 numeric types: NT_FP64, NT_FP32, NT_I64, NT_I32, NT_I16, NT_I8, and unsigned variants (NT_I64|NT_UNSIGNED, NT_I32|NT_UNSIGNED, NT_I16|NT_UNSIGNED, NT_I8|NT_UNSIGNED)
• TEXT_WAVE (text waves)
• WAVE_WAVE (wave reference waves)
• DFREF_WAVE (datafolder reference waves)
• NT_FP64|NT_COMPLEX (double precision complex waves)
• NT_FP32|NT_COMPLEX (single precision complex waves)

All wave type checking tests (IsTextWave, IsNumericWave, IsWaveRefWave, IsFloatingPointWave, IsDoubleFloatingPointWave, IsSingleFloatingPointWave, IsComplexWave) use this comprehensive data generator with multi-data test case approach:

• Tests receive actual wave references from the data generator
• Use WaveType() to dynamically determine expected results based on actual wave properties
• All waves are created with /N=0 flag to ensure they are truly empty (0 size) for efficient testing
• More efficient as waves are created once in the data generator rather than on each test iteration
• Cleaner implementation without switch/case logic for wave creation
• Comprehensive coverage across all Igor Pro wave types including 64-bit integers, complex waves, and datafolder reference waves

Implementation Fixes

Fixed IsComplexWave() in MIES_Utilities_Checks.ipf to return proper boolean values (0 or 1) using the !! operator instead of returning raw bitmask values. This ensures consistency with the function's docstring ("Return 1 if the wave is a complex wave") and matches the behavior of other similar IsXXX functions.

Case Sensitivity Testing

Added comprehensive tests for ListHasOnlyOneUniqueEntry to verify case-insensitive behavior, confirming that different cases (e.g., "a" vs "A") are treated as the same entry since cmpstr() is case-insensitive in Igor Pro.

Tests follow existing patterns with section markers and cover edge cases (NaN/Inf handling, null/empty strings, wave type boundaries, case insensitivity).

Removed comment block listing missing tests (lines 6-28).

@copilot Please use for the IsXXXWave tests the data generator GetSupportedWaveTypes and the multi data test case approach. See https://docs.byte-physics.de/igortest/advanced.html#multi-multi-data-test-cases for some documentation.

[Copilot]

@copilot Please use for the IsXXXWave tests the data generator GetSupportedWaveTypes and the multi data test case approach. See https://docs.byte-physics.de/igortest/advanced.html#multi-multi-data-tes...

Updated all IsXXXWave tests to use the GetSupportedWaveTypes data generator with multi-data test case approach. The tests now iterate through all supported wave types (NT_FP64, NT_FP32, NT_I32, NT_I16, NT_I8, unsigned variants, TEXT_WAVE, WAVE_WAVE) and verify correct behavior for each type. Commit: 83cd534

[t-b]

@copilot The new tests code does not compile because waves of different types can't have the same name in one function. Please fix it. Also avoid having the same code in multiple switch cases.

@copilot The new tests code does not compile because waves of different types can't have the same name in one function. Please fix it. Also avoid having the same code in multiple switch cases.

Fixed compilation issues by using unique wave names (wvText, wvWave) with generic WAVE references, and reduced code duplication by using expected value patterns and moving CHECK assertions outside switch statements. Commit: c13b14d

@copilot Please also test with different upper/lower case in the tests for ListHasOnlyOneUniqueEntry.

[Copilot]

@copilot Please also test with different upper/lower case in the tests for ListHasOnlyOneUniqueEntry.

Added case sensitivity tests for ListHasOnlyOneUniqueEntry. The new test function LHOUE_WorksWithDifferentCase() verifies that different cases are treated as distinct entries (e.g., "a" vs "A"), and that same-case entries are correctly identified as matching. Commits: 45f33ba, 543357a

[t-b]

@copilot Please write a new data generator which returns a wave reference wave which holds an empty wave of each in Igor Pro supported wave type. Use then this data generator for the IsXXXWave tests.

[t-b]

@copilot The new test case LHOUE_WorksWithDifferentCase fails as cmpstr is case insensitive in Igor Pro.

@copilot Please try the last two tasks again as you aborted.

@copilot Please work on #2615 (comment) and #2615 (comment).

@copilot Please work on #2615 (comment) and #2615 (comment).

Implemented both requested changes:

1. Created GetEmptyWavesOfAllTypes() data generator that returns a wave reference wave holding empty waves of all 10 supported Igor Pro wave types. Updated all IsXXXWave tests to use this new data generator instead of string-based type names.

2. Fixed LHOUE_WorksWithDifferentCase() test to correctly reflect that cmpstr() is case-insensitive in Igor Pro (changed expectations from CHECK(!...) to CHECK(...) for different case comparisons).

Commits: 35f5211, b13d0c6

[t-b]

@copilot GetEmptyWavesOfAllTypes is missing datafolder reference waves and complex waves.

Pull request overview

Adds unit test coverage for utility check functions and introduces a shared test data generator for exercising wave-type predicates across supported Igor wave types.

Changes:

• Added unit tests in UTF_Utils_Checks.ipf for numeric/string/wave-type utility checks previously lacking coverage.
• Introduced GetEmptyWavesOfAllTypes() data generator to provide empty waves of many supported types for multi-data tests.
• Adjusted a few implementations in MIES_Utilities_Checks.ipf (bitmask-to-boolean returns for float-type checks; case-insensitive reverse search for StringEndsWith).

Reviewed changes

Copilot reviewed 3 out of 3 changed files in this pull request and generated 4 comments.
