Also enforce more rigorous Excel Function implementation by testing the underlying implementation, call via the Calc Engine, and execution from in a worksheet.
Separate out unhappy path (exception) checks into a separate test, so that a single test isn't made overcomplex checking for every potentiality.
Scrutinizer may dislike variadics, for variable number of arguments of mixed type; but tough. It's 100% valid PHP, accepted by phpstan, and makes life a lot easier.
Initial work here covers all the database and datetime unit tests for Excel function implementations.
Test both the function implementation (directly), and when the function is called in a formula from a spreadsheet
Replace error strings in expected result for providers with the value returned from the ExcelErrors class
* Fix Unintential Deprecated Calls in Tests - DATABASE
I think it's best to install these before PR #3166. There are no changes to source code, only to test members which continue to inadvertently use calls to deprecated functions.
* Fix deprecation Blocks
Deprecated->deprecated, adjust see and comments
* Fix Deliberate Deprecated Tests
Add annotations.
* Change Unit Tests to Run in Spreadsheet Context
... rather than as direct calls. The major difference is that specifying an invalid column should result in an Excel error, not null. Minor code changes were needed, including to Statistical/Conditional which sometimes calls Database.
* Correct Some DocBlocks
Null is no longer a possible output for most of these functions.
* 2 Overlooked Tests
Change to run in spreadsheet context.
* T Function Should Return Null-String, not Null
Fix it.
* Refactor the Excel Database functions; and rewrite the query building to fix a bug with complex multi-criteria queries that involve both AND and OR conditions
* Fix handling for empty cells and NULL values in searches
* Expand unit tests; and add TODOs for dates, percentages, and wildcard text comparisons
