While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
And quite a bit more manual changes. The idea is that typing of our
tests can be a bit more loose, so we assume PHPDoc is mostly correct. If
that happens to be wrong, it should be caught by the tests themselves.
Successor to PR #3523. There are 494 single-line changes (`public function provider` to `public static function provider`) in this PR. None of these were made manually; they were all created with the following script (adapted from
https://stackoverflow.com/questions/25909820/how-to-recursively-iterate-through-files-in-php):
```php
$dir = 'C:/git/unit10prep2/tests/PhpSpreadsheetTests';
$it = new RecursiveDirectoryIterator($dir);
// Loop through files
foreach(new RecursiveIteratorIterator($it) as $file) {
if ($file->getExtension() === 'php') {
$contents = file_get_contents($file);
$new = preg_replace('/public function (\\w*)([Pp])rovider/', 'public static function $1$2rovider', $contents);
if ($new !== $contents) {
echo "changing $file\n";
file_put_contents($file, $new);
}
}
}
```
After this PR, there will be one more, with a small number of test changes, and enabling PhpUnit 10 for Php 8.1+.
* Coerce Bool to Int for Unary Operation on Arrays
Fix#3389. It seems some functionality was left behind when JAMA was eliminated (PR #3260). In particular, it is apparently a known trick to use double negation on boolean values as arguments to functions like SUMPRODUCT.
* Fix 3396
Treat booleans in arrays as int for mathematical operators as well.
* Edge Case
When array operand was neither numeric nor boolean, PhpSpreadsheet had always been evaluating the operand as #NUM!. It will now propagate an error string like #DIV/0!, and treat non-error strings as #VALUE!, consistent with Excel.
Scrutinizer had previously suggested annotations for 3 LookupRef tests, but it no longer accepts its own annotation for those cases. This PR cleans them up. ColumnsTest and RowsTest are extremely straightforward.
IndexTest is a bit more complicated, but only because, unlike the other two, it had no test which executed in the context of a spreadsheet. And, when I added those, I discovered a couple of bugs. INDEX always requires at least 2 parameters (row# is always required), but its entry in the function table specified 1-4 parameters, now changed to 2-4. And, omitting col# is not handled the same way as specifying 0 for col#, though the code had treated them identically. (The same would have been true for row# but, because it is now required, ...)
* Start work on array-enabling the Lookup and Reference functions
Requires a new method (`evaluateArrayArgumentsSubsetFrom()`) in the `ArrayEnabled` Trait to handle functions where the arguments that need special array handling are trailing rather than leading arguments
* Extract LookupRef\INDEX() into index() method of LookupRef\Matrix class
Additional tests
* Bugfix for returning a column using INDEX()
* Some improvements to ROW() and COLUMN()
* Simplify some of the INDEX() logic, eliminating redundant code
