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+.
* Fix Unintential Deprecated Calls in Tests - LOGICAL
I think it's best to install these before PR #3166. There are no changes to source code, only to doc-blocks and to test members which continue to inadvertently use calls to deprecated functions.
* Change Unit Tests to Run in Spreadsheet Context
They had been run as direct calls, which is not how most users would use them. Making this change exposed some minor coding errors - SWITCH needs to flatten its arguments, and IFERROR and IFNA were not handling a null testValue in the same manner as Excel.
* Let's start with some appeasements to phpstan, just to reduce the baseline
* Appeasements to phpstan, taking the number of reported errors down to just 61
* Merge branch 'master' of C:\Projects\PHPOffice\PHPSpreadsheet\develop with conflicts.
* New statistical tests
* Sniffs
* Additional statistical function unit tests
* Additional statistical function unit tests
* Fix case-sensitivity
* Fix HARMEAN code logic
* Unit tests refactored into individual files for all logical functions
Implemented IFNA()
* Fix silly typo
* NOT needs ...args to allow for test when no argument passed
* Codestyle
* Use instance asserts
