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+.
* Additional Unit Tests for XIRR and XNPV
See discussion in issue #3297. Excel result disagreed with PhpSpreadsheet, but it seems apparent that the error is Excel's. Although we have other test cases where Excel and PhpSpreadsheet disagree, those have so far been cases where Excel cannot give an answer because its algorithm does not converge, which is possible for any algorithm. In the issue in question, Excel seems to converge to a different answer; this is different than the other exceptions, and so deserves documentation with a formal test case. The discussion also mentions some cases where XNPV seems to give the wrong result in Excel, and those cases are added for XNPV.
* Scrutinizer
Whatever.
* Fix Unintential Deprecated Calls in Tests - FINANCIAL
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 Tests to Run in Spreadsheet Context
Found and fixed some problems with how MIRR handles errors.
* Extract remaining Financial function unit tests into separate test classes for each function
This makes it easier to manage unit tests if they are individual files rather than all in a single file
It also provides a stepping stone toward making it easier to test Excel functions when Excel errors no longer return a string, but an actual Excel exception that can be handled more cleanly
