PHPUnit xslt

###PHPUnit logfile XLST template

This fileset provides an easy way to view the PHPUnit XML (JUnit) logfiles in a human readable manner using a web browser.

Use this either in combination with the accompanying html file or add the following tag straight after the xml opening tag of the logfile: <?xml-stylesheet type="text/xsl" href="phpunit.xslt"?>

The thresholds used for the colour-coding and whether or not to show detail for successfull tests can be changed by adjusting the variables at the top of the xslt file.

Notes on input validation for WP Core

What is input validation ?

Checking for a variable/ array index:

  • Does it exist ?
  • Is it of the right type ?
  • Is the value usable for our purposes ?

Problem definition:

  • Lack of input validation throughout most of Core.
  • ... which is especially problematic in the context of filter hooks / callbacks.

Draft: Upgrade guide to PHP_CodeSniffer 3.5.0 for sniff developers

Upgrade guide to PHP_CodeSniffer 3.5.0 for sniff developers

PHP_CodeSniffer 3.5.0 contains a lot of changes under the hood. For the most part these are non-breaking.

If you maintain an external standard, you have three options:

  • Maintain compatibility with older PHP_CodeSniffer versions [1]. In that case, there is probably nothing you need to do. Just make sure you check the BC-breaks section below just in case. All the "old" utility methods and properties will still work. They will however be removed in PHPCS 4.0.
  • Maintain compatibility with older PHP_CodeSniffer versions [2].

View phpcs3.5-changelog.txt
- Squiz.Formatting.OperatorBracket.SpacingAfterMinus has been renamed to Squiz.Formatting.OperatorBracket.SpacingAfterSign
-- If you are referencing the old error code in a ruleset XML file, please use the new code instead
-- If you wish to maintain backwards compatibility, you can provide rules for both the old and new codes
- `Conditions::getCondition()` accepts both a single token type or an array of token types for the `$type` parameter, which has been renamed to `$types` to convey this. The parameter is also now optional.
Additionally, the new version of the method has an optional boolean `$reverse` parameter which allows to indicate whether to get the _first_ condition of a certain type or the _last_.
- `ObjectDeclarations::getClassProperties()` now has improved handling of class declaration code interlaced with comments and/or annotations
- `ObjectDeclarations::findExtendedClassName() and `ObjectDeclarations::findExtendedInterfaceNames()` will now return the class/interface names witho
