wordpress-develop unit testing couldn't fetch mysqli


wordpress-develop unit testing couldn't fetch mysqli



I've seen a lot of mysqli errors on stack overflow, but none seem to relate to wordpress-develop



I set up the test folder, bootstrap.php.


if ( function_exists( 'xdebug_disable' ) ) {
xdebug_disable();
}
if ( false !== getenv( 'WP_DEVELOP_DIR' ) ) {
require getenv( 'WP_DEVELOP_DIR' ) . 'testsphpunitincludesbootstrap.php';
}
if ( false !== getenv( 'WP_PLUGIN_DIR' ) ) {
define( 'WP_PLUGIN_DIR', getenv( 'WP_PLUGIN_DIR' ) );
}



phpunit.xml


<phpunit bootstrap="tests/bootstrap.php">
<testsuites>
<testsuite>
<directory prefix="test-" suffix=".php">./tests/</directory>
</testsuite>
</testsuites>
</phpunit>



config


define( 'DB_NAME', 'bitnami_wordpress_testing' );
define( 'DB_USER', 'root' );
define( 'DB_PASSWORD', '' );
define( 'DB_HOST', 'localhost' );
define( 'DB_CHARSET', 'utf8' );
define( 'DB_COLLATE', '' );



When I run a simple test


class test extends WP_UnitTestCase {
public function test_foo_is_foo() {
$this->assertTrue( 'foo' === 'foo' );
}
}



I get the result along with a slew of warnings.

I tested a couple basic methods and don't seem to be getting info from the database either. Not sure if there is any significance in the fact that the warnings are repeated. Does anyone with wordpress-develop experience know where this issue is likely coming from. Or perhaps anyone know of a better method/preferred tutorial for getting unit testing with wordpress up and running?

I had the same issue but the warnings disappeared when I updated phpunit to version 6.5 (for testing with WordPress 4.9.4) whilst I was using version 5.0.* before.

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...

Opening a url is failing in Swift

Opening a url is failing in Swift breakpointing inside the callback and logging success shows false.
