PHPUnit fails silenlty

Question

when i run $ phpunit alone it fails silently and this is what i tried to know what the problem is with no luck:

$ phpunit
$ echo $?
=> 255

$ php -i | grep error

display_errors => STDOUT => STDOUT
display_startup_errors => On => On
error_append_string => no value => no value
error_log => /usr/local/var/log/php_error.log => /usr/local/var/log/php_error.log
error_prepend_string => no value => no value
error_reporting => 32767 => 32767
html_errors => Off => Off
ignore_repeated_errors => Off => Off
log_errors => On => On
log_errors_max_len => 1024 => 1024
track_errors => On => On
xmlrpc_error_number => 0 => 0
xmlrpc_errors => Off => Off
xdebug.force_display_errors => On => On

checking for syntax errors, return everything is ok:

for f in $(find tests/)
> do php -l $f
> done
...

as a temporary workaround, i run all tests as follow

find . -name "*_Test.php" -type f -exec phpunit {} \;

php_error.log has no log entry, and to make sure nothing is writting on the file:

$ truncate -s0 /usr/local/var/log/php_error.log
$ phpunit
$ tail /usr/local/var/log/php_error.log

and i do have write access to do log file: -rw-rw-r-- 1 adam adam 0 Sep 2 11:49 /usr/local/var/log/php_error.log

and to be safe:

$ php -r "error_log('am i logged?');"
$ tail /usr/local/var/log/php_error.log
[02-Sep-2016 13:16:37 Europe/Paris] am i logged?

when i do phpunit tests/* only files on the root directory tests are running, phpunit does not go recursively

this is phpunit.xml

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         bootstrap="bootstrap.php"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false">
    <testsuites>
        <testsuite name="Application Test Suite">
            <directory suffix=".php">./tests</directory>
        </testsuite>
    </testsuites>
</phpunit>

and this is the content of the bootstrap.php file

<?php

require_once __DIR__ . '/vendor/autoload.php';
require_once dirname(dirname(__FILE__)) . '/wp-load.php';
require_once ABSPATH . 'wp-admin/includes/admin.php';


use Dotenv\Dotenv;


do_action('admin_init');

(new Dotenv(__DIR__))
    ->load();

i know there is no errors, which is weird, echo $? return 255 after running phpunit, because when i run

psysh bootstrap.php it works with no errors

i'll appreciate any help, even if it's hacki, i just want to run test coverage, and produce a report. thank you

UPDATE

as a temporary workarround i run all tests using this command: find . -name "*_Test.php" -type f -exec phpunit {} \;

test single file

What i notice so far is as long as the target directory does not contain any subdirectories, phpunit process all test files within that directory, otherwise it fails silently.

Answer 1

Your directory suffix is probably wrong.

Here: you are trying to execute every php file as a test:

<testsuites>
    <testsuite name="Application Test Suite">
        <directory suffix=".php">./tests</directory>
    </testsuite>
</testsuites>

But here you're restricting it to "*_Test.php"

find . -name "*_Test.php" -type f -exec phpunit {} \;

Try:

<testsuites>
    <testsuite name="Application Test Suite">
        <directory suffix="Test.php">./tests</directory>
    </testsuite>
</testsuites>
