Codeception module for validation of messages logged by PSR3 loggers.

Developed by Byteout Software.

Compatibility

Installation

1. Install and configure Codeception

2. Install module using composer

   composer require "byteout/psr-logger-codeception-module" --dev

3. Enable the module in your suite {NAME}.suite.yml:

   modules:
       enabled:
           - Byteout\Codeception\Module\PsrLogger

Examples

1. Simple usage

   <?php
       
   $logger = $I->grabLogger();
   $logger->notice('This is logger example.');
   
   $I->seeLoggerHasNotice('This is logger example.');

2. Track logs from other services

   <?php
   
   use Psr\Log\LoggerInterface;
   
   class HelloWorld
   {
       private $logger;
   
       public function __construct(LoggerInterface $logger)
       {
           $this->logger = $logger;
       }
   
       public function sayHello($name)
       {
           $this->logger->info("Hello $name");
       }
   }
   
   $logger = $I->grabLogger();
   $service = new HelloWorld($logger);
   
   $service->sayHello('John');
   
   $I->seeLoggerHasInfo('Hello John');

3. Simulate logs

   <?php
   
   $I->haveWarning('Something bad happened', ['problem' => 'This is more info.']);
   
   $I->dontSeeLoggerHasAnyError();
   $I->seeLoggerHasAnyWarning();
   $I->seeLoggerHasWarningThatContains('bad');

Actions

Get logger instance

public function grabLogger(): \Psr\Log\LoggerInterface;

Log message

public function haveEmergency(string $message, array $context = []);
public function haveAlert(string $message, array $context = []);
public function haveCritical(string $message, array $context = []);
public function haveError(string $message, array $context = []);
public function haveWarning(string $message, array $context = []);
public function haveNotice(string $message, array $context = []);
public function haveInfo(string $message, array $context = []);
public function haveDebug(string $message, array $context = []);

Example:

$I->haveEmergency('This is emergency');
$I->haveEmergency('This is emergency with context', ['error' => 'This is context array']);

Check if specific message was logged

When context is null only message is matched, and context is ignored. When context is array it will be fully matched, along with the message.

public function seeLoggerHasEmergency(string $message, array $context = null);
public function seeLoggerHasAlert(string $message, array $context = null);
public function seeLoggerHasCritical(string $message, array $context = null);
public function seeLoggerHasError(string $message, array $context = null);
public function seeLoggerHasWarning(string $message, array $context = null);
public function seeLoggerHasNotice(string $message, array $context = null);
public function seeLoggerHasInfo(string $message, array $context = null);
public function seeLoggerHasDebug(string $message, array $context = null);

Example

// matches all 'This is emergency' emergency messages, despite the context
$I->seeLoggerHasEmergency('This is emergency');

// matches only message with the given context
$I->seeLoggerHasEmergency('This is emergency with context', ['error' => 'This is context array']);

Check if specific message was not logged

When context is null only message is matched, and context is ignored. When context is array it will be fully matched, along with the message.

public function dontSeeLoggerHasEmergency(string $message, array $context = null);
public function dontSeeLoggerHasAlert(string $message, array $context = null);
public function dontSeeLoggerHasCritical(string $message, array $context = null);
public function dontSeeLoggerHasError(string $message, array $context = null);
public function dontSeeLoggerHasWarning(string $message, array $context = null);
public function dontSeeLoggerHasNotice(string $message, array $context = null);
public function dontSeeLoggerHasInfo(string $message, array $context = null);
public function dontSeeLoggerHasDebug(string $message, array $context = null);

Example

// fails if any 'This is emergency' emergency message was logged, despite the context
$I->dontSeeLoggerHasEmergency('This is emergency');

// fails only when a message with the given content and context was logged
$I->dontSeeLoggerHasEmergency('This is emergency with context', ['error' => 'This is context array']);

Check if any message was logged

public function seeLoggerHasAnyEmergency();
public function seeLoggerHasAnyAlert();
public function seeLoggerHasAnyCritical();
public function seeLoggerHasAnyError();
public function seeLoggerHasAnyWarning();
public function seeLoggerHasAnyNotice();
public function seeLoggerHasAnyInfo();
public function seeLoggerHasAnyDebug();

Check if no message was logged

public function dontSeeLoggerHasAnyEmergency();
public function dontSeeLoggerHasAnyAlert();
public function dontSeeLoggerHasAnyCritical();
public function dontSeeLoggerHasAnyError();
public function dontSeeLoggerHasAnyWarning();
public function dontSeeLoggerHasAnyNotice();
public function dontSeeLoggerHasAnyInfo();
public function dontSeeLoggerHasAnyDebug();

Check if message containing substring was logged

public function seeLoggerHasEmergencyThatContains(string $message);
public function seeLoggerHasAlertThatContains(string $message);
public function seeLoggerHasCriticalThatContains(string $message);
public function seeLoggerHasErrorThatContains(string $message);
public function seeLoggerHasWarningThatContains(string $message);
public function seeLoggerHasNoticeThatContains(string $message);
public function seeLoggerHasInfoThatContains(string $message);
public function seeLoggerHasDebugThatContains(string $message);

Example:

// matches all emergency messages containing 'emergency' substring
$I->seeLoggerHasEmergencyThatContains('emergency');

Check if message containing substring was not logged

public function dontSeeLoggerHasEmergencyThatContains(string $message);
public function dontSeeLoggerHasAlertThatContains(string $message);
public function dontSeeLoggerHasCriticalThatContains(string $message);
public function dontSeeLoggerHasErrorThatContains(string $message);
public function dontSeeLoggerHasWarningThatContains(string $message);
public function dontSeeLoggerHasNoticeThatContains(string $message);
public function dontSeeLoggerHasInfoThatContains(string $message);
public function dontSeeLoggerHasDebugThatContains(string $message);

Example:

// fails is any emergency message containing 'emergency' substring was logged
$I->dontSeeLoggerHasEmergencyThatContains('emergency');

Check if message matching regular expression was logged

public function seeLoggerHasEmergencyThatMatchesRegex(string $regex);
public function seeLoggerHasAlertThatMatchesRegex(string $regex);
public function seeLoggerHasCriticalThatMatchesRegex(string $regex);
public function seeLoggerHasErrorThatMatchesRegex(string $regex);
public function seeLoggerHasWarningThatMatchesRegex(string $regex);
public function seeLoggerHasNoticeThatMatchesRegex(string $regex);
public function seeLoggerHasInfoThatMatchesRegex(string $regex);
public function seeLoggerHasDebugThatMatchesRegex(string $regex);

Example:

// matches all emergency messages passing regex '/emergency/i'
$I->seeLoggerHasEmergencyThatMatchesRegex('/emergency/i');

Check if message matching regular expression was not logged

public function dontSeeLoggerHasEmergencyThatMatchesRegex(string $regex);
public function dontSeeLoggerHasAlertThatMatchesRegex(string $regex);
public function dontSeeLoggerHasCriticalThatMatchesRegex(string $regex);
public function dontSeeLoggerHasErrorThatMatchesRegex(string $regex);
public function dontSeeLoggerHasWarningThatMatchesRegex(string $regex);
public function dontSeeLoggerHasNoticeThatMatchesRegex(string $regex);
public function dontSeeLoggerHasInfoThatMatchesRegex(string $regex);
public function dontSeeLoggerHasDebugThatMatchesRegex(string $regex);

Example:

// fails is any emergency message passing regex '/emergency/i was logged
$I->dontSeeLoggerHasEmergencyThatMatchesRegex('emergency');

Check if message was logged using callback

public function seeLoggerHasEmergencyThatPasses(callable $matcher);
public function seeLoggerHasAlertThatPasses(callable $matcher);
public function seeLoggerHasCriticalThatPasses(callable $matcher);
public function seeLoggerHasErrorThatPasses(callable $matcher);
public function seeLoggerHasWarningThatPasses(callable $matcher);
public function seeLoggerHasNoticeThatPasses(callable $matcher);
public function seeLoggerHasInfoThatPasses(callable $matcher);
public function seeLoggerHasDebugThatPasses(callable $matcher);

Example:

$I->seeLoggerHasEmergencyThatPasses(function ($record) {
    return $record['message'] === 'Test message' && $record['context']['error'] = 'Test error';
});

Check if message was not logged using callback

public function dontSeeLoggerHasEmergencyThatPasses(callable $matcher);
public function dontSeeLoggerHasAlertThatPasses(callable $matcher);
public function dontSeeLoggerHasCriticalThatPasses(callable $matcher);
public function dontSeeLoggerHasErrorThatPasses(callable $matcher);
public function dontSeeLoggerHasWarningThatPasses(callable $matcher);
public function dontSeeLoggerHasNoticeThatPasses(callable $matcher);
public function dontSeeLoggerHasInfoThatPasses(callable $matcher);
public function dontSeeLoggerHasDebugThatPasses(callable $matcher);

Example:

$I->dontSeeLoggerHasEmergencyThatPasses(function ($record) {
    return $record['message'] === 'Test message' && $record['context']['error'] = 'Test error';
});
