 # AssertThrows
 
+Handle exceptions inside a test without a stop! Works with PHPUnit and Codeception.
+
 [![Build Status](https://travis-ci.org/Codeception/AssertThrows.svg?branch=master)](https://travis-ci.org/Codeception/AssertThrows)
 
-Handle exceptions inside a test without a stop!
+## Installation
 
----
+```
+composer require codeception/assert-throws --dev
+```
 
-Assertions for exceptions. Works with PHPUnit and Codeception.
+Include `AssertThrows` trait it to a TestCase:
+
+```php
+<?php
+
+class MyTest extends PHPUnit\Framework\TestCase
+{
+    use Codeception\AssertThrows;
+
+    //...
+} 
+```
 
 ## Usage
 
 Catch exception thrown inside a code block.
 
 ```php
 <?php
+
 $this->assertThrows(NotFoundException::class, function() {
-	$this->userController->show(999);
+	$this->userController->show(99);
 });
 
 // alternatively
-$this->assertThrows(new NotFoundException, function() {
-	$this->userController->show(999);
+$this->assertThrows(new NotFoundException(), function() {
+	$this->userController->show(99);
 });
-?>
-```
 
-You can optionally test the exception message:
-
-```php
-<?php
-$this->assertThrowsWithMessage(NotFoundException::class, 'my error message', function() {
-	throw new NotFoundException('my error message');
+// you can also assert that an exception is not throw
+$this->assertDoesNotThrow(NotFoundException::class, function() {
+    $this->userController->show(99);
 });
-?>
 ```
