This article mainly introduces the testing methods and examples of PHP scripts. Interested friends can refer to it. I hope it will be helpful to everyone.
1. Commonly used test examples
We often encounter this situation: some legacy codes that have not been tested are rewritten and tested, and even these codes are still Written using object orientation. To test code like this, my advice is to break the code into chunks so it's easier to test.
However, these legacy codes are not so easy to refactor. For example, you cannot rewrite the code before testing. This is to avoid affecting the original program, and of course it is not easy to perform unit testing.
In PHP programs, part of the code is usually written in several index.php and script.php files. These .php files are stored in several different folders. If their entry points are not found, they cannot be accessed directly by the web server.
Test copy
To test a PHP script, we need to simulate an HTTP request and check whether the returned response is equal to the expected value. What needs to be noted here is to simulate a request and define response and request. Not only are the contents different, but their headers are also different.
Also, if we want to test a transaction script that manipulates data, we want to make sure that we don't let it connect to the real database or the rest of the application.
In reality, usually no one will directly rewrite the original PHP script for testing. Because I'm afraid of making the code unrecoverable. I recommend using a copy of the PHP script so we can perform some minor surgery on the PHP code.
How to make minimal modifications to the code: delete include and require statements (if they are not used), and modify the way internal functions are called, for example: write header() as $object->header() .
Finally, let’s test this transaction script. After testing, we can extract them from the duplicate script and put them into a new script file.
Specific steps
1. Simulate an HTTP request and redefine the variables $_GET and $_POST, and also modify the header of $_SERVER.
2. Get the request response. The body of the response can be captured through ob_start() and ob_get_clean(). It can collect every buffer (buffer content) output with echo() or with the
Note: Output buffering supports multiple levels of nesting in PHP, so in most cases, it will be captured, even if the script is using the ob_* call itself.
3. The test script should contain the internal methods of the transaction script, so all methods within the scope of this script can be called. For example:
1. The variables required by the script can be defined as local variables and encapsulated, such as $connection as a database connection.
2. It is not the original built-in function of PHP. It should be called with an object. For example: header() is written as $this->header().
Specific code
This is the transaction script object we want to test. Specific to the script, we also need to encapsulate:
<?php class ForumPosting { private $headers = array(); public function handleRequest($postRequest) { $_POST = $postRequest; $connection = $this->getAConnection(); ob_start(); include 'forum/post_new_copy.php'; $content = ob_get_clean(); return array( 'content' => $content, 'headers' => $this->headers ); } private function header($headerLine) { $this->headers[] = $headerLine; } ... }
This is us Test code:
public function testANewPostIsCreated() { $action = new ForumPosting(); $response = $action->handleRequest(array( 'id_thread' => 42, 'text' => 'Hello, world', ... )); $this->assertEquals('...', $response['content']); $this->assertContains('Content-type: text/html', $response['headers']); }
The test copy is only temporary! It allows us to write tests that don't change. Finally, we will refactor the PHP scripts that have passed the test to eliminate redundant code.
When our test is completed, the contents of handleRequest() can be replaced with real logic code. If you want to write many such test scripts, you can write a general test object to meet your testing needs.
2. Unit testing toolkit for PHP developers
In the PHP field, there are three main unit testing tools: PHPUNIT, PHPUNIT2 and SimpleTest. Among them, PHPUNIT is very simple in function and not perfect; PHPUNIT2 is a unit testing tool specially written for PHP5, which is in line with Junit in structure and function; and SimpleTest is a very practical testing tool, among which webTest supports The testing of web program interface is the most recommended testing tool by Easy. In this article, we choose SimpleTest for introduction.
Related knowledge: PHPUNIT2 is also a very good tool, especially the architecture. There are many things worth highlighting. I hope I will have the opportunity to share it with you in a dedicated article in the future.
SimpleTest: That’s it. Simple
Installing SimpleTest is very simple. Download a source code package from sf.net, then unzip it to the web directory and you can use it. I won’t go into details here.
Let’s look at an example first: write a test to check whether a website can be accessed.
First we introduce the files to be used:
Code list:
require_once("../simpletest/unit_tester.php"); require_once("../simpletest/web_tester.php"); require_once("../simpletest/reporter.php");
Then we create a test class:
Code list:
class TestOfSite extends WebTestCase { function TestOfSite() { $this->WebTestCase("测试"); } function testSite() { $this->get("http://howgo.net/prettyface/display.php"); $this->assertTitle(".: facebook :."); } }
First we extend the webTestCase class so that we can automatically obtain the ability to test the web. Then in the constructor we directly use the base class and just pass the title to it. Then we should write the test method. The test methods all start with 'test' to identify which methods in the class need to be called when we run the test.
And $this-> get will get the content of the web page, we specify its title as ".: facebook:.", and then all we have to do is instantiate the object of this class and run it.
代码列表:
$test = &new TestOfSite(); $test->run(new HtmlReporter());
下边是运行结果:
如果测试出错则会出现下边的界面:
到这里一个简单的测试就算完成了。
实战演习 – 一个Login测试
下面我们进入实战,在这个基础上完成一个login的测试。这次我们先贴出完整的代码:
代码列表:
require_once("../simpletest/unit_tester.php"); require_once("../simpletest/web_tester.php"); require_once("../simpletest/reporter.php"); class TestOfLogin extends WebTestCase { function TestOfLogin() { $this->WebTestCase("Login测试"); } function testLoginOk() { // 取得页面 $this->get("http://howgo.net/prettyface/login.php"); // 添加测试表项 $this->setField("name","Easy"); $this->setField("pass","******"); // 提交 $this->clickSubmit("提交"); // 察看提交后返回页面是否正确 $this->assertWantedPattern("/成功登录/"); // 点击页面链接 $this->clickLink("点击这里进入管理页面"); // 察看指定页面标题和关键内容 $this->assertTitle("ADMINCP"); $this->assertWantedPattern("/请选择要进行的任务/"); // 退出登陆 $this->clickLink("退出管理"); $this->clickLink } }

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
