How to use PHP scripts to implement automated testing on Linux servers

In the software development process, automated testing is a very important part, it can improve development efficiency, Ensure code quality and reduce the possibility of human error. This article will introduce how to use PHP scripts to implement automated testing on Linux servers and provide specific code examples.

1. Preparation
Before starting, we need to prepare the following work:

1. A server running a Linux operating system, you can choose Ubuntu, CentOS, etc.;
2. Install the PHP interpreter, you can use apt-get or yum to install;
3. Install the PHPUnit test framework, you can install it through Composer;
4. Write test cases and automated test scripts.

2. Write test cases
Before conducting automated testing, we need to write test cases. A test case is a set of test scripts used to verify whether the code logic is correct. Each test case only tests a specific function point and should be independent and non-interfering with each other.

Taking a simple website login function as an example, we can write the following test cases:

<?php
use PHPUnitFrameworkTestCase;
use GuzzleHttpClient;

class LoginTest extends TestCase
{
    protected $client;

    protected function setUp(): void
    {
        $this->client = new Client([
            'base_uri' => 'http://example.com',
            'timeout'  => 2.0,
        ]);
    }

    public function testLoginSuccess()
    {
        $response = $this->client->post('/login', [
            'form_params' => [
                'username' => 'admin',
                'password' => 'admin',
            ],
        ]);

        $this->assertEquals(200, $response->getStatusCode());
        $this->assertContains('Welcome', $response->getBody());
    }

    public function testLoginFailed()
    {
        $response = $this->client->post('/login', [
            'form_params' => [
                'username' => 'admin',
                'password' => 'wrong_password',
            ],
        ]);

        $this->assertEquals(401, $response->getStatusCode());
        $this->assertContains('Unable to login', $response->getBody());
    }
}

3. Write automated test scripts
After writing test cases, we need to write automated tests Script to execute these test cases and output the test results. The automated test script can be saved as a PHP file and executed through the command line.

<?php
require 'vendor/autoload.php';

$testSuite = new PHPUnitFrameworkTestSuite();
$testSuite->addTestSuite('LoginTest');

$testResult = new PHPUnitFrameworkTestResult();
$testResult->addListener(new PHPUnitTextUIResultPrinter());

$testSuite->run($testResult);

4. Execute the automated test script
In the Linux command line, use the following command to execute the automated test script:

php test.php

5. Execute the automated test script regularly
To achieve To automatically execute automated test scripts at scheduled times, you can use the scheduled task function of the Linux server. Use the crontab command to add a scheduled task, add the automated test script to the scheduled task, and set the execution interval.

6. Summary
Using PHP scripts to implement automated testing on Linux servers can improve the efficiency and quality of software development and reduce the possibility of repeated operations and human errors. This article introduces how to prepare work, write test cases, write automated test scripts, and regularly execute automated test scripts, and provides specific code examples. I hope this article can help everyone and promote the improvement and automation of the software development process.
