How to compare 2 URL adres with PHPUnit? - php

Question

I am working on a task that is expose a xml file with given url. I want to test my code and I do this with PHPUnit. I used composer to install PHPUnit.
The example test that I want to run is this :
<?php
use PHPUnit\Framework\TestCase;
class IndexTest extends TestCase{
public function testGetXmlWithUrl(){
require 'index.php';
$XmlClass = new XmlReaderClass("localhost", "8000", "status.xml", "");
$url= $XmlClass->$url;
$myUrl = "http://localhost:8000/status.xml?password=";
$this->assertEquals($myUrl, $url);
}} ?>
TestCase class cannot be added. I mean even PhpUnit name is not colored in blue in the code. So I guess I could not include it in my project actually. Error is like:
Fatal error: Uncaught Error: Class 'PHPUnit\Framework\TestCase' not found in /Users/demetsen/Desktop/tests/IndexTest.php:4
My second problem is when I try to run testGetXmlWithUrl() method the result is :
Failed asserting that SimpleXMLElement Object (...) matches expected '\n ....
Why am I getting this result and how can I solve it?

A default phpunit.xml (or better, use phpunit.xml.dist, so you can copy/edit it locally if needed), can be created with phpunit --generate-configuration will include a line for bootstrap:
<phpunit
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/6.3/phpunit.xsd"
bootstrap="path/to/bootstrap.php"
<!-- more lines -->
</phpunit>
Here, the bootstrap="...." line can, at its simplest, point to the composer autoloader. PHPunit can also create a suitable file for you.
$ php ./phpunit-9.2.phar --generate-configuration # or vendor/bin/phpunit, via composer
PHPUnit 9.2.6 by Sebastian Bergmann and contributors.
Generating phpunit.xml in /home/username/code/test
Bootstrap script (relative to path shown above; default: vendor/autoload.php):
Tests directory (relative to path shown above; default: tests):
Source directory (relative to path shown above; default: src):
Generated phpunit.xml in /home/username/code/test
# optional, but useful:
# mv phpunit.xml phpunit.xml.dist # .dist will be read if .xml does not exist
The output file:
$ cat phpunit.xml
<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/9.2/phpunit.xsd"
bootstrap="vendor/autoload.php"
executionOrder="depends,defects"
forceCoversAnnotation="true"
beStrictAboutCoversAnnotation="true"
beStrictAboutOutputDuringTests="true"
beStrictAboutTodoAnnotatedTests="true"
verbose="true">
<testsuites>
<testsuite name="default">
<directory suffix="Test.php">tests</directory>
</testsuite>
</testsuites>
<filter>
<whitelist processUncoveredFilesFromWhitelist="true">
<directory suffix=".php">src</directory>
</whitelist>
</filter>
</phpunit>
If you had something you needed to add to the bootstrap process, create a file with your needs, and you'd probably also add something like require __DIR__.'/vendor/autoload.php'; to setup the autoloading.
