I am using PHP 7.0 and executing tests cases with PHPunit. those are working fine. but when trying to run PHPUnit with --coverage-html option using PHPUnit 6.3.0 or 5.7.23, but it just displays available options rather than generating code coverage report.
I am not using any phpunit.xml file, is that mandatory and if yes then how to put my directory. I have two folders in my project - one for lib (core php class files) and another one for tests which has unit test cases.
Supposing your code is inside standard directories (e.g. src for code and tests for tests), use the following phpuni.xml.dist file
<?xml version="1.0" encoding="UTF-8"?>
<!-- https://phpunit.de/manual/current/en/appendixes.configuration.html -->
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/7.0/phpunit.xsd"
backupGlobals="false"
colors="true"
bootstrap="vendor/autoload.php"
>
<testsuites>
<testsuite name="Project Test Suite">
<directory>tests</directory>
</testsuite>
</testsuites>
<filter>
<whitelist>
<directory>src</directory>
</whitelist>
</filter>
</phpunit>
then you can run phpunit to get tests without coverage and phpunit coverage-html build to get tests with coverage (feel free to replace build with any directory name you like)
--coverage-htmlrequires an argument -- the directory to store the coverage report in.
