By default, PHPUnit CLI only executes test classes with names that end in "Test". Name your class "TestClassX.php", for instance, and it will be
skipped.
This rule raises an issue for each test class with a name not ending in "Test".
Noncompliant Code Example
class TestClassX extends PHPUnit\Framework\TestCase { // Noncompliant
public void testDoTheThing() {
//...
Compliant Solution
class ClassXTest extends PHPUnit\Framework\TestCase {
public void testDoTheThing() {
//...
