assertStringStartsWith after assertNotEmpty fails with error "Parameter #1 $prefix of method PHPUnit\Framework\Assert::assertStringStartsWith() expects non-empty-string', while the string cannot be empty due to the assertNotEmpty call.

<?php use PHPUnit\Framework\TestCase; class FooTest extends TestCase { public function testFoo(): void { $string = ([ '', 'bar', ])[rand(0, 1)]; $this->assertNotEmpty($string); $this->assertStringStartsWith($string, 'baz'); } }
