Rule php_unit_construct

PHPUnit assertion method calls like ->assertSame(true, $foo) should be written with dedicated method like ->assertTrue($foo).

Warning

Using this rule is risky

Fixer could be risky if one is overriding PHPUnit’s native methods.

Configuration

assertions

List of assertion methods to fix.

Allowed values: a subset of ['assertEquals', 'assertNotEquals', 'assertNotSame', 'assertSame']

Default value: ['assertEquals', 'assertSame', 'assertNotEquals', 'assertNotSame']

Examples

 final class FooTest extends \PHPUnit_Framework_TestCase {
     public function testSomething() {
-        $this->assertEquals(false, $b);
-        $this->assertSame(true, $a);
-        $this->assertNotEquals(null, $c);
-        $this->assertNotSame(null, $d);
+        $this->assertFalse($b);
+        $this->assertTrue($a);
+        $this->assertNotNull($c);
+        $this->assertNotNull($d);
     }
 }

     public function testSomething() {
         $this->assertEquals(false, $b);
-        $this->assertSame(true, $a);
+        $this->assertTrue($a);
         $this->assertNotEquals(null, $c);
