+# PHPUnit Patch Serializable Comparison [![Build Status](https://travis-ci.com/mpyw/phpunit-patch-serializable-comparison.svg?branch=master)](https://travis-ci.com/mpyw/phpunit-patch-serializable-comparison) 
+
+Fixes `assertSame()`/`assertEquals()` serialization errors running in separate processes.
+
+## Requirements
+
+- php: `>=5.3.3`
+- [phpunit/phpunit](https://github.com/sebastianbergmann/phpunit): `>=4.8.0`
+- [sebastianbergmann/comparator](https://github.com/sebastianbergmann/comparator): `^1.0 || ^2.0 || ^3.0 || ^4.0`
+
+## Installing
+
+```bash
+composer require --dev mpyw/phpunit-patch-serializable-comparison
+```
+
+## Example
+
+```php
+class AssertionTest extends TestCase
+{
+    protected function callAssertSameInClosure(\Closure $closure)
+    {
+        static::assertSame('aaa', 'bbb');
+    }
+
+    /**
+     * @runInSeparateProcess
+     * @preserveGlobalState disabled
+     */
+    public function testAssertionIncludingUnserializableTrace()
+    {
+        static::callAssertSameInClosure(function () {});
+    }
+}
+```
+
+### Before Patching
+
+```
+PHPUnit\Framework\Exception: PHP Fatal error:  Uncaught Exception: Serialization of 'Closure' is not allowed in Standard input code:XX
+Stack trace:
+#0 Standard input code(XX): serialize(Array)
+#1 Standard input code(XX): __phpunit_run_isolated_test()
+#2 {main}
+  thrown in Standard input code on line XX
+```
+
+### After Patching
+
+```diff
+Failed asserting that two strings are identical.
+--- Expected
++++ Actual
+@@ @@
+-'aaa'
++'bbb'
