+Write Assertions about Deprecations
+-----------------------------------
+
+When adding deprecations to your code, you might like writing tests that verify
+that they are triggered as required. To do so, the bridge provides the
+``@expectedDeprecation`` annotation that you can use on your test methods.
+It requires you to pass the expected message, given in the same format than for
+the `PHPUnit's assertStringMatchesFormat()`_ method. If you expect more than one
+deprecation message for a given test method, you can use the annotation several
+times (order matters)::
+
+    /**
+     * @group legacy
+     * @expectedDeprecation This "%s" method is deprecated.
+     * @expectedDeprecation The second argument of the "%s" method is deprecated.
