+Mock constructors
+-----------------
+
+New in [v2.11.0](https://github.com/vektra/mockery/pull/406).
+
+Mockery v2.11 introduces constructors for all mocks. This makes instantiation and mock registration a bit easier and
+less error-prone (you won't have to worry about forgetting the `AssertExpectations` method call anymore).
+
+Before v2.11:
+```go
+factory := &mocks.Factory{}
+defer factory.AssertExpectations(t)
+```
+
+You can use the type-safe expecter interface as such:
+```go
+factory := mocks.NewFactory(t)
+```
+
+The `AssertExpectations` method is registered automatically inside the constructor via `t.Cleanup()` method.

 | `--case` | mockery generates files using the casing of the original interface name.  This can be modified by specifying `--case underscore` to format the generated file name using underscore casing. |
 | `--print` | Use `mockery --print` to have the resulting code printed out instead of written to disk. |
 | `--exported` | Use `mockery --exported` to generate public mocks for private interfaces. |
