+Convert [React Test Renderer](https://reactjs.org/docs/test-renderer.html) tree to a format compatible with [Jest snapshot testing](https://facebook.github.io/jest/docs/tutorial-react.html#snapshot-testing).  
+This is similar to [enzyme-to-json](https://github.com/adriantoine/enzyme-to-json).
+
+# Install
+
+```console
+$ npm i -D react-test-renderer-tree-to-json
+```
+
+# Usage
+
+Only for full rendering without key props.
+
+```jsx
+import React from "react";
+
+import TestRenderer from "react-test-renderer";
+import { treeToJSON } from "react-test-renderer-tree-to-json";
+
+import { mount } from "enzyme";
+import toJson from "enzyme-to-json";
+
+const Hoge = () => <div />;
+
+it("snapshot", () => {
+  const renderer = TestRenderer.create(<Hoge />);
+  const tree = renderer.toTree();
+  expect(treeToJSON(tree)).toMatchSnapshot();
+  // similar to
+  const wrapper = mount(<Hoge />);
+  expect(toJson(wrapper, { noKey: true })).toMatchSnapshot();
+});
+/*-----------------------
+exports[`snapshot 1`] = `
+<Hoge>
+  <div />
+</Hoge>
+`; 
+-----------------------*/
