+## テストの走らせ方
+### 仮想ディスプレイのインストールと立ち上げ
+```bash
+sudo apt-get install xvfb
+/sbin/start-stop-daemon --start --quiet --pidfile /tmp/custom_xvfb_99.pid --make-pidfile --background --exec /usr/bin/Xvfb -- :99 -screen 0 1400x900x24 -ac +extension GLX +render # copy from pyqtgraph .travis.yaml
+export DISPLAY=:99.0
+```
+
+### テストの実行
+1. 全部をテスト
+```bash
+python test_all.py
+```
+2. 個別にテスト
+```bash
+python test_xxx.py
+```
+
+## テストのTips
+- unittestのパッケージを使用.  
+- pytestは，catkinとの相性が良くない模様．(devel以下の`__init__.py`の読み込みでエラーが出る)  
+- テストを作るには，unittest.TestCaseを継承したクラスに，test_xxxという名称のメソッドを定義して作る，  
+- テストを走らせるには，`unittest.main()`を実行すると，`test_xxx`メソッドを順に実行してくれる．  
+- assertionは，unittest.TestCaseのメソッドである，assertXXXを利用するとテストが失敗したときに見やすく表示される．
+
+```python
+import unittest
+
+class TestXXX(unittest.TestCase):
+    def test_hogehoge(self):
+        # write test here
+        x = 1
+        self.assertEqual(x,1,'x is {}. not 1'.format(x))
+
+if __name__ == '__main__':
+    unittest.main()
+```
+- `unittest.main`はテストが終わると，そのまま`exit`しようとするが，ガーベジコレクションの順番によって時々Segmentation Faultが発生する．  
+以下のようにテスト終了後に`QtGui.QApplication`の消去を明示的に行うとエラーが消えた．
+```python
+if __name__ == '__main__':
+    app = pyqtgraph.Qt.QtGui.QApplication([])
+    try:
+        unittest.main()
+    finally:
+        del app
+```
