+## End-to-end testing
+
+We use the Selenium test framework to test our app.
+
+In order to run the test, first we need to download a webdriver executable.
+
+Microsoft Edge's webdriver can be downloaded from [microsoft-edge-tools-webdriver](https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/). Make sure the version we download matches the version of the web browser installed on our laptop.
+
+After extracting the downloaded zip file (e.g., edgedriver_win64.zip), rename msedgedriver.exe to MicrosoftWebDriver.exe.
+
+Add MicrosoftWebDriver.exe's path to system's PATH variable.
+
+Install the following dependencies too:
+
+- pip install -U selenium==3.141.0
+- pip install -U urllib3==1.26.2
+
+Run English Pal first, then run the test using pytest as follows: pytest --html=pytest_report.html test_add_word.py
+
+The above command will generate a HTML report file pytest_report.html after finishing executing test_add_word.py.  Note: you need to install pytest-html package first: pip install pytest-html.
+
+You may also want to use [webdriver-manager](https://pypi.org/project/webdriver-manager/) from PyPI, so that you can avoid tediously installing a web driver executable manually.  However, my experience shows that webdriver-manager is too slow.  For example, it took me 16 minutes to run 9 tests, while with the pre-installed web driver executable, it took less than 2 minutes.
