DIY: Set up test environment (JUnit)

Please try to set up the test environment (JUnit) before class. The class discussion will be more effective and enjoyable if your environment is readily available.

https://junit.org/junit5/

You are recommended to use Eclipse; JUnit 5 comes with it. (Note: You may use any Java IDE or command line, and set up / set class path JUnit)

There are a number of good tutorials on how to set up (or use) JUnit 5, such as https://blog.codefx.org/libraries/junit-5-setup/ and https://www.eclipse.org/community/

If you do not already have Java on your machine, download and install it. JUnit 5 requires Java 8 or higher.

DIY: Set up test environment (Selenium)

Please try to set up the test environment (Selenium) before class. Class discussion will be more effective and enjoyable if your environment is readily available.

https://www.selenium.dev/

There are a number of good tutorials on how to set up and use Selenium.

You may follow Get started with Selenium to set up your test environment.

How do you know if your test environment works?
Try running the provided test template. You should see a web browser open and close. The test should pass.

Note: the templates were created for Mac. For Windows users, please verify the paths to your browser driver and attach .exe to your drivers


Chrome driver installation with Selenium

Thanks to Andrea Jerausek, a CS 3250 TA, for creating the installation tutorial (for Windows)


JUnit/Selenium setup and troubleshooting

Thanks to all the CS 3250 teaching teams for sharing their experience. Special thanks to Jonah Kim for creating detailed instructions on the installation.

If you are familiar with Gradle, Maven, Ant, or any dependency management tools/frameworks, and prefer to use them to set up your Selenium, please feel free to use them instead of manually setting up Selenium. We choose not to introduce them in class to minimize additional tools/frameworks/software that you need to deal with.
