Exercise 3: Remove Duplication

1. Checkout branch 03_remove_duplication.
2. Open CheckoutFeatureTest in src > test > java > exercises. There is duplicate code that exists in LoginFeatureTest, specifically the setup() and teardown() methods.
3. Create a BaseTest class that executes these prerequisite and postrequisite test actions.
4. Migrate the setup() and teardown() methods from LoginFeatureTest and CheckoutFeatureTest and place them into BaseTest
5. Back in LoginFeatureTest and CheckoutFeatureTest, extend BaseTest like so:

   public class LoginFeatureTest extends BaseTest {
   ...
   }
   

6. Also in LoginFeatureTest and CheckoutFeatureTest remove the following line:

   protected WebDriver driver
   

   as it's now redundant.
7. Delete FullJourneyTest and test the changes:

   mvn test
   

8. If both tests run fine, use git commit or git stash, then checkout the next branch to proceed to the next exercise:

Part Two: Cross Browser Testing

Next we will update our capabilities in BaseTest to test using the latest version of Google Chrome, which means we have to modify our code a bit to comply with the new W3C protocol.

1. Add a second MutableCapabilities object in the setup() method with the following details:

   MutableCapabilities sauceOpts = new MutableCapabilities();
   sauceOpts.setCapability("username", sauceUsername);
   sauceOpts.setCapability("accessKey", sauceAccessKey);
   sauceOpts.setCapability("name", method.getName());
   sauceOpts.setCapability("seleniumVersion", "3.141.59");
   sauceOpts.setCapability("build", "saucecon19-best-practices");
   sauceOpts.setCapability("tags", "['best-practices', 'saucecon19']");
   

2. Next, modify the existing MutableCapabilities object called `capabilities with the following:

   MutableCapabilities capabilities = new MutableCapabilities();
   capabilities.setCapability(ChromeOptions.CAPABILITY,  chromeOpts);
   capabilities.setCapability("sauce:options", sauceOpts);
   capabilities.setCapability("browserName", "googlechrome");
   capabilities.setCapability("browserVersion", "71.0");
   capabilities.setCapability("platformName", "windows 10");
   

3. Run a test to ensure the build passes

   mvn test
   

4. Use git stash or git commit to discard or save your changes. Checkout the next branch to proceed to the next exercise

   git checkout 04_configure_atomic_tests
