HW1.P2 - Testing

In this homework assignment, you will be doing all things testing. You learn and practice several skills for unit testing, mocking, and browser testing.

Part 1 - Twitter (40 points)

Using twitter4j, you will write a simple twitter analytics tool.

BUT, there is no api token configurd for the tool. You'll have to find out how to write code using this api without ever getting real tweets. HOW? By using Mockito

The code repo has started with a basic stub and unit test. public Status mostRetweeted(List<Status> list)

Complete the implementation and unit tests for the following functions. Use a TDD style approach to help you develop and test out your functions (10 points each -- including unit tests):

• public Status leastRetweeted(List<Status> list)
• public String mostRetweetedPhoto(List<Status> list) Return url of most retweeted photo in a single tweet. Use MediaEntity.getMediaURL(). That is, for all tweets that contain a photo, which one has the highest retweet count?
• public String mostTweetedPhoto(List<Status> list) Return url of most tweeted photo across all tweets. For example, 2 different pictures of octocat is shared by many people across many tweets. Which photo was most posted, including retweets counts?
• public int mostCommonWord(List<Status> list) Return the most frequent occurrence of a word in a across all statuses.

Twitter

Part 2 - Selenium (40 points)

You will help test out a survey hosting site, http://checkbox.io

Write unit tests that verify the following: http://checkbox.io/studies.html

• The participant count of "Frustration of Software Developers" is 55
• The total number of studies closed is 5.
• If a status of a study is open, you can click on a "Participate" button.
• You can enter text into this study (don't actually submit, or you can't run test again!): http://checkbox.io/studies/?id=569e667f12101f8a12000001

You'll have to adjust the driver used in order to properly render javascript:

	private static WebDriver driver;
	
	@BeforeClass
	public static void setUp() throws Exception 
	{
		//driver = new HtmlUnitDriver(true);
		//System.setProperty("webdriver.chrome.driver", "/Users/gameweld/classes/326/HW1.P2/hw1p2/chromedriver");
		ChromeDriverManager.getInstance().setup();
		driver = new ChromeDriver();
	}
	
	@AfterClass
	public static void  tearDown() throws Exception
	{
		driver.close();
	}

Add the following maven dependency:

	<dependency>
  		<groupId>io.github.bonigarcia</groupId>
  		<artifactId>webdrivermanager</artifactId>
  		<version>1.3.1</version>
	</dependency>    

Part 3 - iTrust (20 points)

You simply must get all iTrust unit tests passing.

Use all available resources to make this happen. This is the last chance before we go full iTrust.

Errors

The output of the failing error cases are very helpful. If you can't get a connection to a db, you need to start your mysql service. If you can't find a web element, you don't have tomcat/iTrust running. If you see an invalid "0000-00" date, then you need to update mysql settings related to date:

• Check out https://github.com/CSC-326/AutoInstall/ you're having trouble getting your env setup.
• You might have to manually reset mysql and tomcat if you've had the service running long-term.
• If you are running mysql 5.7.10 (latest), make sure you set my.ini to avoid date errors:

[mysqld]
sql_mode = ""

Submission

1. Add your TA to your repo.
2. Use git remote set-url origin to update your new repo. See https://help.github.com/articles/changing-a-remote-s-url/
3. Commit your code for your twitter unit tests.
4. Include a HW1.P2.md, which includes
   • a short description of your homework assignment
   • your code and unit tests!
   • a screen shot of your passing twitter tests
   • a screen shot of your passing web tests
   • a screen shot of your passing iTrust test cases.
5. On moodle, submit the link to this repo.
