BUILD

Project 6 - URL Game

• Solve URL type puzzles
• 10 Correct in a row
• Typically requires about 50 attempts

Project 6 - Superhero Page

• Build a page "bacs200/Superhero"
• Table 5x5
• Images stored in "bacs200/images"

Test Cases

• All testing should be done with specific test cases
• Each test case either passes or fails
• Examples:
  • There is a page at bacs200/index.html
  • It has a title of Student Profile
  • It contains an image
  • It contains a bullet list of projects
  • It contain 500 words of text

Manual Testing

• A human visits each page and decides pass/fail for each test case
• This testing should be scripted
• Create a page to jump to each place on your website

Automated Testing

• Software tools can visit pages
• Pages can be searched for specific content

Project Page Tester

• Project Tests
• See if you can pass all of the tests
• Eventually this will be required
• This code may still have a few problems so don't worry if you can't solve every test
