The chapter's exercises

1. The first safety net

   Exercise 1 · 220 XP · 4 objectives checked by tests

   Gorm has done the math. Since the website opened, Pippin has “improved” the tavern four times, and four times everything broke. Each time, they only found out because a customer complained.

   WebTestCasecreateClient()submitFormAssertions

2. Data to test with

   Exercise 2 · 230 XP · 4 objectives checked by tests

   Gorm's second project: the menu for a budget (/menu?budget=5). Broke adventurers count on it: no way it should offer them a stew at 12 gold pieces.

3. The bill, please

   Exercise 3 · 230 XP · 5 objectives checked by tests

   No more mental arithmetic: Gorm has had an Addition (bill) service written, which calculates each table's bill. Its rules fit in three lines:

   Unit testTestCase#[DataProvider]expectException

4. Who is allowed?

   Exercise 4 · 240 XP · 5 objectives checked by tests

   The tavern's security has already given way once (remember the stolen keys). Now Gorm wants tests that check every access rule, for every role:

   loginUser()Security tests401 / 403Roles and voters

5. Testing the API

   Exercise 5 · 240 XP · 5 objectives checked by tests

   The scrolls' API has become the tavern's main reservation channel. A regression there would be costly. And a leak of a guild's seal would be even costlier.

6. 🐉 Boss: the lying tests

   Exercise 6 · 300 XP · 5 objectives checked by tests

   Pippin has heard about tests. He wrote some, proudly: “All green, boss!”
