Test exercises for practicing TDD

Counter

Counter is a simple web app that is used to increment and decrement a number.

Stage A

• WHEN a user clicks the Increment button then the number SHOULD increment by one.
• WHEN a user clicks the Decrement button then the number SHOULD decrement by one.

Note: Initial number is predefined
Note: ReactJS & HTML, Test Driven Development (Jasmine, Jest, Ava). No CSS

Acceptance Criteria:

• A test suit SHOULD check for basic functionality

---

Stage B

• WHEN a user clicks the Increment button then the number SHOULD increment by one.
• WHEN a user clicks the Decrement button then the number SHOULD decrement by one.

Note: Initial value SHOULD come from a mocked backend API.
Note: ReactJS & HTML, Test Driven Development (Jasmine, Jest, Ava)

Acceptance Criteria:

• A test suit SHOULD check for basic functionality
• A test suit SHOULD check for mocked number functionality

---

Stage C

• WHEN a user clicks the Increment button then the number SHOULD increment by one.
• WHEN a user clicks the Decrement button then the number SHOULD decrement by one.
• WHEN a user clicks the Randomize button then the number SHOULD be replaced by a random number.

Note: Initial value SHOULD come from a mocked backend API.
Note: ReactJS & HTML, Test Driven Development (Jasmine, Jest, Ava)

Acceptance Criteria:

• A test suit SHOULD check for basic functionality
• A test suit SHOULD check for mocked number functionality
• A test suit SHOULD check for randomizer functionality
