reflect & share (20 mins)

how to apply (20 mins)

experience test-driven development

understand the principles behind TDD

explore how the principles apply to your work

become an expert in TDD

be able to teach devs TDD

apply TDD in your daily work

think of the next step

write a failing test

run the test(s) => red

write just enough code to get the test to pass

run the test(s) => green

refactor => refactor

run the test(s)

The Art of Agile Development (2nd ed.) - James Shore

1. Obvious Implementation

2. Fake It 'Til You Make It

3. Triangulation

1, 2, Fizz, 4, Buzz, Fizz, 7, 8, Fizz, ...

def test_fizzbuzz_1():
	assert fizzbuzz(1) == 1

def fizzbuzz(length):
	return 1
					

1, 2, Fizz, 4, Buzz, Fizz, 7, 8, Fizz, ...

def fizzbuzz(length):
	if length == 1:
		return "1"
	else:
		return "1,2"

def test_fizzbuzz_1():
	assert fizzbuzz(1) == "1"

def test_fizzbuzz_2():
	assert fizzbuzz(2) == "1,2"
					

*3*5*7*9*

an exercise in programming
which helps hone your skills
through practice and repetition

disable your coding assistant (if any)

work in pairs or on your own

starting point:
a function/method that returns an empty string
a (failing) test for a counterstring of length 1

reference implementation:
https://smallsheds.garden/counterstring

decide on the next small step

write a failing test

change the code to make the test pass

refactor if it makes sense

share with another person/group

and another person/group

What was different?
What was the same?

What kinds of code do you write?

three groups

rotate after 5 minutes

one person stays for a next round

summary at the end

size of steps depends on length feedback loop

size of steps depends on level of confidence

amount of refactoring depends on level of experience
