BDD

TDD

mocking

BDD

Based on SpecFlow library and Gherkin

syntax

I forked SpecFlow and implemented

WP7 support. Will be merged into the

main trunk

We can’t operate with Views directly –

have to work with ViewModel

Call commands

Read/write properties

demo

BDD

TDD

Create a separate testing assembly

You can use one assembly as an entry

point (reduce number of apps on your

device)

You may tag your test methods

You may test internal methods

You may test asynchronous methods

Test methods may use additional

attributes

demo

TDD

Mocking

No native support in WP7 runtime

Should use Silverlight assemblies

Can’t add a reference to WP7

assembly

Some WP7 features are not available

(XNA)

WP7 specific classes should be

wrapped with the adapter pattern,

put into containers and used as

interfaces

demo

mocking

summary

Unit test tell you that you build the

system right

Acceptance tests tell you that you build

the right system

You can use either both kind of tests or

just one

Mocking for WP7 is not trivial but

possible
