3. Do we need to do a test?
4. Application Development Cycle Specifications of the application Write the codes Test the application manually
5. New Feature New Bugs . . . https://gph.is/2jt9RvW
6. And then . . . Automatic Testing such as unit testing and instrumentation testing. • Write the main code • Write the test code
7. TDD (Test Driven Development) is an application development method developed by testing. • Writing Tests • Running Tests • Write down the Code • Running Tests • Refactor Code
8. Advantages of using TDD • More Productive • Code is neater • Safer Refactoring • Minimizing Bugs • Documentation
9. Understand the Testing Pyramid Illustrates how your app should include the three categories of tests: small, medium, and large https://developer.android.com/training/testing/fundamentals
10. Unit Testing? Unit Testing is useful for testing code logic in our application.
11. Example UnitTest
12. Spek Spek is a specification framework that allows you to easily define specifications in a clear, understandable, human readable way. https://spekframework.org
13. Style of Spek • given, on, it • describe, it
14. given, on, It • name = name of class • given = context • on = action • it = actual test
15. example
16. describe, it • name = name of class • describe = context • it = actual test
17. example
18. Setting up • org.jetbrains.spek:spek-api:1.1.5 • org.jetbrains.spek:spek-junit-platform-engine:1.1.5 • org.junit.platform:junit-platform-runner:1.0.0 @RunWith(JUnitPlatform::class) class CalculatorSpec: Spek({ ... })
19. And then . . .
20. And then . . .
21. Migrating to Spek 2.x from 1.x testImplementation 'org.spekframework.spek2:spek-dsl-jvm:2.0.0-rc.1' testImplementation 'org.spekframework.spek2:spek-runner-junit5:2.0.0-rc.1'
22. Style of Spek 2.x • given, on, it • describe, context, it
