1. DevOps sur Android D'un git push à une release sur le Play Store @JeremMartinez www.jeremie-martinez.com
2. Nous recrutons !
3. Les processes dépendent du contexte
4. DevOps n.pr [dɛvops] Fluidifier le processus de mise en production en rassemblant les équipes de développement et les équipes opérationnelles. Play Store
5. Intégration continue Livraison continue Déploiement continu Tests unitaires Automatisation Release Packaging Build Tests d’intégration Test d’instrumentation Quality
6. Intégration continue Build automatique Fail fast Testé constamment Packaging constant Release plus facile
7. Base d’un process solide
8. Packaging Quality Tests Build Push
9. Push dev master v19 v20
10. Push dev master v19 v20 feature
11. Build Push Packaging Quality Tests
12. Build 2 builds: debug et release
13. Build
14. Packaging Quality Tests Build Push
15. Tests Oui, même sur Android
16. Tests unitaires Valider des fonctionnalités Garantir des comportements Empêcher les regressions
17. JUnit4 public final class LordOfTheRingsTest {
 
 @Before
 public void setup() { … }
 
 @Test
 public void shouldBringThePrecious() { … } @After
 public void tearDown() { … } } Tests unitaires
18. Robolectric public final class LordOfTheRingsTest {
 
 @Before
 public void setup() { … }
 
 @Test
 public void shouldBringThePrecious() { … } @After
 public void tearDown() { … } } Tests unitaires
19. @RunWith(RobolectricTestRunner.class)

 @Before

 @Test
 public void shouldBringThePrecious() { … } @After

20. @Test
 public void shouldRestoreFromParcelable() { // Given Character item = new Character("Frodo", "Baggins", "Hobbit"); 
 // When
 Parcel parcel = Parcel.obtain();
 item.writeToParcel(parcel, 0);
 parcel.setDataPosition(0); // Then Character fromParcel = Character.CREATOR.createFromParcel(parcel); assertThat(fromParcel.firstname).isEqualTo("Frodo"); assertThat(fromParcel.lastname).isEqualTo("Baggins");
 assertThat(fromParcel.race).isEqualTo("Hobbit"); } Tests unitaires
21. Ne testez pas Android Tests unitaires
22. Utilisez un framework d’assertions Truth ou AssertJ par exemple Tests unitaires
23. Tests d’intégration Espresso ou Robotium
24. Tests d’intégration Espresso ou Robotium
25. Tests d’intégration Testez uniquement les user-flows principaux
