Slides in English.

Talk given à Devoxx Belgium and Droidcon Vienna

Transcript

1. DevOps on Android From one git push to a Play Store release @JeremMartinez www.jeremie-martinez.com
4. Processes depend on context
5. DevOps n.pr [dɛvops] Promotes a release process which bring together through communication and collaboration both development and operational teams. Play Store
6. Continuous integration Automated build Fail fast Constantly tested Constant packaging Easier release
7. Source of a solid process
8. Packaging Quality Tests Build Push
9. Push dev master v21 v22
10. Push feature dev master v21 v22
11. Push feature dev master v21 v22
12. Merge request mandatory At least one reviewer Merge always by the reviewer Branch must always be rebased Push
13. Build Push Packaging Quality Tests
14. Build 2 builds: debug and release
15. Build
16. Build Isolated builds Different architectures possible Empower developers
17. Packaging Quality Tests Build Push
18. Tests Yes, even on Android
19. JUnit4 public final class LordOfTheRingsTest {
 
 @Before
 public void setup() { … }
 
 @Test
 public void shouldBringThePrecious() { … } @After
 public void tearDown() { … } } Unit tests
20. Robolectric public final class LordOfTheRingsTest {
 
 @Before
 public void setup() { … }
 
 @Test
 public void shouldBringThePrecious() { … } @After
 public void tearDown() { … } } Unit tests
21. @RunWith(RobolectricTestRunner.class)
 @Config(manifest = Config.NONE) Unit tests Robolectric public final class LordOfTheRingsTest {
 
 @Before
 public void setup() { … }
 
 @Test
 public void shouldBringThePrecious() { … } @After
 public void tearDown() { … } }
22. Integration tests Espresso or Robotium
23. Integration tests Espresso or Robotium
24. Integration tests Only test main user-flows
25. Integration tests Search Cart Payment Tickets Example for Captain Train
26. Tests
27. Quality Tests Build Push Packaging
28. Quality
29. Quality Lint
30. Quality Lint Custom
31. Quality public class AttrPrefixDetector extends ResourceXmlDetector {
 
 public static final Issue ISSUE = Issue.create("AttrNotPrefixed", //
 "You must prefix your custom attr by `ct`", //
 "We prefix all our attrs to avoid clashes.", //
 Category.TYPOGRAPHY, //
 5, // Priority
 Severity.WARNING, //
 new Implementation(AttrPrefixDetector.class, // Scope.RESOURCE_FILE_SCOPE) // );
32. Quality // Only XML files
 @Override
 public boolean appliesTo(@NonNull Context context,
 @NonNull File file) {
 return LintUtils.isXmlFile(file);
 }
33. Quality // Only values folder
 @Override
 public boolean appliesTo(ResourceFolderType folderType) {
 return ResourceFolderType.VALUES == folderType;
 }
34. Quality // Only attr tag
 @Override
 public Collection<String> getApplicableElements() {
 return Collections.singletonList(TAG_ATTR);
 }
35. Quality // Only name attribute
 @Override
 public Collection<String> getApplicableAttributes() {
 return Collections.singletonList(ATTR_NAME);
 }
36. Quality @Override
 public void visitElement(XmlContext context, Element element) {
 final Attr attributeNode = element.getAttributeNode(ATTR_NAME);
 if (attributeNode != null) {
 final String val = attributeNode.getValue();
 if (!val.startsWith("android:") && !val.startsWith("ct")) {
 context.report(ISSUE,
 attributeNode,
 context.getLocation(attributeNode),
 "You must prefix your custom attr by `ct`");
 }
 }
 }
37. Quality public final class CaptainRegistry extends IssueRegistry {
 @Override
 public List<Issue> getIssues() {
 return Collections.singletonList(AttrPrefixDetector.ISSUE);
 }
 }
38. Quality
39. Quality Do not underestimate Lint rules
40. Packaging Quality Tests Build Push
41. Packaging Filter your resources Proguard Assemble Sign your APK Zipalign your APK zipalign -z 4 in.apk out.apk
42. Packaging Quality Tests Build Push Continuous integration
43. Packaging Quality Tests Build Push Continuous integration
44. Continuous integration
45. Automate releases in order to deliver quickly, easily and reliably Continuous integration Continuous delivery
46. Continuous deployment
47. « Too many updates »
48. Not enough content
49. Can ≠ Want
50. But … What is a release ?
51. Beta Rollout 5% Rollout 50% Release 100% 1 week 1 week
52. Beta Rollout 5% Rollout 50% Release 100% Every 6 weeks On Tuesday
53. Continuous integration Continuous delivery dev master v21
54. Publish Screenshots Continuous delivery
55. Screenshots Don’t neglect screenshots
56. Screenshots Automate screenshots
57. Home-made with UiAutomator Spoon by Square Screengrab by Fastlane Screenshots
58. Publish Continuous delivery Screenshots
59. Avoid bad surprises Publish
60. Check your permissions Publish
61. private static final String[] EXPECTED_PERMISSIONS = { … } @Test
 public void shouldMatchPermissions() throws Exception {
 final AndroidManifest androidManifest = new AndroidManifest( //
 Fs.fileFromPath("build/intermediates/manifests/full/debug/AndroidManifest.xml"), //
 null, //
 null //
 );
 final Set<String> requestedPermissions = new HashSet<>(androidManifest.getUsedPermissions());
 
 assertThat(requestedPermissions).containsOnly(EXPECTED_PERMISSIONS);
 } Publish
62. Tests database upgrades Publish
63. testCompile 'org.xerial:sqlite-jdbc:3.8.10.1'
 Publish
64. @Test
 public void upgradeShouldBeTheSameAsCreate() throws Exception {
 DbOpenHelper helper = new DbOpenHelper(RuntimeEnvironment.application);
 
 helper.onCreate(newDatabase());
 helper.onUpgrade(originDatabase(), 1, CURRENT_VERSION);
 
 Set<String> newSchema = extractSchema(newFile.getAbsolutePath());
 Set<String> upgradedSchema = extractSchema(upgradedFile.getAbsolutePath());
 
 assertThat(upgradedSchema).isEqualTo(newSchema);
 } Publish
65. connection = DriverManager.getConnection(JDBC_SQLITE + url);
 
 tables = connection.getMetaData().getTables(null, null, null, null);

 schema.add(tableType + " " + tableName);
 Publish
66. columns = connection.getMetaData().getColumns(null, null, tableName, null);
