Getting Started

1. Install Flutter SDK -> https://flutter.dev/docs/get-started/install
2. Install Android Studio -> https://developer.android.com/studio
3. Get Emulator to test
   • Open Android Studio
   • Click Conigure -> AVD Manager
   • Create Virtual Device
   • Start the virtual Device
4. Clone the Project at this Commit --> https://github.com/HitMan1206/se_eportfolio_example/tree/11251e8d6fed877389d1f188e2600e27df3d94f5
5. Open it in IntelliJ
6. Choose in the Project Settings the Flutter SDK as Project SDK
7. run "flutter pub get"

Task

If everything works try to write Tests for the Classes and Widgets.

An example of possible Tests you can find here -> https://github.com/HitMan1206/se_eportfolio_example

Tutorial for Demo Tests

1. Add the following dependencies to your pubspec.yaml

   

2. Run flutter pub get

3. Start writing Tests

Unit Test

• All tests have to be in the test folder

• All tests have to end with _test.dart

• All test files need a main function

• Compare values with the expect function

  

• Execute tests from your flutter root with the command flutter test

Widget Test

• All tests have to be in the test folder

• All tests have to end with _test.dart

• All test files need a main function

• Compare number of found widgets with the expect function

• Find widgets with a Finder (e.g. find.text("text of the searched widget"))

  

• Execute tests from your flutter root with the command flutter test

Integration Test

• All tests have to be in the Test_driver folder

• Execute tests from your flutter root with the command flutter drive --target=test_driver/app.dart

• Executing only works with a running system (e.g. an emulator)

• Each test needs two files

  1. Executable File (named like you want, e.g. app.dart)

     --> Contains everything to execute the test. It sets up the test and runs the app. Minimal file is as follows

     

  2. Test File (named 'executable'_test.dart, e.g. app_test.dart)

     --> Contains the tests you want to execute on your app. Structure is similar to an unit test.

     

Finding a Widget

• Give your Widget a key

  

• Use method byValueKey to find it

  

Interacting with a Widget

• Tap it: driver.tap(widget)

• Get text: driver.getText()

• Write to a currently focused text field: driver.enterText("text to enter")

• Move a Widget: driver.drag(widget, offset)
