Getx Test

getx_test is a package that provides testing utilities for GetX, a powerful state management library for Flutter.
Based on get_test library.

Installation

Add the following dependency to your pubspec.yaml file:

dependencies:  
    getx_test: ^1.0.3

Usage

Import the required packages and create a test case using the getTest method. Inside the widgetTest callback, use the expect method to test your GetX app's behavior.

import 'package:flutter/material.dart';  
import 'package:flutter_test/flutter_test.dart';  
import 'package:get/get.dart';  
import 'package:getx_test/getx_test.dart';  
  
void main() {  
    getTest(  
    "test description",  
    widgetTest: (tester) async {  
	    expect('/', Get.currentRoute);  
	    
	    Get.to(Container()); 
	    expect('/Container', Get.currentRoute);  
	    
	    Get.to(Scaffold()); 
	    expect('/Scaffold', Get.currentRoute);  
	    
	    Get.back();  
	    expect('/Container', Get.currentRoute); 
	});  
}

You can also use testGetX, testGetBuilder, and testObx to test specific GetX widgets:

testGetX(  
  'GetX test',  
  widget: GetX<Controller>(  
    init: Controller(),  
    builder: (controller) {  
      return Text("Clicks:${controller.count}");  
    },  
  ),  
  test: (e) {  
    expect(find.text("Clicks:0"), findsOneWidget);  
    expect(e.count.value, 0);  
  },  
);

testGetBuilder(  
  'GetBuilder test',  
  widget: GetBuilder<Controller>(  
    init: Controller(),  
    builder: (controller) {  
      return Text("Clicks:${controller.count}");  
    },  
  ),  
  test: (e) {  
    expect(find.text("Clicks:0"), findsOneWidget);  
    expect(e.count.value, 0);  
  },  
);

testObx(  
  'Obx test',  
  widget: (controller) => Obx(  
    () => Text("Clicks:${controller.count}"),  
  ),  
  controller: Controller(),  
  test: (e) {  
    expect(find.text("Clicks:0"), findsOneWidget);  
    expect(e.count.value, 0);  
  },  
); 

Finally, you can test your GetxController instances with testController:

testController<Controller>(  
  'Controller test',  
  (controller) {
	  //Write your controller arrangements, actions and assertions here...
  },  
  controller: Controller(),  
  onInit: (c) {  
    c.increment();  
    print('onInit');  
  },  
  onReady: (c) {  
    print('onReady');  
    c.increment();  
  },  
  onClose: (c) {  
    print('onClose');  
  },  
);
