Integration testing

Integration testing is the second level of the software testing process comes after unit testing.

Code coverage for integration tests, available in Go 1.20. In this blog post we’ll give an example of how these new features work, and outline some of the use cases and workflow for collecting coverage profiles from integration tests.

Flutter 2.5 What’s New

Flutter 2.5 is released on 8th September 2021. There are so many performance improvements in this release and we can easily track down performance problems in our app. Basically, Flutter 2.5 performance improvements are targeting iOS. Flutter apps built on the Apple silicon M1 Mac run on the ios simulator. It supports Full-Screen Android applications and improves improvements in scrolling, MaterialBanner support, etc.

Dart 2.14:

Flutter 2.5 comes with 2.14, The new release has new features like new formatting to make cascades clearer, new pub support for ignoring files, and languages features, including the return of the legendary triple shift operator. The best thing about dart 2.14 is that this release creates a standard set of hints shared between new dart and flutter projects that come out of the box.

Android Full-Screen Mode:

The big change in flutter 2.5 is full-screen mode support for apps running on android. There is Support for various screen modes, which affect the visibility of UI overlays such as status and bottom navigation bar. The following new enveloping modes:

Lean Back: Tap anywhere to display the system overlays.

Sticky: Swipe edge to display system overlays.

Sticky Immersive: Similar to immersive but framework handle to swipe.

Edge-to-Edge: To show the application components it uses transparent system overlays.

Material You Widgets:

Google’s latest version of material design is Material You. Material You added new shapes, themes, and dynamic color effects. Flutter 2.5 introduces new Material You support, including FAB size and more theming options. It’s not fully complete, still in progress.

Improvements in Scrolling:

Flutter 2.5 Another improvement is the addition of scroll metrics notifications, which provide notifications of scrollable areas even if the user is not scrolling.

MaterialBanner:

Another great contribution from the community is the addition of MaterialBanner support to ScaffoldMessenger. Flutter 2.0 release, ScaffoldMessenger presenting snackBars at bottom of the screen which is to alert users. In Flutter 2.5, you can now add a banner to the top of your scaffold that stays in place until the user release it.

Android studio/IntelliJ:

This releases many improvements to IntelliJ/Android studio, starting with the ability to run integration tests. Flutter devs can run integration tests throughout the project using the new IntelliJ/Android Studio plugin. Integration tests are whole-application tests that run on the device, live in the integration_test directory, and use the same testWidgets() functionality from the widget unit test. To connect the test to IntelliJ/Android studio, add a run configuration that launches integration tests and connects the device to use the test. Running the configuration allows you to run tests, including setting breakpoints, climbing steps, and more.

Testing microservices can be challenging because they are small, decoupled components interconnected through APIs and other web services. Each microservice is its unit, so testing them requires a more detailed and comprehensive approach than testing a monolithic application. This means that testing must cover the individual service and how they interact with each other. Additionally, microservices are often deployed in a distributed environment where they are subject to unpredictable network conditions and other environmental variables, so testing must also account for these factors. Finally, microservices are typically built on different technologies and programming languages, so testers must be familiar with the entire technology stack to test the system properly.

Integration test using contract-driven development is a method of testing software that focuses on verifying the interaction between two applications. This testing ensures that the two applications can communicate and exchange data as expected. The contract-driven approach requires that both applications define their desired behavior so that the integration tests can verify that the actual behavior matches the expected behavior. In addition, this approach helps to ensure that the two applications are compatible and that any changes made to either application will not break the integration. If you want to know about Contract-Driven development and testing, this article can help you.

The Testing Pyramid is a visual representation of the recommended balance between the types of software tests. It suggests that most tests should be unit tests, followed by fewer integration tests and the fewest end-to-end tests. Unit tests give the most coverage and should be used to test individual components or features, while integration tests check how those components interact. End-to-end tests are the most expensive and time-consuming and should be used to check the full application. This article compares the testing diamond with the testing pyramid and gives us some advice in software testing.

Test Driven Development has a lot of benefits, but from another perspective, you may find some downsides in this approach. For example, TDD requires more time and effort to implement, which can be costly for some businesses, or debugging can be difficult when tests are written before code, as it is more difficult to track down the source of an issue. This article has a different view of the TDD approach that is worth reading.
