Run your Flutter integration tests for iOS
Integration tests are used to test how individual code works together and to capture the overall performance of an app. The integration_test package, provided by Flutter, is used to write integration tests for your Flutter app.
Prerequisites
- Xcode to create and publish your app.
- Ensure that your application complies with Apple’s Review Guideline before starting the release process.
- You will need a BrowserStack
usernameandaccess key. To obtain your access credentials, sign up for a free trial or purchase a plan.
Prepare iOS Flutter test package for testing
Launch the Xcode Application.
On Xcode, open ios/Runner.xcworkspace in your app’s iOS folder.
Click File > New > Target.
In the Target window, create a new Target by clicking Unit Testing Bundle under the Test section.
Rename the Product Name to RunnerTests in the Target window. Set the Target to be Tested to Runner and set the language Objective-C.
Ensure that the iOS Deployment Target setting in the Build Settings section for the RunnerTests file matches the setting in the Runner file.
Add a test file RunnerTests.m to a new target file in Xcode. This file acts as the entry point for your tests and executes the flutter wrapper. Add the following code snippet to the file:
Upload your test package
Upload your iOS app test package (<ios_test_package_name> in step 9) in .zip format to BrowserStack servers using the REST API request.
The following sample cURL command shows how to upload the test package:
A sample response for the above request is as follows:
{
"test_package_name":"<ios_test_package_name>.zip",
"test_package_url":"bs://3f8ca850476a7c26d4698225e32b353c83cac7ed",
"test_package_id":"3f8ca850476a7c26d4698225e32b353c83cac7ed",
"uploaded_at":"2022-07-21 14:55:59 UTC",
"expiry":"2022-08-20 14:55:59 UTC",
"framework":"flutter-integration-tests",
}
The value of the test_package_url parameter in the response is used to specify the application under test when you run your package.
Run iOS Flutter integration tests
After you upload your test package to BrowserStack servers, send an API request to start the test execution as shown in the following sample cURL request:
A sample response for the request is as follows:
{
"message": "Success",
"build_id": "f6f6d4214ebc3ccab9814d8090f5838644b0dc72"
}
The build_id is used to uniquely identify your build in App Automate.
View test results
After you start Flutter integration tests execution using the REST API, visit your App Automate dashboard to view your test results, debugging logs, and overall test details.
