This post is completely my personal memo. Recent kotlinx.coroutines has raising exception when runBlocking runs on a UI thread by default. The runBlocking is used to block current thread interruptibly until its completion. https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.experimental/run-blocking.html https://github.com/Kotlin/kotlinx.coroutines/blob/7764e43c6fe9640615747f7830e8aae1b9bc26d2/docs/basics.md#bridging-blocking-and-non-blocking-worlds In 0.25.0, the runBlocking has https://github.com/Kotlin/kotlinx.coroutines/issues/464 . As a workaround, we can disable the checker as below. https://github.com/Kotlin/kotlinx.coroutines/pull/458#issuecomment-408737581 https://github.com/Kotlin/kotlinx.coroutines/issues/227 [update]…More

[iOS]Mocking libraries for XCTest and XCUITest
When you run tests on iOS, you can mock HTTP request with several ways. We can use such mocking for XCUITest as well. For example, you can achieve the way using below libraries. https://github.com/envoy/Embassy https://github.com/envoy/Ambassador https://github.com/KazuCocoa/myCurrencyExchange/blob/master/myCurrencyExchangeUITests/ is the result. If you’d like to achieve similar things based on EarlGrey, you should switch the mocking libraries…More
[Android]Relax “Restrictions on non-SDK interfaces” on Android P
Android P has a feature of Restrictions on non-SDK interfaces. => https://developer.android.com/preview/restrictions-non-sdk-interfaces If you have a method like below, you will face java.lang.NoSuchMethodException: setAnimationScales [class [F] error. This is because of the non-sdk interface feature. https://github.com/KazuCocoa/DroidTestHelper/blob/3781fa40a6c9dfd34e1cb94ae230a98931af3313/droidtesthelperlib/src/main/java/com/kazucocoa/droidtesthelperlib/HandleAnimations.kt#L23 To avoid the error, we can call below adb commands. After this, calling setAnimationScales succeeds. I’ve appended the note…More
[Android]run tests on multiple emulators
I published x3 Speed Up Android CI at Cookpad last week. I’d like to leave the same thing in https://github.com/KazuCocoa/EspressoEnv/blob/master/script/run_instrumented_tests.sh The script is almost the same, but it has composer script as well.More
[Android][Espresso] Decrease test failure because of ARN dialog
When I ran android tests on OS 8.1 emulators, I faced some ARN dialog by Google bundled apps. They led test failure related with UI, Espresso, because of the dialog remained on the UI. To reduce the error, we can implement like below code in TestRunner. https://github.com/KazuCocoa/EspressoEnv/pull/8/files If the dialog appears before running tests, we…More
[iOS][Appium]How to debug, set break points, WebDriverAgent

The Rule work as @Rule in JUnit4. We’d like to clean screenshots every time. But we need some permissions to clean them. To achieve it, we can use PermissionRequester to get permissions. In…More
[iOS][Appium]Process Arguments by Appium for XCUITest, iOS
Today, I’d like to leave a tip. I’ve implemented test cases using this article for over 3 years. It helped us to control test environment more stable and fast. XCUITest can set process arguments for Instrumentation. According to https://github.com/appium/appium-xcuitest-driver#desired-capabilities, you can set processArguments in capability and the test app can get the value via ProcessInfo.…More
[Android]some mocking features work only on Android P+
One of my colleagues told me Mockk. The library is pure Kotlin mocking library. An interesting thing for me is Android instrumentation support. I had a question when I saw that why Android P was a limitation. Since it provide mocking feature for final classes / objects in instrumentation tests. I investigated a bit and…More
