Use Kotlin scripts and Clova SDK to build your Clova extension
Use Kotlin scripts and Clova SDK to build your Clova extensionLINE Corporation The document discusses using Kotlin scripts to create a Clova client. It shows how to evaluate Kotlin code from a script using a ScriptEngine to define a Clova client configuration with launch, intent, and session ended handlers. The Clova client created in the script can then be used to handle Clova requests and responses.
The Magic of LINE 購物 Testing
The Magic of LINE 購物 TestingLINE Corporation LINE Shopping provides an e-commerce platform in Taiwan. It has over 9 million monthly visitors, a 40% repurchase rate, and lists over 26 million products from over 1,300 brands. The document discusses how to test the LINE Shopping platform, including unit, API, and UI tests. It also describes tools like Just-API and Pyresttest that can be used to test GraphQL and REST APIs respectively using YAML configuration files.
GA Test Automation
GA Test AutomationLINE Corporation This document discusses automating Google Analytics (GA) testing for LINE TODAY. It proposes using Robotframework with Appium to simulate user actions in the LINE app and confirm that GA events are recorded correctly. It provides details on initializing the GA Reporting API to retrieve reports and examples of dimensions, metrics, and sample report requests. Code snippets demonstrate how to set up a service account and get credentials to access the GA Reporting API. The goal is to test new features for side effects and avoid human errors by automating the process of validating GA events.
UI Automation Test with JUnit5
UI Automation Test with JUnit5LINE Corporation This document provides an overview of UI automation testing with JUnit 5. It introduces the JUnit 5 framework, including its architecture, annotations, extension model, parameter resolver, and life cycle. It also discusses how to configure JUnit 5 in Gradle projects. Additionally, it briefly mentions other tools that can be used for UI testing, such as Appium, Ayachan, Ayavue, and image recognition libraries. The document aims to help people understand and get started with JUnit 5 for UI test automation.
Feature Detection for UI Testing
Feature Detection for UI TestingLINE Corporation The document summarizes a test night event held by LINE Fukuoka to discuss UI test automation. The event covered testing browser, iOS, and Android applications using Selenium for browsers and Appium for mobile. Attendees learned about template matching and feature detection techniques for UI testing, including pixel-perfect template matching versus feature detection which is scale invariant and can match elements that are 30-200% different in size. The techniques discussed were demonstrated using A-KAZE feature detection with OpenCV3 in Java.
