Introduction to Mobile UI Test Automation @vchimev @SvetoslavTsenov About Us Svetoslav Tsenov Vasil Chimev F O O D Do you test your mobile apps? Usual Excuses Not enough time No appropriate not reinvent the wheel Not modify app under test Cross-platform tests Scale Appium Open source mobile testing framework Not modify app under test Use language of choice Use known APIs (webdriver) greatly Aware of issues in 10 to 30 min per app Heavily testing on pull requests Numbers > 10 real test devices > 15 build machines (10 OS X, 4 Linux, 3 Windows) > 2000 tests > 600 CI jobs > 8000 images

polling even when network is idle. • Why not use a pure eBPF service? • Not mature enough eBPF brief • Write C • Compile into eBPF assembly code • Inject to kernel • Attach to network tc hooks • Triggered Performance of a cluster in different time slot may differ • Due to CPU oversold • Suggestion: • Run the test against the same cluster during near time • Make CPU the bottleneck • 1 CPU handles 500,000 pps measurement Test topology Test result Service type Short connection cps Short connection P99 latency Long connection pps ClusterIP +40% -31% not available NodePort +64% -47% +22% Test result • Perf

Serverless The Weapons Web3 Utilizes For mainstream tech stack, e. g. Ethereum ➔ A world-wide unified network to provide a serverless layer • A single-core CPU machine • Is serverless really the next stage have the chance to download/sync all open data from this platform ➔ On the server side, it is a network, consisting of some/many nodes ➔ Every node has a blockchain node in it What An Open Data App Feels to develop Open Data Application The EightFish Application Components The EightFish Application Network Topology How to Write Logic How to Write Logic How to Write Logic ➔ Docker compose, yaml configure

src/*.cpp) • 疑问 1 ：都是按照通配符批量匹配文件，有什么区别？ • GLOB ： src/main.cpp （√） src/test/main.cpp （ × ） • GLOB_RECURSE ： src/main.cpp （√） src/test/main.cpp （√） • 区别在于 GLOB_RECURSE 允许 * 匹配嵌套的目录。 • 疑问 2 ：加了 CONFIGURE_DEPENDS 包括动态库文件的位置，头文件的目录，链接时需要开启的编译选项等等。而且某些库都 具有多个子动态库，例如 Qt 就有 libQt5Core.so 、 libQt5Widgets.so 、 libQt5Network.so 。因此 CMake 要求所有第三方 库作者统一包装成一个 Qt5Config.cmake 文件包含所有相关信息（类似于 nodejs 的 package.json ），比你单独的一个个去找动态库文件要灵活的多。
