Screenshot results are now clustered by screen so it's easier to compare rendering across devices in a test matrix. New physical devices added include the Sony Xperia XZ Premium, Moto G4 Play, and Huawei P8lite, while older unreliable devices are marked deprecated and removed after a month, visible in both the Firebase console and gcloud CLI. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are Robo scripts in Firebase Test Lab and how do they work? Robo scripts let a developer record a sequence of actions in an app, similar to Espresso Test Recorder, and play that recording back before Robo testing takes over automatically. The recorded output is a JSON file uploaded alongside the APK when running a Robo test, and it helps guide the automated test past login screens or app introductions that Robo alone struggles to navigate. _Teams automating Android UI tests can follow testing tool updates like this via daily.dev._ ### How does Firebase Test Lab handle device deprecation? Once a device is marked deprecated in Firebase Test Lab, it remains available for one month before being removed entirely. Deprecated devices are flagged in the Firebase console and shown with a red 'deprecated' tag in the gcloud command line output, giving teams time to update their test matrices before the device disappears. _Developers maintaining device test matrices can track deprecation timelines like this on daily.dev._ ## Similar posts on daily.dev - [Announcing Developer Device Platform \(DDP\) on Google Cloud](https://daily.dev/posts/announcing-developer-device-platform-ddp-on-google-cloud-tidii3izy) · Google Cloud · 0 upvotes · 0 comments - [3 Tips for Effective Snapshot Testing with Roborazzi](https://daily.dev/posts/3-tips-for-effective-snapshot-testing-with-roborazzi-1lkco7jab) · Atomic Spin · 0 upvotes · 0 comments - [Sauce Labs Launches Industry’s First Programmable Mobile Device Cloud for the AI Era](https://daily.dev/posts/sauce-labs-launches-industry-s-first-programmable-mobile-device-cloud-for-the-ai-era-bpn9zlx5u) · SD Times · 1 upvotes · 0 comments --- Tags: [#testing](https://daily.dev/tags/testing), [#android](https://daily.dev/tags/android) [View this post on daily.dev](https://daily.dev/posts/firebase-test-lab-december-2017-update-r2o7yynvz) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Firebase Test Lab December 2017 Update","url":"https://daily.dev/posts/firebase-test-lab-december-2017-update-r2o7yynvz","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/firebase-test-lab-december-2017-update-r2o7yynvz"},"datePublished":"2026-08-23T12:21:26.361Z","dateModified":"2026-08-24T07:09:29.463Z","description":"Firebase Test Lab introduces Robo scripts, letting developers record a sequence of actions (like Espresso Test Recorder) that play back before Robo takes over,...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Firebase","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Firebase","logo":"https://media.daily.dev/image/upload/s--i395oqZH--/f_auto,q_auto/v1787487448/logos/firebase-blog?_a=BAMAMicg0","url":"https://daily.dev/sources/firebase-blog"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/firebase-test-lab-december-2017-update-r2o7yynvz","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"testing,android","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Firebase","item":"https://daily.dev/sources/firebase-blog"},{"@type":"ListItem","position":3,"name":"Firebase Test Lab December 2017 Update"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/firebase-test-lab-december-2017-update-r2o7yynvz#faq","mainEntity":[{"@type":"Question","name":"What are Robo scripts in Firebase Test Lab and how do they work?","acceptedAnswer":{"@type":"Answer","text":"Robo scripts let a developer record a sequence of actions in an app, similar to Espresso Test Recorder, and play that recording back before Robo testing takes over automatically.
