<content type="html"><![CDATA[<p>Today we're proud to announce the new major release, <strong>Detox 20</strong> (codename "Ashán"), which brings:</p><ul><li>official support for Genymotion SaaS</li><li>improved integration with test runners</li><li>configurable logging subsystem</li><li>headless mode for iOS via configs and CLI</li><li>reversing TCP ports via Android app configs</li><li>and more optimizations to land in the next minor versions.</li></ul><h2 class="anchor anchorWithStickyNavbar_LWe7" id="genymotion-saas">Genymotion SaaS<a href="#genymotion-saas" class="hash-link" aria-label="Direct link to Genymotion SaaS" title="Direct link to Genymotion SaaS">​</a></h2><p><strong>Highlights</strong>: <a href="/Detox/docs/guide/genymotion-saas"><code>Using Genymotion SaaS</code></a>.</p><p>Two years ago we <a href="https://github.com/wix/Detox/pull/2446" target="_blank" rel="noopener noreferrer">added elementary support</a> for cloud-based Android emulators provided by <a href="https://cloud.geny.io" target="_blank" rel="noopener noreferrer">Genymotion SaaS</a> and started a beta testing phase across mobile projects at Wix.</p><p>Previously our mobile infrastructure engineers had been maintaining Android virtual devices on CI build agents on their own, so switching to cloud devices cleared up their time for more productive tasks. Another improvement was particularly noticeable for teams with a vast number of tests. We could reduce the duration of their CI pipelines almost by half after they scaled up from 2 parallel devices to 6<sup id="fnref-1-2b8cfe"><a href="#fn-1-2b8cfe" class="footnote-ref">1</a></sup>.</p><p>This positive impact encouraged us to adopt <a href="https://cloud.geny.io" target="_blank" rel="noopener noreferrer">Genymotion SaaS</a> for CI as quickly as possible, ignoring some unresolved issues in the initial pull request. For the most part, those were minor problems in global lifecycle management. Yet that made us feel uncertain about releasing it as-is, so we decided to take time and gain more production experience before taking any direction.</p><p>The further experience was surprisingly smooth and rarely presented issues, spare for a few minor <a href="https://github.com/wix/Detox/issues/3573" target="_blank" rel="noopener noreferrer">glitches</a> in advanced scenarios. Admittedly, revamping the <a href="/Detox/docs/api/internals">Detox lifecycle</a> took us longer than expected, which is all the more reason for us to celebrate today.</p><p>We're looking forward to providing our users with more opportunities for testing in the cloud, and this step is only the first of many to come. We hope you'll utilize this new feature to your delight.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="integration-with-test-runners">Integration with test runners<a href="#integration-with-test-runners" class="hash-link" aria-label="Direct link to Integration with test runners" title="Direct link to Integration with test runners">​</a></h2><p><strong>Highlights</strong>: <a href="/Detox/docs/config/testRunner"><code>Config file &gt; Test runner</code></a>, <a href="/Detox/docs/api/internals"><code>Internals API</code></a>, <a href="https://github.com/wix/Detox/issues/3193" target="_blank" rel="noopener noreferrer"><code>Dropping Mocha support</code></a>.</p><p>It took about a few months of work to formalize the contract between Detox and a test runner. While there's still a lot of place for improvement, the new Detox release refines their interaction and lays the groundwork for third-party integrations.</p><p><a href="https://mochajs.org" target="_blank" rel="noopener noreferrer">Mocha</a> was our first supported test runner, but unfortunately, it could not keep up with our scaling requirements as the number of end-to-end tests grew. <a href="https://github.com/mochajs/mocha/releases/tag/v8.0.0" target="_blank" rel="noopener noreferrer">By the time</a> it acquired the ability to run tests in parallel, we already had <a href="https://github.com/wix/Detox/pull/609" target="_blank" rel="noopener noreferrer">to place bets</a> on another horse, and that was <a href="https://jestjs.io" target="_blank" rel="noopener noreferrer">Jest</a>.</p><p>We attempted to keep compatibility with both Jest and Mocha, but the farther we went, the more obvious it was that we couldn't have it both ways. As it turned out, Jest wasn't easy to get along with – our first integration with it was too simplistic. Over a couple of years of use in production, we kept discovering various issues that forced us to rewrite our "glue" code from scratch twice, and this isn't over yet. All combined didn't leave much time and energy for tinkering with Mocha anymore.</p><p>In this release, we discontinued Mocha support to focus on the attunement of Jest with the new runner-independent <a href="/Detox/docs/config/testRunner">test runner config</a> and <a href="/Detox/docs/api/internals">Internals API</a>. If there's enough demand, now it is up to the open-source community to build a new integration between Detox and Mocha.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="configurable-logger">Configurable logger<a href="#configurable-logger" class="hash-link" aria-label="Direct link to Configurable logger" title="Direct link to Configurable logger">​</a></h2><p><strong>Highlights</strong>: <a href="/Detox/docs/config/logger"><code>Config file &gt; Logger</code></a>, <a href="/Detox/docs/api/logger"><code>Logger API</code></a>.</p><p>The rigidity of the logging subsystem has always been showing itself <a href="https://github.com/wix/Detox/pull/835" target="_blank" rel="noopener noreferrer">since its very creation</a> in the summer of 2019.
Due to time constraints and existing tech debts, it was impossible to do it right the first time, so we lived about three years with a proof-of-concept rather than a full-fledged feature.</p><p>The inconveniences weren't fatal but quite noticeable, nevertheless. Here are a few syndromes you could have spotted if you have ever used Detox timeline and log artifacts, especially when running tests in parallel:</p><ul><li>an uncanny file array: <code>detox_pid_7505.log</code>, <code>detox_pid_7505.log.json</code>, <code>detox_pid_7506.log</code>;</li><li>a relatively shallow <code>detox.trace.json</code>: test suites, test functions, and some user-defined segments.</li></ul><p>The good news is that the new Detox release condenses all those numerous logs into two files:</p><ul><li>the plain, human-readable <code>detox.log</code>;</li><li>the raw, machine-readable <code>detox.trace.json</code> for <code>chrome://trace</code>, <a href="https://ui.perfetto.dev/" target="_blank" rel="noopener noreferrer">Perfetto</a> and other utilities.</li></ul><p><img loading="lazy" alt="A screenshot of timeline view generated by Perfetto"

This decision created a moderately annoying UX issue. Imagine you run tests sequentially first, using one worker only. That provides you with a regular AVD instance, i.e., not a read-only one. After that, you switch to multiple workers only to get an error from the Android emulator, complaining about mixing regular and read-only instances.</p><p>While the fix itself has always been straightforward – close the running AVD and try again – this entire overcaution brought more issues than solving them. That's why, from now on, Android emulators will always be starting in <code>-read-only</code> mode unless you configure <code>readonly: false</code> in your <a href="/Detox/docs/config/devices">device config</a>.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="reset-lock-file">Reset lock file<a href="#reset-lock-file" class="hash-link" aria-label="Direct link to Reset lock file" title="Direct link to Reset lock file">​</a></h3><p>This release adds a small CLI tool, <a href="/Detox/docs/cli/reset-lock-file"><code>detox reset-lock-file</code></a>, to help users with one specific use scenario.</p><p>Imagine you want to run tests for multiple Detox configurations at once, e.g.:</p><div class="language-bash codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#F8F8F2;--prism-background-color:#282A36"><div class="codeBlockContent_biex"><pre tabindex="0" class="prism-code language-bash codeBlock_bY9V thin-scrollbar"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#F8F8F2"><span class="token plain">detox </span><span class="token builtin class-name" style="color:rgb(189, 147, 249)">test</span><span class="token plain"> -c iphoneSE2020.release e2e/ui.test.js</span><br></span><span class="token-line" style="color:#F8F8F2"><span class="token plain">detox </span><span class="token builtin class-name" style="color:rgb(189, 147, 249)">test</span><span class="token plain"> -c iphone14ProMax.release e2e/ui.test.js</span><br></span></code></pre><div class="buttonGroup__atx"><button type="button" aria-label="Copy code to clipboard" title="Copy" class="clean-btn"><span class="copyButtonIcons_eSgA" aria-hidden="true"><svg viewBox="0 0 24 24" class="copyButtonIcon_y97N"><path fill="currentColor" d="M19,21H8V7H19M19,5H8A2,2 0 0,0 6,7V21A2,2 0 0,0 8,23H19A2,2 0 0,0 21,21V7A2,2 0 0,0 19,5M16,1H4A2,2 0 0,0 2,3V17H4V3H16V1Z"></path></svg><svg viewBox="0 0 24 24" class="copyButtonSuccessIcon_LjdS"><path fill="currentColor" d="M21,7L9,19L3.5,13.5L4.91,12.09L9,16.17L19.59,5.59L21,7Z"></path></svg></span></button></div></div></div><p>The problem is that Detox uses a file-locking mechanism to avoid situations when parallel test workers would take control of the same device.

While it never seemed to be a cakewalk, the entire experience of troubleshooting over a hundred issues across the organization did not leave us unchanged.</p><p>We see numerous things to improve in Detox, but most of them boil down to the same thing – <strong>scaling</strong>. Surprisingly, "scaling" makes an excellent umbrella term for nearly every challenge we've been encountering lately:</p><ul><li><em>scaling up the number of users</em> requires us to improve the onboarding and troubleshooting experience;</li><li><em>scaling up the number of projects</em> forces us to centralize scattered configs into flexible organization presets;</li><li><em>scaling up the number of tests</em> prompts us to optimize the codebase and incline it towards cloud and remote execution.</li></ul><p>Our core team has been facing challenges of limited human resource constraints and growing scaling needs for a long time. In many ways, that has shaped a specific mindset within the team. We evaluate every discussed feature by asking a simple question: <em>will it save other people and us time to focus on more important things?</em> Teaching a man to fish is better than giving fish, so our success at preventing support issues matters more than our success at solving them ourselves.</p><p>That's why we'll be making subsequent efforts in these three areas, hoping to get back to you soon with even more exciting updates.</p><p>Enjoy your drive with Detox 20!</p><p>Cheers! 👋</p><div class="footnotes"><hr><ol><li id="fn-1-2b8cfe">The mentioned threshold is not a hard limit, but rather a point where the return value of scaling up the number of devices starts dramatically diminishing in our case – not only the tests themselves, but installing NPM dependencies and building the projects also takes time.<a href="#fnref-1-2b8cfe" class="footnote-backref">↩</a></li></ol></div>]]></content>
