    <p>For some of my iOS application projects, I would like my CI server to be able to report the following properties:</p> <ul> <li>startup time</li> <li>frame rate</li> </ul> <p>both as a graph over time, and with "low water marks" so the build fails if the measured results aren't within certain criteria. I've already found some of the things I need.</p> <ul> <li>The CI server will be Jenkins.</li> <li>I can use <a href="http://gamua.com/blog/2012/03/how-to-deploy-ios-apps-to-the-iphone-via-the-command-line/" rel="noreferrer">Transporter Chief</a> to get the built app onto an iPad.</li> <li>To measure the startup time I could find the duration between launching <code>main()</code> and leaving <code>application:didFinishLaunchingWithOptions:</code>.</li> <li>To measure frame rate I can put a <code>CADisplayLink</code> into the app and sample its <code>duration</code> property.</li> <li>If those tests output JMeter XML, then Jenkins can display the output via the <a href="https://wiki.jenkins-ci.org/display/JENKINS/Performance+Plugin" rel="noreferrer">Performance</a> plugin.</li> </ul> <p>What I haven't worked out is, how should I embed those tests into my app and launch it on the iPad? As described above I can <em>deploy</em> the app to the iPad, but then I don't know how I would launch it to gather the results of the tests. My unit tests are running on the simulator - I don't want to run the performance tests there obviously :-).</p> <p>I imagine that there's a solution involving jailbreaking the iPad and controlling the app over SSH, I'd prefer not to go down that route if it's possible. If you <em>have</em> done that and can explain how it works, I'd still like to hear about it.</p>

    1. COI know you dismissed the idea of performance testing in the simulator, but if you're interested in relative performance numbers or trends over time, that might be a decent stop gap. I have no idea how you'd launch the app automatically on a device :/

    2. CO@BenScheirman I don't trust any numbers I get from the simulator, even relative ones. "Hey this didn't get worse on my 8-core Mac with 20GB" doesn't tell me anything about behaviour on a first-gen iPad.

    3. COYeah you're right. Color me genuinely eager to see the results of this question :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
