We started by running the tests over and over locally so we could see what was failing. They were failing frequently on our Bitrise workers, and we didn’t run them locally very often. Our integration tests are written with the KIF framework, a similar framework to UI testing, which accesses a running application using the accessibility layer. Our most immediate problem by far was that the integration tests would fail intermittently. We prioritized our build issues and got to work. The last thing a Product Owner wants to hear is that you’re going to spend a few sprints working on the build, not fixing any bugs or building features! We couldn’t spend entire sprints fixing things up, so we had to tackle our problems one at a time.
Bitrise would completely perform our release builds, including submitting it to our beta testers and the App Store. We would move away from integration tests (slow) and lean more heavily on unit tests (fast). Bitrise build times to improve as well. Bitrise would run all our tests smoothly, with at least 95% reliability. Our dream environment looked a little like this: Since all PagerDuty employees dogfood the mobile apps, we were always updating a list of UDIDs! Ouch. We were still distributing test builds through Fabric, which is a great system, but it was an extra system we could replace with TestFlight. Actual release builds involved running some steps on developer machines, and required a pull request each time. Our CocoaPods dependencies were out of date and we didn’t feel comfortable updating them all at once. We couldn’t be sure that we weren’t breaking things when we made changes. The automated builds took over 20 minutes to run on Bitrise (our CI system). They failed about half the time and we weren’t sure why. We had very few unit tests and our integration tests were done with KIF. Here’s a list of the problems and the pain we were experiencing: Apps tend to need a lot of care, given that Apple changes the rules every year, and your dependencies don’t stay still either. Cara Bousie told Defense News the Air Force "does not anticipate additional testing will be required to demonstrate engine power" after discussing the matter with the FAA.I started at PagerDuty during a time of revitalization of the iOS app. Responding to the report at the time, Air Force spokeswoman Maj. The GAO said Boeing had noted that the FAA could require additional testing - resulting in potential schedule delays and increased costs - to demonstrate the engine's power before it can certify the helicopter's airworthiness. "If an appropriate weight is not achieved, the aircraft may not be able to meet requirements for speed or range," it added. "However, the helicopter, as it is currently designed, may not be able to meet all performance requirements if the final weight of the aircraft exceeds design parameters. "The program completed its critical design review in June 2019 - five months ahead of schedule," the GAO said in the report. That same month, the Government Accountability Office, or GAO, issued a report stating the helicopter's final speed and range requirement may not be met because of its weight. In February 2020, the service completed its first combined test flight of the multi-mission helicopter with a Boeing pilot at the helm.īut last June, Inside Defense reported that the MH-139 had not obtained another crucial FAA certification that dictates when the aircraft can begin additional military flight tests. 
Military pilots began flight training in early 2019 on the commercial AW-139 to receive certification to fly the military helicopter. The command's Detachment 7 is at Duke Field to support testing and evaluation of the new helicopter. The helicopter will be used for aerial protection of missile sites under Air Force Global Strike Command.
The service took delivery of its first MH-139 at Duke Field, Florida, in December 2019. The aircraft is based on the AW-139, Leonardo's commercial version of the helicopter.Īir Force officials on Friday did not disclose the reason for the certification delays.
Last year, the Air Force requested $212 million for the first low-rate initial production of eight MH-139 helicopters, manufactured in partnership with Leonardo.
