Why use iOS automation testing tools?

Your iOS app must work flawlessly on 28.33% of the world’s mobile devices. Apple has more than 2.2 billion active devices in the world, and iOS powers a significant number of them amongst macOS, watchOS, iPadOS. App builders must run comprehensive automated tests before even considering a release to appeal to such a huge user base.

Using iOS Automation testing tools within any SDLC is essential because:

• Faster execution times, which are necessary because your app must be tested on hundreds of devices for good coverage.
• Re-run tests as often as needed to address complex iOS bugs.
• Rapid feedback loops, helping developers find and fix bugs quickly.
• Eliminates issues arising from human error.
• Enables comprehensive test coverage across multiple scenarios, devices, screen sizes and iOS versions.
• Allows for early bug detection, which directly contributes to faster time-to-market.
• Delivers better-quality iOS software, as more tests can be run in existing timelines.

Which iOS automation testing tool should you pick in 2025?

I would pick the top choice for this list - BrowserStack. Here’s why:

BrowserStack met every requirement for most automated app testing projects my team and I undertook. The handy features are:

• Earliest possible access to new iOS devices. That really sets you ahead of the competition.
• It was easy to test native iOS device and app features, which I could not do on most other testing platforms.
• Integration is simple and quick whether you’re working with Appium, Espresso, XCUITest, Flutter, or Detox.
• It is very easy to test on dev servers and internal staging environments behind firewalls, with no setup or extra configuration.
• Hassle-free app uploads. Either upload a new build or query your recent builds with REST API.
• Plenty of legacy iOS devices to choose from.
• Easy setup to run parallel tests as needed.

I recommend trying out the free demos of every tool on this list (or at least the top 5) before making your decisions. I did the same, and it was BrowserStack’s device cloud and the quality of features/service that convinced me.
