|One, of many, of our beach rock finds.
So, over Twitter I gave a couple quick ideas on what to ask. Here is that list, expanded a little.
- What frameworks have they used to test iOS?
- Compare the differences between those frameworks.
- Go review this answer on stack overflow about iOS Testing. This will give you a rundown of the testing frameworks and tools for iOS.
- What are the pros of those frameworks? What are the cons? And the next question...
- Have they done UI Automation testing? How? What were the results of that testing?
- How do they manage their tests? It should be better than I don't. Tools used to track the tests to know what coverage you have is essential.
- How do they report on them? Not much good doing tests without being able to report on the results.
- What are the different granularities of tests and how have they used them in past positions? Which do they find the most useful for iOS?
- Unit Tests
- Functional Tests
- End To End Tests
- UI Automation Tests
- Manual/Adhoc Testing
- What difficulties have they had testing iOS?
- Or maybe the more blunt; What have they found to be unsuccessful or not of value when testing iOS?
- Ask this since it might highlight the one area you want to concentrate on they might hate.
- I have seen testers write great and sometimes not so great bug reports.
- How do they log a bug?
- What information is important?
- They should have an opinion on what to include.
- Most iOS apps use a web service back end of some kind. How do they test the results of web service calls?
- They should be saying Charles (or alternative packet sniffer like WireShark) here and using a proxy to sniff the HTTP packet flow.
- Whiteboard time
- Give them a simple method (Objective-C based please), just the definition and what the method is supposed to return.
- For example, something that takes a string and returns a sorted array that includes each unique word found in the string. I just has to be complex enough to cause them to write several examples.
- Ask them to write testcases for this method.
- Do they know the syntax of Test::Unit style or RSpec style?
- Can they program? If not, then you don't want them as an SDET. The whiteboard coding question should be a breeze for them.
- They should since the tools built on top of Apple's iOS testing frameworks are normally written in a scripting language.
- They will also need to integrate tests with build systems which means command line knowledge and the ability to script command line jobs.
That was the short list I came up with with some additions once I expanded on the brief Twitter exchange.
Anything else you'd look for or ask?
