Running individual XCTest (UI, Unit) test cases for iOS apps from the command line

Question

Is it possible to run individual test cases, or individual test suites, from an iOS app test target, instead of all the test cases, from a command line interface?

Answer 1

I was in similar situation as you and have built a python script that triggers the set of test case/s that i want. Its a little bit elaborate process but works for me and has been very useful over time in implementing DataProvider methods, Rerunning of failed test cases and other customizations I required.

Some relevant steps for what you want to achieve.

1. Override testInvocations method present in XCTestCase to do below steps
   • In this method I read Environment Variable XXXX.
   • This environment variable is basically a comma separated test case method names.
   • Now create NSInvocations for each test method that you want to trigger.
   • Return array of Invocations.
2. How to pass Environment Variable?
   • In scheme add an environment variable named XXXX.
   • Scheme files are standard xml files, write a script that modifies the scheme file to contain the Comma separated values in environment variable.

If you require more info add a comment I will reply to it.
