Running Xcode tests

To run Xcode tests on Bitrise, you need to have test targets defined in your projects. You need two Steps to run Xcode tests and view their results:

Code signing files

Running Xcode tests and deploying their results to Bitrise do not require any code signing files. So don’t worry about them just yet!

The Xcode Test for iOS step runs the pre-defined Xcode tests. It has a default configuration that will work if the tests are written correctly. You can find the same configuration options in Xcode, too.

You can also generate code coverage files, and export the test results as a compressed zip file.

Test reports

Your Xcode test results will be exported to Test Reports: check out our Test Reports guide to find out how to make it work for you.

Configuring the Xcode tests on Bitrise

The default input values of the Xcode Test for iOS Step could work if your tests are written correctly. However, we recommend making sure that all the inputs have the value you want so the Step can do what you need!

Check the following required inputs of the Xcode Test for iOS Step before running a build. These inputs determine the sort of tests the Step will run.

Headless mode

From Xcode 9 onwards, tests are run in headless mode by default: this means that the simulator will run in the background only. To change it, go to the Step’s Debug input group and set the Run the test in headless mode? input’s value to no. However, with this option, tests will take more time.

Using xcpretty

The xcpretty output tool does not support parallel tests. If parallel tests are enabled in your project, go to the Step’s Debug input group and set the Output tool input’s value to xcodebuild.

Generating code coverage files

By default, the Xcode Test for iOS Step does not generate code coverage files. If you need them, however, it’s easy to change: just set the Generate code coverage files? to yes.

This sets two additional flags to the xcodebuild command:

xcodebuild GCC_INSTRUMENT_PROGRAM_FLOW_ARCS=YES GCC_GENERATE_TEST_COVERAGE_FILES=YES

If you run a successful build, code coverage files will be included in your results.

Exporting UI test artifacts

You can export the attachments of your UITest. These attachments include screenshots taken during the UI test, as well as any other artifacts that might have been generated. They are exported as a compressed zip file.

By default, the Xcode Test for iOS Step does not export artifacts of the UITest. If you want to export them, set the Export UITest Artifacts input of the Xcode Test for iOS Step to true.

You can check your test artifacts on the Test Reports page, along all additional results.
